Induced Membrane Technique (Masquelet)

This technique is usually performed in two stages: the first stage involves placing a drug-containing bone cement spacer on the basis of debridement and stabilization to induce the formation of a bioactive membrane, with internal/external fixation if necessary. After the infection is controlled and the induced membrane is formed, the second stage involves opening the membrane sac, removing the spacer, and implanting a graft mainly composed of autologous cancellous bone, which can be supplemented with allogeneic or alternative materials, and maintaining stability to promote bone healing. Postoperative monitoring includes wound and inflammation indicators, and follow-up examinations are performed as planned. The above is general health information, not medical advice; the specific plan should be based on specialist evaluation and hospital protocol.
