Clinical Results of Internal Fixation Using Several Instruments in Unstable Thoracolumbar Bursting Fracture

ABSTRACT

Fifty six patients with unstable thoracolumbar bursting fractures were treated using variable internal fixation devices such as the Kaneda Anterior Fixation System(Kaneda device), the Z-Plate-ATL(TM) Anterior Fixation System(Z-Plate ATL(TM) device), the Harrington device, Cotrel-Ducousset(CD) or Compact Contrel Dubousset(CCD) device or Steffee Transpedicular System with or without decompression. Such internal fixation devices were grouped into anterior and posterior internal fixation devices and compared with each other in the aspect of the degree of neurological improvement, the changes of the vertebral height and the kyphotic angle, the duration of admission, and postoperative complications. In conclusion, the anterior internal fixation device appears to be of more benefit in the management of patients with unstable thoracolumbar bursting fracture.
