Summary
Preoperative instability and female sex predict poor outcomes in spinal stenosis surgery. Postoperative slipping correlates significantly with unsatisfactory results after decompression without fusion.
Area of Science:
- Neurosurgery
- Orthopedics
- Spinal Surgery
Background:
- Spinal stenosis is a common condition requiring surgical intervention.
- Surgical decompression without fusion is a treatment option for spinal stenosis.
- Predictors of surgical outcomes require further investigation.
Purpose of the Study:
- To identify factors predicting outcomes in patients undergoing spinal stenosis surgery without fusion.
- To evaluate the impact of preoperative instability and patient demographics on surgical results.
- To assess the relationship between postoperative instability (slipping) and patient satisfaction.
Main Methods:
- Retrospective study of 61 patients operated on for spinal stenosis without fusion.
- Functional myelography used to assess preoperative instability.
- Analysis of patient demographics, surgical procedures, and postoperative outcomes.
Main Results:
- Preoperative instability was a significant predictor of poor prognosis (P < 0.01).
- Female patients experienced less favorable outcomes (P < 0.05).
- Postoperative slipping occurred in 26 patients and was strongly associated with unsatisfactory results (P < 0.001).
Conclusions:
- Preoperative instability is a critical factor for poor outcomes in spinal stenosis surgery without fusion.
- Female sex is associated with less favorable surgical results.
- Postoperative slipping is a significant complication linked to dissatisfaction after decompression surgery.
