    The purpose of this study is to assess clinical, MR, USG and histopathological findings of early and later results of polyester film use in experimental ventral hernia model in rabbits. In this study, 16 New Zealand rabbits were divided into 2 groups of 8 rabbits each. After xylazine HCl usage as a sedative, the surgery is conducted under general anaesthesia by ketamine HCl. Upon median skin incision, a 2 cm diameter round defect on linea alba level was formed in rabbits lying in the supine position. The defect was repaired with 4 cm diameter polyester film which had been prepared beforehand in the shape of a disc. After clinical follow up of 15 days for rabbits in group I and 60 days for group II, USG and MR images were taken, by re-laparotomy the presence and extent of peritoneal adhesion was examined visually. All data from the study were statistically assessed via Minitab-16 package program. Tissue samples from the graft area were stained through hematoxylineozin and Crossman’s triple dye and assessed by usage of light microscope. During histopathological examination, it was observed repair by fibrous tissue in the area where surgery was performed for all the animals in 15 day group. Neither foreign body giant cell reaction nor necrosis was observed in two groups. When clinical, USG, MR findings along with re-laparotomy, macroscopic and histopathological results are taken into account, it was seen that polyester film bore successful results with regards to ventral hernia therapy in rabbits. Based on the data provided by this study, it is decided that the mentioned material should be tried for large hernia defect repair in domestic animals.

    Surgical stabilisation of distal femoral fractures in calves using a triple pin technique: Twenty-five cases
    (John Wiley and Sons Inc, 2023) Kılıç, Engin; Yayla, Sadık; Ermutlu, Celal Şahin; Baran, Vedat; Özba, Burhan; Aydın, Uğur; Yıldız, Uğur
    Background: The goal of this study was to develop a safe fixation technique for the effective treatment of supracondylar and distal diaphyseal femoral fractures in newborn calves. Methods: This study included a total of 25 newborn calves diagnosed with supracondylar or distal diaphyseal femoral fractures based on anamnesis and clinical and radiographic examination findings. Operations were performed under intrathecal anaesthesia. During the operation, the fracture line was found, and fixation was achieved by placing two Steinmann and Schanz pins. Results: No abnormal findings were seen in the radiographs performed 28 days after surgery, and it was determined that a hard callus had started to form. It was observed that the patients who had lightly stepped on the ground for the first 3 days after the operation were able to walk without any problems on day 28. Limitations: As this study involved neonatal calves aged 1–14 days, the operation could only be performed under spinal anaesthesia with no sedation. However, sedation is likely to be applied in addition to spinal anaesthesia in older calves. Conclusion: It was concluded that the triple pin technique can be safely used in the treatment of supracondylar and distal diaphyseal femoral fractures.

    Unilateral spinal anaesthesia in calves
    (Hellenic Veterinary Medical Society, 2019) Yayla, Sadık; Kılıç, Engin; Aydın, Uğur; Özaydın, İsa; Baran, Vedat; Kamilog̈lu, Alkan
    In this study, we aimed to evaluate the effects of unilateral anaesthesia by the administration of hyperbaric bupivacaine through the lumbosacral space into the subarachnoid space in calves. A total of 10 calves with unilateral femoral fractures were included in the study. After each calf was placed in a lateral position on the side intended for surgery, 15 mg of hyperbaric bupivacaine was slowly injected into the subarachnoid space. The onset, duration and depth of anaesthesia were determined by the pinprick test (scale 1-4). In addition, heart rate, diastolic arterial blood pressure, systolic arterial blood pressure, mean arterial blood pressure, respiratory rate and body temperature of the calves were monitored and recorded from the onset to 120 min after anaesthesia. The onset of unilateral spinal anaesthesia was within 20 s and the mean duration of anaesthesia was 155.40 min. Although there were statistical differences between hemodynamic values in the study, they were within the reference values. As a result, we believe that unilateral spinal anaesthesia in calves provides adequate anaesthesia for use in orthopaedic procedures; thus, it can be used in practice.
