Summary
This study reveals significant sex-based differences in elbow carrying angle and alignment within the Central Indian population. These findings are crucial for understanding upper limb biomechanics and variations in elbow morphometry.
Area of Science:
- Orthopedics
- Biomechanics
- Radiology
Background:
- The carrying angle of the elbow is vital for upper limb biomechanics, affecting arm movement and hand precision.
- Understanding normal elbow morphometry and its variations is essential for clinical applications.
Purpose of the Study:
- To assess elbow joint parameters, including carrying angle, articular surface angle, and anatomical alignment.
- To investigate variations in elbow morphometry based on age, sex, and side dominance.
Main Methods:
- 300 healthy volunteers (aged 18-50) underwent anteroposterior (AP) and lateral elbow radiography.
- Measurements included carrying angle, articular surface angle, anterior humeral line (AHL), and radiocapitellar line (RCL).
Main Results:
- Significant sex-based differences were observed in the carrying angle (males: 10.19° dominant, 9.72° non-dominant; females: 13.44° dominant, 13.38° non-dominant).
- The articular surface angle averaged 82.8°.
- AHL intersected the capitellum in the middle third for over 55% of participants on both sides.
Conclusions:
- This study provides key anthropometric data for the Central Indian population.
- Significant sex-based differences in elbow carrying angle and alignment were identified.
