Treatment Methods for Tibial Fracture Defects
- see tibial non unions
- OTA classification:
- type I is there is loss of 50% of circumference of bone and less than 2 cm defect;
- consider exchange nailing
- ref: Critical-sized defect in the tibia: is it critical? Results from the SPRINT trial.
- type2 if there is loss of more than 50% of circumference of bone (and/or fractures with gaps of 2-6 cm)
- bone grafts or bone graft substitutes in addition to reamed exchange nailing
- type 3 if there is a missing bone segment (more than 6 cm defect)
- requires bone transport techniques;
- consider bone grafting at 6 weeks post injury;
- The timing of flap coverage, bone-grafting, and intramedullary nailing in patients who have a fracture of the tibial shaft with extensive soft-tissue injury.
- Early prophylactic bone grafting of high-energy tibial fractures.
- Study finds 47% primary union rate in tibia patients with ‘critical-sized’ bone defects
- Current Practice in the Management of Segmental Bone Defects Among Orthopaedic Trauma Surgeons.
- Treatment Options:
- tibial bone grafting (bone graft harvest technique)
- papineau technique:
- Intramedullary infections treated with antibiotic cement rods: preliminary results in nine cases.
- posterolateral bone grafting:
- tibial-fibular synostosis using cancellous bone may be indicated in some cases;
- ref: Posterolateral bone graft of the tibia.
- osteogenic proteins
- cancellous bone grafting: / bone graft harvest technique:
- some recommend adding powered antibiotic to the cancellous graft;
- w/ defects less than 6 cm iliac crest bone grafting may be sufficient;
- ref: Autologous marrow injection as a substitute for operative grafting of tibial nonunions.
- synthese reamer aspirator
- induced membrane:
- free fibular transfer;
- w/ defects greater than 6 cm, free fibular transfer from contralateral leg is indicated;
- see free fibular harvest;

- distraction histiogenesis
- limb lengthening fixators

- fibular transport:
- in the report by Atkins RM, et al (1999), the authors discuss a method of tibialisation of the fibula (for massive tibial bone loss) using the Ilizarov fixator system;
- all had successful transport, proximal and distal union, and hypertrophy of the graft without fracture;
- one developed a squamous-cell carcinoma which ultimately required amputation of the limb;
- advantage of IVFT is that the fibular segment retains its vascularity without the need for microvascular dissection or anastomoses;
