Abstract:

 Objective    To compare the recovery of shoulder function after conventional self-made claw-shaped press plate and hollow-screw fixation for repair of the split fracture of greater tuberosity of humerus.　Mehtods　A prospective randomized controlled study was performed in 32 patients with split fracture of greater tuberosity of humerus who were assigned into 2 groups from January 2014 to January 2016. Group A (n=16) received treatment using self-made claw-shaped press plate and group B(n=16) received treatment using hollow-screw fixation. The fracture healing time ,VAS scores, the United States Scores of Shoulder, Elbow Surgeons and Constant and Murley Scoring Systems were utilized to assess the therapeutic outcomes.  Results　The mean follow-up period was 21.2 months. Group A (n=16) was better than group B (n=16) in the United States Scores of Shoulder and Elbow Surgeons and Constant and Murley Scoring Systems(P<0.05). There was no significant differences in the VAS scores and fracture healing time (P>0.05).  Conclusion    The study suggests that self-made claw-shaped press plate in the repair of split fracture of greater tuberosite of humerus is an ideal fixation method with allowance for the early functional exercise.
