Arthroscopic Mumford procedure variation of technique.

Fifty-seven patients had arthroscopic Mumford procedures for acromioclavicular pain non-responsive to conservative treatment. Thirty-nine of these patients had concomitant rotator cuff repairs. All had significant improvement of their distal clavicular pain. Neither the amount nor the completeness of distal clavicle resection affected the results. Arthroscopic distal clavicle resection is a safe and effective method of alleviating acromioclavicular pain.
