Right Open Acromioplasty, Distal Claviculectomy, and Partial Bursectomy

SKU: S15a02017

This exhibit depicts the anterior anatomy of the shoulder with acromioclavicular spurring, bursal impingement, and subsequent decompression. Anatomical structures include: the clavicle, acromion, subacromial bursa, supraspinatus, biceps brachii, coracoid process, and the humerus. During abduction, the supraspinatus contracts to raise the arm, and the subacromial bursa glides beneath the acromioclavicular joint to prevent friction. Degenerative bone spurs on the inferior acromion cause narrowing of the subacromial space. The increased friction pinches the subacromial tissues resulting in inflammation, pain, and weakness of the shoulder joint. An incision is made over the acromion process and a partial bursectomy is carried out. Further decompression is accomplished by smoothing the acromion into a type one (flat) configuration and resecting the distal end of the clavicle.
