АНАЛИЗ ПРИЧИН РЕВИЗИОННЫХ ОПЕРАЦИЙ ПРИ ХИРУРГИЧЕСКОМ ЛЕЧЕНИИ БОЛЬНЫХ С ПОЯСНИЧНЫМИ СТЕНОЗАМИ ДЕГЕНЕРАТИВНОЙ ЭТИОЛОГИИ

Abstract

Objective. To analyze the reasons for revision surgery after decompression and stabilization in patients with degenerative lumbar spinal stenosis. Material and Methods. A total of 308 patients with degenerative lumbar spinal stenosis were operated on. They underwent decompression and stabilization surgery using transpedicular fixation involving from 1 to 8 spinal motion segments. Results. Clinical manifestations of radiculopathy and back pain were completely eliminated in 166 (53.9 %) patients. Another 86 (27.9 %) patients reported the absence of radicular pain syndrome with sustained mild low back pain during physical exertion. Significant reduction in radicular and low back pain was achieved in 49 (15.9 %) patients. Poor long-term results of surgical treatment requiring revision surgery in the long-term period were detected in 30 (16.1 %) patients. Conclusion. Multi-level surgery for lumbar spinal stenosis increases the risk and probability of indications for revision in the long-term period. When performing extended decompression and stabilization procedure at four or more spinal motion segments including the L5-S1segment stabilization, it is advisable to insert caudal pedicle screws into posterior portions of the os illium instead of the S1 vertebral body.
