FIGURE 3-112  Preoperative MRI. A: Coronal T2 image shows edema in posterosuperior humeral head consistent with small Hill-Sachs lesion. B: Axial T2 image suggests nondisplaced Bankart lesion.

Arthroscopic Findings: ■ A soft tissue Bankart lesion was identified and repaired along with capsular plication with four suture anchors (Fig. 3-114).

dislocation. Nondisplaced soft tissue Bankart lesion (Perthes lesion) is also seen (Fig. 3-112). ■ 3D CT scan shows a small Hill-Sachs lesion and no glenoid bone loss (Fig. 3-113).
