OBJECTIVE This study compares the effect of wrist immobilization with non-immobilization on shoulder abduction, shoulder flexion, and shoulder rotation during feeding. METHOD Twenty right-hand-dominant participants with no upper-extremity dysfunction performed a controlled feeding activity under 2 separate wrist conditions: (1) while wearing a static wrist orthosis and (2) with the wrist not ...

Background: Identifying the predisposing factors of neck and shoulder complaints and finding solutions to avoid them could improve the occupational health condition of the nurses. In this study, we aimed at determining the role of psychological and physical occupational factors in developing neck and shoulder complaints among the participants.   Methods: This analytic cross-sectional st...

INTRODUCTION The spectrum of pathoanatomic lesions encountered in anterior shoulder dislocation is broad. There could be a presence of loose bodies, chondral and osteochondral, in the shoulder joint and also concomitant rotator cuff partial tears resulting from acute and chronic shoulder instability. CASE REPORT We present one case report of a 46-year-old male Chinese with an uncommon case of...

background: work-related musculoskeletal disorders (wrmsds) are considered a major factor in health problems, human injuries, and loss of work time. the aim of the present study was to assess the risk of musculoskeletal disorder (msd) and evaluate the prevalence of msd among female hairdressers.   materials and methods: in this descriptive analytical study, the risk of msds was evaluated in 172...

Frozen shoulder is a chronic condition characterized by pain in the shoulder and restriction of movements in all directions. Some patients are left with long-term limitation of shoulder joint activity with various severities, which results in reduced quality of life. Currently, there is a paucity of literature on the molecular biology of frozen shoulder, and the molecular biological mechanism f...

background : glenoid bone damages consisting of anterior rim erosion and bony avulsion are very important in decision making for treatment of recurrent dislocation in shoulder joint. this study was aimed to determine the prevalence of these damages in patients with anterior recurrent shoulder dislocation. methods : the study was a cross-sectional study evaluating patients with unstable shoulder...

background:  oxford shoulder score is a specific 12-item patient-reported tool for evaluation of patients with inflammatory and degenerative disorders of the shoulder. since its introduction, it has been translated and culturally adapted in some western and eastern countries. the aim of this study was to translate the oxford shoulder score (oss) in persian and to test its validity and reliabili...

Shoulder instability ranges from subtle instability to frank dislocation. Our understanding on the subject is getting better. Patient lifestyle, increased awareness/expectations, better availability of information, improved imaging modalities, and increased awareness about the previously less known concepts in instability all add to the challenges of managing the problem. History and clinical e...

BACKGROUND Rupture in the shoulder region of a coronary atheroma is considered to be a sequel to local extracellular matrix degradation in this highly vulnerable site. Such degradation could be triggered by mast cells, which are filled with neutral proteases and are present in coronary atheromas. However, the distribution and phenotype of mast cells within coronary atheromas have not been studi...

BACKGROUND The Zweymüller stem design has proven long-term stability with a 20-year survival rate of over 90 %. Primary stability necessitates implant-bone micromotions below 150 μm, otherwise bony ingrowth is negatively influenced. METHODS Using fresh paired human femurs, we investigated a modification of the Zweymüller-type stem design with reduced proximal lateral shoulder in reference to ...
