OBJECTIVE To assess differences in glenohumeral joint rotatory range of movement in javelin throwers between the throwing and non-throwing arm. METHOD A universal 360 degrees goniometer was used to assess glenohumeral joint external and internal rotation range in 90 degrees of shoulder abduction in a group of ten senior international javelin throwers. RESULTS Both arms had significantly gre...

  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 enrol...

Acromioclavicular dislocation (AC dislocation) is a common injury of the shoulder. In contrast to a traumatic cause, nontraumatic dislocation is very rare. We report on a 17-year-old female that presented with voluntary recurrent dislocation of the right AC joint followed by recurrent pain without instability of the ipsilateral shoulder. Clinical examination showed crepitation as well as palpit...

The present report describes a case where typical findings of traumatic glenohumeral interposition of rotator cuff stumps were surgically confirmed. This condition is a rare complication of shoulder trauma. Generally, it occurs in high-energy trauma, frequently in association with glenohumeral joint dislocation. Radiography demonstrated increased joint space, internal rotation of the humerus an...

Coracoid process fractures are rare and often associated with dislocations of the acromioclavicular (AC) joint. There is little evidence about the treatment of these injuries in adolescents, but the few case reports published recommend surgery. We report a case of a dislocated epiphyseal fracture to the base of the coracoid process with AC joint dislocation in a 14-year-old ice-hockey player fo...

recurrent dislocation is not common in small joints. this report presents a new case of chronic recurrent dislocation of proximal interphalangeal joint of the finger in which soft tissue injuries have a role in the dislocation. the patient was a 23 years old man who had referred to our center because of recurrent dislocation of proximal interphalangeal joint of his right ring finger during spor...

To investigate the causes of the overuse shoulder joint injury, the tennis serve of a wheelchair tennis player was analysed twice, before and after a period of training, and compared with that of an able-bodied tennis player. A validated specific protocol of the upper limbs was applied using stereophotogrammetry. The protocol adopted allowed to distinguish differences in the girdle joint that w...

OBJECTIVE To describe the epidemiology of injuries at the Sochi 2014 Winter Paralympic Games. METHODS A total of 547 athletes from 45 countries were monitored daily for 12 days during the Sochi 2014 Winter Paralympic Games (6564 athlete days). Daily injury data were obtained from teams with their own medical support (32 teams, 510 athletes) and teams without their own medical support (13 team...

Neuroprostheses with the use of functional neuromuscular stimulation (FNS) have the potential to restore elbow and shoulder function lost to paralysis because of spinal cord injury (SCI). The human shoulder is highly flexible and thus provides a large range of motion to the arm and hand, although at the expense of precarious stability of the articulations. The complexity of the shoulder has pre...

The Hill-Sachs lesion is an osseous defect of the humeral head that is typically associated with anterior shoulder instability. The incidence of these lesions in the setting of glenohumeral instability is relatively high and approaches 100% in persons with recurrent anterior shoulder instability. Reverse Hill-Sachs lesion has been described in patients with posterior shoulder instability. Gleno...
