Ellman reports the first 50 consecutive cases of arthroscopic subacromial decompression for chronic impingement refractory to conservative care. Patients were graded on the UCLA Shoulder Rating Scale at 1 to 3 year follow-up. The study asks whether an arthroscopic acromioplasty can match the open procedure while sparing the deltoid.
When impingement fails 6+ months of conservative care, ASD offers open-acromioplasty results without detaching the deltoid, so patients return to daily activities within days. The key teaching point is that a satisfactory result depends on completeness, not the approach. Two failures here came from a retained coracoacromial ligament remnant and an unresected anterolateral acromion.
Watch what the outcomes tell you: pain and function improve, but strength does not. That is why cuff-tear patients never reached excellent, and why you counsel them that decompression relieves pain, not weakness.
Diagnosis matters as much as technique. Confirm impingement with a subacromial lidocaine injection, and use the shoulder drawer sign to exclude occult instability, because ASD fails when instability is the true driver. Salvage after failed prior shoulder surgery is discouraging, with nearly half unsatisfactory.
