MDR - PMCF Study for Echo FX Stem With RingLoc Bipolar Acetabular Cup and Femoral Head

Study Overview
=================
Brief Summary
-----------------
The objective of this retrospective enrollment and prospective follow-up study is to confirm safety, performance, and clinical benefits of the Echo FX Stem with the RingLoc Bipolar Acetabular Cup and Femoral Head in hip hemiarthroplasty (implants and instrumentation) at a minimum of 10 years follow-up. All available retrospective data will be collected from each patient and a prospective aspect to the study will be necessary to reach the 10-year time point.

Detailed Description
-----------------
The objective of this retrospective enrollment and prospective follow-up study is to confirm safety, performance, and clinical benefits of the Echo FX Stem with the RingLoc Bipolar Acetabular Cup and Femoral Head in hip hemiarthroplasty (implants and instrumentation) at a minimum of 10 years follow-up. All available retrospective data will be collected from each patient and a prospective aspect to the study will be necessary to reach the 10-year time point. The primary objective is to confirm the safety of the implants. This will be assessed by recording and analyzing the incidence and frequency of revisions, complications and adverse events. Relationship of the events to either implant or instrumentation will be specified. The secondary objective is the assessment of performance and clinical benefits by analyzing recorded Patient Reported Outcomes Measures (PROMs).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Device safety assessed through the frequency and incidence of revisions, complications, and Adverse Events. | The primary objective of this study is the assessment of safety by analyzing implant survivorship. This will be established by recording the incidence and frequency of revisions, complications, and Adverse Events. Relation of the events to either implant or instrumentation will be specified. | Out to 10 years. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Device Performance and Benefits evaluated through the Oxford Hip Score. | The OHS is a patient-completed, 12-question evaluation. Each item is scored from 1 to 5, with 1 representing best outcome/least symptoms and 5 representing worst outcome/most symptoms. | Out to 10 years. |
