External spinal fixation is used in cases where fusion is indicated and for reducing the number of stiffened segments in lumbar sacral pain. Owing to the percutaneous implantation, only the pedicle oval is available for localizing the screw in a-p X-rays. Cadaver studies have shown that the root of the arch and the halo are not identical and that unless one relies on the midpoint of the halo the pedicle may be perforated medially. rate, with markedly enhanced fusion of the lumbar spine following external spinal fixation.

D016267	External Fixators	External devices which hold wires or pins that are placed through one or both cortices of bone in order to hold the position of a fracture in proper alignment. These devices allow easy access to wounds, adjustment during the course of healing, and more functional use of the limbs involved.
