Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Masquelet's induced membrane technique is a two-stage reconstructive surgery for severe bone fractures commonly used by military orthopedists. The particularity of this technique relies on the synthesis of a biological membrane induced by the transient implantation of a surgical cement (= 1st stage surgery). The presence of the induced membrane in the reconstruction space defines a microenvironment or "biological chamber" favourable to osteogenesis, positively influencing the repair of the lesion after implantation of an autologous bone graft (= 2nd stage of surgery).

In view of the excellent clinical results obtained with this procedure, the Masquelet technique has gradually become a reference treatment in the field of orthopedic and trauma surgery.

However, orthopedic surgeons sometimes observe failures in bone consolidation. To our knowledge, the role played by induced membrane in these therapeutic failures has never been studied.
