It is a retrospective study on outcomes of one-stage arthroscopic treatment of posterior shoulder dislocation complicated with rotator cuff tears



Posterior shoulder dislocation is considered to be a rare injury accounting for only 2-5% of all shoulder dislocations. Despite its scarce appearance in daily clinical practice, posterior shoulder dislocation is of significant diagnostic and therapeutic interest because of its damage on shoulder function and its high incidence of missed initial diagnosis. Posterior shoulder dislocation associated with rotator cuff tears is more rare and results in more loss of shoulder function. The rotator cuff plays a significant role in the static and dynamic stability of the glenohumeral joint. Rotator cuff tears may occur after shoulder dislocations and make more damage on shoulder stability. It is still a challenge for surgeons to treat shoulder dislocations complicated with rotator cuff tears.
Subjects and Methods:
We retrospectively reviewed 6 patients who got a posterior shoulder dislocation complicated with rotator cuff tears and were treated in our institution. There were 4 males and 2 females, with an average age of 57.1 years (44-69). Three left shoulders and three right ones were involved. All six patients underwent an arthroscopic suture repair of the posterior labrum-ligament-capsular complex (reverse Bankart repairing) with rotator cuff repair. All operations were performed by one same surgeon. All patients were reviewed in the clinic. The shoulder Constant-Murley score, visual analogue scale (VAS) for pain and the Oxford Shoulder Instability Score were evaluated before and after surgery.


The mean follow-up time was 21.7 months. At the follow-up ending time, there was no patient who got recurrence dislocation. At 18 months after surgery, the VAS for pain significantly decreased from 4.3±1.7 before surgery to 0.8±0.3 after surgery(P=0.014). The shoulder Constant-Murley score significantly from 43.2±5.6 before surgery to 88.0±11.5 after surgery(P<0.001). The Oxford score significantly improved from 37.8±5.0 before surgery to 13.5±2.3 after surgery(P<0.001). The exterior rotation at 0° abduction of the injuried shoulder was 30.8±8.6°, which was significantly lower than 41.2±4.4° of the contralateral one(P=0.002).


Arthroscopic reverse Bankart repairing with one-stage rotator cuff repairing is effective to treat posterior shoulder dislocations complicated with rotator cuff tear.
