多节段椎体增强后椎弓根钉内固定系统在骨质疏松性椎体骨折治疗中的应用

目的探讨多节段椎体增强后应用椎弓根钉内固定系统治疗骨质疏松性椎体骨折的疗效。方法自2004年起应用骨水泥强化椎体后椎弓根钉内固定系统治疗骨质疏松性椎体骨折12例,观察后凸Cobb角矫正度、内固定稳定情况及临床症状改善程度。结果12例患者获随访6~24个月,平均13个月,椎弓根钉内固定系统无松动、脱落、折断。后凸畸形Cobb角平均矫正24.2°,疼痛VAS评分由术前平均8.7分降至术后平均2.5分,ODI评分(%)由术前平均71.5改善至术后平均32.5。结论应用椎体增强后椎弓根钉内固定系统治疗骨质疏松性椎体骨折可获得满意的临床疗效。

The application of using pedicle screw fixation with long segmental after vertebral augmentation in the treatment of osteoporotic spine fracture

Objective To explore the clinical effect of using pedicle screw fixation with long segmental after vertebral augmentation for the treatment of osteoporotic spine fracture.Methods Since December 2004,12 patients of osteoporotic spine fracture were treated by pedicle screw fixation with long segmental after vertebral augmentation.The clinical effect was evaluated by observing the changing of the Cobbs angle,the stability of spine column,the improvement of the pain and neurological symptom.Results A follow-up was performed for 6-24 months(mean 13 months).The cobb angle with kyphotic deformity had an average correction of 24.2 degrees postoperatively.There was no internal fixation failure.Oswestry score improved from 71.5 of preoperatively to 32.5 postoperatively.Pain score by VAS reduced from average 8.7 preoperatively to 2.5 postoperatively.Conclusion Satisfactory clinical results can be achieved by using pedicle screw fixation with long segmental after vertebral augmentation in the treatment of osteoporotic spine fracture.
