Summary
Neurogenic intermittent claudication (NIC) is strongly linked to two-level spinal canal stenosis. Degenerative changes like facet joint disease, spondylolisthesis, and scoliosis are predisposing factors for NIC.
Area of Science:
- Orthopedics
- Neurosurgery
- Radiology
Background:
- The exact cause of neurogenic intermittent claudication (NIC) remains unclear.
- This study investigates the
- two-level
- spinal stenosis theory as a pathological basis for NIC.
Purpose of the Study:
- To determine the association between two-level spinal stenosis and NIC.
- To identify predisposing factors for NIC.
Main Methods:
- A case-control study involving 45 NIC patients and 45 controls with chronic low back pain.
- Diagnostic methods included patient history, physical examination, X-rays, CT, and MRI.
Main Results:
- Two-level spinal canal stenosis was significantly more prevalent in the NIC group (88.9%) than controls (37.8%).
- The NIC group showed higher rates of facet joint degeneration (77.8%), spondylolisthesis (42.2%), and scoliosis (35%) compared to controls.
- No significant difference in lumbosacral angle was observed between groups.
Conclusions:
- Two-level spinal canal stenosis is a strong pathological factor in NIC.
- Degenerative joint disease, spondylolisthesis, and scoliosis are identified as predisposing factors for NIC.
