Abstract:

BACKGROUND: Because of osteoporosis, short-segment transpedicular fixation or screw-rod system fixation is prone to screw loosening depending on its poor anti-pull-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. All 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: All of the 11 patients were followed up for 13 to 36 months. Solid bone healing was achieved in all 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.
