Area of Science:

  • Orthopaedic surgery
  • Pediatric radiology
  • Anatomy

Background:

  • Dr. Ernst Baumann described an angle measured from pediatric elbow radiographs.
  • Variations in defining this angle exist in orthopaedic literature.
  • Baumann's original definition and his later beliefs require clarification.

Purpose of the Study:

  • To identify and differentiate three variations of Baumann's angle.
  • To determine Baumann's original method of angle measurement.
  • To address confusion regarding the angle's relationship with the carrying angle.

Main Methods:

  • Literature review of orthopaedic articles.
  • Analysis of translations of Dr. Baumann's original publications.
  • Radiographic measurement interpretation.

Main Results:

  • Three distinct definitions of Baumann's angle were identified.
  • Baumann originally used Variation I (shaft-physeal angle).
  • Baumann incorrectly believed Variation II equaled the carrying angle.

Conclusions:

  • The definition of Baumann's angle lacks standardization.
  • The relationship between Baumann's angle and the carrying angle is complex.
  • A standardized term like 'shaft-physeal' angle is recommended to reduce confusion.
