Summary
This study details the multisegmental total en bloc spondylectomy technique for aggressive spinal tumors. The goal is achieving tumor-free margins, spinal stability, and preserving neurological function.
Area of Science:
- Spine surgery
- Surgical oncology
- Oncology
Context:
- Multilevel en bloc excision of vertebral tumors (multisegmental total en bloc spondylectomy) is a complex procedure.
- Achieving tumor-free margins and restoring spinal stability are critical for patient outcomes.
Purpose:
- To describe the surgical technique and principles for en bloc excision of vertebral tumors.
- To outline approaches for tumor removal, spinal reconstruction, and functional preservation.
Summary:
- The technique involves sequential anterior and posterior approaches for tumor release and spinal reconstruction.
- Pedicle screw instrumentation, autologous bone grafting with carbon-composite cages, and stabilization are key components.
- Postoperative management includes intensive care and adjuvant therapies based on resection margins.
Impact:
- Enables complete tumor removal with clear margins for aggressive spinal tumors.
- Aims to restore biomechanical stability and preserve or regain neurological function.
- Minimizes the risk of local and systemic tumor recurrence through radical resection.
