  • SIMULTANEOUS REPAIR OF TIBIA BONE DEFECT AND REFRACTORY SOFT TISSUE DEFECT BY BONE TRANSPORT TECHNIQUE

    ObjectiveTo explore the feasibility and effectiveness of bone transport technique for simultaneous repair of tibia defect and refractory soft tissue defect. MethodsThirty-five patients with tibia bone defect combined with refractory soft tissue defect were treated between January 2010 and December 2014, and the clinical data were retrospectively analyzed. There were 21 males and 14 females with an average age of 29 years (range, 18-47 years). All patients had Gustilo type Ⅲ open tibial fractures, which were caused by traffic accident. Fracture located at the upper 1/3 of the tibia in 1 case, at the middle 1/3 of the tibia in 19 cases, and at the lower 1/3 of the tibia in 15 cases. All patients underwent external fixation after 4-10 hours of trauma, and tibial skin necrosis, infection, and purulent exudation were observed after 5-10 days of operation. The time from injury to admission was 21 days to 5 months (mean, 2 months). After debridement, the average length of tibia defect was 8 cm (range, 6-11 cm); the area of soft tissue defect was 6 cm×5 cm to 10 cm×8 cm. Orthofix external fixation was applied to tract the bone and soft. ResultsAll 35 patients were followed up 12-22 months (mean, 16 months). The average time of bony healing was 15 months (range, 9-20 months), and no obvious force line offset was found. Osteotomy segment was extended from 6 to 11 cm (mean, 8 cm); after treatment, the external fixation support was retained for 2 to 10 months (mean, 5 months). No blood vessel and nerve injuries were found during treatment, and no osteomyelitis and refracture happened after operation. The skin and soft tissue defects healed, and the healing time was 1 to 3 months (mean, 1.3 months). Different degrees of infection occurred in 5 cases, and was cured after dressing change. According to Johner-Wruhs' evaluation criteria after external fixator was removed, the results were excellent in 26 cases, good in 5 cases, and moderate in 4 cases, with an excellent and good rate of 88.6%. ConclusionBone transport technique can simultaneously repair tibia bone defect and soft tissue defect by continuous bone and soft tissue traction.
