Posterior elbow pain is a pain in the back of the elbow. It may develop gradually over time (chronic), or occur suddenly from a direct impact or fall (acute). Here we explain the common causes of pain on the outside of the elbow.
Chronic pain at the back of the elbow
The following injuries are common causes of gradual onset or chronic elbow pain. You will not have noticed a precise incident or time when your injury occurred.
Elbow Bursitis – Student’s Elbow
Elbow bursitis, also known as Student’s elbow or Olecranon bursitis, is the inflammation and swelling of the bursa at the back of the elbow.
- Traumatic or repetitive impacts to this area can cause a large swelling at the back of the joint.
- Symptoms include pain in the elbow both at rest and during exercise.
- Painful swelling on the back of the elbow may limit movement.

The triceps tendon at the back of the upper arm inserts into the elbow. Injury can occur to the tendon from overuse, or from a sudden impact such as a fall. Symptoms include:
- Pain at the back of the elbow, both at rest and during exercise.
- The elbow will be tender to touch pressing in just above the bony protrusion on the back of the elbow.
- The patient may have limited mobility and straightening the elbow against resistance will be painful.

Acute posterior elbow pain
The following injuries are common causes of acute or sudden onset pain at the back of the elbow.
The olecranon is the large bony prominence at the back of the elbow on the ulna forearm bone. It is usually fractured from a direct impact or fall onto a bent elbow.
