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.

Lunatocapitate Fusion Versus Four-corner Fusion for SNAC and SLAC Arthritis.

Hypothesis: Lunate-capitate-fusion (LCF) results in comparable outcome (i.e. not worse) to four-corner-fusion (4CF) for Scaphoid Nonunion Advanced Collapse (SNAC) and Scapholunate Advanced Collapse (SLAC) arthritis regarding functional results (grip strength). Design: Prospective randomised comparison. Inclusion criteria: SNAC or SLAC arthritis requiring a salvage procedure (grade 2-3). Exclusion criteria: SNAC or SLAC arthritis grade 4 (panarthritis). Inability to co-operate with the follow-up protocol (language difficulties, severe psychiatric disorder or drug addiction).
