Clinical and radiographic evaluation of subsidence in two femoral stem models for a total hip replacement in dogs.

Canine cementless total hip arthroplasty (THA) is a successful technique for the management of hip arthrosis; however, serious potential complications, such as femoral fractures and subsidence of the femoral stem, can occur. To evaluate the effect of two femoral stem designs in reducing subsidence in dogs, twenty-four hips from twenty-one dogs undergoing THA were assessed. The twenty-four arthroplasties were divided into two experimental groups: G1 with a first generation, and G2, which is the second generation, system were used.

Biomechanical evaluation of a new femoral stem design for total hip replacement in a canine model.

Purpose: To evaluate the biomechanical properties of a novel total hip replacement femoral stem.

Methods: Eight pairs of femurs from dog cadavers were used. The femurs were separated into different groups.
