Key result
A revision arthroscopic technique using iliac crest autograft for failed anatomic glenoid reconstruction is described, facilitating easier identification of landmarks and accurate graft positioning.
Why the study?
Arthroscopic revision stabilization for failed anterior shoulder stabilization procedures is increasingly performed and technically challenging, prompting the description of a revision arthroscopic technique for failed arthroscopic anatomic glenoid reconstruction.
Describes a revision arthroscopic technique using iliac crest autograft for failed anatomic glenoid reconstruction, noting it is technically easier than revision after a Latarjet procedure.
AAGR with distal tibial allograft shows short-term promise; leaves open long-term durability versus Latarjet in glenoid bone loss.
Recurrent instability after anterior shoulder stabilization surgery is not an uncommon complication, with variable rates of recurrences associated with different surgical procedures. The Latarjet procedure continues to be the gold standard in the management of anterior instability with significant glenoid bone loss, although a recent trend toward arthroscopic anatomic glenoid reconstruction (AAGR) with distal tibial allograft has been noted, with excellent short-term results and minimal complication rates. Arthroscopic revision stabilization for failed stabilization procedures is increasingly being performed, although it is technically more challenging than the primary stabilization procedure because of the anatomic rearrangements of the index surgery. In this article, we describe a revision arthroscopic technique for anatomic glenoid reconstruction using iliac crest autograft for a previous failed AAGR procedure secondary to nonunion of the graft. The graft is passed through the Halifax far-medial portal without splitting the subscapularis. Arthroscopic revision in the setting of a failed AAGR procedure is technically easier than after a Latarjet procedure, as the anatomy is relatively undisturbed in the former, facilitating easier identification of anatomic landmarks, accurate graft positioning, and decreased risk of neurovascular injuries. A Bankart capsulolabral repair is performed after graft fixation, making the graft extra-articular and providing additional stability.
