Area of Science:

  • Orthopedic surgery
  • Radiology
  • Anatomy

Background:

  • Transsacral screw fixation is crucial for posterior pelvic injuries.
  • Anatomical variations in sacral segmentation can compromise screw placement safety.
  • A reliable method to assess safe screw corridors is needed.

Purpose of the Study:

  • To develop and validate an automated 3D technique for determining transsacral screw safe zones.
  • To analyze the influence of gender and sacral segmentation variations on safe zone size.
  • To establish anatomical parameters for safe screw insertion in the upper sacral segments.

Main Methods:

  • Automated 3D analysis of 526 adult pelvis CT scans.
  • Quantification of safe zone size for transsacral screws in S1 and S2.
  • Comparison of safe zone sizes based on gender, neuroforamen count, and lumbosacral transitional vertebrae (LSTV) presence.
  • Utilized a 10 mm safety threshold for screw diameter.

Main Results:

  • Safe zone size was significantly influenced by gender, neuroforamen number, and LSTV presence (p < 0.001).
  • Sacral segmentation variations (3, 4, or 5 neuroforamen; presence/absence of LSTV) affected safe corridor dimensions.
  • 17% of non-LSTV sacra and 74% of LSTV sacra had inadequate S2 safe zones.
  • Only 4% of sacra could not accommodate a safe screw in either S1 or S2.

Conclusions:

  • Automated 3D analysis provides predictable insights into transsacral screw safe zones.
  • Gender and sacral segmentation variations are critical factors in planning safe screw placement.
  • This technique aids surgeons in optimizing screw trajectory for posterior pelvis fixation, minimizing risks associated with anatomical anomalies.
