About this study

Official title: A Prospective Cohort Study to Document the Clinical Outcomes in Shoulder Hemi-arthroplasty Using a PyC Spherical Interpositional Implant

The INSPYRE implant is a new range of shoulder hemi-arthroplasty device. It consists of a Pyrocarbon spherical interpositional implant and is indicated in primary surgery to relieve severe pain or significant disability caused by degenerative pathologies. The rotator cuff must be functional.

The aim of this study is to prospectively collect data from consecutive series to implement a Post Marketing Surveillance plan.

Read the detailed description

Degenerative shoulder pathologies associated with a functional rotator cuff are currently treated by hemi-arthroplasty or total prosthesis replacement. The choice of surgery process is mainly made according to the status of the glenoid.

Concerning hemi-arthroplasty, two types of humeral prosthesis are usually used: anatomical stems or resurfacing head implants. Both provide good results. Nevertheless with these prostheses, patient can present with post-operative pains due to glenoid erosion, linked to the metallic compounds used in such a prostheses. To face this issue, it was decided to modify the metallic compounds, and in order to mimic the tribological properties of the cartilage, Pyrocarbon (PyC) was found to be the best material.

First application of PyC in a medical device was for cardiac valves in 1969. Currently more than 2 million people live with PyC cardiac valves. Mechanical and physical properties of PyC are in favor of its use in orthopedic surgery; furthermore, its biocompatibility plays an important role in its good acceptability.

As very good results were observed when used in hand and wrist, interposition PyC implant was suggested for shoulder. Another advantage was that such interposition device allowed performing less invasive surgery, a particularly important criteria for young patients.

INSPYRE shoulder prosthesis was then designed as a shoulder interposition implant intended for partial replacement of the gleno-humeral joint. This implant is inserted between the glenoid cartilage and the humeral metaphyseal cavity. It is indicated in primary surgery to relieve severe pain or significant disability caused by degenerative pathologies, e.g., osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, primary and secondary necrosis of the humeral head. The rotator cuff must be functional.

What is being measured

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

  1. Implants survival rates

    Number of device or procedure related adverse events

    Measured: up to 10 years follow-up

Secondary outcomes (3)
  1. Change from baseline and previous visit in Constant Murley score

    Measured: at 1, 2, 5 and 10 years follow-up

  2. Change from baseline and previous visit in Range of Motion

    Forward flexion, Internal rotation and external rotation will be assessed

    Measured: at 3-6 months, 1, 2, 5 and 10 years follow-up

  3. Radiographic criteria timely evolution

    Glenoid erosion, tuberosities thinning, lateralization index, subacromial space and implant subsidence will be assessed according to available R-ray, CT or MRI

    Measured: at 3-6 months, 1, 2, 5 and 10 years follow-up

Questions about this trial

What is this clinical trial studying?

An observational study of Localized, Primary Osteoarthritis and Post-traumatic Arthrosis of Other Joints, Shoulder Region, run by Stryker Trauma and Extremities.

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 5 inclusion and 6 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 16 Apr 2019. 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?

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?

Implants survival rates (time frame: up to 10 years follow-up). 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 16 Apr 2019.
