OBJECTIVETo observe the therapeutic effects of iliac nail in the treatment of lumbar sacral and pelvis reconstruction.

METHODSForm January 2004 to February 2010,10 patients (4 males and 6 females, ranging age from 25 to 75 years, with an average of 46.5 years ) were treated. Among the patients, 5 cases were L5S1 vertebral tuberculosis, 2 cases were sacral giant-cell tumors and 3 cases were severe osteoporosis combined with lumbar sacral slipping. The main symptoms manifested low back pain, limited activity and dysphasia before treatment. Iliac nail and lumbar-sacral pedicle screw were used for reconstruction of lumbar-sacral spine and pelvis. Nakai scale was used to evaluate therapeutic effects, Suk scale for osseous fusion.

RESULTSAll operations were succeful, obtained primary healing. All the patients were followed up, and the mean time of follow-up was 24 months (ranged from 18 to 36 months). The complications, such as weakness and decreased sensation of lower libs and activity, increased spinal cord injury, were not occurred after operation. According to Nakai scale, 7 cases got excellent result, 2 good and 1 fair. All bone graft were bony fusion with an average time of 3.5 months.

CONCLUSIONIliac nail can fixed well between lumbar vertebra and pelvis and solve the problem of fixation due to pathological changes of lumbosacral region. It is an ideal method of less blood loss and operating time.
