[The anconeus muscle. Anatomical and electromyographic study]
Bulletin De L'Association Des Anatomistes
|September 1, 1984
Summary
The anconeus muscle extends the elbow, pronates the forearm, and stabilizes the elbow joint. This study clarifies its role in forearm and wrist movements, challenging previous assumptions.
Area of Science:
- Anatomy
- Biomechanics
- Kinesiology
Context:
- The anconeus muscle's function has been debated since Duchenne de Boulogne's initial studies.
- Previous research lacks comprehensive anatomical and functional data.
Purpose:
- To clarify the anatomical and functional roles of the anconeus muscle.
- To provide evidence for the anconeus muscle's contribution to elbow and forearm movements.
Summary:
- Anatomical dissection of 10 cadavers and electromyographic analysis of 10 living subjects (ages 18-47) were performed.
- The anconeus muscle was identified as an elbow extensor and forearm pronator.
- It also mobilizes the ulna in adduction, aiding elbow stabilization and wrist ulnar deviation, potentially acting as a dynamic lateral elbow ligament.
Impact:
- Revises understanding of the anconeus muscle's function in elbow and forearm biomechanics.
- Highlights the anconeus muscle's significance in joint stability and complex movements.
- Provides foundational data for further research in upper limb kinematics and injury rehabilitation.
