The Nuffield Orthopaedic Centre in Oxford have published a study on a clinical trial concerning a number of patients who had received metal on metal resurfacing, who has various symptoms and a pseudotumour (these are non malignant).

This study showed that the most common symptom was discomfort in the hip whereas other symptoms included spontaneous dislocation, nerve palsy (a collective term for a range of nervous disorders that result in weakness or immobility of nerves in some region of the body) a noticeable mass or a rash.

If you have received a DePuy ASR hip resurfacing system or any other metal on metal hip resurfacing system please contact the product liability team at Garden House Solicitors by telephone - 01992 422 128 or by email – .

Those who conducted this clinical trial estimated that approximately 1% of patients who have a metal on metal resurfacing system develop a pseudotumour within 5 years post implantation.

However, DePuy have established that approximately 12% of patients who have received the DePuy ASR resurfacing device and 13% of patients who have received the DePuy ASR total hip replacement have needed revision surgery within 5 years post implantation.

Those who have received a DePuy ASR hip implant since July 2003 should seek medical advice to confirm whether their hip implant is functioning correctly and they should contact Kevin Timms within the product liability team at Garden House Solicitors to discuss whether they are entitled to make a claim for compensation.
