Grip on prognostic factors after forearm fractures

The subject of this thesis was to get more knowledge and understanding of our available imaging and interpretation of non-invasive tests to predict the outcome of a specific treatment. We started this research by testing available qualification systems for plain radiography of the wrist after a forearm fracture. Though there are different fracture types of wrist fractures, which are generally acknowledged, variability of scoring them among traumatologists is high. Meaning there is no agreement for a proper classification system, hence agreement for different treatment options.However, some fractures can easily be characterised and as a group being followed. Therefore an objective measurement as a tool would be ideally, which we ought to found in grip measurement. While commonly the non index arm could suffice as control, there always will be a difference because of hand preference. A study was conducted to observe what would be normal in a healthy juvenile population for both hands, taking hand preference in consideration. Also a study was conducted in a healthy adult population for normative data of pronation (forearm endorotation) and supination (forearm exorotation) strength of the forearm.The results of the normative adult group data were used to relate decreased pronation and supination strength to the same strength measurements in patients with a ligament injury. This ligament injury is specific for a certain fracture type.
