- Primary Outcome Measures
Name Time Method The aim is to quantify the free range of motion (rotation) of the radius relative to the ulna and the proximodistal translation in the distal radioulnar joint (DRUJ) during forearm rotation. Since the proximal radius rotates about the capitellum of the humerus, while the distal radius rotates around the tip of the ulna, radius motion can be expressed in terms of translation along and rotation about a Helical Axis of Motion (HAM). The HAM notation therefore reduces the standard motion parameters (3 translations and 3 rotations) to one rotation and one translation. We will compare the mean (µ) and standard deviation (δ) of the healthy versus the affected forearm rotation. The main endpoint is to study whether we can differentiate between osseous (impinged) versus non-osseous (non-impinged) motion patterns as origin of restricted forearm rotation.
- Secondary Outcome Measures
Name Time Method Based on the patterns in inter-relational radioulnar motion pattern, the secondary aim is to develop a classification and assess the inter- and intra-observer reliability.<br /><br /><br><br>Furthermore to acquire knowledge of physiological mechanics of the radioulnar joint and to assess symmetry in radioulnar joint motions between two healthy forearms on 4D CT scans.
