Implantation of plate and hollow screw for the repair of the split fracture of greater tuberosity of humerus:comparison of shoulder joint function / 中国组织工程研究

ABSTRACT

BACKGROUND:Canada Montreal Scholar Mutch et al have recently proposed a new morphologic classification of fracture of greater tuberosity of humerus. They divided these fractures into three typeavulsion, split and depression. OBJECTIVE:To compare the recovery of shoulder function after conventional plate-screw and hol ow-screw fixation for the repair of the split fracture of greater tuberosity of humerus. METHODPatients with greater tuberosity of humerus, who were treated in the Department of Orthopedics of Yichang Yiling Hospital, China from January 2010 to January 2014, were classified according to Mutch’s classification. A total of 83 patients with split greater tuberosity of humerus after complete fol ow-up were retrospectively analyzed. Of them, 23 cases received plate-screw fixation as plate-screw group, and 60 cases received hol ow-screw fixation as hol ow-screw group. Visual Analog Scale, the United States Scores of Shoulder and Elbow Surgeons, and Constant and Murley Scoring Systems were utilized to assess the therapeutic outcomes. Patient’s pain and changes in shoulder function were analyzed before and after treatment. RESULTS AND CONCLUSION:A total of 83 patients were fol owed up. Fixator was obtained at 1 year after surgery in al patients. No significant difference in Visual Analog Scale, the United States Scores of Shoulder and Elbow Surgeons, and Constant and Murley Scoring Systems was detected in both groups before treatment (P>0.05). Significant differences in Visual Analog Scale, the United States Scores of Shoulder and Elbow Surgeons, and Constant and Murley Scoring Systems were detectable in both groups at 16 months after removal of the fixator (P<0.05). Data were better in the hol ow-screw group than in the plate-screw group. Above results suggested that hol ow-screw fixation in the repair of split fracture of greater tuberosite of humerus is simple to be operated, with smal trauma, and is an ideal fixation method. Clinical repair effect is better than plate-screw fixation.
