Design outcomes
Primary
| Measure | Time frame |
|---|---|
| As an uninjured radius normally rotates +/- 180 degrees around the ulna at the distal radioulnar joint (DRUJ), the aim is to estimate the pattern of restricted motion of the posttraumatic (malunited) radius relative to the ulna, expressed in rotation at the level of the DRUJ. 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
| Measure | Time frame |
|---|---|
| Based on the patterns in inter-relational radioulnar motion pattern, the secondary aim is to develop a 4D classification tool for posttraumatic impairment of the forearm and to assess its inter- and intra-observer reliability. Futhermore to assess physiological mechanics of the radioulnar joint and symmetry in motion patterns between two healthy forearms on 4D CT scans. | — |
