Arthroscopic shoulder stabilization using Mitek anchors.
The purpose of this paper is to report our experience with an arthroscopic stabilization technique using bone anchors in the treatment of chronic unidirectional anterior-inferior shoulder instability. 30 of 32 patients (average age, 26 years) were followed for an average of 24 months (range 12 to 36). There were 28 patients with dislocations and four with subluxations. In the group of the dislocators five patients had more than 10 dislocations and 15 patients between one and seven (average three). In 68% a sport injury was the reason for the first dislocation. Due to the length of the labroligamentous detachment two to four anchors were used for stabilization. According to the criteria of Rowe, in the group of the subluxators (4) two had an excellent and two a good result. In the group of the dislocators (26) two patients dislocated their shoulder again after reconstruction without a new accident, one had a recurrent dislocation from significant trauma. Two of them had an open stabilization afterwards. Overall there were 53.9% excellent, 34.6% good and 11.5% poor results. In 50% there was no restriction of shoulder motion, 21% had a loss of external rotation of 5 degrees and 29% of 10 degrees. Arthroscopic shoulder stabilization with help of Mitek anchors seems to be a good method for treatment of chronic unidirectional anterior-inferior instabilities with less than 10 dislocations preoperatively. All patients, who suffered a spontaneous recurrent dislocation, had more than 10 dislocations before. In these cases this arthroscopic procedure is not suited to restore stability, even if a Bankart-lesion is present.
