Introduction Several reconstructive procedures have been used in management of large tibial bone defects including bone
graft, bone transport (distraction osteogenesis) using various external fixators, and vascularized bone graft. Each of these
procedures has its limitations and complications. The study describes gradual medial fibular transfer using Ilizarov external
fixators in management of patients with large tibial defect, either following infection or trauma.
Patients and methods Between May 2011 and June 2013, 14 patients were prospectively included in the current study. The
inclusion criteria were large tibial defect due to trauma or infection with severe soft tissue compromise, and small or poor
tibial bone remnants making bone lengthening difficult. Exclusion criteria were patients with vascular or nerve injuries. The
average age of the patients was 31.64 (±6.5) years. Medial fibular transfer was done for all patients using Ilizarov at a rate
of 0.5 mm twice daily. Iliac bone graft was used in all patients after the transfer.
Results The average segmental bone defect of the tibia was (13.2±2.6), ranging between 8 and 18.6 cm. Union was achieved
in all patients with average fixator time was 32.42 (±4.32) weeks. Average follow-up after removal of the fixator was 40.5
(±6.9) months.
Conclusion Gradual fibular transfer by Ilizarov external fixator is a reliable technique in management of post-traumatic and
post-infection large tibial bone defects with good clinical outcome, and with few complications. |
