A hip and pelvic splint system is designed to immobilize both the pelvic region and lower extremities of a patient suffering from a hip or pelvic fracture. This allows ready transport of the patient with little or no pain or additional injury caused by shifting of the hip or pelvis. The device consists of a foam leg insert that is first placed between the legs of a patient to help stabilize the patient's lower extremities. A flexible splint component is then slid beneath the patient's lets and hips. The splint component is then closed over the patient and tightened with straps. The lower edge of splint component is secured snuggly about the legs in the vicinity of the patient's knees so that the foam leg insert can immobilize the legs. The upper edge of the splint is secured snuggly about the upper abdomen, thereby immobilizing the pelvis. Hand holds on the device allow paramedics to lift the patient without distorting the fracture.
