The ulna is a long bone in the forearm. It lies medially and parallel to the radius, the second of the forearm bones. The ulna acts as the stabilising bone, with the radius pivoting to produce movement. Proximally, the ulna articulates with the humerus at the elbow joint. Distally, the ulna articulates with the radius, forming the distal radio-ulnar joint. In this article, we shall look at the ...
Bone marrow failure syndromes can be associated with abnormalities of the forearms. We observed a neonate with congenital thrombocytopenia who had bilateral radio-ulnar synostosis and fifth finger ...
The ulna is a long bone found in the forearm that stretches from the elbow to the wrist, and when in standard anatomical position, is found on the medial side of the forearm. It is broader close to the elbow, and narrows as it approaches the wrist. Close to the elbow, the ulna has a bony process, the olecranon process, a hook-like structure that fits into the olecranon fossa of the humerus ...
The ulna is the longer of the two bones in your forearm. It helps you move your arm, wrist and hand.

The radius and ulna are the two bones of the forearm. Learn all about their anatomy at Kenhub!
The ulna and radius are the two long bones of the forearm, working together to facilitate a wide range of movements in the arm and hand. Positioned with the ulna on the medial side and the radius on the lateral side, these bones are connected by an interosseous membrane, ensuring coordinated function. Their anatomical structure is critical for professionals in fields like orthopedics, physical ...
