Research progress in strategy of lateral femoral offset reconstruction in total hip arthroplasty / 中国骨伤

ABSTRACT

As an important indicator of total hip arthroplasty (THA) the rate and degree of offset reconstruction play an important role in improving the prognosis and life quality of patients. The reconstruction of femoral offset is closely related to reserved length of calcar femorale, the head and neck length of prosthesis, angle degree of neck shaft and whether lower limb is isometric. Reconstruction strategy includes making a meticulous and standard measurement before the surgery, predicting the reserved length of calcar femorale, selecting a prosthesis with approximate anatomical neck-shaft angle and reconstructing offset by adjusting the head and neck length of the prosthetic during the operation. The aim of this article was to introduce the research progress and influence of offset on hip function, prosthetic wear and postoperative complications such as pain, limp and unequal leg length, and to discuss the reconstruction strategy.
