Summary
Predictors of surgical outcomes for spinal stenosis include symptom duration and preoperative function. Identifying these factors can improve patient information and shared decision-making for better surgical results.
Area of Science:
- Neurosurgery
- Orthopedics
- Spinal Surgery
Background:
- Many patients experience persistent symptoms after spinal stenosis surgery.
- Few studies have identified predictors of surgical outcomes.
- Understanding predictors can optimize patient selection and management.
Purpose of the Study:
- To identify patient- and imaging-related predictors of surgical outcomes in spinal stenosis.
- To correlate preoperative factors with clinical outcomes 1 year after surgery.
Main Methods:
- Prospective follow-up of 109 patients undergoing decompression without fusion for central spinal stenosis.
- Clinical outcome assessment using EQ-5D, Oswestry disability index, walking distance, and pain levels (VAS).
- MRI analysis included dural sac area, number of stenosis levels, and spondylolisthesis; multivariable analyses were performed.
Main Results:
- Longer duration of leg pain (>2 years) predicted worse outcomes in pain, function, and quality of life.
- Preoperative low function and low EQ-5D scores predicted poorer outcomes.
- Narrower dural sac area correlated with greater improvement in back pain and lower leg pain.
Conclusions:
- Symptom duration and preoperative function are key predictors of spinal stenosis surgery outcomes.
- These modifiable factors can inform preoperative patient counseling and shared decision-making.
- Findings support personalized surgical planning for spinal stenosis.
