Substituição do ligamento redondo por membrana biológica e pino transarticular na redução de luxação coxofemoral bilateral em cães Substitution of femoral head ligament by biological membrane and transarticular pinnig in reduction of bilateral coxofemoral luxation in dogs

Coxofemoral luxation is the most common injury in pets. It’s generally caused by trauma, creating a rupture in ligament of the femoral head and capsule articulation. The clinical examination identifies the type of luxation and the severity of the injury, being of basic importance also for the systemic valuation of the traumatized animal. The final diagnostic it’s from a simple radiographic that help to direct the treatment. The object of this report is to mention a reduction of bilateral coxofemoral luxation where occurred a rupture of capsule and the ligament of the femoral head of a dog. The ligament of the left limb was substituted for autograft fascia lata flap and the right limb had fixed its articulation with a transarticular pinning, in experiment reduction. On left limb reluxation, the autograft fascia lata flap was substituted by equine central tendon preserved in glycerin 98%. The central tendon made possible the functional limb use in 15 days after the operation while the transarticular pinnig just on the 40 days of the postoperative. This report suggest that central tendon, in glycerin conservation, could be a viable alternative on reduction of coxofemoral luxation.
