  • To simplify and improve the precision of lower limb deformity correction using external fixators.

Main Methods:

  • Developed digital measurement techniques based on Paley's method.
  • Created deformity correction algorithms and electronic prescription software.
  • Utilized 3D simulation with virtual reality modeling language.
  • Treated 15 patients with complex lower limb deformities using the developed software and parallel external fixators.

Main Results:

  • Mean follow-up was 15 months; average frame fixation duration was 8.4 months.
  • All patients reported satisfaction with corrected limb alignment.
  • No wound infections or complications were observed during treatment.

Conclusions:

  • Computer-aided parallel external fixator systems offer satisfactory outcomes for lower limb deformity correction.
  • The digitized and simplified correction process enhances clinical application.
