Isolated, full-thickness chondral lesions of the glenohumeral joint are a significant pathology encountered by laborers, athletes, and the elderly. A thorough history should be obtained in any patient presenting to the office with shoulder pain and concern for the etiology being an articular cartilage defect. The first-line imaging should include plain radiographs of the glenohumeral joint; MRI...

A recent paper has described a new functional method, the symmetrical centre of rotation (SCoRE), for locating joint centre position [Ehrig, R.M., Taylor, W.R., Duda, G.N., Heller, M.O., 2006. A survey of formal methods for determining the centre of rotation of ball joints. Journal of Biomechanics 39 (15), 2798-2809]. For in vitro analyses, the SCoRE method showed better precision than helical ...

ont matter & 2006 006.10.004 thor. [email protected] Summary The treatment of combined glenohumeral arthritis and massive rotator cuff deficiency remains a unique challenge. Prosthetic reconstruction is aimed at restoring the normal kinematics of the glenohumeral joint. The reverse shoulder prosthesis medialises the centre of rotation of the glenohumeral joint, thereby lengthening the deltoid lev...

In children with brachial plexus birth palsy, the unopposed contraction of the shoulder internal rotators and adductors, secondary to weakness of the external rotators and abductors, leads to internal rotation contracture of the shoulder joint. Latissimus dorsi and/or teres major tendon transfers combined with open musculotendinous lengthening can improve shoulder function. Arthroscopic release...

BACKGROUND Joint injections and aspirations are used to reduce joint pain and decrease inflammation. The efficacy of these injections is diminished when they are placed inadvertently in the wrong location or compartment. The purpose of this study was to determine whether the use of varying sites or imaging techniques affects the rate of accurate needle placement in aspiration and injection in t...

OBJECTIVE In this study, we aimed to assess whether therapeutic taping for scapular stabilization affected scapulothoracic, glenohumeral, and humerothoracic joint function in children with brachial plexus birth palsy and scapular winging. METHOD Motion capture data were collected with and without therapeutic taping to assist the middle and lower trapezius in seven positions for 26 children. D...

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...

. Historically, 96% of shoulder dislocations have been attributed to a traumatic episode with anterior dislocation accounting for 97% of these. . Traumatic dislocation of the glenohumeral joint is the most common joint dislocation with an incidence of 8.2 to 23.9 per 100,000 per year. The male to female ratio is 2.55: 1 with almost 50% occurring in patients between the age of 15 years and 29 ye...
