Abstract:
[Objective]To approach the unique characteristics and the choice of surgery of low lumbar spine burst fractures.[Method]In this group 23 patients with low lumbar spine burst fractures were included.They were classified into three types : type one: single vertebral body fracture,were treated with short segmental pedicel screw system.type two:multiple vertebral body fracture,treated with long segmental pedicel screw system;type three:type one or type two combined with sacral vertebra fractures,treated with lumbar-sacral-ilio combination pedicel screw system.The intervertebral height of the fractured vertebral body and lumbar lordosis were evaluated both before and after operation on X-ray.The spinal impingement of bone was evaluated on CT scan,the neurofunction was evaluated with ASIA system and the clinical outcome were evaluated with Charles system.[Result]All patients were followed up for 1～5 years.The intervertebral height of the fractured vertebral body increased from preoperative 34%(20%～50%) to postoperative 88%(70%～95%).The lumbar lordosis angel increased from preoperative 35??7?to postoperative 38??10?.The spinal impingement of bone area decreased from preoperative 55%(35%～90%)to postoperative 6%(0%～10%).ASIA score increased by 1-3 degree,the clinical outcome reached 85% according to Charles classification.[Conclusion]Instable low lumbar spine burst fractures should be treated with surgery as early as possible,according to different fracture segment,it can be treated with short-long segmental pedicel screw system or lumbar-sacral-ilio combination pedicel screw system respectively.
