Pearls and Pitfalls

Pearls

•Horizontal posterior approach for better placement of the drill guide

•A harvest location 4 to 5 cm lateral to the medial scapular border to obtain the largest cross-sectional graft

•Expansion of the anterior interval approach using index finger for easier graft passage through the rotator interval

Pitfalls

•Drill guide malpositioning can lead to tunnel malalignment and graft malpositioning

•Acromion base fracture due to improper harvest location too far lateral on the spina scapulae

•Suture cut-through of the graft in patients with poor bone quality
