European Review for Medical and Pharmacological Sciences Fast growing pseudotumour in a hairdresser after metal-on-metal hip resurfacing: a case report

Corresponding Author: Eugenio Chiarello, MD; e-mail: [email protected] the occurrence of abnormal soft tissue reactions, sometimes called pseudotumours, following MOMHR5-9. However, the exact biological pathway that leads to the local effects seen in MOMHR hips remains unclear10. We report a particular case of pseudotumour formation after MOMHR in a female who previously worked as an hairdresser. To investigate occupational exposure to metals prior to prosthetic surgery in order to limit pseudotumour risk is clinically relevant both for patients and surgeons. Moreover, clarifying the pseudotumour pathogenesis would increase the safety of metal-based implants.
