Summary
Eccentric spinal canal compression from herniated discs or stenosis predominantly caused contralateral limb symptoms in five patients. Surgical decompression led to immediate symptom relief, highlighting the importance of addressing even eccentric spinal pathologies.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Neurology
Background:
- Spinal stenosis and herniated discs can cause significant neurological deficits.
- Eccentric compression of the dural sac is less commonly described but can lead to focal neurological deficits.
Purpose of the Study:
- To describe the clinical presentation and surgical outcomes of patients with eccentric spinal canal compression.
- To highlight the contralateral neurological findings associated with eccentric spinal compression.
Main Methods:
- Retrospective case series of five patients.
- Review of clinical data, imaging, and surgical outcomes.
- Focus on location and degree of spinal canal compression.
Main Results:
- All five patients presented with neurological deficits contralateral to the side of compression.
- Compression was caused by herniated discs or stenosis, predominantly in the low thoracic or upper lumbar spine.
- Surgical decompression resulted in immediate symptom improvement in all patients.
Conclusions:
- Eccentric spinal canal compression can cause predominantly contralateral neurological symptoms.
- Surgical intervention is effective in alleviating symptoms associated with eccentric spinal compression.
- Location of compression, even when eccentric, is a critical factor in neurological presentation.
