OBJECTIVE: To investigate the operative method and clinical results of arthroscopic assisted treatment of shoulder dislocation combined with fracture of greater tuberosity of humerus. METHODS: From February 2006 to June 2008, 12 cases of shoulder dislocation (6 left, 6 right) combined with greater tuberosity fractures were treated. There were 4 males and 8 females with an average of 58.5 years (range 34-79 years). Eleven cases fall down and one was crushed. The time from injury to hospital averaged 2.1 hours (range 30 minutes-24 hours). X-ray films revealed greater tuberosity fractures with average 5.8 mm (range 5-12 mm) displacement, and MRI showed Bankart lesion in 2 cases. Arthroscopic examination taken 3-14 days after reduction revealed 3 cases of Bankart lesion and 1 case of SLAP lesion. Three cases of great tuberosity fractures were fixed with cannulated screws, 2 cases with absorbable screws, 7 cases with titanium suture anchor. Three cases were repaired under arthroscopy, and 9 cases were repaired under arthroscopic assistance mini-incision. RESULTS: All the incisions were healed at first intention without infection. All patients were followed up for 6-32 months (average 16 months). The shoulder joints were fixed stably without redislocation. Six months after operation, there were 3 cases with mild limitation of abduction and 1 case with pain in flexion related with impingement. The X-ray films showed all fractures healed 2-6 months after operation (average 3.2 months). The American Shoulder and Elbow Surgeons and University of California at Los Angeles scores were 16.03 +/- 1.03 and 32.65 +/- 4.83, respectively. Eight cases were excellent, 3 were good, 1 were fair and the excellent and good rate was 91.7%. CONCLUSION: For shoulder dislocation combined with fracture of greater tuberosity of humerus, the treatment by shoulder arthroscopy is a safe and mini-invasive operative method with comprehensively accurate intraoperative diagnosis, satisfying therapeutic effect, good functional recovery, as well as obvious relief of pain.
