Abstract：Objective To summarize mechanism, pathological features, clinical manifestation and diagnosis, and treatment of posterior shoulder dislocation complicated with massive rotator cuff tears. Methods We reported a patient with posterior shoulder dislocation complicated with massive rotator cuff tears who underwent arthroscopic surgery and had a good result. Pubmed, OVID, Springer, Science Direct, CNKI, Wanfang and VIP databases were searched for related arthicles published from January 1950 to February 2016. Results There were totally 7 cases of posterior shoulder dislocation complicated with massive rotator cuff tears, 6 of the cases were reported in 5 articles. The mean age was 35 years. All cases were caused by violence. Both supraspinatus and infraspinatus were injured in all cases. Subscapular muscle was injured in 4 out of 7 cases. Open injury was found in only one case and close injury in 6 cases. All patients underwent surgical treatments and had good outcomes. The patient reported in this article underwent arthroscopic surgery and also had good results. Conclusions Patients of posterior shoulder dislocation complicated with massive rotator cuff tears present various clinical manifestations and were difficult to diagnose. Violent injury is the most common cause. MRI is helpful for diagnosis. Surgical treatment is effective for this injury. Arthroscopic surgery is an ideal choice.
