Arthroscopic Subacromial Decompression (ASD) & Arthroscopic ACJ Excision (ACJ)



The anterior spur on the Acromion is shaved away with an arthroscopic burr through two small 5mm incisions (posterior & lateral). The ACJ is excised by putting the burr through an additional anterior 5mm incision. No sutures are used for closure and a sling is applied for comfort only. Movement commences as soon as the patient is comfortable (2 days post-op).
