During this minimally-invasive procedure, the surgeon removes the end of the clavicle at the acromioclavicular joint in the shoulder. Removing this portion of bone will decompress the joint. It will help relieve the pain and loss of motion caused by arthritis or impingement.
Distal clavicle excision, also called distal clavicle resection or the Mumford procedure, is a minimally invasive procedure aimed at alleviating persistent pain caused by shoulder impingement or arthritis.
Pathology of the acromioclavicular joint is common and often resistant to conservative treatment, requiring distal clavicle excision for definitive relief. First described as an open technique by Mumford and Gurd in 1941, distal clavicle excision has evolved greatly, with arthroscopic techniques currently predominating.
Open distal clavicle resection may be performed expeditiously and at low cost through a cosmetically acceptable small saber-type incision, often in less time than it takes to set up arthroscopic equipment.
Distal clavicle resection (DCR), also known as the “Mumford procedure,” is a surgical technique commonly used to address various conditions related to the shoulder joints, particularly those involving the acromioclavicular (AC) joint (joint of the shoulder where two bones meet).
Overview. This minimally-invasive procedure helps to relieve pain and loss of motion in the shoulder from arthritis or impingement. During the procedure the end of the clavicle closest to the acromion in the shoulder is removed to allow pain-free movement of the joint. Preparation.
Impingement syndrome and associated rotator cuff tears are common shoulder problems. This condition is caused when the rotator cuff tendons rub the underside of the acromion. The resulting damage can be repaired using minimally invasive techniques.
Most patients with an acromioplasty or distal clavicle excision should be able to do pendulum exercises as shown in the hospital and may be asked to demonstrate these in the office.
What is a distal clavicle excision? A distal clavicle excision is when the tip of the clavicle is burred down to widen the AC joint from arthritis. Typically the AC joint moves and does not make contact but when osteoarthritis is severe there is excessive contact between the acromion and clavicle.
This Technical Note and accompanying video describe an indirect subacromial arthroscopic distal clavicle excision using a fluoroscopic Kirschner wire guide placed at the proximal border prior to resection to serve as a visual and mechanical reference to overexcision.
