Researchers found an overall failure rate of 8% in patients with bony Bankart lesions who were treated with arthroscopic repair and reduction of the bony fragment, according to results of this study.
“Arthroscopic reduction and fixation of a bony Bankart lesion can achieve good results in selected cases. The size of the reconstructed glenoid is crucial to the success of the surgery,” Chun-Yang Jiang, MD, PhD, and colleagues wrote in the study abstract.
Jiang and colleagues prospectively analyzed 50 patients with recurrent anterior shoulder dislocation and bony Bankart lesions. The patients underwent arthroscopic reduction with internal fixation using suture anchors. The average age was 27.6 years and average follow-up was 32.5 months.
The researchers found significantly improved active forward elevation, but no significant differences in external or internal rotation, according to the abstract. The patients’ Rowe, Constant-Murley and American Shoulder and Elbow Surgeons scores significantly improved after arthroscopic reduction. However, three patients in the study had redislocations and one patient showed signs of positive anterior apprehension. At follow-up CT scans, researchers identified bony fragments in five patients. The researchers noted the reconstructed size of the glenoid was less than 80% in three cases of the failed cases and greater than 80% in one 1 of the failure cases.
