Abstract
Infection is a devastating complication following total hip arthroplasty. For chronically infected total hip arthroplasty; we utilise a 2-stage articulating antibiotic hip spacer technique. Our success rate with the technique is 90% with patients clinically free of infection at an average of five years postoperatively. 80% of the patients had a positive identification of the infecting organism. The other 20% had a positive frozen section and clinically infected joints. All patients receive a minimum of 6 weeks of intravenous antibiotics. Postoperative hip scores average 90 points. Some patients elected to keep their antibiotic spacers for up to 2 years before the 2nd stage. Advantages of this technique include improved patient function, maintenance of bone stock and soft tissue tension, thus simplifying reimplantation.
