Wrist osteoarthritis can lead to pain and loss of motion. Scaphoid Lunate Advanced Collapse (SLAC) and Scaphoid Nonunion Advanced Collapse (SNAC) are the most common patterns seen¬¬. Changes in the biomechanics of the proximal row due to the unrestrained (proximal part of the) scaphoid result in an abnormal motion pattern between the scaphoid and radius. Changes in motion patterns will eventually result in wrist osteoarthritis. This thesis aims to improve care (early diagnostics and treatment) for patients with wrist osteoarthritis.
In patients with chronic scapholunate ligament disruption or scaphoid nonunion, the abnormal motion pattern of the scaphoid results in progression of wrist osteoarthritis. In the first part of this thesis, studies on outcomes of different motion-preserving techniques are presented.
Early diagnosis of complex wrist injuries could result in earlier treatment and prevention of the development of wrist osteoarthritis. Understanding carpal kinematics helps recognising and diagnosing wrist injuries. In the second part of this thesis, we used the latest non-invasive method for analysing in vivo kinematics, the four-dimensional CT (4D-CT). The 4D-CT was used to establish a quantitative description of in vivo kinematics of the scaphoid, lunate and capitate in uninjured wrists. These data may serve as normative data for future studies on complex wrist injuries.
The PhD defences will not take place publicly in the usual way. A live stream link has been provided to candidate. The ceremony will begin exactly at 10:30.
