Completed

Conditions: Revision
Fracture
Avascular Necrosis
Osteoarthritis Shoulder
Rheumatoid Arthritis
Rotator Cuff Tear

Interventions: Device: TESS V2

Registration Number: NCT03431857

Lead Sponsor: Zimmer Biomet

Brief Summary: This study is a Post Market Clinical Follow-up study to fulfill the post market surveillance requirements. The data collected from this study will serve the purpose of confirming safety and performance of the TESS Shoulder System.

Detailed Description: The objective of this retrospective and prospective, multicenter, non-controlled Post Market Clinical Follow-up study is to evaluate the mid-term (5-year) clinical performance of the TESS Version 2 Anatomic and Reverse prostheses in shoulder arthroplasty. The primary outcome is defined as the clinical performance determined using Constant Score. The secondary outcomes are the passive and active mobility, the radiographic evaluation, the complications (including dislocation and revisions/removals) and survivorship.

Recruitment & Eligibility

Status: COMPLETED

Sex: All

Target Recruitment: 106

Inclusion Criteria

Except in special cases, the "anatomic" type is indicated for:
- Centered osteoarthritis of the shoulder
- Humeral head fractures
- Rheumatoid arthritis (with intact rotator cuff)
- Avascular necrosis of the humeral head
Except in special cases, the "reversed" type is indicated for:
- Offset osteoarthritis of the shoulder
- Massive and non-repairable rotator cuff tears
- Rheumatoid arthritis (with degenerative rotator cuff)
Revision in cases of:
- Replacement of an "anatomic" prosthesis with a "reversed" prosthesis
- Conversion of a hemi-arthroplasty into a total arthroplasty
- Increasing the size of the stem (length and/or diameter)
- Replacing a glenoid prosthesis
- Replacing a competitor's prosthesis
- In rare cases, removing a "reversed" prosthesis and replacing it with an "anatomic" prosthesis
Additional inclusion criteria include
- Patient who read, understood study information and gave informed consent (oral or written depending on specific local regulatory requirements)
- Willing to return for follow-up evaluations

Exclusion Criteria

Local or systemic infections.
Severe muscular, neurological, or vascular deficiency of the affected joint.
Bone destruction or poor bone quality liable to affect the stability of the implant (Paget's disease, osteoporosis, etc.)
Cases where the corolla cannot be two-thirds covered with bone stock and including the stem/corolla junction.
Any concomitant complaint likely to affect the functioning of the implant.
Allergy to any of the implant components.
Local bone tumors.
Patient over 18 under law supervision

Group	Intervention	Description
TESS V2 Prosthesis	TESS V2	Single study patient cohort, including 106 patients who meet the inclusion/exclusion criteria and who received the TESS V2 shoulder prosthesis.

Primary Outcome Measures

Name	Time	Method
Constant Shoulder Score	Pre-operative, 5 years follow-up	The Constant Murley score is a multi-item scale assessing the level of pain and the ability to carry out the normal daily activities of the patient. The test is divided into four subscales: pain (0-15 points), activities of daily living (0-20 points), strength (0-25 points) and range of motion: forward elevation, external rotation, abduction and internal rotation of the shoulder (0-40 points). The results are here reported as final score, which ranges from 0 to 100, with 0 representing the worst and 100 the best shoulder function.

Secondary Outcome Measures

Name	Time	Method
Active External Rotation RE1	Pre-operative, 5 years follow-up	The active mobility is measured with 4 movements: active anterior elevation, active lateral elevation, external rotation elbow to body (RE 1) and external shoulder rotation in abduction at 90° (RE 2). Active external rotation RE1 measures the extent to which a patient can rotate the bent arm externally and is here reported in degrees.
Passive Elevation	Pre-operative, 5 years follow-up	The passive mobility is measured with 2 movements: elevation and external rotation elbow to body (RE 1). Passive elevation measures the extent to which the arm of the patient can be passively elevated in the plane of the scapula and is here reported in degrees.
Radiographic Evaluation	Immediate post-operative, 6 weeks follow-up, 6 months follow-up, 1 year follow-up, 2 years follow-up, 3 years follow-up, 4 years follow-up, 5 years follow-up.	A complete radiographic evaluation (front view 3 rotations, lateral view) is completed pre-operatively. For the post-operative radiographic evaluations, the form is simplified and contains two options: "unchanged" or "changed" when compared to the preoperative x-ray, with presence of radiolucencies and/or notching. The number of "changed" radiographic evaluations per time point are here reported.
Active Anterior Elevation	Pre-operative, 5 years follow-up	The active mobility is measured with 4 movements: active anterior elevation, active lateral elevation, external rotation elbow to body (RE 1) and external shoulder rotation in abduction at 90° (RE 2). Active anterior elevation measures the extent to which a patient can elevate the arm anteriorly and is here reported in degrees.
Active External Rotation RE2	Pre-operative, 5 years follow-up	The active mobility is measured with 4 movements: active anterior elevation, active lateral elevation, external rotation elbow to body (RE 1) and external shoulder rotation in abduction at 90° (RE 2). Active external rotation RE2 measures the extent to which a patient can rotate the arm externally from a position of 90° of abduction and is here reported in degrees.
Active Lateral Elevation	Pre-operative, 5 years follow-up	The active mobility is measured with 4 movements: active anterior elevation, active lateral elevation, external rotation elbow to body (RE 1) and external shoulder rotation in abduction at 90° (RE 2). Active lateral elevation measures the extent to which a patient can elevate the arm laterally and is here reported in degrees.
Passive External Rotation	Pre-operative, 5 years follow-up	The passive mobility is measured with 2 movements: elevation and external rotation elbow to body (RE 1). Passive external rotation elbow to body (RE 1) measures the extent to which the bent arm of the patient can be passively rotated externally and is here reported in degrees.
Survivorship	5 years follow-up	The Kaplan-Meier method is used to report implant survivorship. This outcome measures survivorship of the implanted devices from the date of implantation to the date of revision or intended revision up to 5 years post-operatively.
