Radiographs were judged to be normal (Fig. 1).
Magnetic resonance imaging showing an isolated teres minor (TM) myotendinous lesion. (a) Axial view, T2 (distal): Myotendinous tear of TM, (b) Sagittal view, T2: Isolated tear of TM. (c) Coronal view T2: No lesion of the supraspinatus. (d) Axial view, T2 (proximal): No lesion of infraspinatus or subscapularis. (e) Sagittal view, T1 (Y view): No atrophy of the muscles, no fatty infiltration.

TM at the myotendinous junction without any other associated lesions (Fig. 2).
Arthro-computed tomography scan showing no capsular lesion. (a) Axial view: Intact articular capsule (arrow: No contrast dye throughout the joint). (b) Coronal view: Intact inferior articular capsule and supraspinatus.

An arthro-computed tomography scan was consecutively performed and did not reveal any contrast dye moving throughout the joint, thus confirming the integrity of the articular capsule and comparable to what has been described in the case of IS myotendinous ruptures (Fig. 3).
Intraoperative view, before the repair, showing the teres minor (TM)myotendinous tear, and the integrity of the infraspinatus. TM = Teres Minor, IS = Infraspinatus.

TM was confirmed, as well as the integrity of the IS (Fig. 4). There was no opening of the joint and the articular capsule was not torn.
Intraoperative view after the repair. TM = Teres Minor. IS = Infraspinatus. Green sutures = Side-to-side suture of the TM. Blue sutures = Lateral sutures with IS.

We completed the repair by placing three lateral sutures between the TM and IS to close the interval between the two muscles (Fig. 5).
Magnetic resonance imaging performed 6 months after the surgery. (a) Axial view, T2 (same slice as preoperative imaging): Healing of the Teres minor (TM). (b) Sagittal view, T2: Healing of the TM. (c) Sagittal view, T1 (Y view): No muscle atrophy, no fatty infiltration.

An MRI was done at this follow-up and showed a complete healing of the muscle without any atrophy or fatty infiltration (Fig. 6).
