Background: Two-stage reconstruction is a well-recognized treatment for deep infection of hip joint implants. The purpose of the study was to report the results of our treatment using a standardized protocol.
Methods: Forty-two consecutive patients with deep infection of the hip prosthesis were treated according to a prospective, two-stage resection/reimplantation protocol. Between stages, a custom-made, antibiotic-loaded, cement prosthesis was implanted as an interim spacer.
Results: Infection was eradicated in 41 patients after the first-stage operation. Thirty-six patients remained with the ability to walk with the interim cement pros-thesis. For 40 patients who underwent reimplantation, recurrence of infection was observed in only 1 patient at an average of 55.2 months' follow-up.
Conclusion: We have found that our two-stage treatment protocol is a reliable approach for the management of infected hip prostheses. It is effective for eradicating infection and for providing a mobile and functional joint through the treatment course.
