Area of Science:

  • Orthopedic surgery
  • Medical imaging analysis
  • Biostatistics

Background:

  • Image analysis is crucial in orthopedics but faces challenges like anonymization, bias, and observer efficiency.
  • Existing software solutions for these challenges are inadequate.

Purpose of the Study:

  • To evaluate the validity and efficiency of Tyche, a novel free online tool for orthopedic image analysis.
  • To compare Tyche's performance against a validated software tool for measuring inter- and intraobserver agreement.

Main Methods:

  • One hundred pelvic radiographs were analyzed by five orthopedic surgeons using Tyche and a validated software.
  • Measurements included common orthopedic modalities and scores.
  • Statistical comparison involved intra-class correlations, Fleiss' kappa coefficients, and Bland-Altman plots.

Main Results:

  • Tyche demonstrated significant correlations (r=0.17 to 0.99) for inter- and intraobserver agreement, comparable to the validated tool.
  • Bland-Altman plots confirmed the non-inferiority of Tyche.
  • Image analysis was significantly faster using Tyche.

Conclusions:

  • Tyche is a valid and efficient tool for orthopedic image analysis.
  • Tyche is suitable for determining inter- and intraobserver agreements, multicenter studies, and score validations.
