Elbow Fusion in Children: Treatment Options and Concerns - Orthopedics

Share to:

The right hand cannot be fully extended?


Dear Dr.
Wang,
My son is currently 1 year and 1 month old.
Previously, we noticed that he is unable to fully extend his right arm and cannot perform rotational movements.
When he was six months old, he had an X-ray that revealed the two bones in his right forearm are fused at the elbow, meaning the upper ends of the two bones are joined together and not separated.
At that time, the doctor suggested we observe the situation, hoping he might naturally become left-handed, which would not be a problem.
However, we have now discovered that he is right-handed.
Given this condition, he is unable to use a spoon to eat by himself and will likely struggle to hold a pencil in the future, which could impact his daily life.

I would like to ask the doctor if surgery could resolve this issue, or if my child is too young and requires a further observation period.
I would also like to know how common such symptoms are.
Thank you for your hard work!
Sincerely,
A mother concerned about her child's future.

Dr. Wang Shouji reply Orthopedics


Your child's issue is radial-ulnar synostosis, which is often unilateral and sporadic, with a minority being related to genetics.
Due to the mobility of the hand, shoulder, and elbow, most functional limitations can be compensated for.
Therefore, not many patients undergo surgery; only those with significant forearm deformities may consider surgical intervention.
It is recommended to visit an orthopedic or rehabilitation clinic for a detailed examination and treatment.
Lastly, I wish your child a speedy recovery.

Dear Concerned Parent,
Thank you for reaching out with your concerns about your son's condition. It’s understandable to feel anxious about his ability to use his right arm effectively, especially given the implications for his future development and daily activities.
From what you’ve described, it seems your son has a condition known as "elbow fusion" or "congenital elbow dislocation," where the two bones in the forearm (the radius and ulna) are fused at the elbow joint. This can significantly limit the range of motion and functionality of the arm, affecting tasks such as eating with utensils or writing.


Treatment Options
1. Observation: In some cases, especially in very young children, doctors may recommend a period of observation. This is because children's bones and joints can sometimes develop and change as they grow. However, given that your son is now 1 year and 1 month old and has not shown improvement, it may be time to consider more active interventions.

2. Surgical Intervention: Surgery could be a viable option to address the fusion. The goal of surgery would be to separate the fused bones and restore normal function to the elbow joint. This procedure is typically performed by a pediatric orthopedic surgeon who specializes in such conditions. The timing of the surgery can be crucial; while some surgeons may prefer to wait until the child is older to ensure better outcomes, others may recommend early intervention to maximize function.

3. Physical Therapy: Post-surgery, physical therapy would likely be necessary to help your son regain strength and range of motion in his arm. This would involve exercises tailored to his specific needs and may include both passive and active movements.


Concerns and Considerations
- Age and Development: At 1 year old, your son is still in a critical period of development. While surgery can provide a solution, it’s essential to weigh the risks and benefits. Younger children may have better healing potential, but the complexity of the surgery and the recovery process must be considered.

- Commonality of the Condition: Congenital elbow fusion is relatively rare, but it can occur. Early diagnosis and intervention are crucial in managing the condition effectively.
- Long-term Outcomes: If surgery is performed successfully, many children can regain significant function in their arms. However, the extent of recovery can vary based on the specific nature of the fusion and the timing of the intervention.
- Future Activities: With successful treatment, your son should be able to engage in typical childhood activities, including using utensils and writing. However, the degree of success can depend on various factors, including the surgical technique used and adherence to rehabilitation protocols.


Next Steps
I recommend scheduling a consultation with a pediatric orthopedic specialist who has experience with elbow conditions. They can provide a thorough evaluation and discuss the potential for surgical intervention. It’s also beneficial to gather as much information as possible about the procedure, recovery time, and expected outcomes to make an informed decision.

In the meantime, continue to support your son’s development in other areas, and consider engaging him in activities that do not require the use of his right arm, allowing him to explore and learn in ways that accommodate his current abilities.

I hope this information helps clarify your concerns and provides a pathway forward for your son’s treatment. Please feel free to reach out with any further questions or for additional support.

Wishing you and your son all the best,
