Abstract:

BACKGROUND: Lumbar spinal stenosis can severely affect the activities and functions of the lower limbs, and even cause paralysis.
OBJECTIVE: To evaluate the clinical effect of intervertebral bone graft with internal fixation for the treatment of lumbar spinal stenosis.
METHODS: The lumbar spinal stenosis patients treated with posterior decompression and intervertebral bone graft with internal fixation were followed-up. The effect of intervertebral bone graft with internal fixation for the treatment of lumbar spinal stenosis was evaluated through assessing the clinical symptoms and improvement of signs, recovery of neurological function, as well as intervertebral bone graft and fusion and the occurrence of complications. The effects of posterior decompression and intervertebral bone graft with internal fixation and simple decompression for the treatment of lumbar spinal stenosis were compared, in order to further determine the treatment of intervertebral bone graft with internal fixation.
RESUTLS AND CONCLUSION: The follow-up results of the lumbar spinal stenosis patients treated with posterior decompression and intervertebral bone graft with internal fixation showed that the symptoms of low back pain, partial limb sensory disturbances and intermittent claudication were improved significantly; the neurological recovery score could be up to 90% or above. Radiographic examination showed good intervertebral bone graft and fusion with less complication of nerves, blood vessels and dural injury. Comparative study showed that the excellent and good rate of posterior decompression and intervertebral bone graft with internal fixation can reach to 95.2%, while the excellent and good rate of simple decompression was 23.8%, indicating that the effect of posterior decompression and intervertebral bone graft with internal fixation was significantly better than that of simple decompression.
