Regeneration of a missing segment of bone by slowly moving a bone segment across the gap.
What is it?
Bone transport is a technique used when a segment of bone is missing — due to infection, trauma or tumour removal. A cut is made in the healthy bone near the defect, and the resulting bone segment is slowly moved across the gap using the Ilizarov frame. As the segment moves, new bone forms behind it, gradually filling the defect.
Who needs it?
- Large bone defects after infection (osteomyelitis)
- Bone loss after severe fracture
- Defects after removal of infected or dead bone
- Failed bone grafting procedures
- Non-union with bone loss
How is it treated?
Surgery involves applying the Ilizarov frame and making a bone cut in the healthy bone. After a rest period, the transport segment is moved at approximately 1 mm per day. The process continues until the segment reaches the other end of the defect. A second procedure may be needed to stimulate fusion at the meeting point.
What to expect
Treatment duration depends on the size of the defect — larger defects require longer transport periods. The frame is worn throughout the transport and consolidation phases. Physiotherapy is important to maintain joint function. Regular X-rays monitor the progress of bone formation and transport.
Risks and Limitations
Like any surgery, this treatment carries risks. These can include pin-site infection, joint stiffness, delayed bone healing, and the need for further procedures. Results depend on age, general health, the condition being treated and following the treatment plan. Dr. Hoda will explain the risks that apply to you before you decide.
