radiocapitellar joint
The articulation between the radial head and the capitellum of the humerus in the elbow.
Full Definition
The radiocapitellar joint is one of three articulations within the elbow joint complex, formed by the convex radial head articulating with the concave capitellum of the lateral humeral condyle. This joint allows for flexion-extension and pronation-supination movements of the forearm. In orthopedic practice, radiocapitellar joint pathology includes fractures, dislocations, and degenerative changes that can significantly impact elbow function and require specialized surgical techniques.
Usage
Usage note: Hyphenate when used as an adjective (radiocapitellar-joint pathology).
