Summary
We developed total en bloc spondylectomy (TES), a posterior surgical technique for solitary metastatic vertebral tumors. This radical, two-part resection offers oncological wide margins for improved local tumor control.
Area of Science:
- Oncology
- Neurosurgery
- Spinal Surgery
Background:
- Metastatic vertebral tumors present a significant challenge in oncological treatment.
- Surgical resection is crucial for local control and improving patient outcomes.
Purpose of the Study:
- To describe and evaluate the surgical technique of total en bloc spondylectomy (TES) through a posterior approach.
- To assess the efficacy of TES in achieving local curability for solitary metastatic vertebral tumors.
Main Methods:
- Development of a two-step posterior surgical technique: en bloc laminectomy with spinal instrumentation followed by en bloc corpectomy and prosthesis replacement.
- Application of TES in a cohort of 72 patients with malignant vertebral tumors.
Main Results:
- The total en bloc spondylectomy (TES) procedure was successfully performed in 72 patients.
- Local recurrence was observed in only three patients, indicating a high rate of local tumor control.
Conclusions:
- Total en bloc spondylectomy (TES) is a radical and effective surgical method for managing solitary metastatic vertebral tumors.
- The posterior approach for TES allows for oncological wide margins, contributing to the procedure's success in achieving local curability.
