- Original description
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.Read full original descriptionShow less

Inclusion: 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: 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; Surgeon concludes that eligible salvage techniques are not appropriate at the time of surgery (based on injury characteristics or concomitant wrist pathology); Participant has a physical or mental health condition preventing completion of consent or questionnaires; Participant has been diagnosed with other forms of wrist arthritis other than SLAC or SNAC; Participant does not speak/read/understand English; Participant has no fixed address or means of contact; Participant is unwilling to complete necessary follow-ups.
