A new method to evaluate the influence of the glenosphere positioning on stability and range of motion of a reverse shoulder prosthesis
2019
Abstract Purpose Shoulder instability and reduced range of motion are two common complications of a total reverse shoulder arthroplasty. In this work, a new approach is proposed to estimate how the glenoid component positioning can influence the stability and the range of motion of a reverse shoulder prosthesis. Materials and methods A standard reverse shoulder prosthesis has been analysed. To perform virtual simulation of the shoulder-prosthesis assembly, all the components of the prosthesis have been acquired via a 3D laser scanner and the solid models of the shoulder bones have been reconstructed through CT images. Loads on the shoulder joint have been estimated using anatomical models d…
Rehabilitation following injury of the rotator cuff
2003
The main aim of this paper is to compare two diffrent rehabilitation tecniques for treatment of the shoulder joint following injury of the rotator cuff. The seriousness of the pathology means patients generally have to endure a considerable period during wich use of the joint in question is impossible
Optimal positioning of the humeral component in the reverse shoulder prosthesis.
2014
Total reverse shoulder arthroplasty is becoming more and more the standard therapeutic practice for glenohumeral arthropathy with massive lesions of the rotator cuff. The biomechanical principle of this prosthesis is represented by the reversion of the normal anatomy of the shoulder joint. This non-anatomical prosthesis leads to a medialization of the rotation centre of the glenohumeral joint and also to a distalization of the humeral head. All that causes a deltoid tension increasing so allowing a larger abduction of the arm. Main complications of the reverse shoulder prosthesis are due to the joint instability, the scapular notching and the wear of the polyethylene insert. The main goal o…
