Abstract:
[Objective]To investigate the operation indications and techniques of the ISOLA spinal system in reconstruction of the lumber-pelvis continuity after resection of high-level sacral tumors. [Method]A retrospective study was performed in 43 patients with high-level sacral tumor (HLST) between July 2001 to January 2007. Symptoms, signs, histological findings of the tumors and their outcomes were analyzed. All patients underwent resection of HLST and spinopelvic reconstruction with ISOLA spinal system,11 unilateral and 32 bilateral.[Result]Among the 43 patients, 33(77.1%)had chordoma, giant cell tumor of bone and neurogenic tumors. Thirty-four patients alive were followed-up for an average of 35 months(12~62 months), 5 patients had a recurrence of chordoma and 29 patients with HLST were under control. The pain originated from the lumbosacral joint and the spinal nerve root was obviously relieved.The patients could stand and ambulate normally. No loose screw or broken rod were found.X-rays showed no signs of the enlarged screw canal or lowered lumbar spine.The effect was 76.5%(26/34) excellent judged by the ISOLS system.[Conclusion]Spinopelvic reconstruction by ISOLA system after resection of HLST is characterized by easy manipulation, less complications and instant stable fixation. It may be widely used in the clinical practice.
