Joint instability creates a clinical and economic burden in the health care system. Injuries and disorders that directly damage the joint structure or lead to joint instability are highly associated with osteoarthritis (OA). Thus, understanding the physiology of joint stability and the mechanisms of joint instability-induced OA is of clinical significance. The first section of this review discu...

The results of transosseous osteosynthesis for humerus dislocation-fractures using external fixation device were analysed. There 9 patients with such injury. assembling and tactics treatment described. In 8 follow-up period ranged from 1 to years. One patient had an excellent result full restoration shoulder joint function. 4 the outcomes good in 3 satisfactory.

Introduction: Fractures of the distal end clavicle account for 10% - 30% all fractures this bone, however, they as many 50% nonunions and malunions in fractures. Of fractures, highest percentage complications appertain to Neer type IIB The aim paper is describe case a female patient with fracture treated by reduction flexible stabilization coracoclavicular joint using TightRope system. Case rep...

The overhead-throwing athlete is a challenging sports medicine patient. The repetitive microtraumatic stresses imposed on the athlete's shoulder joint complex during the throwing motion constantly places the athlete at risk for injury. These stresses may effect several adaptations to normal shoulder range of motion, strength, and scapula position. The clinician should therefore appreciate the u...

The purpose of this study was to identify the characteristics of muscular strength in upper limb and to present the preliminary information for development of sports injury prevention program and exercise rehabilitation program in wheelchair tennis players. Participants were 12 male wheelchair tennis players. Muscular strength was measured in shoulder and elbow joints with isokinetic dynamomete...

background: to validate the persian version of the simple shoulder test in patients with shoulder joint problems.   methods: following beaton`s guideline, translation and back translation was conducted. we reached to a consensus on the persian version of sst. to test the face validity in a pilot study, the persian sst was administered to 20 individuals with shoulder joint conditions. we enrolle...

background:  the glenohumeral joint becomes dislocated more than any other major joint because it maintains a wide range of motion and its stability is inherently weak. the most common complication following acute initial shoulder dislocation is recurrent dislocation or chronic instability. imbalance of strength and range of motion in individuals with anterior dislocation can be a contributing ...

background: magnetic resonance imaging (mri) has long been considered a perfect imaging study for evaluation of shoulder pathologies despite occasional discrepancies between mr reports and arthroscopic findings. in this study we aim to evaluate impact of imaging center as an indicator of image quality on accuracy of mri reports in diagnosis of rotator cuff tendon pathologies. methods: we review...

background: the objective of this study was to determine the diagnostic value of magnetic resonance imaging for shoulder joint pathologies and then compare the results with arthroscopy, the standard for joint diagnosis. methods: in this cross-sectional study, 80 patients with shoulder joint disorders, who underwent final arthroscopy, were studied. based on patients’ medical history and physical...
