Developmental dysplasia of the hip is a special condition that faces newborn babies, it may happen due to genetic factors or during delivery. Pavlik harness was the solution, however , it caused suffering to babies due to the presence of straps that are very uncomfortable and cause pain and itching. Our aim is to develop a new smart hip abduction device which allows the physician's in charge of the baby to control automatically and accurately the degree of opening of the device, and to evaluate the performance of the smart device statistically. The automatic control was achieved by a touchscreen which controls the servomotors and the degree of treatment. Simulation results showed the compact design which could reduce the pain of the baby and help him/her recover with less suffering. Experimental results showcased the compact design of the Smart Hip Abduction Splint providing a comfortable and flexible movement of the baby. The device User Interface and touchscreen results showed that it allows the physician to set the angle of treatment accurately in less than a second and in a feasible way. Also, valuable instructions and information were provided on the devices' screen. Statistical evaluation showed that our smart abduction hip device surpasses the pavlik harness in its performance. Our Smart HAS provided 98% of accuracy in treatment, 89% safety and 100% automatic control. For further improvement, various sensors that ensure the maximum safety and monitor the baby's treatment could be considered.
