摘要
OBJECTIVE:To investigate the application value of the Ilizarov technique for infection after the limb salvage operation of primary bone tumor.
METHODS:A retrospective analysis was made on the clinical data of 6 patients with infection treated with Ilizarov technique after limb salvage operation of primary bone tumor between July 2012 and April 2015. There were 4 males and 2 females, aged 18-40 years (mean, 28 years). Tumor types included 3 cases of osteosarcoma and 3 cases of giant cell tumor of bone. Tumor located at the left distal femur in 2 cases, at the right distal femur in 1 case, at the left proximal tibia in 1 case, and at the right proximal tibia in 2 cases. Six cases had recurring infection after debridement. The patients underwent operation 2 to 5 times (mean, 3.5 times). The time from tumor resection to visiting was 8-20 months (mean, 14.3 months). During operation, the internal implant was removed; infection and necrotic tissue was removed thoroughly; and the Ilizarov external fixator was installed. After operation, gentamycin normal saline was used for 2 to 3 weeks, and the sensitive antibiotic intravenous infusion was performed at the same time. After 1 week, the osteotomy lengthening was used.
RESULTS:All 6 patients were followed up for 6 to 18 months (mean, 12.2 months). Pin tract infection occurred in 1 case after operation; primary healing of incision was obtained in the other patients, and no related complications occurred. The external fixation time ranged from 6 to 16 months (mean, 11.5 months). The healing indexes ranged from 34 to 62 days/cm (mean, 52.0 days/cm). After removal of the external fixator, the knee range of motion ranged from 0 to 5° (mean, 3°) in extension, and from 120 to 130° (mean, 125°) in flexion. The American musculo-skeletal tumor society system (MSTS) function scoring was excellent in 3 patients, good in 2 patients, and fair in 1 patient, with an excellent and good rate of 83.3%. During follow-up period, there was no recurrence of infection; and no recurrence or metastasis was found in 3 patients with osteosarcoma.
CONCLUSIONS:Infection can be cured by Ilizarov technique after limb salvage operation of bone tumor.
