Early Onset Scoliosis (EOS) occurs in children under 10 years of age and many cases have a higher probability of progression during growth. The EOS has been treated with growing rod" procedure to avoid interference with spinal growth. Patients have to undergo a series of operations to have the rod lengthened for maintaining the correction without affecting the growth of the spine. Adjusting the rods requiring major surgery, costly, and is associated with negative psychosocial outcomes. In an attempt to solve these problems, we have developed a new smart medical device namely, Smart Growing Rod Device (SGRD), that proposes treating EOS with less invasive procedures to minimize the complications associated with the current techniques as well as reducing cost and improving treatment control. This innovative device will have an internal control system, allowing the growing rod to be adjusted based on neural network estimated monthly growth value and a pressure sensor, which determines when the optimum length has been reached. This is accomplished without X rays or other scanning. This study investigates the proposed SGRD for the treatment of EOS via testing our prototype smart growing device with scoliosis model and also with a spine finite element model. The results of those models are very promising and demonstrate system function and effectiveness for treatment of EOS. This will improve quality of life for scoliosis patients, and is more cost-effective than is the traditional growing rod procedure."
