Summary
Navigated multiplanar osteotomies precisely resected 14 spinal bone tumors. This technique improved safety and accuracy for both malignant and benign primary spinal bone tumors (SPBT).
Area of Science:
- Spine Surgery
- Oncology
- Orthopedic Oncology
Background:
- Spinal primary bone tumors (SPBT) require accurate diagnosis and treatment for cures.
- Malignant or aggressive benign SPBT often necessitate en bloc resection.
- Multiplanar osteotomies can help preserve critical structures and nerve function.
Purpose of the Study:
- To report the planning and execution of navigated multiplanar osteotomies.
- To achieve en bloc resection for 14 cases of SPBT.
Main Methods:
- Retrospective analysis of 14 consecutive patients (2014-2019) with SPBT.
- Utilized preoperative 3D planning and intraoperative navigation.
- Performed en bloc resection using multiplanar osteotomies, with a minimum 12-month follow-up.
Main Results:
- Diagnoses included 11 primary sarcomas (6 chordomas, 5 chondrosarcomas) and 3 osteoblastomas.
- Tumors were located in the sacrum (11) and thoracic spine (3).
- En bloc margins were marginal (<1 cm) in 12 patients and wide (>1 cm) in 2. Forty osteotomies were performed using navigation.
Conclusions:
- Navigated multiplanar osteotomies enhance precision and safety in en bloc resection of SPBT.
- This technique is effective for both malignant and benign/locally aggressive spinal tumors.
