Öğe Application of vac in type III open fractures(Derman Medical Publ, 2018) Atic, Ramazan; Alemdar, Celil; Azboy, Ibrahim; Bulut, Mehmet; Cacan, Mehmet Akif; Gem, MehmetAim: Functional results of patients with Type III open long bone fractures treated with vacuum-assisted closure (VAC) and approximating sutures were evaluated. Material and Method: A total of 21 patients (4 female, 17 male with a mean age of 27 years, range: 3-64 years) with Gustilo-Andersen Type 3 open fracture were included in the study. The mean follow-up period was 25.67 months (range, 9-52 months). Thirteen patients had Type IIIB and eight patients had Type IIIC open fractures. Following a large debridement and irrigation in an operating room setting, wound dimensions were measured. Subsequently, VAC was applied. During the application, skin traction sutures were applied over the vacuum sponge. During the last dressing change in which a dean granulation tissue was obtained, the wound was closed following the measurement of its dimensions. Wound dimensions measured during the large debridement in the operating room were compared with the wound dimensions measured after the final VAC application. Results: Mean duration between trauma and operation was 7.57 hours (range, 2-23 hours). The wound was closed with delayed primary suturing in seven patients. In the remaining 14 patients, wound dimensions measured following the last VAC application were found to be decreased with a mean of 40.02% (range, 20-60%). Seven patients underwent a skin graft, two had a free flap application, four had a fasciocutaneous flap, and one had a fasciocutaneous flap + graft application. Two patients underwent revision operations for graft failure. Five patients (23.8%) developed a deep wound infection. The infections resulted in osteomyelitis in two patients (9.5%). Discussion; VAC application together with skin traction sutures in Type IIIB and C open fractures decreases wound size dimension of a graft or flap to be applied. Also it may reduce the requirement for secondary interventions.Öğe Bilateral periprosthetic tibial stress fracture after total knee arthroplasty: A case report(Elsevier Sci Ltd, 2016) Ozdemir, Guzelali; Azboy, Ibrahim; Yilmaz, BarisINTRODUCTION: Periprosthetic fractures around the knee after total knee arthroplasty can be seen in the femur, tibia and patella. The tibial fractures are rare cases. Our case with bilateral tibial stress fracture developed after total knee arthroplasty (TKA) is the first of its kind in the literature. PRESENTATION OF CASE: 75-year-old male patient with bilateral knee osteoarthritis had not benefited from conservative treatment methods previously applied. Left TKA was applied. In the second month postoperatively, periprosthetic tibial fracture was identified and osteosynthesis was implemented with locked tibia proximal plate-screw. Bone union in 12 weeks was observed in his follow-ups. After 15 months of his first operation, TKA was applied to the right knee. Postoperatively in the second month, as in the first operation, periprosthetic tibial fracture was detected. Osteosynthesis with locking plate-screw was applied and union in 12 weeks was observed in his follow-up. He was seen mobilized independently and without support in the last control of the case made in the 24th month after the second operation. DISCUSSION: The number of TKA applications is expected to increase in the future. The incidence of periprosthetic fractures should also be expected to increase in these cases. Periprosthetic tibial fractures after TKA are rarely seen. The treatment of periprosthetic fractures around the knee after TKA can be difficult. CONCLUSION: In the case of persistent pain in the upper end of the tibia after the surgery, stress fracture should be considered. (C) 2016 The Authors.

Methods: 50 female adult Sprague-Dawley rats were divided into five groups. Bilateral ovaeriectomy were performed in all groups except the sham-operated group. Groups were a sham-operated group and a control group (water was given), estradiol treated group (17-b estradiol 0.015 mg/kg per day), genistein treated group (genistein 10 mg/kg per day), and an estradiol/progesterone combination group (17-b estradiol 0.015 mg/kg plus drosperinone 0.028 mg/kg per day). The water or hormones were implemented in relevant groups for eight weeks by orogasthric catheter. The bone mineral density and biomechanical properties of the femur were analyzed. Results: Genistein, estradiol, and estradiol/progesterone groups increased bone mineral density significantly compared to the control group. In diaphysis and metaphysis bending test, all groups had higher peak load values than the control group. There were statistically significant differences between the estrogen/progesterone group and control group in diaphysis bending with regard to peak load. There were statistically significant differences between the estradiol and control groups in metaphysis bending with regard to peak load. In axial rotation test, all groups had higher peak torque values than the control groups. Conclusions: Genistein, estradiol and estrogen/progesterone combination improved the biomechanical properties of the ovariectomized rat bone. Genistein which has less side effects may be considered as an alternative in the treatment of postmenopausal osteoporosis.Öğe The changes in preferences for venous thromboembolism prophylaxis after total joint arthroplasty in Turkey: A survey(Turkish Joint Diseases Foundation, 2018) Azboy, Nesrullah; Cimen, Cgouzhan; Demirtas, Abdullah; Elci, Serhat; Azboy, IbrahimObjectives: This study aims to investigate the changes in preferences of orthopedic surgeons for venous thromboembolism (VTE) prophylaxis after total knee arthroplasty (TKA) and total hip arthroplasty (THA) and the factors that affect such changes in Turkey. Materials and methods: Turkish Orthopedics and Traumatology Association members (n=2.180) were invited to fill in the questionnaire. A total of 366 orthopedic surgeons responded and completed questionnaire. The questionnaire was comprised of 12 questions investigating the demographics of surgeons. their preferences for VTE prophylaxis. the changes in their preferences over the course of the past three years. and the causes of such changes. Results: In the past three years, 31.1% of surgeons changed their VTE prophylaxis method and 32.7% used risk classifications. The use of low molecular weight heparin (LMWH) decreased from 89.4% to 42.5% and from 85.8% to 44.2% after TKA and THA. respectively. The use of aspirin increased from 10.6% to 43.4% and from 9.7% to 37.2% after TKA and TIIA, respectively. The use of oral anticoagulants increased from 11.5% to 41.6% and from 10.6% to 39.8% after TKA and THA, respectively. Still, orthopedic surgeons in Turkey preferred LN1W11 at rates of 75.7% and 74% after TKA and Tim. respectively. Congressional presentations were the first (47.7%) among the causes of the changes in preferences for VTE prophylaxis. Preferences of up to 60% of surgeons working at universities were influenced by the American Academy of Orthopedic Surgeons guidelines. Conclusion: In the past three years, approximately one third of orthopedic surgeons changed their preferences for VTE prophylaxis after total joint arthroplasty in Turkey. Changes in preferences were largely in favor of aspirin and oral anticoagulants in parallel to changes in guidelines for VTE prevention.Öğe A comparison of proximal femoral locking plate versus 95-degree angled blade plate in the treatment of reverse intertrochanteric fractures(Turkish Joint Diseases Foundation, 2014) Azboy, Ibrahim; Demirtas, Abdullah; Gem, Mehmet; Cakir, Idris Ahmet; Tutak, YilmazObjectives: This study aims to compare the results of the proximal femoral locking plate (PFLP) and the 95-angled blade plate in the treatment of AO/OTA 31-A3 reverse intertrochanteric fractures with fracture line extending to the greater trochanter. Patients and methods: Forty-four patients with reverse intertrochanteric fracture which fracture line extending to the greater trochanter were retrospectively analyzed. Of those, 20 were treated with PFLP (PFLP group) and 24 were treated with ABP (ABP group). The AO/OTA classification was used for the classification of the fractures. Patients were assessed clinically and radiologically for the union at the fracture site and implant-related complications. Hip functions were evaluated with the Harris hip score. Results: The mean time to union was 17 weeks (range 14-28) and 18 weeks (range 16-32) in the PFLP group and ABP group, respectively. Implant failure and/or nonunion was observed in two patients (10%) in the PFLP group and in three patients (12%) in the ABP group. There was no statistically significant difference between the groups with regard to the Harris hip scores, time to union, need for reoperation due to mechanical problems, and complication rates (p > 0.05). Conclusion: Our study results show that these two fixation methods seem to produce similar results in the treatment of reverse intertrochanteric fractures with greater trochanteric comminution. However, we suggest that ABP still remains as a good choice with less expense in such fractures.Öğe Comparison of retrograde intramedullary nailing and bridge plating in the treatment of extra-articular fractures of the distal femur(Turkish Assoc Orthopaedics Traumatology, 2014) Demirtas, Abdullah; Azboy, Ibrahim; Ozkul, Emin; Gem, Mehmet; Alemdar, CelilObjective: The aim of this study was to compare retrograde intramedullary nailing (RIMN) and bridge plating for the treatment of extra-articular distal femur fractures. Methods: The study retrospectively examined 15 patients (13 males and 2 females; mean age: 36 years, range: 17 to 55 years) who underwent bridge plating and 13 patients (11 males and 2 females; mean age: 31.1 years, range: 17 to 49 years) who underwent RIMN for the treatment of extra-articular distal femur fractures between 2007 and 2012. Functional results were evaluated using the Sanders criteria. The mean follow-up time was 31.3 (range: 20 to 46) months and 26.7 (range: 18 to 62) months in the plate and the nail groups, respectively. Results: Mean duration until union was 25.7 (range: 12 to 72) weeks in the plate group and 22.3 (range: 12 to 52) weeks in the nail group. Nonunion was observed in 2 patients in the plate group and in 1 in the nail group, delayed union in 3 patients in the plate and 2 in the nail groups, malalignment (>10 degrees) in 2 patients in the plate group and 1 in the nail group and implant failure in 1 patient in the plate group. Excellent/good functional results were obtained in 12 and 10 patients in the plate and the nail groups, respectively. No significant difference was found between the groups in terms of duration of union, complications and functional results (p>0.05). Conclusion: Bridge plating and RIMN have similar results in the treatment of extra-articular distal femur fractures. Both methods can be applied to all fractures, with the exception of Gustilo-Anderson Type 3B and C open fractures.Öğe Comparison of soft-tissue and bone surgeries in the treatment of developmental dysplasia of the hip in 18-24-month-old patients(Lippincott Williams & Wilkins, 2013) Bulut, Mehmet; Karakurt, Lokman; Azboy, Ibrahim; Demirtas, Abdullah; Ersoz, Galip; Belhan, OktayThe aim of this study was to compare soft-tissue and bone surgeries in 18-24-month-old patients with developmental dysplasia of the hip (DDH). A total of 77 hips of 53 patients were analyzed. Soft-tissue surgery was performed in 31 hips of 25 patients. In the final examination, 23 hips, excluding hips of eight patients who underwent secondary bone surgery, were evaluated (group I). Bone surgery was performed on 46 hips of 28 patients (group II). In group I, the acetabular index was 41 degrees preoperatively and was 20.4 degrees in the final examinations. In group II, the acetabular index was 42 degrees preoperatively and was 15 degrees in the final examinations. To avoid unnecessary surgeries and complications, soft-tissue surgery should be preferred for DDH in 18-24-month-old patients.Öğe A comparison of the anteromedial and transtibial drilling technique in ACL reconstruction after a short-term follow-up(Springer, 2014) Azboy, Ibrahim; Demirtas, Abdullah; Gem, Mehmet; Kiran, Seymuz; Alemdar, Celil; Bulut, MehmetThe purpose of this study was to compare clinical and radiological outcomes of patients who underwent single-bundle anterior cruciate ligament (ACL) reconstruction with anteromedial portal (AMP) and transtibial (TT) techniques. Arthroscopic single-bundle ACL reconstruction was performed using AMP technique in 34 patients and TT technique in 30 patients. The patients were evaluated retrospectively. Aperture fixation was used for femoral fixation, and absorbable screws and U staples were used for tibial fixation of the graft. Pivot shift test, Lachman test, Lysholm, Tegner, and International Knee Documentation Committee (IKDC-2000) scoring systems were used in the clinical and functional evaluation of patients before and after the surgery. Time to return sports and activity level were assessed. In the radiological evaluation of non-anatomic bone tunnel placement, the criteria developed by lllingworth et al. were used. The mean duration of follow-up was 20.4 and 24.6 months in the AMP and TT groups, respectively. There was a significant difference between the AMP group (86.7 %) and the TT (14.7 %) group in terms of anatomical placement of the femoral tunnels and grafts (p < 0.001). No significant difference was observed between the two groups in terms of the Pivot shift test, Lachman test, Lysholm, Tegner, and IKDC scores, and activity level (p > 0.05). The patients in the AMP group returned to sports 1.5 months earlier on average (p < 0.001). It was shown that AMP technique was superior to the TT technique in providing anatomical placement of the graft and in recovery time to return sports; however, there was no difference between groups in early periods in terms of the clinical and functional outcomes.Öğe The comparison of triceps-reflecting anconeus pedicle and olecranon osteotomy approaches in the treatment of intercondylar fractures of the humerus(Turkish Assoc Trauma Emergency Surgery, 2016) Azboy, Ibrahim; Bulut, Mehmet; Ancar, Cahit; Demirtas, Abdullah; Ozkul, Emin; Gem, Mehmet; Karadeniz, HilmiBACKGROUND: This study aimed to evaluate the functional outcomes of patients with intra-articular distal humerus fractures treated with triceps-reflecting anconeus pedicle (TRAP) and olecranon osteotomy. METHODS: Forty patients with intra-articular distal humerus fractures were retrospectively analyzed. TRAP approach was used in 22 patients (12 males, 10 females; mean age 37.8 years, range 17-70), and olecranon osteotomy in 18 patients (11 males, 7 females; mean age 35.4 years, range 18-62). Fractures were classified using the AO/ASIF classification. Functional results were evaluated with the Mayo elbow performance score (MEPS) and the Disabilities of Arm, Shoulder and Hand (DASH) questionnaire score. RESULTS: The overall mean arc of elbow motion was 108 degrees (range 70 degrees-140 degrees) in the TRAP group, whereas that of the olecranon osteotomy group was 98 degrees (range 70 degrees-115 degrees). A significant difference was observed between the two groups in terms of overall mean arc of elbow motion (p=0.038). There were no significant differences noted between the two groups in terms of mean MEPS and DASH scores (p=0.412, p=201, respectively). The overall complication rate was 27.2% in the TRAP group and 55% in the olecranon osteotomy group. CONCLUSION: TRAP is a succesful approach in the treatmet of intra-articular distal humerus fractures that provides better arc of elbow motion, reduces complications and reoperation rates.Öğe The effect of hyperbaric oxygen therapy on fracture healing in nicotinized rats(Turkish Assoc Trauma Emergency Surgery, 2014) Demirtas, Abdullah; Azboy, Ibrahim; Bulut, Mehmet; Ucar, Bekir Yavuz; Alemdar, Celil; Alabalik, Ulas; Akpolat, VeysiBACKGROUND: The aim of the present study was to investigate the effect of hyperbaric oxygen therapy on fracture healing in nicotinized rats. METHODS: Thirty-two rats were divided as follows: nicotinized group (1), hyperbaric oxygen group (2), nicotinized + hyperbaric oxygen group (3), and control group (4). For 28 days, nicotine was administered in Groups 1 and 3. Then, a standard shaft fracture was induced in the left femur of rats. Groups 2 and 3 underwent hyperbaric oxygen therapy for 21 days. At the end of the experiment, fracture site, left femur and whole body bone mineral content and density were measured. RESULTS: The radiological and histopathological scores of Group 1 were statistically significantly lower compared to Groups 2, 3 and 4, and there was no statistically significant difference between the Groups 2, 3 and 4. In a comparison between the groups, no statistically significant difference was found in terms of bone mineral content and density values measured at the fracture site, left femur and whole body. CONCLUSION: The negative effects of nicotine on fracture healing are eliminated with hyperbaric oxygen therapy, but hyperbaric oxygen alone does not cause significant changes in healing (radiologically and histopathologically).Öğe The effect of tourniquet and knee position during wound closure after total knee arthroplasty on early recovery of range of motion: a prospective, randomized study(Springer, 2016) Sukur, Erhan; Ozturkmen, Yusuf; Akman, Yunus Emre; Senel, Ahmet; Azboy, IbrahimThere is no consensus on the position of the knee joint while performing wound closure after total knee arthroplasty (TKA). Further, there are no studies focusing on the association between early functional outcomes and different wound closure strategies. Therefore, we investigated the effects of tourniquet and knee position during wound closure on early recovery of range of motion (ROM) after primary TKA. To our knowledge, this is the first study to evaluate the influence of both tourniquet and knee position during wound closure in primary TKA. One hundred-twenty eligible patients were consecutively enrolled in this study and randomly divided into four groups according to wound closure strategy. Wound closure was either performed with the knee in flexion at 90A degrees or in full extension, with the combination of an inflated or deflated tourniquet. Visual analogue score (VAS), knee ROM, ROM recovery, knee society score (KSS), and wound complications were evaluated in the early postoperative period. After the first postoperative week, ROM recovery in the group with knee in extension and inflated tourniquet was significantly lesser than the two groups with deflated tourniquets. Between the first and fourth postoperative weeks, ROM recovery in the group with knee inflection and deflated tourniquet was significantly higher than the two groups with knee in extension. After the first postoperative week, the visual analog score (VAS) for pain in the group with knee inflection and deflated tourniquet was significantly lesser than the two groups with inflated tourniquets. The differences in the outcomes between the four groups were not significant after the fourth postoperative week. The incidence of wound complications and KSS were not significantly different between the four groups. Following TKA, wound closure with the knee in flexion and after deflating the tourniquet significantly decreased postoperative pain and promoted the recovery of ROM in the early postoperative period.Öğe Effectiveness of Locking Versus Dynamic Compression Plates for Diaphyseal Forearm Fractures(Slack Inc, 2013) Azboy, Ibrahim; Demirtas, Abdullah; Ucar, Bekir Yavuz; Bulut, Mehmet; Alemdar, Celil; Ozkul, EminThis study compares the results of the locking compression plate (LCP) and the dynamic compression plate (DCP) in the treatment of diaphyseal forearm fractures in adults and defines the indications for the use of the LCP. Forty-two patients with diaphyseal forearm fractures were retrospectively analyzed. Of those, 22 had been treated with the LCP (LCP group) and 20 had been treated with the DCP (DCP group). The AO/ASIF classification was used to classify the fractures. Patients were assessed using the Grace-Eversmann criteria and the Disabilities of the Arm and Shoulder and Hand questionnaire during the final follow-up. Mean follow-up was 21 months (range, 20-24 months) in the LCP group and 23 months (range, 19-26 months) in the DCP group. Union was achieved in all patients. Mean time to union was 15 weeks (range, 12-25 weeks) in the LCP group and 17 weeks (range, 13-24 weeks) in the DCP group. In each group, 1 patient experienced delayed union, which required no additional surgical intervention. No significant difference was found regarding the time to union between the groups (P>.05). No significant difference existed between the 2 groups in terms of Grace-Eversmann criteria and Disabilities of the Arm and Shoulder and Hand scores (both P>.05). The results of these different fixation methods for forearm fractures in adults are similar. As such, the correct selection and application of surgical technique is more important than the type of plate used.Öğe Effects of enoxaparin and rivaroxaban on tissue survival in skin degloving injury: an experimental study(Turkish Assoc Orthopaedics Traumatology, 2014) Azboy, Ibrahim; Demirtas, Abdullah; Bulut, Mehmet; Alabalik, Ulas; Ucar, Yavuz; Alemdar, CelilObjective: The aim of this study was to evaluate the effects of the antithrombotic agents enoxaparin, and rivaroxaban on tissue survival following skin degloving injury in an experimental rat tail model. Methods: The study included 24 rats divided into three equal groups of 8; the enoxaparin group (Group 1), the rivaroxaban group (Group 2) and the saline control group (Group 3). A degloving injury was created by making a circular incision 5 cm distal to the base of the tail; manual traction was applied to the tail skin distal to the incision. After 15 minutes, the ends of the incision were sutured back in place. Antithrombotic agents were administered immediately after suturing and repeated once a day for 15 days. At the end of Day 15, the experiment was terminated. Gross morphological tissue survival and histopathology were evaluated. Results: Histopathological examination of the enoxaparin and rivaroxaban groups revealed that the skin was mostly normal or intact with minimal inflammation. The mean length of necrotic area was significantly higher in the saline group compared to the enoxaparin and rivaroxaban groups (p < 0.05). No statistically significant differences were noted between the rivaroxaban and enoxaparin groups (p=0.451). The mean extent of skin necrosis was significantly higher in the control group than the study groups (p < 0.05), while there was no significant difference in the length of necrotic area between Group 1 and 2 (p=0.722). Conclusion: Rivaroxaban and enoxaparin improved tissue survival in skin degloving injuries in terms of gross morphological and histopathological findings in a rat tail model.Öğe Internet and social media usage of orthopaedic patients: A questionnaire-based survey(Baishideng Publishing Group Inc, 2017) Duymus, Tahir Mutlu; Karadeniz, Hilmi; Cacan, Mehmet Akif; Komur, Baran; Demirtas, Abdullah; Zehir, Sinan; Azboy, IbrahimAIM To evaluate social media usage of orthopaedic patients to search for solutions to their health problems. METHODS The study data were collected using face-to-face questionnaire with randomly selected 1890 patients aged over 18 years who had been admitted to the orthopaedic clinics in different cities and provinces across Turkey. The questionnaire consists of a total of 16 questions pertaining to internet and social media usage and demographics of patients, patients' choice of institution for treatment, patient complaints on admission, online hospital and physician ratings, communication between the patient and the physician and its effects. RESULTS It was found that 34.2% (n = 647) of the participants consulted with an orthopaedist using the internet and 48.7% (n = 315) of them preferred websites that allow users to ask questions to a physician. Of all question-askers, 48.5% (n = 314) reported having found the answers helpful. Based on the educational level of the participants, there was a highly significant difference between the rates of asking questions to an orthopaedist using the internet (P = 0.001). The rate of question-asking was significantly lower in patients with an elementary education than that in those with secondary, high school and undergraduate education (P = 0.001) The rate of reporting that the answers given was helpful was significantly higher in participants with an undergraduate degree compared to those who were illiterate, those with primary, elementary or high school education (P = 0.001). It was also found that the usage of the internet for health problems was higher among managers-qualified participants than unemployed-housewives, officers, workers-intermediate staff (P < 0.05). CONCLUSION We concluded that patients have been increasingly using the internet and social media to select a specific physician or to seek solution to their health problems in an effective way. Even though the internet and social media offer beneficial effects for physicians or patients, there is still much obscurity regarding their harms and further studies are warranted for necessary arrangements to be made.Öğe Intramedullary Titanium Elastic Nailing in the Treatment of Paediatric Diaphyseal Femur Fractures(Aves, 2013) Sukur, Erhan; Azboy, Ibrahim; Demirtas, Abdullah; Bulut, Mehmet; Ucar, Bekir Yavuz; Alemdar, CelilObjective: We evaluated the clinical and radiographical outcomes in paediatric patients with diaphyseal femur fractures who were treated with intramedullary titanium elastic nails. Methods: Twenty-two patients (15 boys, 7 girls; mean age 7.6 years; range 6 to 12 years) with diaphyseal femur fractures who were treated with retrograde titanium elastic nailing (TEN) were evaluated in the study. 15 of the fractures were located mid-diaphyseally, 4 proximal diaphyseally and 3 distal diaphyseally. Open reduction via lateral incision was applied in cases in which closed reduction could not be achieved. Anterior-posterior and lateral radiographical views of the femur were used in the follow-up period. Gait patterns, range of motion of the knees and the hips, hospitalization time, time to union, limb length discrepancy between the lower extremities, and any complications were evaluated in the patients. Flynn's TEN scoring system was used to evaluate the outcomes. Results: Union was obtained in a mean of 6.8 weeks (range 5 to 11 weeks) in all of the patients. The anterior-posterior radiographs indicated that normal alignment was achieved in 19 patients. Two patients had a 5 degree varus malalignment and one had a 6 degree valgus malalignment. Two patients had a 6 degree anterior malalignment in the lateral radiographical view. Average limb length discrepancies of 7 mm were seen in 2 patients and of 6 mm were seen in 3 patients. Hip and knee motion were mildly restricted in one patient. Gait pattern was symmetric in all but one patient. Superficial wound infection was detected in one patient. None of the patients had nonunion, early closure of the epiphyseal plate or fracture following TEN extraction. Fifteen patients had excellent and 7 had good results according to Flynn's criteria. Mean hospitalization time was 4.2 days (range 3 to 9 days) and mean follow up period was 20.2 months (range 14 to 24 months). Conclusion: Intramedullary TEN is a successful method that yields good results for paediatric diaphyseal femoral fractures.Öğe Lengthening by distraction osteogenesis in congenital shortening of metacarpals(Turkish Assoc Orthopaedics Traumatology, 2013) Bulut, Mehmet; Ucar, Bekir Yavuz; Azboy, Ibrahim; Belhan, Oktay; Yilmaz, Erhan; Karakurt, LokmanObjective: The aim of this study was to present the results of seven cases of metacarpal lengthening by distraction osteogenesis and to discuss the ideal daily rate of distraction. Methods: Metacarpal lengthening was performed by distraction osteogenesis in the seven metacarpals of four patients (3 females, 1 male; mean age: 14.9 years). A unilateral external fixator was used for lengthening. Lengthening was initiated with a distraction rate of 2x0.5 mm/day in the patient with bilateral. involvement of the middle and ring metacarpals. On the tenth day of lengthening, distraction was discontinued due to pain and contracture. Then, distraction was continued with a rate of 2x0.25 mm/day. In all other cases, the distraction rate was 0.5 mm/day. Pre- and postoperative range of motion was measured with a goniometer. Patient satisfaction was evaluated with visual analog scale. Results: The mean pre- and postoperative metacarpal lengths were 34.6 pun (range: 33 to 37) and 49.7 mm (range: 47 to 52), respectively. The mean lengthening achieved was 15.1 mm (range: 14 to 17), while the Mean distraction rate was 0.55 mm/day (range: 0.48 to 0.63). No functional loss was observed in the fingers at the final check-up. The patients were happy with the functional and cosmetic results. Conclusion: Distraction osteogenesis is a safe method providing acceptable cosmetic and functional results in patients with congenital metacarpal shortness. The length of metacarpals and muscles that will be affected from lengthening should be considered when determining the daily rate of distraction.Öğe Long-term results of porous-coated cementless total knee arthroplasty with screw fixation(Turkish Assoc Orthopaedics Traumatology, 2013) Azboy, Ibrahim; Demirtas, Abdullah; Bulut, Mehmet; Ozturkmen, Yusuf; Sukur, Erhan; Caniklioglu, MustafaObjective: The aim of this study was to evaluate the long-term results of porous-coated, cementless total knee arthroplasty with screw fixation. Methods: This study included 68 knees of 54 patients (43 female, 11 male; mean age: 56.9 years, range 46 to 70 years). Cruciate-retaining cementless total knee prostheses were implanted in all patients diagnosed with primary osteoarthritis. Clinical, functional and radiological evaluations were performed according to the Knee Society's Knee Scoring System (KSS). Prosthesis survival was analyzed using Kaplan-Meier curves. Mean follow-up time was 9.2 (range: 8 to 12) years. Results: Preoperative mean knee and function scores were 42.3 (range: 32 to 61) and 39.1 (range: 35 to 66), respectively, while they were 88.6 (range: 54 to 96) and 82.8 (range: 50 to 100), respectively at the final follow-up (p<0.05). Mean preoperative knee flexion was 98 degrees (range: 80 degrees to 110 degrees) and 112 degrees (range: 85 degrees to 130 degrees) at the final follow-up (p<0.05). Preoperative and postoperative mean alignments were 9.2 degrees varus and 5.4 degrees valgus, respectively. Revisions were performed due to aseptic loosening of the tibial component in one patient, periprosthetic fracture in one and dislocation of the patella in one. Two superficial infections (3%) were observed. There was no osteolysis around the screws during the follow-up period. The overall rate of implant survival was 95.6% (range: 91.56% to 99.60%; 95% CI) at 12 years. Conclusion: Long-term outcomes of porous-coated, cementless total knee arthroplasty with screw fixation were successful in terms of clinical and radiological evaluation and yielded a high survival rate.Öğe Management of infectious fractures with Non-Contact Plate (NCP) method(Acta Medica Belgica, 2015) Alemdar, Celil; Azboy, Ibrahim; Atic, Ramazan; Ozkul, Emin; Gem, Mehmet; Kapukaya, AhmetThe aim of this study was to evaluate the outcomes of internal fixation with Non-Contact Plating (NCP) after deep infection caused by previous surgeries of the tibia or femur fractures. The study included 15 patients (4 female and 11 male). The mean age patients was 36.6 years (range, 21-64 years). There were 6 femur and 9 tibia fractures. The mean followup period was 25.7 months (range, 15-45 months). The study comprised 11 open and 4 closed fractures. External fixator was used in 3, plate in 4, and intramedullary nail in 8 patients for index surgery. Deep infection was diagnosed via clinical findings, laboratory parameters, and microbiological evaulation. Deep infection was diagnosed within a mean period of 5.5 weeks (range, 2-10 weeks). The infecting organism was methicillin-resistant staphylococcus aureus (MRSA) in 5, methicillin-sensitive staphylococcus aureus (MSSA) in 6, pseudomonas auroginosa in 2, and enterobacteriacea in 2 patients. Union achieved in all patients. Mean time to union was 17 (range, 1138) weeks. Delayed union was observed in 3 patients who required additional surgeries. Of these one patient developed osteomyelitis. The NCP is an effective alternative method in the treatment of deep infection encountered after internal or external fixation for the tibia, or femur fractures.Öğe Mid-term results of previously cemented hip arthroplasties revised with uncemented modular femoral components: a retrospective study(Biomed Central Ltd, 2015) Duymus, Tahir Mutlu; Solak, Zafer; Ozturkmen, Yusuf; Azboy, Ibrahim; Mutlu, Serhat; Caniklioglu, MustafaBackground: We evaluated the mid-term results of previously cemented hip arthroplasties revised with uncemented modular femoral components. Methods: The study included 40 patients (36 females (90 %) and 4 males (10 %), mean age 67.6 years, range 3987 years) who underwent revision of a previously cemented hip prosthesis with an uncemented modular femoral stem between 2005 and 2009. The indications for revision were femoral aseptic loosening in 38 (95 %) cases and acetabular protrusion in 2 (5 %). According to the Paprosky classification, the femoral defect was type 1 in 10 (25 %) patients, type 2 in 16 (40 %), type 3a in 11 (27.5 %), type 3b in 2 (5 %) and type 4 in 1 (2.5 %). The Harris hip score was used for the clinical evaluation. Femoral vertical subsidence, the cortical index and femoral stem stability were assessed radiologically. The mean follow-up period was 84 months (range 61-95 months). Results: The mean Harris hip score was 41.4 (range 35.4-44.4) preoperatively and 80.9 (range 65.6-98.3) at the final follow-up examination (p < 0.05). Mean vertical subsidence was 5.7 mm (range 2.5-10.5 mm) in seven (17.5 %) patients. Stable bone fixation was observed in 38 (95 %) patients, fibrous stable fixation in 2 (5 %) and no instability in any patient. Radiographs taken during the early postoperative period revealed that the cortical index was a mean of 1.34 (range 1.11-1.73) and a mean of 1.55 on the final follow-up radiographic examinations (range 1.16-1.91) (p < 0.01). Conclusions: Satisfactory results were achieved using uncemented modular femoral components during revision of previously cemented femoral components. Many modular femoral stems provide primary stability by filling femoral bone losses and help determine stem length, offset and anteversion.Öğe Minimally Invasive Plate Osteosynthesis in Open Pediatric Tibial Fractures(Lippincott Williams & Wilkins, 2016) Ozkul, Emin; Gem, Mehmet; Arslan, Huseyin; Alemdar, Celil; Azboy, Ibrahim; Arslan, Seher G.Objectives: The aim of this study is to investigate the effectiveness and reliability of limited-contact locking plates in minimally invasive percutaneous osteosynthesis (MIPO) of the lateral tibia. Design: A retrospective study. Patients and Methods: The retrospective study included 14 patients who were operatively treated with an MIPO technique due to open tibial fractures between 2006 and 2012. The patients were 11 males and 3 females with a mean age of 13.2 (range, 9 to 16) years. The patients were followed up for a mean period of 2.4 (range, 1 to 5) years. The mechanism of the injuries included a motor vehicle accident (n=11), a shotgun injury (n=2), and a fall from height (n=1). According to the Gustilo-Anderson classification, 10 patients had type I (72%), 2 had type II (14%), and 2 had type III (14%) open fractures. Results: The mean time to radiologic union was 18 (range, 11 to 32) weeks. No infection was detected that would require implant removal. No complications such as early epiphyseal closure, angulation, or limb-length inequality were observed. Conclusions: Limited-contact locking plates in MIPO of the lateral tibia is an effective alternative method in the treatment of open pediatric tibial fractures.
