About this study

Official title: Comparison of Two Resurfacing Prostheses in the Treatment of Osteoarthritis of the Shoulder A Prospective, Randomized Migration and Bone Density Study

The purpose of this study is to determine whether there is a difference between the result of treatment of shoulder osteoarthritis with two different shoulder prostheses.

Read the detailed description

In this randomized study, we wish to investigate with the use of clinical and radiological parameters whether there is a difference between the result of treatment of shoulder osteoarthritis with the Copeland resurfacing prosthesis and the Global CAP resurfacing prosthesis.

Clinical parameters with the help of the Constant Shoulder Score (CSS) and Western Ontario Osteoarthritis of the Shoulder Index (WOOS):

  1. Pain
  2. Activities of Daily Living (ADL)
  3. Range of Motion (ROM)
  4. Muscle strength

Radiologic parameters:

  1. Migration of resurfacing prostheses with use of MB-RSA
  2. Bone density around the prosthesis measured with Dual Energy X-ray Absorptiometry (DEXA)
  3. Correlation between bone density and prosthesis migration
Conditions

What participants receive

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

  • Copeland or Global CAP resurfacing prosthesisProcedure or surgery

    Both Copeland and Global Cap are uncemented prostheses with titanium-sprayed, hydroxyapatite (HA)-coated bone-contact surfaces.

Questions about this trial

What is this clinical trial studying?

A study testing Copeland or Global CAP resurfacing prosthesis in people with Osteoarthritis, run by University of Aarhus at 2 sites in Denmark.

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 3 inclusion and 10 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: finished, as of the sponsor's last update on 16 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 2 sites in Denmark. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Migration of resurfacing prostheses (time frame: five years). The study lists 4 primary outcomes in all. 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 NCT00408096, which also lists 2 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 16 Aug 2018.
