Accuracy of magnetic resonance imaging in detecting biceps pathology in patients with rotator cuff disorders: comparison with arthroscopy.

Background: There is limited information on the validity of magnetic resonance imaging (MRI) in detection of biceps disease. The purpose of this study was to examine the measurement properties of noncontrasted MRI in diagnosis of biceps disease using arthroscopic surgery as the "gold standard."

Materials And Methods: Prospectively collected surgical data of patients with impingement syndrome or rotator cuff tear, with biceps disease (study group) or without biceps disease (control group), were reviewed.

Outcome of distal clavicle resection in patients with acromioclavicular joint osteoarthritis and full-thickness rotator cuff tear.

Purpose: The purpose of this study was to examine the impact of distal clavicle resection (DCR) on subjective and objective outcome measures in patients with acromioclavicular (AC) joint osteoarthritis (OA) and rotator cuff tear.

Methods: Prospectively collected data of consecutive patients with arthroscopic evidence of OA of the ACJ with complete data at 2 years were used for the data analysis. Patients with moderate-to-severe OA of the AC joint underwent a DCR in conjunction with rotator cuff repair, while patients with mild OA of the ACJ underwent surgery related to concomitant rotator cuff tear without a DCR.
