[Lateral lumbar disk hernia].
Eleven cases are reported of lateral lumbar herniated disc, an anatomical form presenting fairly atypical features and of relatively recent discovery. The patients presented with a highly painful single root lesion usually affecting L4 and L5 roots. Saccoradiculography was negative in almost all cases whereas computed tomography imaging allowed easy diagnosis of a lateral herniated disc, and demonstrated its foraminal or extraforaminal site. An appropriate surgical approach was thus possible, extremely lateral forms requiring an extraisthmian approach.
