Summary
Surgical decompression can reverse chronic severe thoracic spinal stenosis causing myelopathy. Early intervention and complete decompression are key factors for successful surgical outcomes in these patients.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Neurology
Background:
- Thoracic spinal stenosis can lead to severe myelopathy.
- Understanding causes and outcomes is crucial for patient management.
Purpose of the Study:
- To identify causes of thoracic spinal stenosis leading to myelopathy.
- To evaluate surgical results and prognostic factors for myelopathy.
- To determine factors influencing surgical outcomes.
Main Methods:
- Retrospective analysis of 28 cases with thoracic spinal stenosis and myelopathy.
- Surgical interventions included decompressive laminectomy, anterior decompression, or combined approaches.
- Statistical analysis (chi-squared test, general linear model) was used to identify outcome predictors.
Main Results:
- Neurological improvement was observed in 16 patients, with an average Nurick grade reduction.
- Symptom duration under 2 years correlated with better outcomes (P=0.006).
- Sufficient decompression and absence of proximal stenosis improved treatment success (P=0.005, P=0.002).
Conclusions:
- Thoracic spinal stenosis causing myelopathy is potentially reversible with surgical decompression.
- Optimal surgical outcomes depend on early symptom duration, extent of decompression, and absence of additional stenosis.
