Satisfactory Outcome for a Challenging Case of Infected Native Pelvic Discontinuity with Significant Bone Loss: A Case Report.

CASE: This is a challenging case of infected native pelvic discontinuity with massive acetabular bone loss. The infection was persistent despite repeated debridement. A new technique of articulated antibiotic spacer plus Mexican hat antibiotic spacer has been used. A triflanged custom-made implant was used in the second-stage surgery. The 2-year follow-up showed no recurrence of infection and no loosening. CONCLUSION: Using a Mexican hat spacer is a good option when there is a massive bone loss medially. Custom-made triflanged cup showed to be a viable treatment modality for infected pelvic discontinuity despite the cost of the implant.
