A Custom Trabecular Metal Implant in Revision Total Hip Replacement with a Paprosky Type-IV Femoral Defect: A Case Report.

Overview

CASE: Treatment for severe femoral bone defects involving loss of the supporting isthmus is limited. Techniques are based on surgeon experience and patient-related factors. Revision arthroplasty can be challenging depending on bone loss and quality. Highly porous metals, such as trabecular metal, are ideal alternatives for complex reconstruction; however, little has been written about trabecular metal for reconstruction of the proximal part of the femur. CONCLUSION: We report the five-year midterm results of a custom trabecular metal implant for a Paprosky type-IV femoral defect. This novel construct provides durable midterm survivorship and excellent function for Paprosky type-IV femoral bone loss.
