Aspect clinique et thérapeutique du canal lombaire : à propos de 24 cas enregistrés au CHU Gabriel Touré de Bamako

Introduction : Lumbar stenosis is a disease caused by a conflict between the neural structures (spinal cord and nerve roots) and spine structures (bones and ligaments).The objectives of this work were to highlight the frequency, the diagnosis and therapeutics options and to evaluate the outcome. Patients and methods : It was a retrospective study from January 2012 to December 2012 including 24 patients admitted to the neurosurgical department of Gabriel Toure Hospital. Results: The frequency of lumbar stenosis was 6.19% of all neurosurgical diseases. The sex-ratio was 0.71. The mean age ranged from 28 to 81 years with an average of 52 years. The neurogenic claudication was found in 87.5%. The straight leg raising test was positive in 41.7% of cases. The most vertebras involved were L4 and L5. Lumbar disc herniation was associated in 70.83%. The degenerative lumbar stenosis was the most common form in 66.67%. Surgical treatment was performed in 29.17%. The outcome was good in 85.6%. Conclusions : Lumbar stenosis is a prevalent disease that occurs most often in the fifth decade. The diagnosis is made by myelography with postmyelograpy CT scan. Good outcomes are achieved with treatment either surgical or medical.
