Summary
A novel micro-endoscopic open-door laminoplasty (ODL) offers a reliable solution for multilevel cervical spondylotic myelopathy. This minimally invasive technique achieved excellent decompression and symptom improvement with minimal muscle atrophy.
Area of Science:
- Neurosurgery
- Spinal Surgery
Background:
- Open-door laminoplasty (ODL) is a standard treatment for cervical spondylotic myelopathy.
- Minimally invasive endoscopic techniques are emerging but face challenges with decompression uniformity.
- ODL under endoscopic guidance is technically demanding with limited case reports.
Observation:
- A 73-year-old male with C5-7 cervical spinal stenosis presented with upper limb numbness and gait disturbance.
- Novel instruments and techniques were developed for micro-endoscopic ODL in narrow spinal canals, performed by a single surgeon.
- The procedure achieved sufficient spinal canal expansion without residual stenosis.
Findings:
- The micro-endoscopic ODL resulted in significant improvement of myelopathy symptoms.
- Minimal muscle atrophy and successful bone fusion were observed postoperatively.
- This technique proved more effortless and reliable than traditional endoscopic ODL with suture anchors.
Implications:
- This minimally invasive approach offers a viable and stable option for treating cervical spondylotic myelopathy.
- Further research and experience may refine this technique for broader application.
- It represents a promising advancement in endoscopic spine surgery.
