Abstract:
OBJECTIVESTo evaluate the clinical results of hemiarthroplasty in the treatment of severe proximal humeral fracture, and to analyze the influencing factors.
METHODSForty-two cases with mean age of 63 years old were included. Mean follow-up duration was 29 months (12 - 48 months). Subjective satisfaction, ROM, muscle strength, stability, smoothness of motion were all evaluated. Radiographs of anterio-posterior view and axial view of shoulder were taken. Total-length radiographs of bilateral humerus were taken for 27 cases and CT for 15 cases.
RESULTSWith Constant-Murley score 19 cases (45%) were excellent, 17 cases (40%) good, 6 cases (15%) poor, and the rate of total satisfactory was 85%. Post-operative active ROM, anterior flexion was (100 +/- 32) degrees , external rotation (16 +/- 11) degrees , external rotation and posterior extension to the level of L2.
CONCLUSIONSThe reasons for the poor results include improper restoration of humeral length, over retroversion of prosthesis, poor fixation of tuberosity, malunion, absorption of greater tuberosity and heterotopic ossification.
