PURPOSE To evaluate the outcome of hemiarthroplasty with bone block graft and low profile prosthesis (Aequalis(R) fracture prosthesis) for the comminuted proximal humerus fractures. MATERIALS 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 degrees (90~170), external rotation at side was 45.5 degrees (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.

PURPOSE To evaluate the functional results after internal fixation with two low profile plates in fractures of the distal tibia. MATERIALS AND METHODS From March 1998 to October 2002, twelve patients with fractures of the distal tibia were treated with internal fixation using two low profile plates and followed for at least one year. Fractures according to AO/OTA classification were one Type A1, four Type A2, two Type C1, two Type C2 and three Type C3. We analyzed the functional results by the Olerud and Molander ankle scoring system and the postoperative complications. RESULTS The average functional score was 81.2 points and the results were three excellent, six good, one fair and two poor. Bony union was achieved in all cases. There was 1 case of superficial wound infection as a complication. CONCLUSION Internal fixation with two low profile plates in fractures of the distal tibia may minimize the incidence of soft tissue complications and provide good bony union and functional results. Therefore, we consider internal fixation with two low profile plates as a good alternative treatment of the distal tibial fracture.
