The forearm consists of two bones, the radius and the ulna, with the ulna is located on the pinky side and the radius on your thumb side.
Is radius in front of ulna?
The radius is part of two joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch. At the wrist, the radius forms a joint with the ulna bone….Radius (bone)

Where is the radius and ulna located in the arm?
forearm
The radius and ulna are long bones that make up the forearm, extending from the elbow to the wrist. In the anatomical position, the radius is found in the lateral forearm, while the ulna is found in the medial forearm.
How long does a broken ulna and radius take to heal?
They take an average of 3-6 months to completely heal. By six weeks, patients are extremely comfortable and usually are released to full activities such as manual labor, skiing and motocross by three to four months. Aggressive return to activity too early can result in re-fracture, hardware breakage or non-union.
Which one is bigger ulna or radius?
The radius is often thought of as the larger of the two long bones in the forearm because it is thicker than the ulna at the wrist, but it is thinner at the elbow. The ulna is longer than the radius by about an inch in most people, but lengths vary considerably.
Which side is your ulna on?
The ulna is located on the opposite side of the forearm from the thumb. It joins with the humerus on its larger end to make the elbow joint, and joins with the carpal bones of the hand at its smaller end. Together with the radius, the ulna enables the wrist joint to rotate.
Which bone is stronger ulna or radius?
The ulna, along with the larger and stronger radius, makes up the forearm. Being longer and thinner, the ulna is often more easily fractured as a result of trauma. The upper end (the head) of the ulna meets with the lower end of the humerus and one side of the radius.
What is the top of the forearm called?
These usually run on the anterior face of the radius and ulna down the whole forearm. The main superficial veins of the forearm are the cephalic, median antebrachial and the basilic vein….Muscles.

What’s the outside of your forearm called?
The radius is located on the lateral side of the forearm between the elbow and the wrist joints.
How do you tell if your ulna is fractured?
Signs and symptoms include:
- Severe pain, which might increase with movement.
- Swelling.
- Bruising.
- Deformity, such as a bent arm or wrist.
- Inability to turn your arm from palm up to palm down or vice versa.
Is it easy to break your ulna?
Because of the strong force required to break the radius or ulna in the middle of the bone, it is more common for adults to break both bones during a forearm injury.
What muscles attach to the ulna?
The following muscles originate from the ulna[19][20]:
- Pronator teres – the medial surface of the coronoid process.
- Flexor carpi ulnaris – olecranon process.
- Flexor digitorum superficialis – coronoid process.
- Flexor digitorum profundus – anteromedial surface.
- Pronator quadratus – distal anterior shaft.
How long does a broken radius and ulna take to heal?
What happens if you break your radius and ulna?
When the radius and ulna are broken, a number of nearby structures can also be injured. These include the cartilage lining the surfaces of the wrist joint, nerves, blood vessels, ligaments and tendons. Injury to these structures may delay your recovery.
What are the 2 bones in your forearm called?
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.
