Madelung deformity is a congenital deformity affecting the forearm bone and this results in a bowed appearance of the upper extremity.
The only treatment available is surgery to correct the deformity. This usually involves cutting the deformed bone and re-shaping it to correct the deformity. Bone grafts are frequently required and metal implants such as plates, screws and wires will be used to secure the bone in its new position until the bone ends unite.
