Journal ArticleDOI
ISB recommendation on definitions of joint coordinate systems of various joints for the reporting of human joint motion-Part II: shoulder, elbow, wrist and hand
Ge Wu,Frans C. T. van der Helm,H.E.J. Veeger,Mohsen Makhsous,Peter Van Roy,Carolyn Anglin,Jochem Nagels,Andrew R. Karduna,Kevin J. McQuade,Xuguang Wang,Frederick W. Werner,Bryan Buchholz +11 more
TL;DR: A definition of a joint coordinate system (JCS) for the shoulder, elbow, wrist, and hand is proposed and a standard for the local axis system in each articulating segment or bone is generated.
Journal ArticleDOI
Stress shielding and bone resorption in shoulder arthroplasty.
TL;DR: It was concluded that stress shielding is a long-term complication of shoulder arthroplasty and that the relative stem size is an important factor in its genesis.
Stress shielding and bone resorption in shoulder arthroplasty
TL;DR: In this article, the authors reviewed the radiographs of sixty-four patients with seventy humeral head replacements for signs of stress shielding and concluded that stress shielding is a longterm complication of shoulder arthroplasty and that the relative stem size is an important factor in its genesis.
Journal ArticleDOI
Calcific Tendinitis of the Rotator Cuff A Randomized Controlled Trial of Ultrasound-Guided Needling and Lavage Versus Subacromial Corticosteroids
Pieter Bas de Witte,Jasmijn W. Selten,Ana Navas,Jochem Nagels,Cornelis P.J. Visser,Rob G H H Nelissen,Monique Reijnierse +6 more
TL;DR: On average, there was improvement at 1-year follow-up in both treatment groups, but clinical and radiographic results were significantly better in the barbotage group.
Journal ArticleDOI
The glenohumeral joint rotation centre in vivo.
TL;DR: The authors prefer the helical-axes method, it is a reliable and valid method which can be applied in movement registration of healthy subjects and patients with a shoulder endoprosthesis, it can be applications in hinge joints to determine a rotation axis instead of a rotation centre which is desirable in standardized upper extremity research, and calculation time is short.
