An ulna fracture is a break in the ulna bone, one of the two bones in the forearm. [2] It is often associated with a fracture of the other forearm bone, the radius. [1] [3]An ulna fracture can be a single break as in a so called nightstick fracture, which can be caused by someone being hit on the inside of the forearm often by a stick, notably when they are holding their arm up to protect ...
A distal radius fracture, also known as wrist fracture, is a break of the part of the radius bone which is close to the wrist. [1] Symptoms include pain, bruising, and rapid-onset swelling. [1] The ulna bone may also be broken. [1] In younger people, these fractures typically occur during sports or a motor vehicle collision. [2]

The word radius is Latin for "ray". In the context of the radius bone, a ray can be thought of rotating around an axis line extending diagonally [clarification needed] from center of capitulum to the center of distal ulna. While the ulna is the major contributor to the elbow joint, the radius primarily contributes to the wrist joint. [5]
A line drawn between the distal ends of the articular surface of the radius on a lateral X-ray. A line that is perpendicular to the diaphysis of the radius. Sometimes, the diaphysis of the radius is hard to distinguish from the ulna, and a line between them (turquoise line in image) may be used instead. [2]
Direct blow on back of upper forearm would be a very uncommon cause. In this context, isolated ulnar shaft fractures are most commonly seen in defence against blunt trauma (e.g. nightstick injury). Such an isolated ulnar shaft fracture is not a Monteggia fracture. [citation needed] It is called a 'nightstick fracture'.
The Galeazzi fracture is a fracture of the distal third of the radius with dislocation of the distal radioulnar joint.It classically involves an isolated fracture of the junction of the distal third and middle third of the radius with associated subluxation or dislocation of the distal radio-ulnar joint; the injury disrupts the forearm axis joint.
Radioulnar synostosis is a rare condition where there is an abnormal connection between the radius and ulna bones of the forearm. [1] This can be present at birth ( congenital ), when it is a result of a failure of the bones to form separately, or following an injury (post-traumatic).
