Shoulder elevation, defined here as arm raising, being essential for activities of daily living, dysfunctions represent a substantial burden in patients' lives. Owing to the complexity of the shoulder joint, the tightly coordinated muscular activity is a fundamental component, and neuromuscular impairments have devastating effects. A single-joint shoulder type version of the Hybrid Assistive Limb (HAL) allowing motion assistance based on the intention of the user via myoelectric activation has recently been developed, and its safety was demonstrated for shoulder rehabilitation...

This study employs first-principles calculations to elucidate the properties of sliding bilayer germanene (BLGe). The buckled structure of germanene can afford a greater number of metastable stacking configurations than planar graphene and enrich the electronic properties. Herein, a detailed analysis of the structural variety, shift-dependent energy bands, and spatial charge densities of BLGe is presented. The projected density of states (PDOS) reveals diverse structures such as plateaus, dips, symmetric/asymmetric peaks, and shoulders...

BACKGROUND: Dislocation of the shoulder joint is the most common type of joint dislocation. It is rare to be in a persistent dislocation that has not been reset. Successful arthroscopic treatment of the obsolete shoulder is relatively uncommon. CASE REPORT: We report a rare case of persistent anterior dislocation of the old shoulder joint in a 30-year-old female patient. The patient underwent an emergency shoulder dislocation at a local hospital after a traumatic injury and re-dislocated persistently after surgery...

BACKGROUND: Although Grammont-style reverse total shoulder arthroplasty (RSA) showed excellent clinical results in Europe, its utility for Asian populations remains unclear. This study aimed to compare the French and Japanese populations in terms of range of motion (ROM), functional outcomes, and scapular notching rates in patients who underwent standard Grammont-style RSA. We hypothesized that RSA for the Japanese population may not provide as good ROM and functional results at the final follow-up as that for the French population...

PURPOSE: Software algorithms are increasingly available as clinical decision support tools (CDSTs) to support shared decision-making. We sought to understand if patient-specific predictions from a CDST would impact orthopedic surgeons' preoperative planning decisions and corresponding confidence. METHODS: We performed a survey study of orthopedic surgeons with at minimum of 2 years of independent shoulder arthroplasty experience. We generated patient profiles for 18 faux cases presenting with glenohumeral osteoarthritis and emailed 93 surgeons requesting their recommendation for anatomic or reverse total shoulder arthroplasty for each case and their certainty in their recommendation on a 4-point Likert scale...

BACKGROUND: Reverse total shoulder arthroplasty (RTSA) can decrease shoulder pain and improve function. However, results reportedly deteriorate as patients approach mid-term follow-up and little is known about how this impacts physical health-related quality of life (PHRQOL) and mental health-related quality of life (MHRQOL). The study hypothesis was that shoulder function, pain, and medication use for pain would influence PHRQOL and MHRQOL. METHODS: This prospective cohort study involving subjects from 6 orthopedic clinics and 12 fellowship-trained surgeons evaluated the influence of RTSA on PHRQOL, MHRQOL, shoulder function, pain, instability, and medication use over the initial 7 years of a 10-year study, and device survivorship and revision rates...
