Summary
Surgical management of sacral tumors involves complex sacrectomy and spinopelvic reconstruction. This article details a step-by-step technique for en bloc tumor extirpation and reconstruction, aiding spine surgeons.
Area of Science:
- Orthopedic Surgery
- Neurosurgery
- Surgical Oncology
Background:
- Sacral tumors necessitate challenging partial or total sacrectomy and spinopelvic reconstruction.
- Many spine surgeons lack familiarity with the specialized techniques required for these complex procedures.
Purpose of the Study:
- To describe a detailed, step-by-step operative technique for the surgical management of sacral tumors.
- To provide essential illustrations to guide surgeons through the complex procedures.
Main Methods:
- Sequential anterior and posterior approaches for total sacrectomy.
- Intraperitoneal anterior approach for tumor exposure, vessel ligation, and partial sacrectomy.
- Rectus abdominis myocutaneous flap reconstruction and posterior sacrectomy, followed by spinopelvic fixation (modified Galveston or double iliac screw fixation).
Main Results:
- En bloc extirpation of the sacrum with tumor was achieved.
- Successful spinopelvic reconstruction using established fixation techniques was performed.
- Closure was completed with a myocutaneous flap.
Conclusions:
- The described technique provides a viable approach for sacral tumor resection and reconstruction.
- Understanding disease characteristics and biomechanics is crucial for selecting appropriate surgical treatments for sacral tumors.
