Open and arthroscopic posterior bone block with iliac crest autograft for posterior shoulder instability – systematic review of clinical and radiological outcomes

Arthroscopic Posterior Bone Block Stabilization Using a Tricortical Autograft of the Ipsilateral Scapular Spine

“…A spectrum of recurrent instability rates follow these procedures, with arthroscopic studies reporting rates ranging from 0% to 12.5% and open studies reporting rates ranging from 0% to 36.4%. 8 The authors of the quoted article could also find more evidence of functional improvements with arthroscopic procedures than with open approaches. This variability suggests that the choice of surgical technique may impact the risk of recurrent instability, indicating a favorable outcome after arthroscopic surgery, as used in our technique.…”

“…Furthermore, it is crucial to acknowledge the concerns raised regarding hardware complications, which were observed in a substantial portion of patients after ICBG procedures with screw fixation. 8 , 9 Specifically, the prominence of screws within the (partially resorbed) graft can be encountered in up to 67% of patients, which puts the infraspinatus tendon at risk and often requires hardware removal. 8 , 10 , 11 In accordance with this, Camenzind et al.…”
