ObjectiveTo investigate the operative method and clinical results of arthroscopic assisted treatment of shoulder dislocation combined with fracture of greater tuberosity of humerus.MethodsFrom 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.ResultsAll 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%.ConclusionFor 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.
