Surgical stabilisation of distal femoral fractures in calves using a triple pin technique: Twenty-five cases.

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.

Diagnosis and Surgical Management of Congenital Laxity of the Fibularis Musculotendinous Unit Resulting in Hyperextension of the Tarsus in 14 Calves.

OBJECTIVE: To describe the diagnosis and surgical management of congenital laxity of the fibularis tendon resulting in hyperextension of the tarsus in calves. STUDY DESIGN: Case series. ANIMALS: Fourteen calves (3 unilateral, 11 bilateral) diagnosed with congenital tarsal instability caused by laxity of the fibularis musculotendinous unit resulting in hyperextension of the tarsus. METHODS: Diagnosis was made by clinical and radiologic assessments. The tarsus was surgically prepared and an incision made on the dorsal surface of the tarsus after intrathecal anesthesia with the calf sedated. A locking-loop suture (4 loops) was applied to the fibularis tendon using polyglactin 910. The free ends of the suture were then tied to the shank of a cortical bone screw inserted in the proximal metatarsus. RESULTS: The calves were evaluated on postoperative days 15, 30, and 60 and were walking normally. CONCLUSION: Congenital tarsal instability because of laxity of the fibularis musculotendoninous unit is described and surgical treatment directed at shortening the tendon shows promising results.

Effects of alpha lipoic acid on intra-abdominal adhesion: an experimental study in a rat model.

BACKGROUND: This study was performed to determine the effect of alpha lipoic acid, a powerful antioxidant, on intra-abdominal adhesion formation. METHODS: Twenty-four female Wistar Albino rats weighing 250-300 g were used in this study conducted on three groups consisting of the alpha lipoic acid group (Group I, n=8), control group (Group II, n=8), and sham group (Group III, n=8). After performing laparotomy with a midline incision under general anesthesia, the adhesion model was created on the antimesenteric side of the caecum in Group I and Group II. 50 mg/kg alpha-lipoic acid was administered intraperitoneally (IP) in Group I while the surgical procedure was performed but no drugs administered in Group II. Only laparotomy was performed in Group III. Rats were sacrificed at the end of the tenth day. RESULTS: Macroscopic scoring was performed, tissue samples were obtained and subjected to biochemical and histopathological evaluation. The degree of adhesion and malondialdehyde level decreased (p<0.01), and glutathione levels had increased (p<0.01) in Group I compared to Group II in macroscopic scoring. CONCLUSION: Alpha lipoic acid was found to significantly decrease (p<0.01) intra-abdominal adhesion when administered IP compared to the control group.

The comparison of the effects of ellagic acid and diclofenac sodium on intra-abdominal adhesion: an in vivo study in the rat model.

Peritoneal adhesions are seen frequently after abdominal surgery and can cause serious complications. We aimed to evaluate the effects of the oral use of diclofenac sodium and ellagic acid on formation of postoperative adhesions in rats Studies have shown that agents with anti-inflammatory properties and antioxidant substances can prevent adhesion by decreasing oxidative stress. We compared and evaluated the effects of ellagic acid that has strong antioxidant and anti-inflammatory properties and the nonsteroidal anti-inflammatory diclofenac sodium on peritoneal adhesion development in our experimental study. Laparotomy was performed with a midline incision under general anesthesia and an adhesion model was created on the antimesenteric side of the cecum in Groups I, II, and III. Group I received 85 mg/kg ellagic acid and Group II, 50 mg/kg diclofenac sodium through the nasogastric catheter while Group III received no medication. Only laparotomy was performed in Group IV. The rats were sacrificed at the end of the 14th day. Following macroscopic scoring, tissue samples were removed and subjected to biochemical and histopathologic evaluation. The degree of adhesion and the malondialdehyde level were decreased (P < 0.05), and glutathione level increased (P < 0.05) in Group I compared to Group II and Group III. The effects of ellagic acid on the prevention of peritoneal adhesion were found to be stronger than diclofenac sodium. This can be explained by the fact that ellagic acid is a strong antioxidant and decreases oxidative stress with anti-inflammatory and anti-angiogenic effects.
