Humero-ulnar synostosis, bilateral is a rare congenital condition in which the humerus and ulna bones of the forearm are fused together. This fusion can cause the forearm to be bent or curved, and can limit the range of motion of the elbow joint. 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 range of motion.

The symptoms of Humero-ulnar synostosis, bilateral include:

-Limited range of motion in the elbow joint
-Pain and Stiffness in the elbow joint
-Decreased strength in the elbow joint
-Abnormal elbow shape
-Abnormal elbow position
-Decreased grip strength
-Decreased range of motion in the forearm
-Abnormal forearm shape
-Abnormal forearm position
-Decreased range of motion in the wrist joint
-Abnormal wrist shape
-Abnormal wrist position
-Decreased grip strength in the hand

1. Congenital: Humero-ulnar synostosis, bilateral can be caused by a genetic mutation or abnormality present at birth.

2. Trauma: Traumatic injuries to the elbow joint can cause the bones to fuse together.

3. Infection: Infections such as osteomyelitis can cause the bones to fuse together.

4. Radiation: Radiation therapy to the elbow joint can cause the bones to fuse together.

5. Tumors: Tumors in the elbow joint can cause the bones to fuse together.

1. Surgery: Surgery is the most common treatment for humero-ulnar synostosis, bilateral. The goal of surgery is to restore the normal anatomy of the elbow joint and to improve range of motion. The procedure involves cutting the fused bones and inserting a metal plate and screws to hold the bones in place.

2. Physical Therapy: Physical therapy is an important part of the treatment for humero-ulnar synostosis, bilateral. Physical therapy can help to improve range of motion, strength, and function of the elbow joint.

3. Splinting: Splinting can be used to help maintain the position of the elbow joint and to prevent further deformity.

4. Occupational Therapy: Occupational therapy can help to improve the function of the affected arm and to teach the patient how to perform daily activities with the

1. Genetic predisposition
2. Previous trauma to the elbow
3. Prolonged immobilization of the elbow
4. Congenital abnormalities
5. Infection
6. Inflammatory conditions
7. Radiation therapy
8. Neuromuscular disorders

At this time, there is no known cure for humero-ulnar synostosis, bilateral. Treatment typically involves surgical intervention to correct the deformity and restore range of motion. Medications may be prescribed to manage pain and inflammation. Physical therapy may also be recommended to help improve range of motion and strength.
