Abstract: | Abstract The aim of this study was to evaluate the short- to medium-term results (up to 2 years) of conservative and surgical treatments of patients with symptomatic lumbar stenosis. To our knowledge, no previous study has provided strict indications for conservative or surgical treatment. We retrospectively studied 184 patients, who were divided into 3 groups according to JOA (Japanese Orthopaedic Association) score. A cutoff JOA score was arbitrarily fixed at 7. Patients with a score ≤7 (n=12; group A) underwent surgery, while patients with a score >7 (n=172) were conservatively treated. Group A included patients surgically treated within two months from diagnosis. Group B consisted of 144 patients who received conservative treatment, while group C (28 patients) represented patients who underwent surgery after a period of failed conservative treatment. The outcomes of surgical and conservative treatments were evaluated after 12 and 24 months, and were rated as satisfactory, not totally satisfactory, not satisfactory or totally unsatisfactory. Conservative treatment consisted of physical, orthotic and drug therapy, whereas surgical treatment included spinal decompression and instrumentation (if indicated), either rigidly or dynamically performed. Surgery was indicated in 22% of all patients and we obtained excellent results in 85% of them. Operative treatment provides excellent results for patients with severe clinical presentation (JOA score ≤7), while individuals with mild to moderate spinal stenosis (JOA score >7) should receive conservative treatment. |
