Abstract:
Objective To compare the effects of bone transport versus induced membrane technique for large segmental tibial defects.Methods The clinical data were analyzed retrospectively of 89 patients with large segmental tibial defect who had been treated at Department of Orthopaedics,Wuxi No.9 People's Hospital from June 2005 to February 2017 using bone transport or induced membrane technique.They were 58males and 31 females,aged from 13 to 74 years (average,38.0 years).The bone transport group had 59cases and the induced membrane technique group 30 cases.The 2 groups were compared in terms of preoperative general data and postoperative bone nonunion,bone healing time,complications and functional recovery of the adjacent joint.Results There were no statistically significant differences between the 2groups in terms of age,gender,cause or type of defects,associated injury,course of disease,functionary scores of the adjacent joint or number of operations,showing compatibility between the 2 groups (P ＞ 0.05).All the patients were followed up for 12 to 48 months (average,20 months).The bone transport group had significandy longer clinical healing time (14.7 ± 5.4 months) and significantly higher incidences of major complications (50.8％),minor complications (57.6％) and overall complications (83.1％) than the induced membrane technique group (11.2 ± 2.8 months,16.7％,26.7％ and 30.0％,respectively) (P ＜ O.05),but significantly lower functionary scores of the adjacent joint (86.4 ± 5.0 points) than the induced membrane technique group (88.8 ± 4.9 points) (P ＜ 0.05).Conclusions Both bone transport and induced membrane technique are effective repairs for large segmental tibial defects.However,induced membrane technique may be superior to bone transport in terms of bone healing,complications and functional recovery.
