Treatment of Irreducible Traumatic Anterior Shoulder Dislocation Caused by Subscapularis Tendon Interposition.

Irreducible shoulder dislocation is an uncommon event. When it does occur, blocks to reduction can include bone, labrum, rotator cuff musculature, or tendon. Concomitant rotator cuff tear at the time of initial dislocation is not an exclusive complication of anterior shoulder dislocation in the older population. Indeed, rotator cuff tear should not be excluded based solely on the patient's age. Rotator cuff interposition is not an uncommon complication after anterior dislocation of the shoulder. It should be suspected when there is incongruency of the joint and persistent subluxation on postreduction radiographs. If such incongruence or subluxation is seen, a computed tomographic (CT) or magnetic resonance imaging (MRI) scan must then be obtained to determine the nature of the interposed soft tissues. The key to treatment is early diagnosis and adequate imaging. Open reduction and repair of the rotator cuff should be performed. We present a technique for treating irreducible anterior shoulder dislocation caused by interposition of the subscapularis tendon. Both CT and MRI observations, along with intraoperative findings and surgical technique, are discussed.

Arthroscopic Reduction and Fixation of Tibial Spine Avulsion Fractures by a Stainless Steel Wiring Technique.

Several techniques of arthroscopic treatment of tibial spine avulsion fractures have been described in the literature. These techniques include the use of various fixation devices such as screws, K-wires, wiring, sutures, and suture anchors. In this study, we evaluate a new wiring technique for the treatment of these injuries. This technique involves fixation by stainless steel tension wires passed over the fractured spine and tied over a bone bridge. The advantages of this technique are that it aids in reduction, allows for compression of the tibial spine fragment anatomically in its fracture bed, provides stable fixation in difficult comminuted fractures, and allows for early mobilization and weight bearing because of the solid fixation.

A Shortcut to Arthroscopic Suprascapular Nerve Decompression at the Suprascapular Notch: Arthroscopic Landmarks and Surgical Technique.

Arthroscopic suprascapular nerve decompression at the suprascapular notch is a technically demanding surgical procedure with a steep learning curve. The aim of this Technical Note is to describe important pearls for an arthroscopic decompression of the suprascapular nerve relying on the palpation of the coracoclavicular ligaments before starting the arthroscopic visualization. This reduces the time and minimizes the resection of the surrounding fat.
