Bones of the forearm - Radius and ulna (preview) - Human Anatomy | Kenhub
Kenhub - Learn Human Anatomy・2 minutes read
Fractures of the distal forearm are more common than wrist fractures in children, typically affecting the bones of the forearm rather than the wrist directly, with the ulna positioned medially and the radius laterally, forming joints with the humerus and ulna at different points.
Insights
- Fractures in children's distal forearms are significantly more common than wrist fractures, often affecting the forearm bones rather than the wrist bones specifically.
- The radius and ulna, the two bones in the forearm, have distinct positions - the ulna is on the inner side, while the radius is on the outer side, both playing crucial roles in articulating with the humerus and each other.

Child Forearm Fractures: Ulna and Radius
- Fractures of the distal forearm are almost three times more common in children than fractures to the actual bones of the wrist, with injuries often isolated to the bones of the forearm rather than the wrist itself.
- The ulna is found along the medial aspect of the forearm, while the radius is located on the lateral side, with the palm facing forwards in the anatomical position.
- The radius, the shorter of the two forearm bones, articulates proximally with the humerus at the capitulum, and with the ulna both proximally and distally, featuring a concave proximal articular surface that articulates with the humerus and the ulna at the radial notch forming the proximal radioulnar joint.
