Summary
A 49-year-old woman with L1-L2 herniated disc experienced pain relief and regained function after posterior microdiscectomy. The procedure, while effective for lumbar disc herniation, requires careful technique due to a limited operative field.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- A 49-year-old female presented with a two-year history of right thigh and lower back pain.
- Neurological deficits included weakness in the right iliopsoas and quadriceps, and hypesthesia in the right L1-L2 dermatome.
Observation:
- Radiological imaging revealed an L1-L2 herniated disc, along with L1-L2, L4-L5, and L5-S1 protruded discs.
- A posterior microdiscectomy (Love's method) was performed for the L1-L2 disc, with partial removal of a contralateral protruded disc compressing the L-2 nerve root.
Findings:
- Postoperative myelography indicated residual disc material.
- The patient achieved complete pain resolution and restoration of normal sensorimotor function.
Implications:
- Love's posterior microdiscectomy is effective for treating lumbar disc herniation.
- The technique necessitates meticulous surgical execution to prevent nerve root or cauda equina injury, especially in narrow lumbar canals.
