Osteoarthritis (O.A) affects over 50 million Americans. This includes mostly O.A of the shoulder, hip, and knee. Shoulder osteoarthritis (O.A) has been demonstrated in cadaver and radiographic studies to affect up to 33% of patients over the age of 60 [1]. Patients with shoulder O.A have pain, crepitus, decreased ability to place their hand at a desired point in space and loss of motion, severe...

OBJECTIVE In overhead sports such as volleyball, baseball, or tennis shoulder problems are very common. The aim of this study was to identify features which may correlate with shoulder problems in volleyball attackers. METHODS 30 competitive volleyball attackers (mean age 25 years) were included in the study; 15 were suffering from shoulder pain and 15 had no history of shoulder pain. The res...

BACKGROUND Acromial morphology has previously been defined as a risk factor for some shoulder pathologies. Yet, study results are inconclusive and not all major shoulder diseases have been sufficiently investigated. Thus, the aim of the present study was to analyze predictive value of three radiological parameters including the critical shoulder angle, acromion index, and lateral acromion angle...

Shoulder joint is a complex integration of soft and hard tissues. It plays an important role in performing daily activities and can be considered as a perfect compromise between mobility and stability. However, shoulder is vulnerable to complications such as dislocations and osteoarthritis. Finite element (FE) models have been developed to understand shoulder injury mechanisms, implications of ...

Shoulder pain is a common musculoskeletal ailment. The process of determining the etiology of shoulder pain can be difficult. The differential diagnoses include: both intracapsular and extracapsular lesions; and neurologic, vascular, postural, and visceral causes. We present an unusual case of shoulder pain accompanied by loss of shoulder range of motion (ROM), initially thought to be caused by...

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 ...

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...
