Comparing two techniques for wrist fusion in patients with post-traumatic arthritis

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

Run by University of Alberta · NCT04580225 · Data updated 2026-11-12

This study is testing two different surgery techniques for wrist fusion to see which one helps adults with post-traumatic arthritis feel better and regain more movement in their wrists.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with stage II or III SLAC or SNAC wrist arthritis who are surgical candidates for the specified interventions.

Probably not a fit

Patients with other forms of wrist arthritis or significant comorbidities affecting wrist function may not benefit from this study.

What this trial studies

This clinical trial compares the outcomes of two different partial wrist fusion techniques in adults suffering from post-traumatic wrist arthritis, specifically those with stage II or III scapholunate advanced collapse (SLAC) or scaphoid nonunion advanced collapse (SNAC). Participants will be randomly assigned to either a four-corner arthrodesis without triquetral excision or a three-corner/capitolunate arthrodesis with triquetral excision. The study aims to evaluate clinical and radiographic outcomes, including grip strength and wrist range of motion, through follow-up assessments conducted at multiple intervals post-surgery. The findings will help guide surgical decisions for optimal management of wrist arthritis.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and recovery for patients with post-traumatic wrist arthritis.

How similar studies have gone: Other studies have explored wrist fusion techniques, but this specific comparison of triquetral excision versus non-excision in partial wrist fusions is relatively novel.

Inclusion Criteria:

* Participant has a stage II or III scapholunate advanced collapse (SLAC) or scaphoid nonunion advanced collapse (SNAC) wrist and is a surgical candidate for the included surgical interventions

Exclusion Criteria:

* Participant has been diagnosed with other forms of wrist arthritis other than SLAC or SNAC
* Participant has significant arthritis of the ipsilateral hand/finger joint(s), major joint trauma, previous major wrist surgery, infection or neuromuscular pathology affecting the function of the ipsilateral upper extremity or ability to make a fist
* Participant has a physical or mental health condition preventing completion of consent or questionnaires
* Participant does not speak/read/understand English
* Participant has no fixed address or means of contact
* Participant is unwilling to complete necessary follow-ups
* Surgeon concludes that eligible salvage techniques are not appropriate at the time of surgery (based on injury characteristics or concomitant wrist pathology)
