Septic arthritis of the hip following cortisone injection: case report and review of the literature.

Septic arthritis of the hip is a serious medical condition that can result in permanent joint dysfunction. This is a case of a 65-year-old woman who underwent therapeutic intraarticular steroid/lidocaine injection for hip pain and subsequently developed septic arthritis. It is critical that radiologists performing these procedures maintain a high index of suspicion in symptomatic patients following intraarticular injections to prevent destruction of the joint.
