Core Tip

Core Tip: We evaluated the effectiveness and safety of the conjoined tendon-preserving posterior (CPP) approach for bipolar hemiarthroplasty (BHA) during a short-term follow-up. We retrospectively evaluated 80 patients who underwent CPP BHA implanted with cementless femoral protheses. We protected the posterior structures of the hip joint. We made a partial incision in the quadratus femoris muscle to increase exposure, thus making the surgical procedure more feasible. There was no dislocation or other adverse events observed during the early follow-up period. The CPP approach can effectively reduce dislocation after BHA and improve postoperative hip joint stability.
