Arthroscopic suture bridge rotator cuff repair: functional outcome, repair integrity, and preoperative factors related to postoperative outcome.

Objectives: To assess the retear rate, retear size and location, the clinical impact of a retear, and preoperative patient factors related to postoperative outcome after arthroscopic suture bridge rotator cuff repair.

Methods: Fifty six patients with an isolated, full-thickness supraspinatus tendon tear who underwent arthroscopic suture bridge rotator cuff repair were retrospectively identified. Patients were evaluated and rotator cuff integrity was assessed using ultrasonography.

Clavicle-induced narrowing of the thoracic outlet during shoulder abduction as imaged by computed tomographic angiography and enhanced by three-dimensional reformation.

Objective: This study aimed to confirm the location and degree of compromise of the subclavian vessels within the thoracic outlet during ipsilateral arm abduction in patients with clinical evidence of thoracic outlet syndrome and to identify both the physical and physiologic source of neurovascular compromise that induces the symptoms of thoracic outlet syndrome.

Design: After a neuromuscular and vascular examination, all of the subjects underwent a two-part high-resolution computed tomographic angiography with three-dimensional reformation. The initial study was performed with the arm held at the side in an anatomical neutral position.
