Arthroscopic release of the suprascapular nerve at the suprascapular notch, to our knowledge, has rarely been described. The purpose of this study was to evaluate the feasibility and relevant anatomic landmarks in a cadaveric model that can be identified arthroscopically for reliable and reproducible arthroscopic release of the superior transverse scapular(More)
Previous experimental studies of failure of rotator cuff repair have involved single pull to ultimate load. Such an experimental design does not represent the cyclic loading conditions experienced in vivo. We created 1 x 2 cm rotator cuff defects in 16 cadaver shoulders, repaired each defect with three Mitek-RC suture anchors (Mitek Surgical Products, Inc,(More)
Isolated posttraumatic subluxation of the extensor carpi ulnaris tendon at the wrist has received scant attention in the literature. Five patients with this condition were seen during a 21-month period. All had chronic subluxation resulting from forearm hypersupination injury sustained during an athletic activity. Surgical treatment was indicated for three(More)
Previous experimental studies of failure of rotator cuff repair have involved a single pull to ultimate load. Such an experimental design does not represent the cyclic loading conditions experienced in vivo. We created 1 cm x 2 cm rotator cuff defects in 16 cadaver shoulders, repaired each defect with transosseous simple sutures, and cyclically loaded the(More)
Increases security of fixation in rotator cuff repair is usually achieved by increasing the strength of fixation. Paradoxically, the problem can be approached by techniques that decrease the strain at the margins of the tear so that weaker fixation will still be adequate. Such techniques provide greater safety tolerances for the strength characteristics of(More)
We present an arthroscopic technique used to identify mid to distal subscapularis tendon disruptions. These tears can be easy to miss and require a thorough arthroscopic evaluation of the medial biceps sling and the medial side wall of the bicipital groove to detect. The arthroscopic procedure is performed with the patient in the lateral decubitus position,(More)
PURPOSE The purpose of this study was to evaluate the relation between the specific exit point of the screws securing the coracoid graft and the suprascapular nerve during the Latarjet procedure. METHODS Ten fresh-frozen shoulder specimens were dissected after having undergone an open Latarjet procedure. RESULTS The mean distance from the posterior exit(More)
PURPOSE Our purpose was to determine the relationship between number of preoperative shoulder dislocations and total dislocation time and the need to perform bone deficiency procedures at the time of primary anterior instability surgery. Our hypothesis was that need for bone deficiency procedures would increase with the total number and hours of(More)
Importance Recurrent tear after rotator cuff repair (RCR) is common. Conservative, and open and arthroscopic revisions, have been advocated to treat these failures. Aim or objective The purpose of this systematic review was to evaluate the different options for managing recurrent rotator cuff tears. Evidence review A search was conducted of level I through(More)
The technique of arthroscopic subscapularis repair continues to evolve. A three-sided subscapularis release (e.g. anterior, posterior, superior) is commonly advocated for improving tendon excursion to bone. However, a lateral release is commonly required as well, particularly for full thickness, upper subscapularis tears and full thickness, complete(More)
