Summary

Computer-assisted preoperative planning (CAPP) enhances surgical treatment by using patient data for precise, real-dimension calculations. This method proved excellent for planning corrective osteotomies, improving patient outcomes.

Area of Science:

  • Orthopedic Surgery
  • Medical Imaging
  • Computer-Aided Design

Background:

  • Computer-assisted preoperative planning (CAPP) integrates CAD principles and expert knowledge for surgical decision support.
  • CAPP systems utilize patient-specific data to generate precise, real-world dimensional instructions for operations.

Purpose of the Study:

  • To present the first CAPP application for preoperative planning of corrective osteotomy in malunited distal radius fractures.
  • To evaluate the efficacy of CAPP in guiding surgical treatment for complex wrist fractures.

Main Methods:

  • Developed a CAPP system using three-dimensional wire models derived from two orthogonal X-ray projections.
  • Simulated corrective osteotomy on digital models of affected wrists until optimal fit was achieved.

  • Utilized real-dimension calculations for surgical treatment guidelines.

    • Main Results:

    • The CAPP system successfully simulated corrective osteotomies for malunited distal radius fractures.
    • Numerical outputs from the CAPP system served as effective surgical treatment guidelines.
    • Excellent results were observed in a cohort of 33 patients undergoing CAPP-guided surgery.

    Conclusions:

    • Computer-assisted preoperative planning is a viable and effective approach for complex orthopedic procedures.
    • The use of real-dimension calculations in CAPP is critical for accurate surgical guidance.
    • This CAPP application demonstrated superior outcomes for corrective osteotomy of distal radius fractures.
