In addition to providing a less invasive procedure for limb lengthening, the device has been recognized for significantly reducing the potential for complications, such as infections, during the healing process. Presently, the device is used for lengthening the femur and tibia bones. Dr. Rosenfeld has been named a “Physician of Excellence” from the Orange County Medical Association multiple years running.
