Abstract

The results of hemiarthroplasty for shoulder fracture were evaluated in 26 patients, 20 women and 6 men with a mean age of 64.7 +/- 8.2 years. The follow-up period was 2 to 7 years. Cofield prostheses were used for the first 10 patients and subsequently 9 Global and 7 Aequalis prostheses were implanted, all cemented. The clinical outcome was assessed using the Constant-Murley scale. The mean score, at the last follow-up, was 70.4 +/- 16.4 (39-96). Mean forward elevation of the arm was 150 degrees (300-175 degrees), mean abduction was 145 degrees (30 degrees -170 degrees), and mean external rotation was 30 degrees (10 degrees-45 degrees). In most of the cases internal rotation corresponded with a position of the dorsum of the hand at the L3 vertebrae. The patients in our series achieved their optimal clinical result within the first 6 months after operation. Shoulder hemiarthroplasty is a worthwhile procedure, giving predictable results provided the patients have been carefully selected, the individual anatomy of the shoulder is restored and an aggressive rehabilitation program is implemented during the first six months after surgery.
