Öğe Anthropometric study of patients treated for clubfoot(Lippincott Williams & Wilkins, 2003) Kesemenli, CC; Kapukaya, A; Subasi, M; Necmioglu, S; Arslan, H; Ozbag, D; Çelik, YThe anthropometric characteristics of patients treated for clubfoot were used to investigate whether the dimensions of the foot were affected by the method of treatment. A total of 68 patients followed up for an average of 9 years were divided into three groups: group 1, conservatively treated; group 2, surgically treated; group 3, conservatively treated on one side and surgically treated on the other. The following average discrepancies in foot length were obtained: group 1, 0.91 cm; group 2, 1.5 cm; group 3, 1.09 cm. Toe lengths were shorter to the same extent as the other dimensions of the foot. These discrepancies were statistically significant. The following average discrepancies in foot width were obtained: group 1, 0.05 cm; group 2, 0.37 cm; group 3, 0.054 cm; these were insignificant. The authors believe that the degree of discrepancy may depend not solely on the method, but on the severity of the deformity as well.Öğe The effects of electromagnetic field on distraction osteogenesis(Yonsei Univ Coll Medicine, 2003) Kesemenli, CC; Subasi, M; Kaya, H; Sert, C; Büyükbayram, H; Arslan, H; Necmioglu, SThe effects of electromagnetic field on distraction osteogenesis and new bony tissue were investigated. Twenty-five New Zealand rabbits were divided into an experimental (12 rabbits) and a control (13 rabbits) group. An osteotomy was performed on the right tibia in the diaphyseal region in both groups. The experimental group was exposed to a magnetic field of 50 Hz 1.0 mT for 3 hours a day for 13 weeks. The control group was kept in a similar environment but with no electromagnetic field. The distraction was continued until an increase of 10 mm was achieved. At weeks 4, 8, and 13, radiography, scintigraphy, and a biopsy were performed in both groups, and the results were statistically analyzed. The X-ray results were similar in both groups at all times. On the other hand while the scintigraphic and histopathological results were similar at weeks 4 and 13 in both groups, the osteoblastic activity was significantly greater in the experimental group at week 8 (p<0.01). In conclusion an electromagnetic field increases the osteoblastic activity and osteogenesis, but has little effect during the remodeling phase.Öğe Is external fixation in pediatric femoral fractures a risk factor for refracture?(Lippincott Williams & Wilkins, 2004) Kesemenli, CC; Subasi, M; Arslan, H; Tüzüner, T; Necmioglu, S; Kapukaya, AThe aim of this study was to investigate whether external fixation is a risk factor for refracture by comparing the outcomes of children who received three different forms of treatment of femoral fractures. One hundred ninety-two patients treated for femoral fracture between 1990 and 1999 who underwent final examination were assessed. One hundred were treated with hip spica casting after traction, 57 with closed reduction and external fixation, and 35 with open reduction and external fixation. Morbidity results such as time to union, length of hospital stay, refracture, and wire site infection were statistically evaluated. Patients undergoing open reduction had a greater time to union and length of hospital stay and a higher refracture rate. The difference was statistically significant. Wire site infection occurred in all three groups; there was no statistically significant difference between groups. The authors concluded that external fixation is not a risk factor for refracture in the treatment of pediatric closed femoral diaphyseal fractures, and that it may be used with case in clinics with shortages of personnel and space.Öğe The role of melatonin as a link between head injury and enhanced osteogenesis(Churchill Livingstone, 2005) Kesemenli, CC; Necmioilu, SWe hypothesize that in the case of an individual with a head injury, melatonin can enhance osteogenesis. In virtually all species to date whether nocturnal or diurnal, melatonin is synthesized and secreted during the dark phase of the day. In traumatic subarachnoid hemorrhages, in the hypothalamic syndrome, the melatonin content was very high in liquor. This was determined by a fluorimetric method, especially modified for this purpose. Osteoblastic activity rises with the increase of melatonin. Heating of a fracture of Long or large bone can often be accelerated in patients with severe traumatic brain injury. However, a melatonin which could perhaps induce enhanced osteogenesis has not yet been identified. Melatonin might cause early bone heating and hypertrophic callus. (c) 2005 Elsevier Ltd.
