Triangular osteosynthesis effectively treats vertically unstable sacral fractures, allowing early weight-bearing and aiding nerve recovery. This surgical technique demonstrates rigid fixation and good functional outcomes in patients.

Area of Science:

  • Orthopedic surgery
  • Traumatology
  • Spine surgery

Background:

  • Vertically unstable sacral fractures pose significant treatment challenges.
  • Effective surgical stabilization is crucial for patient recovery and functional outcomes.

Purpose of the Study:

  • To evaluate the operative technique and effectiveness of triangular osteosynthesis for vertically unstable sacral fractures.
  • To assess the clinical and radiographic outcomes of this surgical approach.

Main Methods:

  • A prospective study of 22 patients with 25 vertically unstable sacral fractures treated with triangular osteosynthesis (universal spine system and iliosacral screw).
  • Patients underwent clinical and radiographic follow-up, with reduction quality assessed by Matta criteria and functional outcomes by Majeed and Gibbons criteria.

Published on: September 16, 2022

Main Results:

  • All fractures achieved bone union with an average follow-up of 14 months.
  • Excellent or good fracture reduction was achieved in 24 out of 25 cases.
  • Good to excellent functional outcomes were reported in 19 out of 21 cases, with significant improvement in neurologic impairment.

Conclusions:

  • Triangular osteosynthesis provides rigid fixation for vertically unstable sacral fractures.
  • This technique allows for early full weight-bearing and facilitates nerve decompression, promoting functional recovery.
