[L1-2 lumbar disc herniation: a case report].
A 49-year-old female presented a two-year history of pain in the right thigh and lower back. Neurological examination on admission demonstrated weakness of the right iliopsoas and quadriceps, hypesthesia on the right L1-2 dermatome. Radiological examination including myelography, CT myelography and discography disclosed an L1-2 herniated disc. Sagittal MRI also revealed an L1-2, an L4-5 and L5-S1 protruded disc. A posterior microdiscectomy (Love's method) was performed for the L1-2 disc. A controlateral protruded disc which compressed the L-2 nerve root was identified and partially removed. The postoperative myelography showed residual disc. The patient was free from pain and regained normal sensorimotor function. Love's posterior microdiscectomy has a disadvantage in that the operative field is limited. Careful surgical procedure was needed to avoid injury to nerve roots and the cauda equina in a tight L1-2 lumbar canal.
