ABSTRACT
Total hip arthroplasty (THA) provides excellent pain relief and improves the functional activity of patients with debilitating arthritis of the hip. The success of the procedure depends on the surgeon’s ability to provide an implant with immediate stability that restores the biomechanics of the hip (3,4,6,15). Attainment of these surgical goals is limited by the fact that no single prosthesis is suitable for all patients because of individual variations in bone quality, bone anatomy, activity level, and the postoperative expectations of the patient. However, with thorough preoperative planning, these goals are attainable and any unexpected problems during surgery can be avoided.
