Scoliosis are "captured", meaning that they are held fast between the ilium bones of the pelvis. Compared to humans, Old World monkeys have far larger erector spinae muscles, which are the muscles which hold the spine steady. These factors make the lumbar spine of most primates less flexible and far less likely to deviate than those of humans. While this may explicitly relate only to lumbar scolioses, it is possible that small imbalances in the lumbar spine could precipitate thoracic problems as well. Scoliosis may be a byproduct of strong selection for bipedalism. For a bipedal stance, a highly mobile, elongated
Management of scoliosis will put them to sleep so the anesthesiologist can then insert the IV in order to give them the anesthesia. After the surgery, the patient will most likely be given morphine. Until the patient is ready to take the medicine by mouth, an IV will be giving them their medication. Morphine is the most common pain medicine used after scoliosis surgery, and is often administered through a patient-controlled analgesia (PCA) system. The PCA system allows the patient to push a button when they are feeling pain, and the PCA will emit the drugs into the IV and then into the
