Trial summary

The hypothesis is that computer simulated bony impingement of the bone surrounding the spherical glenoid implant (the glenosphere) along the scapular neck on three-dimensional (3-D) computed tomography (CT) imaging analysis is predictive of the location of clinical scapular notching that develops following reverse… Read more about this study

About this study

Official title: Prediction of Development of Scapular Notching Based on Glenosphere Positioning, Scapular Morphology, and Simulated Impingement-free Motion Using Three-dimensional Computed Tomography Analysis

The hypothesis is that computer simulated bony impingement of the bone surrounding the spherical glenoid implant (the glenosphere) along the scapular neck on three-dimensional (3-D) computed tomography (CT) imaging analysis is predictive of the location of clinical scapular notching that develops following reverse total shoulder arthroplasty (TSA).

Read the detailed description

The Specific Aims are:

  • Determine the relationship between lateral glenoid offset and the development of scapular notching following reverse TSA
  • Determine the ability of 3-D preoperative planning tools to define areas of scapular bony impingement on kinematic simulated shoulder range of motion that predict the development of scapular notching
  • Compare the precision and accuracy of plain radiographs (2-D) versus CT (3-D) for measurement of scapular notching and postoperative implant position following reverse TSA (2-D versus 3-D)
  • Determine the implant and anatomic factors that best correlate with clinical outcome following reverse TSA by retrospective analysis

What is being measured

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

  1. Actual Versus Predicted Scapular Notching

    At minimum 2 year follow-up, compare presence of scapular notching as assessed by 2D x-ray and 3D CT imaging with predicted scapular notching as assessed by 3D computer modeling using video motion analysis of subject range of motion.

    Measured: At least 24 months after reverse TSA

Secondary outcomes (11)
  1. Patient Reported Pain, Satisfaction and Function (Penn Shoulder Score)

    The Penn Shoulder Score is a shoulder-specific patient reported outcome measure. Best possible score is 100; worst possible score is 0. There are 3 sub-scores: pain (3 questions, 30 possible points), satisfaction (1 question, 10 possible points), and function (20 questions, 60 possible points). Total score is the sum of the 3 sub-scores. For all sub-scores, higher is better.

    The pain questions are based on a 10-point numeric rating scale. Points are added for the pain sub-score.

    The satisfaction question asks the patient to rate their satisfaction with their shoulder. It is based on a 10-point numeric rating scale, with 0 as "not satisfied" and 10 as "very satisfied".

    The function sub-score has 20 questions concerning activities of daily living. The response options are: 0 (can't do at all), 1 (can do with much difficulty), 2 (can do with some difficulty) and 3 (can do with no difficulty). If all activities can be done without difficulty, a score of 60 is achieved.

    Measured: At least 24 months after reverse TSA

  2. Shoulder Strength - Flexion

    Muscle strength test will be performed three times with each motion and recorded, using the Lafayette Manual Muscle Test System (Model # 01163). Units of output are pounds.

    Measured: At least 24 months after TSA

  3. Shoulder Strength - Abduction

    Muscle strength test will be performed three times with each motion and recorded, using the Lafayette Manual Muscle Test System (Model # 01163). Units of output are pounds.

    Measured: At least 24 months after TSA

  4. Shoulder Strength - Internal Rotation

    Muscle strength test will be performed three times with each motion and recorded, using the Lafayette Manual Muscle Test System (Model # 01163). Units of output are pounds.

    Measured: At least 24 months after TSA

  5. Shoulder Strength - External Rotation

    Muscle strength test will be performed three times with each motion and recorded, using the Lafayette Manual Muscle Test System (Model # 01163). Units of output are pounds.

    Measured: At least 24 months after TSA

Questions about this trial

What is this clinical trial studying?

An observational study of Osteoarthritis and Rotator Cuff Tear Arthropathy, run by Eric Ricchetti at 1 site in United States.

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 1 inclusion and 1 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 9 May 2017. 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 United States. 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?

Yes. Results are posted in the registry (first posted 23 Feb 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Actual Versus Predicted Scapular Notching (time frame: At least 24 months after reverse TSA). 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 NCT02052466, which also lists 1 linked publication.

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 9 May 2017.
