BACKGROUND: Most patients in Indonesia present with large-sized thyroid nodules, which need surgical removal to exclude malignancy. Many surgeons prefer endoscopic thyroidectomy to avoid a large and visible surgical scar on the neck and to reduce postoperative complications. This study aims to evaluate and analyze surgical feasibility, safety, oncologic outcome, and patient satisfaction of endoscopic thyroidectomy via the axillary-breast-shoulder approach. METHODS: Between August 2010 and September 2015, 42 endoscopic thyroidectomies via the axillary-breast-shoulder approach with carbon dioxide insufflation up to 8-10 mmHg were performed and retrospectively reviewed...

BACKGROUND: Professional musicians show a high prevalence of musculoskeletal pain, but information is limited about prevalence of pain compared to the general populations. AIMS: Our cross-sectional epidemiological study compared the prevalence of musculoskeletal pain between professional orchestra musicians and the working population in Finland. METHODS: Musicians with a permanent contract with all domestic professional symphony and philharmonic orchestras and a population sample of the workforce in Finland completed questionnaires including the same questions on musculoskeletal pain and on various other issues...

The muscle specific isoform of the supervillin protein (SV2), encoded by the SVIL gene, is a large sarcolemmal myosin II- and F-actin-binding protein. Supervillin (SV2) binds and co-localizes with costameric dystrophin and binds nebulin, potentially attaching the sarcolemma to myofibrillar Z-lines. Despite its important role in muscle cell physiology suggested by various in vitro studies, there are so far no reports of any human disease caused by SVIL mutations. We here report four patients from two unrelated, consanguineous families with a childhood/adolescence onset of a myopathy associated with homozygous loss-of-function mutations in SVIL...

PURPOSE: Health-related quality of life (HRQoL) becomes increasingly relevant in an aging society. Functional outcome (FO) and the patient-reported outcome (PRO) after surgical treatment of proximal humerus fractures (PHF) depends on numerous factors, including patient- and injury-specific factors. There is little evidence on how the FO and the PRO vary in different settings such as monotrauma or multiple injuries, even though the PHF is one of the more frequent fractures. In addition, to a previous study, on multiple injured patients and upper extremity injuries, the aim of the current study was to investigate the impact of multiple injuries, quantified by the ISS, on the FO and PRO after surgically treated PHF by PHILOS...

Bursae are small, jelly-like sacs that are located throughout the body, mainly around the shoulder, elbow, hip, knee, and heel in a number over 150. They contain a small amount of fluid, and are positioned between bones and soft tissues, acting as cushions to help reduce friction. Pes anserinus bursae, despite being clinically frequent, are not visible either by ultrasound (US) or magnetic resonance image (MRI). In some cases, we may observe a small fluid collection. The present case-report demonstrates the full clinical picture of a giant pes anserinus bursae beginning from clinical observation to its final pathology exam...

BACKGROUND: We hypothesized that in a cadaveric massive rotator cuff tear (MCT) model, a fascia lata (FL) allograft superior capsular reconstruction (SCR) would restore subacromial contact pressure and humeral head superior translation without limiting range of motion (ROM). Therefore, the objective of this study was to compare these parameters between an intact rotator cuff, MCT, and allograft FL SCR. METHODS: Eight fresh cadavers were studied using a custom shoulder testing system...

BACKGROUND: Recent efforts to contain health care costs and move toward value-based health care have intensified, with a continued focus on Medicare expenditures, especially for high-volume procedures. As total shoulder arthroplasty (TSA) volume continues to increase, especially within the Medicare population, it is important for orthopedic surgeons to understand recent trends in the allocation of health care expenditures and potential effects on reimbursements. The purpose of this study was to evaluate trends in annual Medicare utilization and provider reimbursement rates for shoulder arthroplasty procedures between 2012 and 2017...

BACKGROUND: Shoulder injuries account for a large portion of all recorded injuries in professional baseball. Much is known about other shoulder pathologies in the overhead athlete, but the incidence and impact of acromioclavicular (AC) joint injuries in this population are unknown. We examined the epidemiology of AC joint injuries in Major League Baseball (MLB) and Minor League Baseball (MiLB) players and determined the impact on time missed. METHODS: The MLB Health and Injury Tracking System was used to compile records of all MLB and MiLB players from 2011 to 2017 with documented AC joint injuries...

BACKGROUND: The purpose of this study was to determine the factors associated with outcomes after reverse total shoulder arthroplasty (RTSA). METHODS: We retrospectively evaluated all RTSAs performed by the senior author between January 1, 2007, and November 1, 2017. We evaluated pain visual analog scale (VAS), Simple Shoulder Test (SST), and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) scores and complication and reoperation rates at a minimum of 2-year follow-up...

BACKGROUND:  After discharge from a rehabilitation center the continuation of therapy is necessary to secure already achieved healing progress and sustain (re-)integration into working life. To this end, home-based exercise programs are frequently prescribed. However, many patients do not perform their exercises as frequently as prescribed or even with incorrect movements. The telerehabilitation system AGT-Reha was developed to support patients with shoulder diseases during their home-based aftercare rehabilitation...

BACKGROUND: The purpose of this study was to quantify correction of glenoid deformity and humeral head alignment in anatomic total shoulder arthroplasty (TSA) as a function of preoperative pathology (modified Walch classification) and glenoid implant type in a clinical cohort using three dimensional (3D) computed tomography (CT) analysis. METHODS: Patients undergoing anatomic TSA with a standard glenoid (SG) (n=110) or posteriorly stepped augmented glenoid (AG) (n=62) component were evaluated with preoperative CT and a postoperative CT within 3 months of surgery...

BACKGROUND: Reverse total shoulder replacement in elderly patients with primary osteoarthritis (OA) and rotator cuff pathology is increasing, the purpose of our study was to determine the medium term results of anatomic total shoulder replacement (TSR) for OA in patients with established preoperative partial thickness rotator cuff tears on MRI scans. METHODS: We reviewed a cohort of patients who had undergone anatomical TSR for OA with a preoperative MRI diagnosis of partial thickness rotator cuff tear...

BACKGROUND: The use of reverse total shoulder arthroplasty (RTSA) spreads worldwide due to an expansion of indications and an aging society. The value of RTSA for very old patients is rarely analyzed. This study was conducted to investigate the outcome of primary RTSA in patients older than 80 years of age. METHODS: We identified 171 shoulders (159 patients), treated with a RTSA at an age of more than 80 years between January 2005 and March 2018. The primary outcome parameters were Subjective Shoulder Value (SSV) and the Constant-Murley Scores, mortality, complications, and reoperation rates...

BACKGROUND: Animal models of brain recovery identify the first days after lesioning as a time of great flux in sensorimotor function and physiology. After rodent motor system lesioning, daily skill training in the less affected forelimb reduces skill acquisition in the more affected forelimb. We asked whether spontaneous human motor behaviors of the less affected upper extremity (UE) early after stroke resemble the animal training model, with the potential to suppress clinical recovery...

PURPOSE: The European Society for Sports traumatology, Knee surgery and Arthroscopy (ESSKA) identified the need to develop a core curriculum for clinical specialists that work within the interest areas of ESSKA. A research-based approach was used to define a set of core competencies which could be used to map all of their educational activities, resources and development priorities. This paper describes the aims, development, results and implications of this competency-based core curriculum for orthopaedic conditions relevant to ESSKA members...

Calcific tendinopathy (CT), developed due to calcium hydroxyapatite deposition in the rotator cuff tendon, mostly affects women in their 40 s and 50 s and causes severe shoulder pain. However, the molecular basis of its pathogenesis and appropriate treatment methods are largely unknown. In this study, we identified 202 differentially expressed genes (DEGs) between calcific and adjacent normal tendon tissues of rotator cuff using RNA sequencing-based transcriptome analysis. The DEGs were highly enriched in extracellular matrix (ECM) degradation and inflammation-related processes...

Background No consensus exists among orthopedic surgeons regarding the optimal intervention for adhesive capsulitis. The purpose of this study was to determine which treatment provides the best objective outcome following manipulation under anesthesia (MUA), MUA + arthroscopic capsular release (CR), or CR alone. Methods Between 2011 and 2015, 97 shoulders were treated for adhesive capsulitis (MUA, MUA+CR, CR) and followed for three months or until achieving full range of motion (ROM). Patients' charts were reviewed for demographic information, diabetes, pre/post-operative ROM, and complications...

Recently, computer vision and deep learning technology has been applied in various gait rehabilitation researches. Considering the long short-term memory (LSTM) network has been proved an excellent performance in learn sequence feature representations, we proposed a lower limb joint trajectory prediction method based on LSTM for conducting active rehabilitation on a rehabilitation robotic system. Our approach based on synergy theory exploits that the follow-up lower limb joint trajectory, i.e. limb intention, could be generated by joint angles of the previous swing process of upper limb which were acquired from Kinect platform, an advanced computer vision platform for motion tracking...
