Fig 1 (A) Coronal-view computed tomography scan and (B) 3-dimensional reconstruction of posterosuperolateral aspect of humeral head depicting a 2.0 × 1.7 (anteroposterior) × 1.0 cm (depth) Hill-Sachs impaction deformity covering approximately 23% of humeral head articular surface. There was minimal flattening along the anterior margin of the glenoid with evidence of approximately 5% glenoid bone loss (not shown).

Fig 3 Arthroscopic view of final reconstruction. Allograft plugs are press fit into the defect and seated within the prepared socket to achieve a “snowman” appearance. Two allograft plugs measuring 10 mm and 6 mm in diameter were transplanted.
