Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Male or female; age between 18 and 75 years.
  • Patient with symptomatic STT OA.
  • Patient treated medically for functional signs for more than 3 months, without improvement, justifying a surgical intervention.
  • Patient with a QuickDash score > 33 points (converted to 50%).
  • Patient with wrist pain in front of the STT joint at rest = or > 4/10 on VAS.
  • Patient who received the study information and provided consent.
  • Member or beneficiary of a national health insurance plan.

Exclusion criteria

Exclusion Criteria:

  • Pregnant or breastfeeding woman; woman without effective .
  • Patient with functional rhizarthrosis that has not been stabilized or treated medically or surgically.
  • Patient with signs of neuropathy with functional disorders such as hyperesthesia.
  • Patient with uncontrolled epilepsy or neuropathy that contraindicates locoregional anesthesia.
  • Person confined by a judicial or administrative decision.
  • Adult subjected to legal protection measures or unable to provide his/her consent.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. Decrease of the symptomatology related to the STT OA

    Quality of life related to STT OA evaluated using Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire (0 = no disability, 100 = most severe disability); a decrease of 25% of the score is expected between subject's inclusion and the 12-month postoperative visit

    Time frame: 12 months

Secondary outcomes

  1. Absence of inflammatory reactions and good local tolerance of the implant

    No inflammatory reactions (oedema, erythema, necrosis, ulceration and/or delayed wound healing), no adverse effects or serious adverse effects.

    Time frame: Through study completion (12 months)

  2. Decrease of pain related to STT OA

    Pain evaluated from 0 (no pain) to 10 (worst imaginable pain) on a visual analog scale (VAS)

    Time frame: 1 month, 3 months, 6 months, 12 months

  3. Improvement of functional activities involving the thumb

    Functional activities involving the thumb evaluated from 0 (best) to 56 (worst) using the Buffet score developed by the Besançon University Hospital

    Time frame: 1 month, 3 months, 6 months, 12 months

  4. Increase of thumb strength

    Thumb strength measured in kg by two-point pinch strength test using a pinch gauge

    Time frame: 3 months, 6 months, 12 months

  5. Increase of grip strength

    Grip strength measured in kg by grip strength test using a dynamometer

    Time frame: 3 months, 6 months, 12 months

  6. No apparent joint space anomaly

    Joint space evaluated on radiography using Crosby's classification

    Time frame: 12 months

ElapsedEstimatedEstimated, not yet reachedDate before it movedWhere the date was before it movedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2024 (actual). Primary completion is estimated for Nov 2026, 30 months after the start.

Of 54 industry-sponsored phase 2 interventional studies under Osteoarthritis, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 32. This study's planned 30 months is above that.

Counting every sponsor, half of 82 studies reached it within 19 months; a quarter within 10 and three quarters within 38.

Since we started tracking on Sep 25, 2026, the dates moved once, on Oct 6, 2026: primary completion Dec 2026 → Nov 2026 and completion Dec 2026 → Nov 2026.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
