Ilizarov technique in the treatment of long segmental bone defect of tibia

Objective To investigate the clinical efficacy of the Ilizarov external fixation bone transportation in the treatment of tibial segmental bone defects.Methods 21 cases with long segmental bone defect of tibia were treated by using Ilizarov bone transportation.Results The operative time was 70 ～ 95(75 ± 4.2) min.All patients were followed up for 14 ～ 30(17.6 ± 6.5) months.Bone transportation length was 6 ～ 10(7 ± 4.2) cm.Callus mineralization time was 11 ～ 20(12.1 ± 3.5) weeks,external fixation time was 12 ～ 20(14.9 ± 3.3) months,2 cases of clubfoot deformity which were given Achilles tendon extend;1 case nonunion which were given iliac bone graft;2 cases of pin tract infection which were given debridement.The results were evaluated by the Johner-Wruh standard: excellent in 10 cases,good in 7,and poor in 4.Conclusions Ilizarov external fixation bone transportation is effective in the treatment of tibial segmental bone defects.
