As the incidence of metal-on-metal hip resurfacing has increased in recent years, especially in younger patients, research published in the Journal of Bone and Joint Surgery - British Volume (JBJS-Br) discusses occurrences of "pseudotumours" as a result.

The researchers estimate that approximately 1% of patients who have metal-on-metal hip resurfacings develop pseudotumours within five years of treatment. A pseudotumour is 'a soft-tissue mass associated with the implant…neither malignant nor infective in nature', but that causes pain and discomfort to the patient.

Most worryingly for patients and doctors is that the causes of the tumours are unknown. The research discusses possible causes including 'toxic reaction to an excess of particulate metal wear debris.' The article stresses the need for further research to be done into the incidence of pseudotumours in patients who have had this treatment.

The paper concludes that the incidence of pseudotumours must be related to metal-on-metal hip resurfacing highlighting 'the need for regular clinical follow-up for new devices'. Such follow-up would follow NICE recommendations, but the current NHS climate makes this difficult, if not impossible, to achieve.
