Fig. 1. (A) The trial outer head with groove to minimize difficulty in trial reduction. The flat broaches made the neck osteotomy possible leaving the broach in place. (B) Trial reduction on the left hip hemi-arthroplasty. The piriformis was retracted posteriorly and the gluteus medius was retracted anteriorly. (C) The piriformis (P) and the gluteus medius (Me) were preserved after implantation.
