Elbow Injury
Conditions
Brief summary
The objective of this retrospective and prospective consecutive series PMCF study is to collect long-term data confirming safety, performance and clinical benefits of the ExploR Radial Head System (implants and instrumentation) when used for radial head arthroplasty.
Detailed description
This is a global, multi-center, retrospective enrollment, prospective follow-up, consecutive series post-market clinical follow-up study. The intent of the study is that subjects who have already had the surgical implant will be retrospectively enrolled in the study and data will be collected for a minimum of 10 years post-operatively. Subjects treated with the device will be identified and invited to participate in the study. 93 subjects will be enrolled into the study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Device Survivorship | 10 years | Measured by recording and analyzing the incidence and frequency of revisions, complications and adverse events. Survivorship is calculated with Kaplan Meier. |
| Device Safety | 10 years | Assessed by recording frequency of adverse events during the length of the study. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| QuickDASH | 1, 3, 5, 7, and 10 years | QuickDASH measures musculoskeletal pain and function of the arm. Higher scores indicate higher severity of disability. |
