Latarjet Operation for Anterior Shoulder Instability with Glenoid Bone Defect

Purpose:We wanted to evaluate the clinical results of the Latarjet procedure for treating anterior shoulder instability combined with a glenoid bone defect.: Between Oct. 2006 and May.2007, fourteen patients underwent a Latarjet operation to treat their anterior shoulder instability combined with a glenoid bone defect.The mean follow-up period was 15 months (range: 12 to 19 months), and the average age at the time of surgery was 29.9-years-old (range: 19 to 44 years).There were 13 males and 1 female.Eight patients exhibited involvement of the right shoulder.The dominant arm was involved in 8 patients.Six patients had undergone a previous arthroscopic Bankart repair before their Latarjet operation and 2 patients had a history of seizure. Materials and Methods Results:The average Rowe score improved from 51.8 to 80.2 with 9 excellent, 4 good, and 1 fair results.The average Korean shoulder score for instability improved from 61.6 to 82.1 postoperatively.The active forward flexion and external rotation at the side of the involved shoulder was an average of 8°and 16°l ess than that of the uninvolved shoulder.The muscle strength of the involved shoulder measured 78.7% in forward flexion and 82.5% in external rotation, as compared with that of the uninvolved shoulder.There was 1 case of dislocation, 1 transient subluxation, 2 fibrotic unions, 1 resorption of the transferred coracoid process, 1 intraoperative broken bone, 1 transient musculocutaneous nerve injury and 1 case of stiffness.
