Posterior Instrumentation and Fusion for Unstable Fractures and Fracturehyphen;Dislocations of the Thoracic and Lumbar SpineA Comparative Study of Three Fixation Devices in 70 Patients

摘要

NA;Acute unstable thoracic and lumbar spine fractures were treated with either Harrington rods and hooks, Luque rods with sublaminar wires, or Ahyphen;O dynamic compression plates with pedicle screws. The results demonstrated failure of all three techniques to maintain the sagittal plane correction at 12 months' followhyphen;up. Furthermore, in lumbar fractures, Harrington rods did not restore or maintain sagittal plane alignment as well as Luque rods or pedicle screws and plates. Lastly, the pedicle screw fixation system required a shorter segment fusion.
