Purpose: Posttraumatic bone defects in patients with severe, open injuries of the lower extremity are a significant challenge for orthopaedic trauma surgeons. The induced-membrane technique, which also is known as the Masquelet technique, generally is successful in achieving bony union. This video demonstrates the Masquelet technique for the management of a large (18 cm) femoral defect.

Methods: The Masquelet technique is a two-stage process. The first stage involves débridement of all devitalized tissue, open reduction and internal fixation, and the placement of a cement spacer with or without antibiotic agents. In the second stage, which is carried out at least 6 weeks after the first stage, the spacer is removed, and the resulting void is filled with bone graft.

Results: This video reviews the relevant patient injury presentation, initial management, and indications for the Masquelet technique. The second stage of the Masquelet technique is featured in the video.

Conclusions: In general, the Masquelet technique is a reliable method for the management of large segmental bone defects. In addition, this relatively simple technique is suitable for patients with or without an infection.
