Modified spinopelvic crab-shaped fixation using offset connectors for a H-shaped sacral fracture with a floating Roy-Camille type 3 transverse component: a case report

AOAkinori OkudaKMKeisuke MasudaHKHironobu Konishi

Key Points

  • To evaluate the effectiveness of modified crab-shaped fixation using offset connectors in complex sacral fractures.
  • Utilized modified crab-shaped fixation with offset connectors as dorsal buttresses.
  • Applied the technique to an H-shaped sacral fracture with a floating transverse component.
  • Monitored alignment and stability until union.
  • Achieved stable reduction of the fracture.
  • Maintained alignment throughout the healing process.
  • Showed a successful outcome where traditional methods were not feasible.

Abstract

Modified crab-shaped fixation using offset connectors as dorsal buttresses can provide stable reduction and maintain alignment until union in complex spinopelvic dissociation patterns where standard constructs or transiliac transsacral screw (TITSS) are not feasible.
