Randomized Comparison of PARtial Wrist Fusion With or Without Triquetral Excision (PARTE)

This randomized clinical trial (RCT) aims to compare clinical and radiographic outcomes of different partial wrist fusion techniques in participants with post-traumatic wrist arthritis. Participants with stage II or III scapholunate advanced collapse (SLAC) or scaphoid nonunion advanced collapse (SNAC) who meet the eligibility criteria will be randomly assigned to one of two parallel groups: Group A (partial wrist arthrodesis without triquetral excision i.e. four-corner arthrodesis), or Group B (partial wrist arthrodesis with triquetral excision i.e. three-corner or capitolunate arthrodesis with triquetral excision). The results of this study will provide evidence to guide surgeons in determining the ideal wrist fusion technique in the management of patients with post-traumatic wrist arthritis requiring surgery.
