Urethral obstruction as a complication of staged bilateral triple pelvic osteotomy.

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.

Spontaneous femoral capital physeal fractures in adult cats: 26 cases (1996-2001).

OBJECTIVE: To determine clinical, radiographic, and histologic abnormalities in adult cats > 1 year old with spontaneous (ie, nontraumatic) femoral capital physeal fractures. DESIGN: Retrospective study. ANIMALS: 26 cats. PROCEDURE: Medical records of cats > 1 year old with femoral capital physeal fractures and no history of trauma were examined. RESULTS: Mean +/- SD age of the cats was 22.5 +/- 6.5 months. Twenty-five cats were neutered males. Mean weight of the cats was significantly greater than mean weight of a group of age- and sex-matched control cats. Of 16 cats for which age at the time of neutering was known, 14 had been neutered before 6 months of age. Nine cats had bilateral fractures. Severity of femoral neck osteolysis and sclerosis increased with increased duration of clinical signs. The contralateral femoral capital physis, distal femoral physes, and proximal tibial physes were radiographically open in 13 of 18,19 of 24, and 24 of 24 cats, respectively. Histologically, the epiphysis contained normal articular cartilage and bone, but attached growth plate cartilage lacked the normal columnar arrangement of chondrocytes. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that adult cats with spontaneous femoral capital physeal fractures were most likely to be heavier, neutered males with delayed physeal closure.
