Background: Birth-related brachial plexus injury (BRBPI) occurs in 1.2/1,000 births in British Columbia. Even in children with "good" recovery, external rotation (ER) and supination (Sup) are often weaker, and permanent skeletal imbalance ensues. A preventive early infant shoulder passive repositioning program was created using primarily a novel custom splint holding the affected arm in full ER and Sup: the Sup-ER splint. The details of the splint and the shoulder repositioning program evolved with experience over several years. This study reviews the first 4 years.
Methods: A retrospective review of BCCH patients managed with the Sup-ER protocol from 2008 to 2011 compared their recovery scores to matched historical controls selected from our database by two independent reviewers.
Results: The protocol was initiated in 18 children during the study period. Six were excluded due to the following: insufficient data points, non-compliance, late splint initiation, and loss to follow-up. Of the 12 matches, the Sup-ER group final score at 2 years was better than controls by 1.18 active movement scale (AMS) points (p = 0.036) in Sup and 0.96 AMS points in ER (but not statistically significant (p = 0.13)). Unexpectedly, but importantly, during the study period, zero subjects were assessed to have the active functional criteria to indicate brachial plexus reconstruction, where previously we operated on 13 %.
Conclusions: Early application of passive shoulder repositioning into Sup and ER may improve outcomes in function of the arm in infants with BRBPI. A North American multi-site randomized control trial has been approved and has started recruitment.

Effect of concentric exercise-induced fatigue on proprioception, motor control and performance of the upper limb in handball players.

Background: The last phases of a competitive game are when shoulder injuries most commonly happen, and fatigue is thought to be a major contributing factor, perhaps because of reduced proprioception and motor control. The purpose of this study was to investigate the effect of concentric fatigue on proprioception, motor control, and performance of the upper limb in handball players.
Methods: Forty-six right-handed handball players (all males, age 26.
Purpose: Shoulder dislocations in professional football are severe injuries with an increasing incidence and considerable layoff times. Unlike other football injuries, the mechanisms leading to shoulder dislocations are not well understood, which limits the development of targeted preventive measures. Thus, the aims of this study were: (1) to analyse injury mechanisms of shoulder dislocations in professional football, (2) to evaluate situational and (3) to assess kinematic patterns by performing a systematic video analysis.

Background: Sternoclavicular joint dislocation (SJD) is rare, and joint instability after dislocation easily leads to deformity, pain, and limitations in performing activities, often requiring surgical treatment. Currently, there is no ideal internal fixation method for SJD.
Case Presentation: We report the case of a 38-year-old female patient with anterior dislocation of the right sternoclavicular joint (SJ) caused by a car accident who underwent open reduction and internal fixation using the double plate technique combined with the cable technique.

Background: The mechanisms underlying osteoarthritis (OA) remain unclear, and effective treatments are lacking. This study aims to identify OA-related genes and explore their potential in drug repositioning for OA treatment.
Methods: Transcriptome-wide association studies (TWAS) were performed using genome-wide association studies summary data and expression quantitative trait loci data from the Genotype-Tissue Expression project.

Background: The shoulder is the joint most often affected by dislocations. It is known that bony defects of the glenoid and/or humerus can lead to recurrent dislocations even after arthroscopic shoulder stabilization. To prevent recurrent instability, it appears reasonable to reduce fresh and larger Hill-Sachs lesions (off-track lesions).
