Investigating hearing loss in patients with metal-on-metal hip implants

Ototixicity in Patients With a Metal-on-Metal Hip Arthroplasty

Observational Reinier Haga Orthopedisch Centrum · NCT06885411

This study is testing whether people with metal-on-metal hip implants experience hearing loss due to metal exposure in their blood.

What this trial studies

This observational study aims to assess the prevalence of hearing loss in patients who have undergone metal-on-metal (MoM) hip arthroplasty. It will evaluate the relationship between plasma metal concentrations, specifically cobalt and chromium, and the incidence of ototoxicity. The study will involve patients from various clinics who have received MoM implants, focusing on their auditory health and potential complications related to metal exposure. Participants will be monitored for their hearing capabilities and metal levels in their blood.

Who should consider this trial

Good fit: Ideal candidates for this study are patients who have received metal-on-metal hip implants and are willing to participate while being proficient in the Dutch language.

Not a fit: Patients who have had previous ENT surgery or have existing ENT pathology may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the risks of hearing loss associated with metal-on-metal hip implants, leading to better patient management and device selection.

How similar studies have performed: While there have been studies on metal-on-metal implants, the specific focus on ototoxicity and its correlation with plasma metal concentrations is relatively novel.
