Arthroscopic Decompression and Subsequent Bone-Grafting of Spinoglenoid Cyst.

Abstract

Spinoglenoid cysts are associated with labral tears; however, little is known about their associated bony pathology. This Technical Note describes an arthroscopic technique to decompress and subsequently graft a spinoglenoid cyst and associated bony defect. Appropriate preoperative imaging is key to understanding the location of the bony defect and therefore crucial to the success of the bone graft. Adequate release of the labrum should be performed to fully visualized the bony lesion. A subchondroplasty cannulated drill is then placed in the bony defect under direct visualization and said defect is then filled with calcium phosphate cement. Care is taken to ensure no cement is allowed to extrude into the shoulder joint. After the cement has cured, labral pathology is repaired and the usual postoperative physiotherapy protocol is initiated.
