  • Abstract
  • Look Inside

A 49-year-old female presented a two-year history of pain in the right thigh and lower back. Neurological ex-amination 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 dis-closed an L1-2 herniated disc. Sagittal MRI also re-vealed an L1-2, an L4-5 and L5-S1 protruded disc. A posterior microcliscectomy (Love's method) was per-formed for the L1-2 disc. A controlateral protruded disc which compressed the L-2 nerve root was identi-fied and partially removed. The postoperative myelography showed residual disc. The patient was free from pain and regained normal sensorimotor func-tion. Love's posterior microcliscectomy has a disadvan-tage in that the operative field is limited. Careful sur-gical procedure was needed to avoid injury to nerve roots and the cauda equina in a tight L1-2 lumbar canal.
