Abstract

A good functional range of motion of the joints of the upper extremity is extremely important for independent ADL activities in the elderly. In this age group, the proper functioning of joints may be affected by destruction of joint cartilage, loss of muscle function by degeneration or rupture of tendons, and atrophy of muscles such as the rotator cuff in the shoulder.

Joint replacement prostheses for the upper extremity do not have the same good functional results and survival as hip and knee prostheses. Our research line is focussed on improvement of endoprostheses for the upper extremity. Towards this goal, new joint prostheses are evaluated clinically and biomechanically.

Within this project we focus on improving the outcome of total shoulder replacements, highly relevant research that fits perfectly in the internationally recognised expertise and research programme of the department of Orthopaedics. Two projects have already started: in the first project we concentrate on biomechanical modelling of the shoulder, and is intended to gain insight in optimal prosthesis design and placement, in the second project we focus on pre-operative planning of shoulder arthroplasty. In the near future, we plan to start more epidemiological oriented research on the assessment of early arthrosis.
