ABSTRACT

Objective To evaluate retrospectively the hemiarthroplasty in the treatment of severe comminuted intraarticular fractures of the proximal humerus.Method Thirty one patients suffered from severe comminuted intraarticular fractures of the proximal humerus were treated with shoulder hemiarthroplasty through Thompson approach from March 2000 to October 2004.The results were graded into the excellent,the good,the fair and the poor according to the scoring system-modification for hemiarthroplasty(SSMH) of Los Angeles California,USA(UCLA) basing on shoulder paining,functional status muscle strength and range of motion.Rusults The average operative time cost 65 minutes(ranged from 40 to 90 minutes),average amount of bleeding during operation were 280 ml(ranged from 200 to 350 ml).The patients exercised early postoperatively.After an average duration of 14.1 months of follow-up(ranging from 5 to 42 months),there were no infection and/or nerve damage occurred postoperatively,and the position of the prosthesis was confirmed to be excellent,moreover no lessening prosthesis,prosthesis dislocation,and/or prosthesis milieu fractures occurred radiographically.The outcomes of the treatment were excellent in 13,good in 14,fair in 3 and poor in 1 out of the 31 cases. The rate of both the excellent and the good were 87.10%.Conclusion Shoulder hemiarthroplasty is a preferable technique in the treatment of severe comminuted intraarticular fractures of the proximal humerus.
