Cemented and uncemented fixation are the two categories of fixation in hip arthroplasty (HA). While uncemented stems rely on biologic fixation, cemented HA uses PMMA (polymethylmethacrylate) to lend stability through an interlocking fit between the stem and the cancellous bone. The optimal choice of fixation in elderly patients is debatable. Although patients with poor bone quality have demonstrated good results with uncemented stems, recent improvements in cementing techniques have led to superior outcomes compared to those of older versions. We prefer fully cemented HA in elderly patients to achieve immediate stability that leads to early mobilization and minimal complications, such as intraoperative or postoperative periprosthetic femur fractures. This technical note describes cement fixation in HA.
