NCT04580225

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Grip Strength

    Peak grip strength will be assessed using a hand-held dynamometer. Grip strength will be compared between groups over the 12-month evaluation period.

    Completed at baseline (pre-surgery), 3-, 6-, 12-months post-surgery

Secondary Outcomes (7)

  • Wrist Range of Motion (ROM)

    Baseline, 3-, 6-, 12-months post-surgery

  • Patient-Reported Outcomes Measurement Information System® (PROMIS)

    Baseline, 6-weeks, 3-, 6-, 12-months post-surgery

  • Patient-Rated Wrist Evaluation (PRWE) Questionnaire

    Baseline, 6-weeks, 3-, 6-, 12-months post-surgery

  • Visual Analog Scale (VAS) Pain Score

    Baseline, 6-weeks, 3-, 6-, 12-months post-surgery

  • Complications

    6-weeks, 3-, 6-, 12-months post-surgery

  • +2 more secondary outcomes

Study Arms (2)

Group A: Partial Wrist Arthrodesis without Triquetral Excision

ACTIVE COMPARATOR

Group A: Partial Wrist Arthrodesis without Triquetral Excision

Participants in Group B will receive a three-corner arthrodesis (fusion of the capitate, hamate, and lunate) or capitolunate arthrodesis (fusion of the capitate and lunate) with excision of the scaphoid and triquetrum.

Group B: Partial Wrist Arthrodesis with Triquetral Excision

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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

You may not qualify if:

  • 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)
