Magnetic resonance imagingarthrogram images of the left shoulder before treatment: (a) The axial view: Red arrow -the medial dislocation of the long head of the biceps tendon and the yellow arrow -an intact subscapularis; panes (b and c) display the coronal and sagittal views, respectively, that the integrity of the supraspinatus (green arrows) and subscapularis (yellow arrow) wascompletely intact.

Magnetic resonance (MR) arthrogram and MR imaging (MRI) of the left shoulder joint were indicated medial dislocation of the LHBT with intact subscapularis and supraspinatus tendons (Fig. 1).
Intraoperative scope image reveals the patulous consistency of the posterior capsule. Posteriorlabrum appears to be intact.

The posterior capsule was patulous, consistent with pre-operative imaging findings (Fig. 2).
Intraoperative images of (a) sutures used for the capsulorrhaphy and (b) reduction of the glenoid cavity volume by the capsulorrhaphy in the 6:30-11:30 region(HH - Humeral head).

Three stitches were used in a pinch and tuck technique starting at the 6:30 position on the glenoid and progressing clockwise in a circumferential manner to the 11:30 region on the glenoid cavity, and the volume of the cavity was reduced (Fig. 3).
Intraoperative image illustrates the integrity of the biceps insertion to be intact with the biceps tendon being medially dislocated from the bicipital groove(HH - Humeralhead, LHBT - Long head of the biceps tendon, SSC - Subscapularis, and MGHL - Medial glenohumeral ligament).

The integrity of the subscapularis tendon was intact with a medially dislocated LHBT (Fig. 4).
