Purpose: To evaluate the outcome of hemiarthroplasty with bone block graft and low profile prosthesis (Aequalisⓡ fracture prosthesis) for the comminuted proximal humerus fractures.
Material and Methods : Sixteen low profile prostheses were used since July 2004, and 11 patients were followed-up for average 19.9 (12∼30) months. Their mean age was 67.3 (52∼78) years. Pain and satisfaction visual analog scale (VAS), range of motion, and modified UCLA score for hemiarthroplasty were evaluated at every visit. Radiography was also checked for stem position, loosening, and tuberosity union.
Results: Mean pain VAS was 2.7 (0∼5), and mean satisfaction VAS was 8.4 (5∼10). Mean active forward flexion was 137˚ (90∼170), external rotation at side was 45.5˚ (25∼70), and internal rotation at back was T10 (T7∼L1). Modified UCLA score was 19 (12∼30) at final visit. All stems were stable, and there were no loosening at the final follow-up. All tuberosities were united except two tuberosity absorptions.
Conclusion: The outcome of hemiarthroplasty with bone block graft and low profile prosthesis was comparable to other implants for comminuted proximal humerus fractures. This system had unique advantages for tuberosity union. Further study with more patients and longer follow-up are necessary to clarify the effectiveness of this prosthesis.
