%X OBJECTIVE: To examine the relationship between sagittal balance parameters and different symptoms of spinal disease in patients with lumbar canal stenosis (LCS) and controls. METHODS: In this prospective, diagnostic, case-control study, we included all patients consecutively admitted to a public teaching hospital for surgical treatment of LCS between July 2010 and October 2011, aged more than 40 years, with back pain plus radiculopathy or neurogenic claudication, and controls without LCS. Magnetic resonance and x-rays allowed the measurement of sagittal axis parameters. Clinical data, the Oswestry Disability Index and the visual analogue scale of pain were assessed. RESULTS: 23 patients were in the Stenosis group, and 17 were controls. The Stenosis group presented lower values of total lumbopelvic lordosis and regional lordosis L1, L2 and L3. In LCS patients and back pain, total lumbopelvic and regional lordosis at L1, L2 and L3 were smaller. Those with stenosis and radiculopathy had higher values of pelvic tilt and lower total lumbopelvic lordosis and regional lordosis in L1 and L2. In patients with claudication, regional lumbopelvic lordosis in L1 and L2 and the T9 sagittal offset were smaller. All patients with pain had higher values of thoracic kyphosis, regional lumbopelvic lordosis in L1, lower values for pelvic tilt, sagittal T1 offset, sacro-femoral distance and overhang compared to patients without pain. CONCLUSIONS: This study shows significant correlations between symptoms and sagittal axis parameters between patients with and without spinal canal stenosis and also in subgroups of the patients with stenosis with different complaints. OBJETIVO: Analizar la relaci¨®n entre los par¨¢metros del equilibrio sagital y los diversos s¨ªntomas de enfermedad espinal en pacientes con estenosis del canal lumbar (ECL) y sus controles. M¨¦TODOS: En esta perspectiva, de estudio de diagn¨®stico, de control de casos, incluimos a todos los pacientes admitidos, consecutivamente, a un hospital universitario p¨²blico para tratamiento quir¨²rgico de ECL, desde julio de 2010 hasta octubre de 2011, con m¨¢s de 40 a os de edad, con dolor de espaldas m¨¢s radiculopat¨ªa o claudicaci¨®n neurog¨¦nica, y controles sin ECL. La resonancia magn¨¦tica y los rayos X permitieron hacer la medici¨®n de los par¨¢metros del eje sagital. Los datos cl¨ªnicos, el ¨ªndice de Incapacidad de Oswestry y la escala an¨¢loga, visual de dolor fueron evaluados. RESULTADOS: 23 pacientes estuvieron en el grupo de Estenosis y 17 fueron los controles. El grupo de Estenosis present¨® valores m¨¢s bajos de lordosis lumb
