Preserving the Knee in the Setting of High Segmental Tibial Bone and Massive Soft-Tissue Loss Using Vascularized Distal Tibial Bone Docking and a Foot Fillet Flap: A Case Report.

Case: We discuss our reconstructive approach to avoid an above-knee amputation in a 33-year-old man presenting after lower extremity crush injury. We used a vascularized tibial bone flap and a foot fillet flap to restore length and joint functionality to the residual limb. The patient ambulates with good prosthetic fit on durable heel pad skin and 100° active knee motion.

Conclusion: This pairing of intramedullary nail with vascularized bone flap and fillet flap to address soft-tissue coverage and retain limb length is a useful tool in traumatic lower extremity injury management, providing an alternative technique for tibial bone graft stabilization with robust, sensate tissue coverage.
