Results suggested that adult cats with spontaneous femoral capital physeal fractures were most likely to be heavier, neutered males with delayed physeal closure.

Fifty-nine dogs with a total of 69 perineal hernias that were repaired by internal obturator transposition and polypropylene mesh reinforcement were reviewed. Thirty-six dogs were available for follow-up at a mean of 29.4 months postoperatively. Six dogs had complications within the first 60 days of surgery, such as perineal swelling, persistent tenesmus, and incisional infections. Twenty-two dogs had excellent outcomes; seven dogs needed continued medical treatment after surgery; and seven dogs had poor outcomes. Hernias recurred in five dogs. The incisional infection rate was 5.6%; the recurrence rate was 12.5%; and the overall success rate was 80.5% for the 36 dogs with long-term follow-up.

Twenty-six female beagles were used to evaluate the effects of intravenous and long-term subcutaneous administration of cephalothin, cefazolin, and cefmetazole on platelet function and the coagulation cascade. Platelet aggregation in response to an adenosine diphosphate (ADP) agonist, bleeding time, platelet count, platelet size, prothrombin time (PT), and activated partial thromboplastin times (aPTT) were evaluated before and 90 minutes after two intravenous doses (22 mg/kg) of cephalothin, cefazolin, and cefmetazole given at 90-minute intervals. Dogs given saline injections were used as controls. Platelet count, platelet size, PT, and aPTT were evaluated after 7 days of subcutaneous administration of saline, cefazolin, and cefmetazole (22 mg/kg every 8 hours). A significant decrease in platelet aggregation in response to ADP was detected 90 minutes after intravenous administration of cephalothin. Bleeding time was increased significantly 90 minutes after intravenous administration of cefmetazole. Platelet size was decreased significantly 24 hours after onset of the study in all animals, including controls. No significant changes in platelet count, platelet size, PT, or aPTT were detected after 7 days of subcutaneous administration. Cefazolin had no adverse effects on platelet aggregation in response to ADP, bleeding time, platelet count, platelet size, PT, or aPTT. Therefore, cefazolin should be considered as a perioperative antibiotic in dogs with conditions predisposing to hemostatic complications.

A 5-month-old, neutered male Labrador retriever developed urethral obstruction secondary to staged, bilateral, triple pelvic osteotomy procedures. Conventional medical therapy failed to resolve the urinary dysfunction, and eventual surgical correction was required. Prior anecdotal reports exist on this complication, but little to no information is available in the veterinary literature. It was the objective of this case report to document this rare complication and describe its correction.
