hi. I had an oestoid oesteoma removed from neck of femur 25 years ago. i fractured femur post op and a pin and plate were put in, as well as a broken drill bit. a year later hardware was removed except for drill bit. 25 yrs on, pain has returned with activity and site is painful to touch. On xray theres a black shadow round drill bit and raised thicker bone. im having scan for possible infection. anyone heard of this and whether its wise to remove bit to treat infection? or any other info. i realise its not hip replacement but having hard time finding any info.
