Insights

Accurate pelvic external fixator placement in children is challenging due to narrow iliac crests. Preoperative 3D CT planning with a functional pelvic plane reference improved half-pin insertion accuracy in a pediatric pelvic fracture case.

Area of Science:

  • Orthopedic surgery
  • Pediatric trauma
  • Medical imaging

Background:

  • Secure fixation using half-pins in the iliac crest is crucial for pelvic external fixators.
  • Iliac bone thickness varies, complicating accurate half-pin insertion, especially in pediatric pelvises which are narrower than adult pelves.

Observation:

  • A case involving a pediatric pelvic fracture requiring external fixation is presented.
  • Difficulty in accurate half-pin insertion was noted due to anatomical variations in the pediatric iliac crest.

Findings:

  • Preoperative planning using three-dimensional computed tomography (3D CT) was employed.
  • An intraoperative support device referencing the functional pelvic plane enabled accurate preoperative planning for half-pin insertion.

Implications:

  • This approach demonstrates the potential for improved accuracy in pediatric pelvic external fixation.
  • 3D CT-based planning can enhance surgical outcomes for complex pediatric pelvic fractures.
  • The functional pelvic plane serves as a valuable reference for precise surgical navigation.
