Ulna and Radius Fractures: What You Need to Know. The forearm is made up of two bones, the ulna and the radius. A forearm fracture can occur in one or both of the forearm bones. Some of the causes include falls on the forearm or outstretched arm and direct impact from an object to the forearm.
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]
The radius and ulna are two long bones in the forearm. People may experience fractures in one or both bones after a fall. Surgery may be necessary in some cases. Learn more here.
Radius and ulnar shaft fractures, also known as adult both bone forearm fractures, are common fractures of the forearm caused by either direct trauma or indirect trauma (fall). Diagnosis is made by physical exam and plain orthogonal radiographs.
Fractures of the forearm can occur near the wrist at the farthest (distal) end of the bone, in the middle of the forearm, or near the elbow at the top (proximal) end of the bone. This article focuses on fractures that occur in the middle segments of the radius and ulna.
A broken arm happens when any of the three bones in your arm are fractured. It’s more common to break one of the two bones in your forearm (your ulna and radius), but severe traumas like falls and car accidents can break your upper arm bone (humerus). Most people need to wear a cast for several weeks while their arm heals.
Fractures of the radius and ulna are the most common fractures of the upper extremity, with distal fractures occurring more often than proximal fractures.
Your arm is made up of three bones: the upper arm bone (humerus) and two forearm bones (the ulna and the radius). The term "broken arm" may refer to a fracture in any of these bones. A broken arm involves one or more of the three bones in your arm — the ulna, radius and humerus.
Ulnar Shaft Fractures . An isolated fracture to the ulna often called a "nightstick" fracture, most often occurs during an altercation. When someone defending themselves raises their forearm in a protective posture, the ulna bone is exposed and can be damaged from a blunt traumatic exposure.
Proximal ulna fractures are relatively common upper limb injuries, which may represent fragility fractures or result from high-energy trauma. These include fractures of the olecranon, coronoid and associated radial head dislocations.
