Summary
Surgical lamino-arthrectomy effectively treats lumbar spinal stenosis when conservative methods fail. This procedure enlarges the spinal canal, with good outcomes reported in 86.2% of patients.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Context:
- Lumbar spinal stenosis often requires surgical intervention when conservative treatments prove insufficient.
- Severe pain and neurological deficits are key indicators for surgical consideration.
- Surgical goals include canal enlargement for dural decompression (central stenosis) and root decompression (lateral stenosis).
Purpose:
- To describe lamino-arthrectomy techniques for lumbar spinal stenosis.
- To present the results and complications of lamino-arthrectomy in 202 operated cases.
- To evaluate the surgical efficiency of extensive lamino-arthrectomy in symptomatic narrow lumbar canals.
Summary:
- Two surgical techniques, lamino-arthrectomy and recalibration, are discussed.
- Lamino-arthrectomy involves posterior resection with partial arthrectomy and vertebral body exploration.
- The 'lobster shell' technique is a multi-level laminectomy variation.
- Complications included dural/radicular injuries during surgery, post-operative hematomas, infections, root involvement, paraplegia, destabilizations, and recurrences.
- Good results were achieved in 86.2% of patients, with 71.4% regaining normal locomotion.
Impact:
- Results demonstrate the surgical efficacy of extensive lamino-arthrectomy for symptomatic narrow lumbar canals.
- The procedure shows effectiveness in improving symptoms and restoring locomotion.
- Posterolateral arthrodesis with osteosynthesis is discussed as a complementary technique.
