Summary
This study presents a novel technique for reconstructing the lumbosacral junction after total sacrectomy for osteosarcoma. A custom-made prosthesis, designed using a 3D model, enabled successful reconstruction and functional recovery in a patient.
Area of Science:
- Orthopedic surgery
- Surgical oncology
- Biomedical engineering
Background:
- Total sacrectomy for highly malignant osteosarcoma presents significant reconstruction challenges.
- Previous reconstruction methods lack detailed pre-operative planning and custom prosthesis design.
- A three-dimensional (3D) real-sized model offers a novel approach for pre-operative planning and prosthesis design.
Observation:
- A 42-year-old female patient presented with neurologic impairment due to sacral osteosarcoma invading surrounding structures.
- A 3D real-sized model was utilized for surgical planning and the design of a custom sacral prosthesis.
- The patient underwent a staged anteroposterior resection-reconstruction procedure.
Findings:
- The custom-made sacral prosthesis successfully restored spinopelvic continuity after total sacrectomy.
- The patient achieved disease-free status at 36-month follow-up with a stable, painless spinopelvic junction.
- Functional outcomes included the ability to walk short distances with orthoses and crutches.
Implications:
- 3D modeling is advantageous for planning total sacrectomy and designing custom prostheses.
- This technique facilitates achieving wide bony resection margins and stable reconstruction.
- The approach holds promise for improving outcomes in complex sacral tumor resections.
