Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Oncology

Background:

  • Osteosarcoma resection presents significant surgical challenges due to tumor location and proximity to vital tissues.
  • High rates of postoperative complications are associated with traditional osteosarcoma resection techniques.

Purpose of the Study:

  • To develop and evaluate patient-specific surgical guides for precise osteosarcoma resection.
  • To improve surgical accuracy, minimize complications, and enhance patient outcomes in osteosarcoma treatment.

Main Methods:

  • Utilized computer-aided design (CAD) based on patient CT and MRI scans to create custom surgical templates.
  • Employed 3D printing technology to fabricate the patient-specific guiding templates for intraoperative use.

Main Results:

  • Guided surgeries demonstrated more precise tumorous bone resection and accurate bone implant placement.
  • Observed reductions in intraoperative blood loss, operation time, and radiation exposure.
  • Patients achieved favorable recovery, with a mean Musculoskeletal Tumor Society score of 27.125.

Conclusions:

  • Patient-specific 3D-printed guides significantly enhance precision in osteosarcoma resection surgery.
  • This computer-aided approach offers a promising method for improving surgical outcomes and patient recovery in osteosarcoma treatment.
