Use of posteroanterior reference guides for bone block or coracoid process transfer in anterior glenohumeral instability: a cadaveric study of the relationship to the suprascapular nerve

The use of posteroanterior reference guides for suture button fixation was not associated with iatrogenic suprascapular nerve injury in the specimens examined. However, the proximity of the suprascapular nerve underscores the need for caution. Comparative analysis with anteroposterior bone block techniques is required to establish the potential benefits of this procedure. Level of evidence: V.
