Posterior Subluxation and Dislocation of Ulnohumeral Joint: Causes, Symptoms, and Treatment

Posterior subluxation and dislocation of the ulnohumeral joint is a rare but serious injury that occurs when the ulna and humerus bones in the elbow joint become misaligned. This can cause pain, swelling, and limited range of motion in the affected arm. If left untreated, this condition can cause long-term damage to the joint and surrounding tissues.

Causes

Posterior subluxation and dislocation of the ulnohumeral joint can be caused by a number of different factors, including:

1. Direct trauma to the elbow joint, such as a fall or blow to the arm.
2. Repetitive stress on the joint, such as from throwing a baseball or playing tennis.
3. Degenerative changes in the joint due to age or arthritis.

Symptoms

The symptoms of posterior subluxation and dislocation of the ulnohumeral joint can vary depending on the severity of the injury, but may include:

• Pain and swelling in the elbow joint.
• Difficulty moving the affected arm.
• A popping or clicking sensation in the joint.
• Numbness or tingling in the hand or fingers.
• Weakness in the affected arm.

Treatment

Treatment for posterior subluxation and dislocation of the ulnohumeral joint typically involves a combination of rest, physical therapy, and in some cases, surgery. In the early stages of the injury, the affected arm may need to be immobilized in a cast or brace to allow the joint to heal.

Physical therapy can help to strengthen the muscles surrounding the joint and improve range of motion. In some cases, surgery may be necessary to realign the bones in the joint and repair any damaged tissues.

If you suspect that you have suffered a posterior subluxation or dislocation of the ulnohumeral joint, it is important to seek medical attention right away. With proper treatment, most people are able to fully recover from this injury and regain full use of their affected arm.
