3D MR Versus 3D CT for Glenohumeral Arthritis

Preoperative Magnetic Resonance as an Alternative to Computed Tomography Three-Dimensional Imaging for Characterizing Bone Loss in Shoulder Arthroplasty Candidates With Glenohumeral Osteoarthritis: A Prospective, Blinded, and Controlled Clinical Trial.

This study aims to assess the efficacy of three-dimensional magnetic resonance (MR) compared to three-dimensional computed tomography (CT) imaging. This proposed study is a prospective, unrandomized, single-blinded, self-controlled, and single-armed diagnostic radiological evaluation study.

Inclusion Criteria:

• Patients suffering from glenohumeral OA;
• Radiographic evidence of severe glenoid erosion;
• Indication for TSA based on clinical exam;
• Patient is willing to participate by complying with pre-operative visit requirements;
• Patient is willing and able to review and sign a study informed consent form.

Exclusion Criteria:

• Prior arthroplasty at the affected shoulder;
• Patients with inflammatory arthritis;
• Patients with post-capsulorrhaphy arthritis;
• Patients with post-traumatic arthritis;
• Patients with rotator cuff tear arthropathy;
• Patients exhibiting a lack of physical or mental ability to perform or comply with the study procedures;
• Patients who are pregnant;
• Patients with implanted medical devices that are contraindicated to exposure up to a 3.0-tesla magnetic field.
