Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoint is defined as the postoperative SL distance at the time of examination at least 6 months after surgery. The measurement is performed using static and dynamic X-ray images with the XERO viewer by Agfa Healthcare in a side-by-side comparison (provided that the other hand is unaffected) and otherwise using the standard values of less than 3.1 mm described in the literature. (Kuru CA, Sezer R, Çetin C, Haberal B, Yakut Y, Kuru I. Use of Generalizability Theory Evaluating Comparative Reliability of the Scapholunate Interval Measurement With X-ray, CT, and US. Acad Radiol. 2023 Oct;30(10):2290-2298.) | — |
Secondary
| Measure | Time frame |
|---|---|
| The wrist mobility of the affected wrist in flexion, extension, radial and ulnar deviation is determined at the time of examination (at least 6 months after surgery) using a goniometer and the neutral zero method. Grip strength compared to the unaffected hand is determined at the time of examination (at least 6 months after surgery) using a dynamometer in three measurements per hand. In addition to the primary endpoint of SL distance, the SL angle, RL angle and the presence of signs of osteoarthritis are also measured or described at the time of examination (at least 6 months after surgery) using the corresponding X-ray images. Functional limitations in everyday life due to the hand injury and general quality of life are determined at the time of examination (at least 6 months after surgery) using the corresponding questionnaires (DASH & PRWE for hand function, SF-36 for general quality of life). Pain sensations at rest and when stressing the wrist are determined at the time of examination (at least 6 months after surgery) using the VAS. Other injury-related complaints are recorded as notes at the time of examination (at least 6 months after surgery) in order to better classify the patient's overall picture. | — |
