Computerized fluoroscopic navigation reduces radiation exposure during percutaneous pelvic fracture fixation. This advanced technique enhances surgical precision for improved patient outcomes.

Area of Science:

  • Orthopedic Surgery
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Percutaneous internal fixation of pelvic fractures offers rapid mobilization and reduced morbidity.
  • Conventional fluoroscopy in these procedures poses significant radiation risks to patients and surgeons.

Purpose of the Study:

  • To evaluate the efficacy of computerized fluoroscopic navigation in percutaneous pelvic fracture fixation.
  • To assess radiation reduction and precision improvements using this navigation system.

Main Methods:

  • Computerized fluoroscopic navigation was employed for percutaneous insertion of 45 cannulated screws in 29 patients.
  • Screws included sacroiliac, pubic ramus, posterior column, and supraacetabular transverse types.
  • Preliminary fluoroscopic views were taken from a distance, with no further intraoperative fluoroscopy.

Main Results:

  • Screw placement accuracy was within 2 mm and 5 degrees.
  • The system demonstrated potential for significant fluoroscopic radiation time savings.
  • Improved procedural precision was observed.

Conclusions:

  • Computerized fluoroscopic navigation is a viable tool for reducing radiation exposure in percutaneous pelvic fracture fixation.
  • The system enhances procedural precision, making it suitable for selected patients.
  • This technology represents an advancement in minimally invasive orthopedic trauma surgery.
