Is this trial a fit for you?

Likely a good fit

Adults with displaced intracapsular hip fractures (Garden III-IV) who underwent bipolar hemiarthroplasty with the CoCrMo LOCK bipolar head since January 2023 and can ambulate preoperatively.

Probably not a fit

Patients with undisplaced fractures, cognitive impairment severe enough to fail screening, or contraindications to the device may not benefit.

What this trial studies

This is a monocentric, retrospective observational study designed to assess safety and performance of CoCrMo LOCK bipolar femoral heads used in hemiarthroplasty. Patients treated from January 1, 2023 onward are followed for two years with data collected at pre-op, intra-op, discharge, and at 4, 12, and 24 months. Outcomes include revision rate, dislocation, radiographic assessments, patient-reported outcomes, and walking/residential status. The analysis will compare observed event rates to the expected performance per the device's indication for use. The goal is to confirm device safety and functional performance in real-world use after market release.

Why it matters

Potential benefit: If successful, the study could support continued use of the CoCrMo LOCK bipolar head with improved confidence in safety and functional outcomes for patients requiring hemiarthroplasty.

How similar studies have gone: Previous studies on similar hemiarthroplasty components have shown variable safety signals; this study adds real-world post-market data for this specific head design.
