The efficacy of flexion brace in the treatment of lumbar cannal stenosis was evaluated on 42 patients (questionnaire, 42; consultation, 26). Improvement of symptoms was obtained in 78.6% of them. Intermittent claudication was favorably relieved after the bracing and an average walking distance had increased from 220m to 1013m. Radiographic assessment of 25 patients who had worn the flexion brace revealed that most of them showed slight blocking of lumbar extension and mild decrease in lumbar lordosis. The results in patients with spodylosis deformans were significantly good compared with degenerative spodylolisthesis or spondylolytic spondylolisthesis.
