Summary
This study on cervical myelopathy patients found that bilateral open laminoplasty with artificial laminas achieved a 65% recovery rate. The technique demonstrated good adaptation and maintained spinal canal enlargement, with reduced motion restriction.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Cervical myelopathy requires surgical intervention to decompress the spinal cord.
- Laminoplasty is a common surgical technique for treating cervical myelopathy.
- Artificial laminas offer a potential alternative to traditional grafting materials.
Observation:
- Sixty-five patients with cervical myelopathy underwent bilateral open laminoplasty using artificial laminas.
- Patients were followed for over two years post-surgery.
- Radiographic evaluations (CT, dynamic) assessed lamina adaptation and canal dimensions.
Findings:
- A mean recovery rate of 65% was observed using the Japanese Orthopaedic Association scoring system.
- Patients without complications showed a higher recovery rate of 72%.
- Artificial laminas demonstrated good adaptation, maintaining spinal canal enlargement without reduction.
Implications:
- The procedure is technically straightforward with minimal blood loss.
- It effectively prevents fat graft migration and facilitates bone grafting.
- Optimized fixation and exercises mitigate postoperative range of motion limitations, improving patient outcomes.
