| Abstract |
Purpose
: To evaluate functional results and study factors influencing results after humeral hemiarthroplasty for comminuted fractures of the proximal humerus. Materials and Methods : We reviewed 12 patients with average follow-up period of 23 months(12 to 42). The proximal humeral fractures consisted of one anatomical neck fracture, five three-part and six four-part fractures or fracture-dislocations. Constant score and Compito et al’ evaluation system were used for clinical assessment. Statistical analysis was done with the Wilcoxon test. Results : Six cases of anatomical neck, three-part fractures or fracture-dislocations showed 61 points on the average Constant score and three unsatisfactory results on the Compito et al’ evaluation ; Six of four-part fractures or fracture-dislocations showed 51 points and three unsatisfactory results. There were 59(two unsatisfactory) for five non-associated dislocation and 53(four unsatistactory) for seven associated dislocation ; 66(one unsatisfactory) for three under 60 years and 41(five unsatisfactory) for nine over 60 years ; 67(two unsatisfactory) for seven tuberosity union and 41(four unsatisfactory) for five tuberosity non-union or resorption ; 58(four unsatisfactory) for ten early operation within two weeks and 43(all unsatisfactory) for two delayed operation ; and 18(unsatisfactory) for one case of a accompanied rotator cuff tear. Conclusion : We concluded that tuberosity union was important factor influencing the results. Also, we thought that age, timing of operation and accompanied rotator cuff tear could be influenced to results. |
