COMPLETE BONE REMODELING AFTER CALCAR RECONSTRUCTION WITH METAL WIRE MESH AND IMPACTION BONE GRAFTING: A CASE REPORT

We report the histological findings of a reconstructed calcar region four years after femoral impaction bone grafting using metal wire mesh for a case with massive defect of the proximal part of the femur. Thin cortical bone was formed just beneath the metal wire mesh and viable trabecular bone containing a small amount of granulation tissue was observed even at the bone-cement interface. Almost no necrotic bone was seen throughout the remodeled bony layer. Histological findings of the present case suggest that calcar reconstruction with impaction bone grafting using a metal wire mesh is a biologically and mechanically favorable reconstruction method for femoral revision cases combined with proximal medial segmental cortex defect.
