ObjectiveThis study was to compare the effectiveness of Masquelet technique versus Ilizarov bone transport in the treatment of lower extremity bone defects following posttraumatic osteomyelitis.Patients And MethodsWe retrospectively reviewed 39 patients who had been treated at our department for lower extremity bone defects following posttraumatic osteomyelitis. They were 30 males and 9 females with a mean age of 39.18 (range, 12-63 years). The infected bone defects involved 26 tibias and 13 femurs. The mean length of the bone defects after radical debridement was 6.76cm (range, 2.7-15.7cm). Masquelet technique (MT, group A) was used in 20 patients and Ilizarov bone transport (IBT, group B) in 19 ones. The measurements were bone outcomes (union, deformity, infection and leg-length discrepancy) and functional outcomes (significant limping, joint contracture, soft tissue dystrophy, pain and inactivity).ResultsThe mean follow-up after removal of the apparatus was 25.26 months (range, 14-51 months). The mean finite fixator time was 10.15 months (range, 8-14 months) in group A versus 17.21 months (range, 11-24 months) in group B. The bone outcomes were similar between groups A and B [excellent (5 vs. 7), good (10 vs.9), fair (4 vs. 2) and poor (1 vs. 1)]; group A showed better functional outcomes than group B [excellent (8 vs. 3), good (9 vs. 6), fair (3 vs. 8) and poor (0 vs. 2)].ConclusionsIn the treatment of segmental lower extremity bone defects following posttraumatic osteomyelitis, both IBT and MT can lead to satisfactory bone results while MT had better functional results, especially in femoral cases. IBT should be preferred in cases of limb deformity and MT may be a better choice in cases of periarticular bone defects.Copyright © 2017 Elsevier Ltd. All rights reserved.
