Tandem spinal stenosis (TSS) surgery outcomes favor staged decompression, especially cervical-first, for optimal functional improvement. Individualized treatment algorithms are crucial for managing this complex spinal condition.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Orthopedics
Background:
- Tandem spinal stenosis (TSS) involves noncontiguous spinal regions requiring complex surgical decisions.
- Current management lacks a standardized algorithm for simultaneous versus staged decompression.
Purpose of the Study:
- To compare the effectiveness of simultaneous and staged surgical decompression for TSS.
- To identify optimal surgical strategies based on patient outcomes and comorbidities.
Main Methods:
- Systematic review and meta-analysis of PRISMA-guided studies.
- Searched PubMed, Scopus, and EMBASE for TSS surgical outcomes.
- Analyzed 1,006 interventions from 12 eligible studies.
Main Results:
- Overall significant improvement in Japanese Orthopaedic Association scores post-surgery.
- Staged cervical-first surgery yielded the greatest functional improvement (SMD, 4.31).
- Simultaneous surgery showed moderate improvement (SMD, 2.65); lumbar-first staged surgery had negligible gains.
Conclusions:
- Individualized surgical strategy is essential for TSS.
- Prioritize staged cervical decompression for myelopathy; consider simultaneous decompression for suitable patients without myelopathy.
- A proposed algorithm guides decision-making based on symptoms, myelopathy, and comorbidities.
