Reports have emerged of local debris consisting of metal particles, with the development of pseudotumours, pelvic masses, lymphocytic perivascular infiltration of tissue around the implant and a neo-capsule tissue reaction in metal on metal (MoM) hip arthroplasty. Steeply-inclined acetabular components a large abduction angle of more than 55 degrees along with a combination of small size component are likely to give rise to higher levels of metal ions. This report describes a case of localised tissue destruction of abductor muscle probably due to the metal debris causing late onset subluxation/dislocation of a hip resurfacing. Late instability of hip resurfacing should raise concerns relating to possible local tissue reaction and muscle damage, and early revision may be recommended.
