Semi-shoulder arthroplasty for complicated proximal humerus fractures / 中国组织工程研究

ABSTRACT

BACKGROUND:Semi-shoulder or total shoulder arthroplasty for complicated proximal humerus fractures is better in the rapid elimination of pain and restoration of joint function. OBJECTIVE:To analyze the surgical techniques and clinical effects of semi-shoulder arthroplasty on the treatment of complicated proximal humerus fractures. METHODS:The surgical efficacy of 12 cases of complicated proximal humerus fractures who had al received semi-shoulder arthroplasty was analyzed. According to Neer classification, there were two cases of three-part fractures and 10 cases of four-part fractures. X-ray observation and Neer scoring criteria were also used to conduct a clinical evaluation of shoulder joint function after operation. RESULTS AND CONCLUSION:Al the patients were fol owed up for 18 months in average (6 to 48 months). Based on Neer scoring, excellent was in 10 cases, good in one case, fair in one case. The excellent rate was 92%. During the fol ow-up period, prosthesis location was good and there were no complications, such as periarticular fractures, nerve injury, infection, dislocation or looseness. Attention should be paid for the effective restoration of shoulder cuff and the correct reconstruction of the large and smal nodules in semi-shoulder arthroplasty. Besides, it also should be combined with the early and standard functional exercises. The clinical effect of semi-shoulder arthroplasty is satisfactory and it is an effective way to treat complicated proximal humerus fractures.
