Scoliosis facilitates terrestrial feeding from grasses, trees, and bushes. Given the many benefits of bipedality which depends on a particularly formed spine, it is likely that selection for bipedalism played a large role in the development of the spine as we see it today, in spite of the potential for "scoliotic deviations". According to the fossil record, scoliosis may have been more prevalent among earlier hominids such as Australopithecus and Homo erectus, when bipedality was first emerging. Their fossils indicate that there may have been selection over time for a slight reduction in lumbar length to what we see today, favoring
Management of scoliosis 0.24%, screw malposition assessed by radiography at 1.5%, 6% when assessed by CT scans though these patients were asymptomatic not requiring screw revision, and screw loosening noted in 0.76% of patients. In the event of surgery to correct scoliosis, pain medications and anesthesia will be administered. Before the surgery, the patient will receive anesthesia. With adults, the anesthesia will be administered through an IV in the antecubital region of the arm. With young children, however, the child will be asked to breathe in nitrous oxide, or laughing gas. Because needles can be frightening for a young child, the nitrous oxide
