Trial summary

Rationale: The trapeziometacarpal (TMC) joint is one of the most common areas in the hand and wrist to develop osteoarthritis (OA). Currently, the two most widely used procedures are the trapeziectomy and the TMC-joint arthroplasty, both with their own pros and cons. Read more about this study

About this study

Rationale: The trapeziometacarpal (TMC) joint is one of the most common areas in the hand and wrist to develop osteoarthritis (OA). Currently, the two most widely used procedures are the trapeziectomy and the TMC-joint arthroplasty, both with their own pros and cons. No studies have demonstrated superiority of TMC-joint arthroplasty over gold-standard trapeziectomy. And no clinical studies show short-term recovery and patient experience after trapeziectomy or TMC-joint arthroplasty.

Objective: To gather insight in short-term recovery and patient experience after a trapeziectomy or TMC prosthesis regarding pain, pain medication, function and quality of life.

Study design: A prospective observational cohort diary study.

Study population: In total 200 subjects with TMC-joint osteoarthritis will participate: 100 subjects will have trapeziectomy and 100 subjects will have TMC-joint arthroplasty

Main study parameters/endpoints: The main study parameters are the pain, function and quality of life during the first 8 weeks after surgery.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Subjects will have no direct benefit from participation in this study. Subjects will only complete a diary and questionnaires for this study. Therefore, we expect no risks from participation. The burden for subjects consists of approximately five minutes daily for the diary in the first eight weeks after surgery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT06654349
Study groupRoleWhat they receive
TrapeziectomyThis cohort consist of patients receiving a trapeziectomy for arthrosis of the first carpometacarpal joint. The cohort will include 100 patients
TMC-arthroplastyThis cohort consist of patients receiving TMC-arthroplasty for arthrosis of the first carpometacarpal joint. The cohort will include 100 patients

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pain

    Pain will be measured each day in a diary for the first 8 weeks after surgery with the Numeric Rating Scale for Pain (NRS), which is a scale ranging from zero to ten on which patients can score their pain. It is a widely used instrument in varying populations due to its ease of administration and clinical relevance to the subject.

    Measured: 8 weeks

  2. Function

    Function will be measured each week in a diary for the first 8 weeks after surgery with the The Patient-Related Wrist/Hand Evaluation (PRWHE), which is a 15-item questionnaire concerning pain and function. Subjects are able to rate their pain and disabilities from zero to ten.

    Measured: 8 weeks

  3. Quality of life (QoL)

    QoL will be measured twice a week in a diary for the first 8 weeks after surgery with the EQ-5D, which is a general health-related quality-of-life questionnaire and consists of five questions regarding mobility, self-care, usual activities, pain/discomfort and anxiety/depression and one visual analog scale (VAS) to document the perceived quality of life. It is also used to assess quality of life adjusted life years (QALY).

    Measured: 8 weeks

Secondary outcomes (6)
  1. Complications

    Complications will be measured in the number of complications.

    Measured: 1 year

  2. Pain medication

    Pain medication will be measured with a diary during the first 8 weeks after surgery

    Measured: 8 weeks

  3. PROMs - NRS

    Patient-related outcome measurements (PROMs) will be measured with the NRS as part of the standard care. Numeric Rating Scale for Pain (NRS) is a scale ranging from zero to ten on which patients can score their pain. It is a widely used instrument in varying populations due to its ease of administration and clinical relevance to the subject.

    Measured: 1 year

  4. PROMs - PRWHE

    Patient-related outcome measurements (PROMs) will be measured with the PRWHE as part of the standard care. The Patient-Related Wrist/Hand Evaluation (PRWHE) is a 15-item questionnaire concerning pain and function. Subjects are able to rate their pain and disabilities from zero to ten.

    Measured: 1 year

  5. PROMs - EQ5D

    Patient-related outcome measurements (PROMs) will be measured with the EQ5D as part of the standard care. EQ-5D is a general health-related quality-of-life questionnaire and consists of five questions regarding mobility, self-care, usual activities, pain/discomfort and anxiety/depression and one visual analog scale (VAS) to document the perceived quality of life. It is also used to assess quality of life adjusted life years (QALY). It has been translated into Dutch and validated in different populations.

    Measured: 1 year

  6. PROMs - HADS

    Patient-related outcome measurements (PROMs) will be measured with the HADS as part of the standard care. The Hospital Anxiety and Depression Scale (HADS) is a 14-item questionnaire concerning the mental state of the subject (i.e. anxiety and depression).

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Arthrosis of First Carpometacarpal Joint, run by Reinier Haga Orthopedisch Centrum at 1 site in Netherlands.

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 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Rianne Oomen (+31792065595, Onderzoek@rhoc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain (time frame: 8 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 May 2025.
