Surgical reduction and stabilization for repair of femoral capital physeal fractures in cats: 13 cases (1998-2002).

Abstract

OBJECTIVE: To evaluate anatomic reduction and surgical stabilization of femoral capital physeal fractures in cats. DESIGN: Retrospective study. ANIMALS: 13 cats. PROCEDURE: Medical records of cats with unilateral or bilateral femoral capital physeal fractures evaluated from 1998 to 2002 were reviewed. Age and weight of cats at the time of surgery; breed; sex; concurrent injuries; severity of lameness before and 1, 2, 4, 6, and 8 weeks after surgery; the amount of fracture reduction achieved and number of Kirschner wires (K-wires) used; degree of degenerative joint disease of the hip joint and lysis of the femoral neck and head observed after surgery; whether K-wires were removed after surgery; and complications after surgery were evaluated. RESULTS: Thirteen cats with 16 capital physeal fractures were identified. There was significant improvement in the severity of clinical lameness in all cats from weeks 1 through 4 after surgery. There was no correlation between the scores of the individuals who evaluated radiographs for fracture reduction and placement of K-wires. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that surgical stabilization and repair of femoral capital physeal fractures facilitate a short recovery period and a good prognosis for return to normal function in cats.
