Case: The patient sustained a pathologic fracture through chronic osteomyelitis of the tibia. Treatment involved resection of bone and soft tissue, leaving a 15-cm diaphyseal tibial defect. We designed a construct to allow for trifocal bone transport using a magnetic intramedullary lengthening nail connected to cables. This technique uses cables secured to the proximal tibia, the nail, and the transport segments. Conclusion: This case details the successful use of trifocal cable-assisted bone transport through a magnetic lengthening intramedullary nail. This technique can successfully be used to reconstruct diaphyseal bone defects that are longer than the stroke length of the magnetic nail.
