OLIVERA LABORDA, Horacio Federico; VIACAVA SIAZARO, Felipe Alejandro; NORIA, Alejandro  and  REY NANDE, Rogelio. Treatment of Massive Defects Tibia. Bone Transport Technique with Fixator AO. Anfamed [online]. 2018, vol.5, n.2, pp.130-140. ISSN 2301-1254.


Bone transport is the slow transportation of the bone fragment along a bone defect, providing distraction osteogenesis.


To describe the surgical technique of bone transport using the AO external fixator and to present the result of this procedure in tibial diafisis defects of more than 4 cm long, which were the result of severe open fractures or infected no unions.

Material and Methods:

This is a retrospective, descriptive study of 14 patients treated in several centers in Montevideo from April 2011 to April 2015.


The average age of the patients was 32 years (15-32), the average bone loss 6,7 cm (4-11), the distraction speed 0,58 mm/day, the mean distraction period 92 days (35-172) and the mean time external fixation was 194 days. The mean follow up was 13 months (6-27). All patients needed an additional surgical procedure in the docking site. Bone healing was accomplished in 9 patients and there were 2 no unions. There were 2 further patients who abandoned the treatment and another patient who requested amputation. At the latest follow up there was no recurrence of infection.


Bone transport using AO external fixator, is a valid alternative for the treatment of segmental bone loss of the diafisis of the tibia with or without infection.
