Summary
The arcade of Struthers, a potential cause of ulnar nerve compression, was investigated. Anatomical dissection revealed this arcade does not exist as a distinct anatomical structure.
Area of Science:
- Anatomy
- Surgical Anatomy
- Upper Extremity Anatomy
Background:
- The arcade of Struthers is theorized as a cause of ulnar nerve compression.
- Previous studies and clinical experience have questioned the existence of this arcade.
Purpose of the Study:
- To conduct an anatomical investigation to determine the existence of the arcade of Struthers.
- To clarify the anatomical basis of ulnar nerve compression in the upper arm.
Main Methods:
- Dissection of ten fresh frozen cadaver arms.
- Detailed examination of fascial layers on the medial aspect of the upper arm.
- Assessment of the medial intermuscular septum and its relationship with the ulnar nerve.
Main Results:
- The arcade of Struthers was not identified in any of the dissected specimens.
- No distinct fascial band consistent with the described arcade was observed.
Conclusions:
- The arcade of Struthers is not a recognized anatomical structure.
- The concept of the arcade of Struthers may be a man-made construct rather than a naturally occurring anatomical entity.
