Structural Allograft and Induced Membrane Technique for Treatment of 10-cm Segmental Femoral Bone Defect: A Case...

A modified induced membrane technique for the treatment of a posttraumatic 10-cm infected segmental femoral defect is reported. The first stage involved debridement and insertion of an antibiotic cement spacer and 2 Ender nails. Reconstruction was performed with a 14-cm structural bone allograft, inverted and telescoped into both ends of the remaining host femur, and stabilized with an interlocking nail. Progressive weight-bearing was allowed at 3 weeks with full weight-bearing achieved at 6 months.

The use of a telescoped structural allograft and intramedullary nailing as the second stage of the Masquelet induced membrane technique facilitated postoperative rehabilitation, increased surface contact between host and graft bone, and improved integration.
