[Clinical and therapeutical aspects of lumbar stenosis in the gabriel touré hospital: about 24 cases].

INTRODUCTION

Lumbar stenosis is a disease caused by a conflict between the neural structures (spinal cord and nerve roots) and spinal structures (bones and ligaments). The objectives of this study were to highlight the frequency, the diagnosis and therapeutics options, and to evaluate the treatment outcomes.

PATIENTS AND

METHODS

It was a retrospective study from January 2012 to December 2012 including 24 patients admitted to the neurosurgical department of the Gabriel Touré Hospital.

RESULTS

The frequency of lumbar stenosis was 6.19% of all neurosurgical diseases. The sex-ratio was 0.71. The 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%. Degenerative lumbar stenosis was the most common form, found in 66.67% of cases. Surgical treatment was performed in 29.17% of cases. The outcome was good in 85.6% of cases.

CONCLUSIONS

Lumbar stenosis is a prevalent disease that occurs typically occurs around 50 years of age. The diagnosis was confirmed by myelography and a post myelographic CT scan. Good outcomes are achieved with both surgical or medical treatments.
