Arthroscopic Coracoid Bone Block for Posterior Glenohumeral Instability: Description of Surgical Technique and a Case Report

This case report describes the surgical technique of posterior arthroscopic bone block using the coracoid graft to treat recurrent posterior dislocations and describes preliminary results. Performance of coracoid transfer as a graft for posterior arthroscopic bone block i n one patient (two shoulders) with recurrent posterior glenohumeral instability refractory to clinical treatment for six months, excluding volition dislocation. The patient was followed up weekly for the first three weeks when the stitches were removed. Postoperative computed tomography was performed before the patient was authorized to practice contact and aquatic sports (۳–۴ months after surgery). Patient returned to previous activities without complaints or limitations. There were no neurovascular compli cations. The initial results using coracoid as a bone graft for posterior instability were positive, and the technique requires reproduction to investigate possible complications. To date, no study has been found in the literature that reports an open or arthroscopic coracoid bone block technique.  Level of evidence: V
