Fixation of pelvic floor fractures in cats.

OBJECTIVES

To retrospectively evaluate the outcome of internal fixation of trauma- related pelvic floor fractures using a ventral abdominal approach in cats.

METHODS

Clinical examination and radiographic findings at presentation, after surgery, and at follow-up were assessed. Information gathered included concurrent injuries, surgical technique used, lameness and pain scores, and radiographic signs of implant stability.

RESULTS

Ten European shorthair cats were included in the study. Pelvic floor fractures were stabilised using locking plates in nine cats, and symphyseal separation was fixated using hemicerclage wire in one cat. Additional procedures included reduction of sacroiliac luxation in nine cats with positional screws placed in six cats, and plate stabilization of sacral fractures in one cat. All cats were able to walk within five days of surgery. No orthopaedic or neurological deficits were observed in seven cats at follow-up. Neurological deficits were observed in one cat. Signs of pain at implant sites due to inadequate surgical technique were noted in two cats. Anatomical reduction of the pelvic floor was achieved in eight cats.

CLINICAL SIGNIFICANCE

Stabilization of the pelvic floor and repair of sacroiliac luxation and other injuries by a ventral abdominal approach in cats led to an overall successful outcome. Fixation of the pelvic floor in cats with intact acetabular and ilial bones should be considered in patients with multiple pelvic fractures in combination with sacroiliac joint luxation or sacral fracture, pelvic canal narrowing, traumatic abdominal hernia, and other abdominal injuries.
