To clarify the “natural” course of spinal stenosis, the following retrospective study of non-operative patients was done in our clinic. The average patient’s age was 65.2 years old, with an average follow-up term was 100 months. 16 patients already died, 13 patients were being treated for other diseases. 22 patents reported improvement, 23 patients have had ongoing symptoms of spinal stenosis and, 8 of this latter group have had self-described conservative treatments, while 19 patients got worse and had surgery at another hospital. We had evaluated instances of intermittent claudication using treadmill test. Patients able to walk more than 500m on the treadmill obtained a better prognosis. We concluded that patients with radicular symptoms had better prognosis than patients with cauda equina symptoms.
