About this study

Official title: Clinical, Radiological and Patient Perceived Outcome After Total Wrist Arthroplasty With a New Total Wrist Arthroplasty Implant

Total wrist arthroplasty (TWA) surgery has developed gradually and can offer patients with rheumatoid arthritis/osteoarthritis reduced wrist pain with mainly preserved wrist range of movement. Each year 60-70 patients in Sweden are operated with a total wrist arthroplasty. Several implants are available on the market and they all have different pros and cons. One risk with a total wrist arthroplasty is loosening of the implant. If an implant is loose, revision of the implant to another TWA is sometimes possible, if not, a wrist fusion is the likely alternative. Revision rates five years after the index operation have improved, however, they cannot yet compare with the results after a total hip arthroplasty. A newly designed TWA has been developed by the department of Hand Surgery, Örebro university Hospital, Örebro, Sweden, in cooperation with Trimed Inc. The newly developed TWA offers theoretical advantages and has been biomechanically tested at the Mayo clinic.

This is a pilot study where patients operated with the TWA will be assessed pre and postoperatively according to study protocol in order to evaluate outcome after TWA radiologically, clinically and regarding patient perceived outcome measures.

Read the detailed description

Method: Patients will be studied preoperatively and after 1, 2, 5, and 10 years with respect to changes of the following outcome measures.

  1. Patient related outcome measures: DASH=Disabilities of Arm Shoulder and Hand, COPM=Canadian Occupational Performance Measure, PRWE=Patient Related Wrist Evaluation.
  2. Wrist range of motion: dorsal/volar flexion, ulnar/radial deviation, pronation/supination. Hand grip strength, pinch grip, key pinch.
  3. Wrist pain. VAS-pain scores (Visual analog score) at rest and in activity.
  4. X-ray findings. Implant survival will be studied with Kaplan-Meyer graphs.

What is being measured

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

  1. revision rate

    The frequency of TWA implants revised up to 10 years after the index operation

    Measured: changes in revision rates up to 10 years postoperatively

Secondary outcomes (2)
  1. changes in patient related outcome measures (PROM)

    Assessed as DASH=Disabilities of Arm Shoulder and Hand, COPM=Canadian Occupational Performance Measure, PRWE=Patient Related Wrist Evaluation preoperatively and after 1, 2, 5, and 10 years postoperatively

    Measured: 1, 2, 5, and 10 years postoperatively

  2. Changes in Range of Motion (ROM

    flexion, extension, radial and ulnar deviation, pronation, supination. Hand grip strength, pinch grip, lateral grip, and radiographic loosening, VAS-pain scores.

    Measured: 1, 2, 5, and 10 years postoperatively

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing total wrist arthroplasty, Trimed in people with Rheumatoid Arthritis and Osteoarthritis, run by Örebro University, Sweden at 1 site in Sweden.

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 29 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Sweden. 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.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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 Kurt Pettersson, MD, PhD (0046196025190, kurt.pettersson@orebroll.se), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

revision rate (time frame: changes in revision rates up to 10 years postoperatively). 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 29 Aug 2018.
