Indirect Arthroscopic Distal Clavicle Resection: an Institutional Experience with Midterm Functional Outcome

Acromioclavicular joint arthritis is a relatively common source of shoulder pain. The treatment options consist of conservative management and operative intervention depending on the severity and duration of the disease. Distal clavicle excision is the standard operative treatment and can be performed through either open or arthroscopic techniques. The purpose of this study was to evaluate the functional outcome of arthroscopic resection of the distal clavicle.

This was a prospective study, conducted in a group of 50 patients in the Post-Gra-duate Department of Orthopaedics, Govt. Medical College Srinagar, from July 2015 to July 2019 with cases followed for a minimum of 3 years.

The mean UCLA score improved from 13.2 preoperatively to 29.56 at final follow-up. An excellent result was seen in 10 patients (20%), good in 34 (68%), fair in 3 (6%) and poor in 3 (6%) patients. Overall 88% of the patients achieved excellent or good results and 94% were satisfied. Persistent pain and excessive intraoperative bleeding were the most common complications in our study.

1. Distal clavicle excision through an indirect or subacromial approach is a safe and effective procedure with very few complications. 2. The subacromial approach gives the added advantage of evaluating any glenohumeral joint and subacromial pathology. 3. This procedure is associated with less pain and improved cosmesis in comparison to open procedures.
