An artificial intelligence (AI) system for screening hip dysplasia demonstrates high diagnostic performance. This AI tool effectively analyzes pelvic radiographs, outperforming general orthopaedic residents in identifying hip dysplasia.

Area of Science:

  • Orthopaedic Surgery
  • Artificial Intelligence
  • Medical Imaging

Background:

  • Hip dysplasia diagnosis relies on radiographic assessment of acetabular coverage.
  • Accurate and timely diagnosis is crucial for effective treatment and improved patient outcomes.
  • Current screening methods may benefit from enhanced diagnostic tools for wider clinical application.

Purpose of the Study:

  • To develop and evaluate an AI-based radiographic screening system for hip dysplasia.
  • To assess the diagnostic performance and clinical utility of the AI system.
  • To compare the AI system's performance against human expert assessments and general orthopaedic residents.

Main Methods:

  • Development of an AI system using DeepLabCut and U-Net models for landmark detection and parameter quantification on pelvic radiographs.

  • Training and validation datasets comprised radiographs from patients with hip dysplasia and asymptomatic volunteers.
  • Ground-truth measurements and diagnoses were established through assessments by hip surgeons and non-specialist clinicians.

    • Main Results:

    • The AI system achieved good to excellent agreement with ground-truth measurements (Intraclass Correlation Coefficient: 0.70-0.95).
    • The AI system demonstrated superior screening performance compared to general orthopaedic residents (Sensitivity: 0.96 vs. 0.44-0.97; Specificity: 0.92 vs. 0.16-0.92; AUC: 0.94 vs. 0.57-0.76; F-measure: 0.96 vs. 0.60-0.81).
    • The AI system effectively learned anatomical structures from a relatively small dataset.

    Conclusions:

    • The developed AI system shows significant potential as a radiographic screening tool for hip dysplasia.
    • It can serve as a valuable referral-support tool for primary care clinicians and non-specialists.
    • The AI system offers high diagnostic accuracy and clinical utility, even with limited training data.
