A study published in the Journal of Spinal Disorders and Techniques examines the long-term outcomes after revision neural decompression and fusion for same-level recurrent lumbar stenosis.
The study includes 53 patients who underwent revision neural decompression and instrumented fusion for same-level recurrent stenosis-associated back and leg pain. The researchers found:
1. The average time between the index and revision surgery was around four years.
2. There was a significant improvement from the baseline BP-VAS score, LP-VAS and ODI scores after surgery:
• BP-VAS: 9.28±1.01 vs. 5±2.94
• LP-VAS: 9.55±0.93 vs. 3.45±2.95
• ODI: 36.02±6.01 vs. 21.75±12.08
3. Additional improvements were recorded in these scores:
• SD SF-12 PCS: 7.17±11.22
• SF-12 MCS: 12.57±13.03
• ZDS: 12.37±15.80
• EQ-5D: 0.42±0.34
4. The average two-year gain in health utility state was 0.84 quality-adjusted life years.
5. Patients spent on average six months on postoperative narcotics and missed work for six months. "Our study suggests that revision neural decompression and instrumented fusion for recurrent same-level stenosis provides significant improvement in all patient-assessed outcome metrics and should be offered as a viable treatment option," concluded the study authors.
