Summary
BACKGROUND: The most typical web site of fractures in sufferers with ankylosing spondylitis (AS) is the cervical backbone, particularly the decrease cervical backbone and cervicothoracic junction. The optimum therapy for cervical backbone fractures secondary to AS is controversial. This examine aimed to discover the consequences of posterior pedicle screw fixation alone on fractures of the decrease cervical backbone in sufferers with AS.
METHODS: From January 2006 to January 2013, a complete of 35 sufferers with AS and a decrease cervical backbone fracture had been handled utilizing solely posterior cervical/thoracic pedicle screw fixation. On this retrospective examine, we reviewed the sufferers’ charts to evaluate their case histories, operations, neurological outcomes, and issues. We additionally evaluated their postoperative radiographs to find out the time of bone fusion.
RESULTS: Altogether, 32 (91.four%) of the 35 fractures resulted from an acute harm and three (eight.6%) from a continual harm. In 25 instances, the fracture resulted from a low-energy spinal harm and in eight instances from a high-energy harm. Posterior pedicle screw fixation was profitable in all sufferers, with radiographic fusion confirmed by computed tomography. The typical time of bone fusion was three.6 months (vary three?-?6 months). The surgical procedure improved the American Spinal Harm Affiliation grade in 15 (42.9%) sufferers. No intraoperative issues occurred. Not one of the corrections resulted in neurological decompensation. The typical postoperative correction was 18°.
CONCLUSIONS: Pedicle screw fixation and autologous bone grafting by means of a single posterior strategy to decrease cervical backbone fractures in AS sufferers might stabilize the backbone, right kyphosis, and relieve stress. It’s thus affordable to suggest this surgical technique for AS-associated fractures of the decrease cervical backbone.
