With the aging of our society’s population, the number of patients with lumbar spinal stenosis in spine surgery is increasing. Neurological claudication due to lumbar spinal stenosis can seriously affect the physical function, quality of life and self-care ability of the elderly. For this group of elderly patients, in addition to some cases receiving surgical treatment, more patients choose non-surgical conservative treatment. However, there is not much clinical evidence on the exact outcome of conservative treatment for elderly patients with lumbar spinal stenosis with neurogenic claudication. To systematically evaluate the effectiveness of non-operative treatment in patients with lumbar spinal stenosis with neurological claudication, Carlo Ammendolia , DC, PhD, of the Toronto Institute for Health Policy, Canada, recently implemented a systematic evaluation study that included 56 studies involving 1851 patients through a screening of 8635 studies, including 21 trials. Each study was independently evaluated by two dedicated staff using 12 criteria. The clinical trials showed that calcitonin was not more effective than placebo or paracetamol, regardless of the applied dosage form and mode of administration. Prostaglandin, gabapentin or mecobalamin were not significantly more effective in improving walking distance. There is also evidence that epidural steroid hormone injections improve pain, function and quality of life in patients for up to 2 weeks compared to home exercise or inpatient physical therapy. A pilot study showed short-term lower extremity pain relief and functional improvement in patients who participated in exercise compared to those who did not intervene.6 Evidence from 6 studies suggests that multiple forms of non-surgical treatment measures are less effective compared to direct or indirect decompression (fusion or non-fusion) surgical treatment.
