Management of scoliosis entering the thoracic or abdominal cavities, or more commonly, performed from the back (posterior). A combination may be used in more severe cases, though the modern pedicle screw system has largely negated the need for this. In recent years all-screw systems have become the gold-standard technique for adolescent idiopathic scoliosis. Pedicle screws achieve better fixation of the vertebral column and have better biomechanical properties than previous techniques, so enabling greater correction of the curve in all planes. Pedicle screw-only posterior spinal fusion may improve major curve correction at two years among patients with adolescent idiopathic scoliosis (AIS) as compared to
Supernumerary body part and two legs. People with this condition often wish to amputate what they see as additional body parts. A phantom limb is the sensation that a missing limb is still attached to the body. A supernumerary phantom limb is the sensation of having an extra limb or body part despite no such limb actually existing. It is an uncommon syndrome, usually due to some kind of brain injuries in the somatosensory cortex or in some parts of the right hemisphere of the brain, usually due to a stroke in the brain. A chimera is an animal or plant that has
