This case involves a female patient who underwent a total hip replacement in order to repair a serious injury to her right hip. Post-operatively, the patient developed foot drop which was not present prior to the operation. She also complained of a burning sensation in the lower part of the left leg extending down into the rear surface of the foot. She was discharged and asked to follow-up a few days later, at which point symptoms were expected to resolve. Over a year later, however, her condition had not improved.
