L'anatomie des obstacles radiculaires lombaires: analyse anatomo-radiologique des checs de la chirurgie de libration

Improvement in pre and post-operative imaging has modified the diagnosis of lumbar radicular compression. CT scanning and MRI led to the advent of bodysection anatomy which allows an optimal analysis of the relation between container and content, in regard to the lumbar radicular canal. However, myelography remains an important method of analysis of dynamic obstructions. The authors report the retrospective analysis of 102 cases of failures in surgery for lumbar radicular release frequently difficulties in diagnosis are due to a lack of precision in anatomic and radiological interpretation of the clinical situation. This analysis is based on the classical radicular segmentation with 4 zones.
