Schon's radiographic classification reliably categorizes Charcot midfoot deformities by type and severity. This system aids in diagnosis, treatment planning, and prognosis assessment for midfoot collapse.

Area of Science:

  • Orthopaedic Surgery
  • Radiology
  • Podiatry

Background:

  • Charcot midfoot deformities present complex challenges in diagnosis and management.
  • Existing classification systems may lack objective criteria for severity staging.

Purpose of the Study:

  • To introduce and validate Schon's radiographic classification system for Charcot midfoot deformities.
  • To assess the reliability and reproducibility of this new classification system.

Main Methods:

  • A four-type radiographic classification (I-IV) based on anatomical location was applied.
  • An objective severity staging (alpha-beta) was introduced using specific radiographic angles and dislocation presence.
  • The system was tested on 75 orthopaedic surgeons for interobserver and intraobserver reliability.

Main Results:

  • The classification demonstrated high interobserver reliability (81%) and intraobserver reproducibility (97%).
  • Foot and ankle fellows achieved the highest scores, followed by residents, with attending surgeons scoring lowest.
  • The most frequent error involved misclassifying type I as type II deformities.

Conclusions:

  • Schon's classification system effectively categorizes Charcot midfoot deformities by anatomical type and severity.
  • The system exhibits high reliability and reproducibility, making it a valuable tool for clinical practice.
  • This classification can enhance diagnosis, guide treatment strategies, and improve prognostic accuracy.
