shoulder elbow hand

OBJECTIVES: Despite the fact that team manual handling is common in different working environments, the previous studies in this regard, particularly those with a physiological approach are quite limited. The present study is an attempt to model the heart rate (HR) of individual and team manual handling with one hand. METHODS: Twenty-five young men (aged 21.24±1.42 year) volunteered for this study. The experiments included individual and two-person handling of the load with three different weights with and without height difference...

BACKGROUND: While microfracture has been shown to be an effective treatment for chondral lesions in the knee, evidence to support its use for chondral defects in the shoulder is limited to short-term outcomes studies. The purpose of this study is to determine if microfracture provides pain relief and improved shoulder function in patients with isolated focal chondral defects of the humeral head at a minimum 5-year follow-up. METHODS: Patients who underwent microfracture procedure for isolated focal chondral defects of the humeral head with a minimum follow-up of 5 years between 02/2006 and 08/2016 were included...

BACKGROUND: Corticosteroids (CS) have shown good short-term performance in terms of pain relief and functional improvement. However, the safety and long-term efficacy of this treatment remains controversial. Several studies have reported good results of platelet-rich plasma (PRP) in the treatment of tendinopathies. However, whether its use in the treatment of lateral epicondylitis (LE) is superior to that of CS remains controversial. PURPOSE: To perform a systematic review and meta-analysis of original studies to determine whether the prognosis of LE patients treated with PRP is better than that of CS...

BACKGROUND: The efficacy of Kinesio tape (KT) in lateral elbow tendinopathy (LET) has been widely discussed, but controversy remains. OBJECTIVES: To perform a meta-analysis of randomized controlled trials (RCTs) in the literature to ascertain the efficacy of KT in LET. DESIGN: Systematic review and meta-analysis. METHOD: Two independent reviewers carried out a literature search in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines...

BACKGROUND: The flexor pronator slide is an effective treatment option for ischemic contracture and contracture related to spastic cerebral palsy, but little is known about the use of the flexor pronator slide in other non-ischemic contractures. I propose a flexor pronator slide to simultaneously correct wrist and finger flexor contractures and preserve the muscle resting length. To avoid overcorrection of the deformity, I propose the use of a wide-awake local anesthesia with no tourniquet (WALANT) procedure, in which the patient is able to continually assist the surgeon in assessing the contracture release and improvement in finger movement...

BACKGROUND: Elbow flexion contracture development in school-age children with a brachial plexus birth injury (BPBI) is common. Reports indicate onset between 2 and 4 years; however, little is known about early childhood prevalence, development, and trajectory of these contractures. PURPOSE: To determine the prevalence and predictors of BPBI elbow flexion contractures during early childhood. STUDY DESIGN: A retrospective cross-sectional study...

BACKGROUND: Previous studies have reported that abnormal interlimb coordination is a typical characteristic of motor developmental delay (MDD) during human movement, which can be visually manifested as abnormal motor postures. Clinically, the scale assessments are usually used to evaluate interlimb coordination, but they rely heavily on the subjective judgements of therapists and lack quantitative analysis. In addition, although abnormal interlimb coordination of MDD have been studied, it is still unclear how this abnormality is manifested in physiology-related kinematic features...

BACKGROUND: Women are underrepresented in the orthopaedic surgery workforce in the U.S. The purpose of this study was to elucidate the representation of women among fellowship program directors (PDs) in orthopaedic surgery. METHODS: This was a retrospective cohort study of fellowship PDs in orthopaedic surgery during the 2022 to 2023 academic year. Academic, training, and demographic characteristics were collected from internet-based resources. Participation-to-prevalence ratios (PPRs) were calculated for both men and women...

INTRODUCTION: Rapid technological developments, especially in the use of electronic devices, have affected workers. MSDs are a major burden for both employees and employers, and in contemporary society. Millions of computer workers suffer musculoskeletal diseases and it is the most common cause of occupational illness in the USA and result in medical costs and absenteeism that cost the sector between $45 and $54 billion annually. A single review was done about WMSDs, however it only investigated neck and upper extremities disorders...

HYPOTHESIS AND BACKGROUND: It is known that, though widely used, shoulder range of motion (ROM) measurements are not standardized and have a high rate of intra- and interobserver differences. Particularly, the inconsistency in quantitative and qualitative measurements and their relationship to patient-reported outcome measures (PROMs) make shoulder health difficult to determine. METHODS: This was a prospective study of 147 patients who presented with a chief complaint of shoulder pain to the orthopedic sports medicine and shoulder clinic of a single fellowship-trained surgeon...

PURPOSE: The goal of this study was to develop a dynamic elbow testing apparatus that reproduces active joint motion at different shoulder positions to quantify the capabilities of total elbow arthroplasty designs. METHODS: We designed a testing apparatus to create active cyclic elbow joint motion in human cadaveric and sawbones composite upper extremities. Two pneumatic actuators recreated humerus-originating muscles while rubber bands simulated forearm muscle action...

BACKGROUND: An olecranon stress fracture (OSF) is a rare injury most commonly seen in high-level overhead throwing athletes with no clear consensus on surgical treatment. The most common surgical treatment described in the literature is cannulated screw fixation but there have been high rates of reported hardware irritation and need for subsequent hardware removal. HYPOTHESIS/PURPOSE: This study describes a novel surgical technique in the treatment of OSFs in high-level throwing athletes using retrograde headless compression screws...

BACKGROUND: Proximal humerus fracture (PHF) is a common fragility fracture in older adults and can have a substantial impact on upper limb function. Although most patients with PHF can be treated non-surgically, it is unknown whether older adults benefit from supervised exercise therapy after PHF. Therefore, the objective of this trial was to investigate whether 10 weeks of physiotherapist-supervised exercises once a week was superior to 10 weeks of non-supervised home-based exercises in older adults with a non-surgically treated displaced 2-part PHF...

BACKGROUND: Although isolated distal radius and radial head fractures are common injuries, simultaneous ipsilateral fractures are uncommon. They can range from simple undisplaced fractures at either end to severely comminuted ipsilateral proximal and distal radial fractures. Few cases have been reported with concomitant comminuted distal radius and radial head fractures, and no treatment guidelines are available. Decisions are often based on personal recommendations. The purpose of our study is to increase awareness of this injury pattern and to discuss the mechanism of injury, treatment approach, and functional outcome...

BACKGROUND: Deficiency in scapular muscle endurance (SME) is a risk factor for rotator-cuff-related shoulder pain (RCRSP). However, the exact relationship among SME, pain, and functionality remains unclear. This study aims to compare SME, pain, and functionality in RCRSP patients to those in age-gender-matched healthy controls. METHODS: Twenty-three patients with RCRSP and 23 age-gender matched healthy controls were included in the study. SME was measured using a 1-kg dynamometer...

PURPOSE: To determine the outcomes of endoscopic olecranon bursectomy for the treatment of recalcitrant olecranon bursitis in one surgeon's practice. METHODS: A retrospective analysis was conducted on all patients who underwent an endoscopic olecranon bursectomy for the treatment of recalcitrant olecranon bursitis between January 2018 and May 2021 at one surgeon's practice. Demographic variables as well as causes for olecranon bursitis such as aseptic, septic, and gouty tophi were recorded...

Because of the nature and positioning of their work, dental professionals are at a relatively high risk for musculoskeletal disorders (MSDs) and shoulder injuries. The most common injuries occur in the neck, back (spine), shoulders, elbows, and hands. Poor posture and fatigue are the most significant causes of MSDs. Poor posture, repetitive motions, and working in awkward positions cause MSDs and shoulder injuries in dental professionals. The use of ergonomic supports can be effective in preventing MSDs and shoulder injuries...

BACKGROUND: Management of displaced distal clavicle fractures remains a topic of discussion due to notoriously high non-union rates, but there is little documented in the literature as to what effect this may have on patient-reported function. The aim of this systematic review was to look at non-operative management following displaced distal clavicle fractures to determine union rates, complications and patient reported outcome measures. METHOD: A review of the online databases MEDLINE and Embase was conducted, according to PRISMA guidelines...

BACKGROUND: The shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) and Patient Rated Wrist/Hand Evaluation (PRWHE) are commonly used questionnaires to assess patient-reported hand function. Information about the measurement properties of the Dutch versions is scarce. OBJECTIVE: To gain insight into the measurement properties of the Dutch language versions of the QuickDASH and the PRWHE in patients with (non)specific complaints of the hand, wrist, forearm and elbow...

Upper extremity kinematics are important for understanding functional ability and performance improvements. The Box and Blocks test (BBT) is a standardized functional test used to measure manual dexterity when evaluating children or patients following a stroke. The BBT measures the number of blocks moved in one minute and therefore, kinematic measures and compensatory strategies cannot be assessed. This study examined the correlation between upper extremity kinematics and cycle time per block movement during the BBT in three age groups (7-, 9-, and 11-year-olds)...
