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.
采用改良诱导膜技术治疗外伤性 10cm 感染性股骨干节段性骨缺损。第一阶段包括清创和置入抗生素骨水泥间隔器和 2 枚 Ender 钉。采用 14cm 结构性骨同种异体骨进行重建，将其倒置并套入剩余宿主股骨的两端，并用交锁钉固定。术后 3 周开始逐渐负重，6 个月时可完全负重。
采用套叠结构性同种异体骨和髓内钉作为 Masquelet 诱导膜技术的第二阶段，有利于术后康复，增加了宿主骨与移植物骨之间的表面接触，提高了整合效果。
