Necrose asséptica da cabeça do fêmur em cão: relato de caso

Abstract

Aseptic femoral head necrosis (NACF) is a noninflammatory, non-contaminated condition that previously elapses from the bone closure. Necrosis is caused by the reduction in blood flow to the femoral epiphysis, but its etiology is not completely understood. The treatment of choice is surgical, and the technique of excisional femoral head and neck arthroplasty is the most used. Was attended at the University Hospital of Veterinary Medicine of UFRB, a cross-bred bitch was reported, reporting her left pelvic limb, pain on palpation and no history of trauma. Physical evaluation showed a reduction in abduction and lower capacity of extension of the affected limb. The radiographic examination requested revealed a change in the femoral head region indicative of NACF. The chosen treatment was the surgical technique for femoral head excision, being necessary to return to the surgical block later to remove the remaining fragment. In the late postoperative period, the efficiency of the technique can be verified, since the animal was already walking with minimal lameness and no pain manifestation.
