Acromioclavicular Separations: Complications and How to Avoid Them.

Management of acromioclavicular separations remains controversial. A variety of surgical techniques have been described, but no clear consensus has formed regarding optimal treatment. As these techniques have evolved, so have the complication profiles.

The posterolateral portal: optimizing anchor placement and labral repair at the inferior glenoid.

The Bankart lesion is considered the critical lesion in anterior shoulder instability, in which the anteroinferior glenoid labrum separates from the glenoid rim. Technical advances in arthroscopy have ushered in a shift from open to arthroscopic Bankart repair. When one is performing an arthroscopic Bankart repair, proper portal placement is critical for success in labral preparation and anchor placement.

An assessment of the quality of rotator cuff randomized controlled trials: utilizing the Jadad score and CONSORT criteria.

Background: The AAOS's Clinical Practice Guideline on "Optimizing Care of Rotator Cuff Problems" suggested a lack of high-quality data. Our purpose is to quantify the quality of randomized controlled trials of rotator cuff disorders via the Jadad score, and to apply the 2010 Consolidated Standards of Reporting Trials CONSORT Criteria to determine factors associated with high Jadad scores and areas for improvement.

Methods: A systematic review using PRISMA guidelines was performed.

Muscle geometry affects accuracy of forearm volume determination by magnetic resonance imaging (MRI).

Upper extremity musculoskeletal modeling is becoming increasingly sophisticated, creating a growing need for subject-specific muscle size parameters. One method for determining subject-specific muscle volume is magnetic resonance imaging (MRI). The purpose of this study was to determine the validity of MRI-derived muscle volumes in the human forearm across a variety of muscle sizes and shapes.
