Core Tip
Core Tip: Short stem total hip arthroplasties (THAs) are commonly used in young and active patients. The advantages of these stems include more proximal load transfer which reduces stress shielding and, thigh pain, and they provide better options should revision surgery become necessary. Subsidence is one of the concerning complications in cementless femoral fixation. It is particularly important to identify the key intraoperative decision criteria to predict post-implantation subsidence of the short stem, which should be useful for choosing the proper size and position of the short stem and for allowance of early weight bearing post-operatively. This study demonstrated that insufficient lateral stem contact was a statistically significant influencing factor on significant subsidence. Therefore, it is a particularly important step to create proper lateral cortical contact when performing the short stem THA.
