Mobilization Techniques for Acute and Chronic Retracted Pectoralis Major Tears for Primary Repair
Surgical Technique The senior author (M-E.L.) developed extensive expertise in chronic PM repairs in an academic tertiary setting. In PM ruptures surgically treated around 10 to 12 weeks from injury, a useful layer of scar tissue forms along the torn tissue edge that is consistently reliable to hold sutures without requiring grafting once extensive tissue mobilization is completed. An allograft is considered if there is a residual gap after mobilization or in revision repairs.

An in vitro study of glenoid implant peripheral peg interface mechanics during eccentric loading and lift‐off
1 INTRODUCTION In anatomic total shoulder arthroplasty, the glenoid component is critical as aseptic glenoid loosening remains one of the most common reasons for failure.1, 2 The rocking horse mechanism, whereby cyclic eccentric glenoid loading drives progressive failure of the cement mantle, is thought to be the cause of glenoid loosening in the absence of any other pathological mechanism.3-5 As the resultant joint forces progress from the inferior to the superior glenoid edge in vivo, the...

Interpreting Electrodiagnostic Studies for the Management of Nerve Injury
Nerve injuries are common after trauma and can be life-altering for patients. Electrodiagnostic studies are the gold standard for diagnosing and prognosticating nerve injuries. However, most surgeons are not trained in the interpretation of these studies; rather, they rely on the interpretation provided by the electrodiagnostician, who in turn is unlikely to be trained in nerve reconstruction.

The Effect of Flexor Digitorum Profundus Repair Position Relative to Camper Chiasm on Tendon Biomechanics
Purpose The purpose of this study was to investigate the impact of repairing a zone II flexor digitorum profundus (FDP) laceration anatomically versus extra-anatomically on tendon loads and work of flexion (WOF). Methods Twenty digits from 5 cadaveric specimens were tested using an in vitro active finger motion simulator under 2 FDP tendon repair conditions: anatomic and extra-anatomic.
Does the Walch type B shoulder have a transverse force couple imbalance? A volumetric analysis of segmented rotator cuff muscles in osteoarthritic shoulders
Background The etiology of the Walch type B shoulder remains unclear. We hypothesized that a scapulohumeral muscle imbalance, due to a disturbed transverse force couple (TFC) between the anterior and posterior rotator cuff muscles, may have a role in the pathogenesis of the type B morphology.
