A novel spinal-pelvic instrumentation allows patient mobilization after sacrectomy. This implant stabilizes the spine to the pelvis, enabling ambulation, even without assistive devices.

Area of Science:

  • Orthopedic Surgery
  • Spinal Surgery
  • Biomedical Engineering

Background:

  • Sacrectomy necessitates stable spinal-pelvic fusion for patient mobilization.
  • Existing methods may not provide adequate stability after extensive sacral resection.
  • Restoring functional mobility is crucial for post-operative recovery.

Observation:

  • A new instrumentation system was developed to achieve spinal-pelvic fixation.
  • The system utilizes dual DHS screws in the pelvis and an internal spine fixator anchored in L3 and L4.
  • Two patients with sacrectomy underwent stabilization using this novel implant.

Findings:

  • The developed instrumentation successfully stabilized the spine to the pelvis in both patients.
  • One patient achieved ambulation with crutches post-operatively.

  • The second patient regained independent ambulation without any walking aids.

    • Implications:

    • This spinal-pelvic fixation technique offers a viable solution for restoring mobility after sacrectomy.
    • The implant design shows promise in improving functional outcomes and patient independence.
    • Further research could explore the long-term efficacy and broader applicability of this instrumentation.
