ABSTRACT
BACKGROUND:
Because of
osteoporosis, short-segment transpedicular fixation or screw-rod system fixation is prone to screw loosening depending on its poor anti-pul-out strength in
patients with thoracolumbar fracture with
ankylosing spondylitis.
OBJECTIVE:
To probe the clinic outcomes of multi-segment transpedicle spinal fixation for thoracolumbar fractures with
ankylosing spondylitis.
METHODS:
Eleven
patients with
ankylosing spondylitis combined with thoracolumbar fracture in the Fourth Department of
Orthopedics, Meizhou
Hospital,
Sun Yat-sen
University,
China from January 2009 to December 2012 were selected. Al the
patients underwent posterior reduction and multi-segment transpedicle spinal fixation, among whom, six cases were subjected to internal fixation through the pedicle of fractured
vertebra. RESULTS AND
CONCLUSION:
Al of the 11
patients were fol owed up for 13 to 36 months. Solid
bone healing was achieved in al of the
patients, and there were no
complications related to the internal fixation systems such as loosening or breakage. Three cases of
spinal cord injury achieved Frankel’s class E from class C recovery. Lumbodorsal
pain rate achieved 100%according to the
Japanese Orthopaedic
Association scoring. Results confirmed that it is effective to treat thoracolumbar fractures with
ankylosing spondylitis by posterior reduction and multi-segment transpedicle spinal fixation. Strong internal fixation and fracture union can be achieved by operation.
