We divided into two groups: 79 overhead athletes and 102 nonathletes groups...

BACKGROUND: The relationship between lower mobility, as measured by the elbow forward translation motion (T-motion) test, a new indicator of shoulder joint complex movement that measures elbow position when both dorsal hands are placed on the iliac crest while in a sitting position, and the parameters calculated by ultrasonography is unknown. The purpose of this study was to investigate the limiting factors of T-motion through motion analysis of the humeral head and rotator cuff muscles using ultrasonography in college baseball players...

BACKGROUND: The purpose of this study was to establish consensus statements via a Delphi process on the factors that should be included in a registry for those patients undergoing rotator cuff tear treatment. METHODS: A consensus process on the treatment of rotator cuff utilizing a modified Delphi technique was conducted. Fifty-seven surgeons completed these consensus statements and 9 surgeons declined. The participants were members of the European Society for Surgery of the Shoulder and Elbow committees representing 23 European countries...

BACKGROUND: Musculoskeletal disorders (MSDs) are a severe occupational health issue among medical radiation practitioners. It is mostly linked to personal protective wear, working posture, tools employed and ergonomics. OBJECTIVE: To assess and evaluate the musculoskeletal disorders among nuclear medicine professionals (NMP) in India. METHODS: An online survey was distributed to 455 NMP throughout India between November 2021 and March 2022 covering the demographic characteristics and questions for evaluation of musculoskeletal symptoms using the Standardized Nordic Musculoskeletal Questionnaire (NMQ)...

PURPOSE: We wished to evaluate if an open-source artificial intelligence (AI) algorithm ( https://www.childfx.com ) could improve performance of (1) subspecialized musculoskeletal radiologists, (2) radiology residents, and (3) pediatric residents in detecting pediatric and young adult upper extremity fractures. MATERIALS AND METHODS: A set of evaluation radiographs drawn from throughout the upper extremity (elbow, hand/finger, humerus/shoulder/clavicle, wrist/forearm, and clavicle) from 240 unique patients at a single hospital was constructed (mean age 11...

INTRODUCTION: Mirror hand is an extremely rare congenital abnormality characterized by polydactyly and duplication of the ulna, with the absence of the radius and thumb. Atypical presentations of mirror hand were described, including the presence of the radius in a few cases; here the authors report one of the atypical cases of mirror hand that underwent successful management. CASE PRESENTATION: A 2-year-old and 7-month-old female child presented with 7 well-developed digits, with an absent thumb; the X-ray imaging of the forearm showed a well-formed ulna and radius with proximal fusion...

INTRODUCTION: Distal biceps tendon repair is usually performed via a double-incision or single-incision bicortical drilling technique. However, these techniques are associated with specific complications and usually do not allow for anatomical footprint restoration. It was the aim of this study to report the clinical results of a double intracortical button anatomical footprint repair technique for distal biceps tendon tears. We hypothesized that this technique would result in supination strength comparable to the uninjured side with a low re-rupture rate and minimal bony or neurological complications...

INTRODUCTION: Progressive pseudorheumatoid dysplasia is a rare autosomal recessive disorder caused by a mutation in the Wnt1-inducible signaling protein 3 gene, with few cases reported. CASE REPORT: We discuss the case of a 19-year-old Caucasian male patient with polyarticular involvement, including shoulders, elbows, wrists, hands, spine, hips, knees, and notably the ankles. Despite a well-conducted medical treatment, due to the rapid progression of his condition, the patient underwent bilateral total hip and knee arthroplasties, as well as left ankle replacement...

BACKGROUND: Subjects with Charcot-Marie-Tooth (CMT) disease show hands impairment which is a relevant problem affecting the quality of life. This symptom is related to muscle weakness and reduced motor coordination of the upper limb. However, most studies focus on lower limb impairment, therefore the investigation of upper limb disability is necessary to identify biomarkers able to monitor disease-specific features and to tailor rehabilitation. OBJECTIVE: This study aimed at characterizing upper limb muscle co-contraction using the co-contraction index (CCI) in CMT population...
