CHAPTER 3 | Instability

FIGURE 3-27  Left shoulder viewed from an anterosuperolateral portal shows an inverted pear glenoid. G, glenoid; H, humeral head.

FIGURE 3-25  En face view of the glenoid on 3D CT scan shows 30% loss of inferior glenoid diameter in comparison with the opposite (normal) side. ■ At 2 weeks postinjury, he went to an orthopaedic sur- geon who x-rayed the left shoulder and found that the patient had a locked anterior dislocation. We first saw him at 3 weeks postinjury.

Physical Exam: ■ Subjectively, the patient complains of some mild tin- gling in digits 1, 2, and 3 of the left hand. However, two-point discrimination is normal. Sensory and motor examinations are otherwise normal. ■ Brachial and radial pulses are normal.

FIGURE 3-26  Type II SLAP lesion was repaired with LabralTape (Arthrex, Inc., Naples, FL) and a knotless BioComposite PushLock anchor (Arthrex, Inc., Naples, FL). BT, biceps tendon; G, glenoid.

FIGURE 3-28  Anterosuperolateral viewing portal shows the Hill-Sachs lesion engaging the anterior glenoid with combined abduction and external rotation. G, glenoid; HSL, Hill-Sachs lesion.
