A rotator cuff tear causes shoulder pain and limits movement of the shoulder joint. A chronic degenerative change or impingement is the reason for a rotator cuff tear. Diagnosis is made based on medical history and, physical and radiological examinations. Other causes of shoulder pain include calcific tendinitis, degenerative arthropathy, joint dislocation, fracture, and primary or metastatic n...

Background: The Global Unite Shoulder System is the next generation of implant from the Depuy Global Shoulderline. The primary feature of the Global Unite is adaptability through the interchangeable modular bodies, modular suturecollars, and stems. Short-term functional and radiographic outcomes of the Global Unite Platform Shoulder Systemwere assessed as well as complication and revision rates...

  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...

OBJECTIVES To investigate the course and prognosis of shoulder pain in the first 6 months after presentation to the general practitioner. We separately studied patients with acute, subacute and chronic shoulder pain, as duration of symptoms at presentation has been shown to be the strongest predictor of outcome. METHODS A prospective cohort study with 6 months follow-up was carried out in The...

INTRODUCTION Shoulder dislocations are a very common entity in routine orthopaedic practice. Chronic unreduced anterior dislocations of the shoulder are not very common. Neurological and vascular complications may occur as a result of an acute anterior dislocation of the shoulder or after a while in chronic unreduced shoulder dislocation. Open reduction is indicated for most chronic shoulder di...

The shoulder joint has some specific properties in the human body. It has adjusted to the mechanical demands of a vertical body position more than any other joint. The shoulder has the largest motion range of all joints in the human body. In addition to the shoulder is exposed cosmetically, particularly in women. Extensive surgical exposures of the shoulder joint were commonly used when shoulde...

OBJECTIVES To investigate shoulder rotator strength and steadiness in athletes with anterior instability and superior labrum anterior posterior (SLAP) lesion. DESIGN Cross-sectional laboratory study. METHODS Athletes with anterior shoulder instability (instability group, n=10) and a SLAP lesion (SLAP group, n=10) were compared with healthy athletes matched by age, anthropometrics and sport ...

The biceps brachii is a bi-articular muscle affecting motion at the shoulder and elbow. While its' action at the elbow is well documented, its role in shoulder elevation is less clear. Therefore, the purpose of this project was to investigate the influence of shoulder and elbow joint angles on the shoulder elevation function of the biceps brachii. Twelve males and 18 females were tested on a Bi...

CHARLES A. THIGPEN: Effects Of Forward Head And Rounded Shoulder Posture On Scapular Kinematics, Muscle Activity, And Shoulder Coordination (Under the direction of Dr. Darin A. Padua) Forward head and rounded shoulder posture (FHRSP) has been identified as a potential risk factor for the development of shoulder pain. The mechanism through which forward head and rounded shoulder can facilitate s...
