Radio-ulnar synostosis, bilateral is a rare congenital condition in which the radius and ulna bones of the forearm fuse together. This fusion can cause the forearm to be bent or twisted, and can limit the range of motion of the elbow and wrist. It can also cause the hand to be held in a claw-like position. Treatment typically involves surgery to separate the fused bones and restore normal movement.

The symptoms of radio-ulnar synostosis, bilateral include:

-Pain and Stiffness in the elbow joint
-Limited range of motion in the elbow joint
-Decreased strength in the forearm muscles
-Abnormal curvature of the forearm
-Deformity of the elbow joint
-Swelling and tenderness in the elbow joint
-Abnormal positioning of the forearm bones
-Abnormal positioning of the wrist bones
-Abnormal positioning of the hand bones

1. Trauma: Radio-ulnar synostosis can be caused by trauma to the elbow joint, such as a fracture or dislocation.

2. Congenital: Radio-ulnar synostosis can be caused by a congenital defect, such as a malformation of the elbow joint.

3. Infection: Radio-ulnar synostosis can be caused by an infection in the elbow joint, such as septic arthritis.

4. Inflammatory conditions: Radio-ulnar synostosis can be caused by inflammatory conditions, such as rheumatoid arthritis.

5. Metabolic disorders: Radio-ulnar synostosis can be caused by metabolic disorders, such as osteoporosis.

1. Surgery: Surgery is the most common treatment for radio-ulnar synostosis, bilateral. The goal of surgery is to separate the fused bones and restore normal movement of the forearm. This is typically done through an open procedure, where the surgeon makes an incision in the skin and then separates the fused bones.

2. Physical Therapy: After surgery, physical therapy is often recommended to help restore strength and range of motion in the affected arm. Physical therapy may include exercises to improve flexibility, strength, and coordination.

3. Splinting: Splinting may be used to help maintain the position of the arm and prevent further fusion of the bones.

4. Medication: Non-steroidal anti-inflammatory drugs (NSAIDs) may be prescribed to help reduce pain and inflammation.

Radio-ulnar synostosis, bilateral is a rare condition that is usually treated with surgery. The goal of the surgery is to separate the fused bones and restore normal movement of the elbow. Depending on the severity of the condition, the surgery may involve cutting the bones and inserting a metal plate and screws to hold them in place. After surgery, physical therapy may be recommended to help restore range of motion and strength. Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to help reduce pain and inflammation.
