Predictive Outcomes for Selective Thumb Carpometacarpal Joint Denervation
A study testing Wrist denervation procedure in people with CMC Arthritis, run by University of Calgary.
Trial summary
Background: The thumb (or first) carpometacarpal (CMC) joint is commonly affected by osteoarthritis. Literature has reported a prevalence of 15% in women and 7% in men. First CMC joint osteoarthritis can present with decreased grip strength, pain, instability and inability to engage in routine daily activities. Read more about this study

About this study
Background: The thumb (or first) carpometacarpal (CMC) joint is commonly affected by osteoarthritis. Literature has reported a prevalence of 15% in women and 7% in men. First CMC joint osteoarthritis can present with decreased grip strength, pain, instability and inability to engage in routine daily activities. Definitive management is with surgery, however these are associated with known risks and increased weight times for the patient. First CMC joint denervation surgery is supported in the literature as a safe and effective approach to treat pain, strength, and thumb opposition which still allows for definitive surgery to be performed later if the arthritis progressed or if the pain returned later after the surgery.
Objectives: (1) evaluate the effectiveness of the neurectomy in patients with with CMC arthritis with respect to pain relief, functional parameters, and Quick disabilities of the arm, shoulder and hand (QuickDASH) scores; (2) to determine whether pain relief with selective nerve blocks are predictive of the outcome of the combined neurectomy; and (3) to determine whether improvement in grip strength following selective blocks is predictive of final grip strength and outcome following neurectomy.
Methods: Patients referred to the plastic surgery clinic for assessment of symptomatic first CMC joint osteoarthritis will be provided options for standard treatment or denervation procedure. Patients who agree to denervation will undergo local anesthetic block at their initial consult. At their initial consultation as well as at the 2-week, 3-month, 6-month, 12-month and 24-month post-surgical follow-up, patients will complete a QuickDASH, Kapandji score, pain scores, 2-point discrimination and grip/key/3-point strength measurements. The total patient population included in this study will be 60 patients.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Wrist denervation procedureOther
To summarize, a Wagner incision is made starting over the junction of the glabrous and non-glabrous skin overlying the thumb CMC joint extending toward the distal wrist crease. The branches of the superficial radial nerve are identified as lying perpendicular to the plane overlying the fascia of the thenar muscles. The branches of the lateral antebrachial cutaneous nerve are identified and resected within the anatomic snuffbox deep to the first compartment. Finally, the thenar muscle fibers are divided at their proximal origin to identify the articular branches of the posterior cutaneous branch of the median nerve.
| Study group | Role | What they receive |
|---|---|---|
| Participants | Experimental | Patients with 1st CMC arthritis with Eaton stage 2 or 3 disease Receives: Other: Wrist denervation procedure |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pain outcomes from neurectomy
Participants will have their pre-operative pain scores compared to their post-operative denervation procedure evaluated with a QuickDASH questionnaire. This form will be completed at pre-operative visits and each follow-up appointment.
Measured: 2 years
Secondary outcomes (2)
Selective nerve block pain predictions
Number of participants with changes in pain with pre-operative selective nerve blocks evaluated on the Quick DASH questionnaire will be compared to the scores on the same questionnaire following the denervation procedure at each follow-up visit.
Measured: 2 years
Selective nerve block grip strength predictions
Participants will have grip strength measurements with pre-operative selective nerve blocks evaluated by the key-pinch and 3-point strength tests will be compared to the grip strength measurements at each follow-up visit following the denervation procedure on the same scale.
Measured: 2 years

Questions about this trial
What is this clinical trial studying?
A study testing Wrist denervation procedure in people with CMC Arthritis, run by University of Calgary.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 21 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Alexander Platt, MD (4036045130, alexander.platt@ucalgary.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pain outcomes from neurectomy (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06467669, which also lists 15 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jun 2024.
