目的探讨骨水泥强化椎弓根钉内固定治疗陈旧性骨质疏松性胸腰椎压缩骨折并后凸畸形的疗效。方法自2006-06—2013-08采用骨水泥强化椎弓根钉内固定治疗陈旧性胸腰椎骨质疏松性椎体压缩骨折并后凸畸形30例。观察术后后凸Cobb角、疼痛视觉模拟评分(VAS)的改善程度。结果本组手术时间115~178 min,平均145 min;术中出血量660~1 240 ml,平均810 ml。30例均获得随访7~48个月,平均21.5个月。植骨骨性愈合,后凸矫正角度无明显丢失,固定相邻节段无明显椎间不稳征象。末次随访胸腰段后凸Cobb角、VAS评分较术前明显改善。结论骨水泥强化椎弓根钉内固定治疗陈旧性骨质疏松性胸腰椎压缩骨折并后凸畸形既增强了椎弓根钉的固定强度,又矫正了脊柱后凸畸形。
Objective To investigate the curative effect of cement-enhanced pedicle screw internal fixation for the treatment of old osteoporotic thoracolumbar vertebral compression fracture and kyphosis deformity. Methods From Aug 2006 to Aug 2013, 30 cases of old thoracolumbar osteoporotic vertebral compression fracture and kyphosis were treated with pedicle screw internal fixation. The degree of postoperative kyphosis Cobb angle and pain visual analogue scale (VAS) were observed. Results The operation time of this group was 115-178 min with an average of 145 min. The intraoperative blood loss was 660-1 240 ml, with an average of 810 ml. All 30 patients were followed up for 7 ~ 48 months with an average of 21.5 months. Bone heal, no obvious loss of kyphosis correction, no obvious intervertebral instability in adjacent segments. The final follow-up thoracolumbar kyphosis Cobb angle, VAS score was significantly improved compared with preoperative. CONCLUSION: The treatment of old osteoporotic thoracolumbar vertebral compression fractures with bone cement enhanced pedicle screw fixation and kyphosis can not only enhance the fixation strength of pedicle screw, but also correct the kyphosis.
