目的 探讨老年人胸腰椎椎弓根螺钉内固定术后螺钉松动的原因及预防措施. 方法 对2011年5月至2013年5月在我院行胸腰椎椎弓根螺钉内固定手术≥60岁老年患者187例临床资料进行回顾性分析,按是否发生螺钉松动分为松动组和固定良好组,观察并比较两组患者手术时间、出血量、术后6个月及末次随访视觉模拟疼痛评分(VAS)及Oswestry功能障碍指数(ODI)评分,分析螺钉松动的原因. 结果 本组行胸腰椎椎弓根螺钉内固定手术主要病因为胸腰椎侧后凸畸形、骨折、滑脱、肿瘤及退行性疾病等,术后平均随访(35.2±8.7)个月.发生内固定松动13例(7.0%),男性5例,女性8例,平均年龄(78.4±3.5)岁.发现螺钉松动时间为术后3~12个月,平均(7.6±3.7)个月.13例患者中,螺钉松动单节段1例,双节段3例,3个或3个以上节段9例.螺钉松动患者中骨质疏松10例.VAS及ODI评分,术后6个月及末次随访与术前比较,差异均有统计学意义(P<0.05);末次随访与术后6个月比较,差异无统计学意义(P>0.05).松动组性别及术前骨质疏松患病率与固定良好组比较,差异有统计学意义(P<0.05). 结论 骨质疏松是影响老年患者胸腰椎椎弓根螺钉内固定术后螺钉松动的原因之一,长节段螺钉松动概率增高,可能与老年患者脊柱力学改变有关.对于老年骨质疏松患者,是否需要骨水泥强化治疗,仍需进一步随机对照研究.
目的 探討老年人胸腰椎椎弓根螺釘內固定術後螺釘鬆動的原因及預防措施. 方法 對2011年5月至2013年5月在我院行胸腰椎椎弓根螺釘內固定手術≥60歲老年患者187例臨床資料進行迴顧性分析,按是否髮生螺釘鬆動分為鬆動組和固定良好組,觀察併比較兩組患者手術時間、齣血量、術後6箇月及末次隨訪視覺模擬疼痛評分(VAS)及Oswestry功能障礙指數(ODI)評分,分析螺釘鬆動的原因. 結果 本組行胸腰椎椎弓根螺釘內固定手術主要病因為胸腰椎側後凸畸形、骨摺、滑脫、腫瘤及退行性疾病等,術後平均隨訪(35.2±8.7)箇月.髮生內固定鬆動13例(7.0%),男性5例,女性8例,平均年齡(78.4±3.5)歲.髮現螺釘鬆動時間為術後3~12箇月,平均(7.6±3.7)箇月.13例患者中,螺釘鬆動單節段1例,雙節段3例,3箇或3箇以上節段9例.螺釘鬆動患者中骨質疏鬆10例.VAS及ODI評分,術後6箇月及末次隨訪與術前比較,差異均有統計學意義(P<0.05);末次隨訪與術後6箇月比較,差異無統計學意義(P>0.05).鬆動組性彆及術前骨質疏鬆患病率與固定良好組比較,差異有統計學意義(P<0.05). 結論 骨質疏鬆是影響老年患者胸腰椎椎弓根螺釘內固定術後螺釘鬆動的原因之一,長節段螺釘鬆動概率增高,可能與老年患者脊柱力學改變有關.對于老年骨質疏鬆患者,是否需要骨水泥彊化治療,仍需進一步隨機對照研究.

Objective To explore what cause the screw loosening after the internal fixation with thoracic and lumbar pedicle screws in the elderly and to develop the preventive measures.Methods Retrospective analysis were used to collect the clinical data from patients ager 60 years and over who had undergone surgeries of thoracolumbar pedicle screw internal fixation in our hospital during May 2011 and May 2013.Totally 187 cases were included in this study.According to whether there was a loosening of the screws, patients were divided into fixtion-loose and-well groups.The operation time and blood loss volume in the two groups were recorded.Visual analogue scale (VAS), Oswestry disability index (ODI), the rate of screw loosening were compared at 6 months after operation and the last follow-up.The causes of screw loosening were analyzed.Results The main causes for the thoracic and lumbar pedicle screw internal fixation were thoracolumbar kyphoscoliosis, fractures,spondylolisthesis, cancer and degenerative diseases, etc.Patients were followed up for an average of (35.2±8.7) months.13 patients (7.0%) were found screw loosening, 5 males and 8 females, with the mean age of (78.4 ± 3.5) years.The screw loosening occurred 3 months to 1 year after the surgery, (7.6±3.7) months on average.Among the 13 patients with screw loosening, 1 patient suffered screw loosening in single segment, 3 patients in two segments, and 9 patients in three segments or above.Osteoporosis combined with screw loosening.appeared in 10 patients VAS and ODI scores in all subjects had statistically differences at 6 months after operation and the last follow up versus preoperation (P<0.05 for all), but no statistical difference versus the last follow-up(P> 0.05).There were significant differences in gender and preoperative osteoporosis rate between the two groups (P<0.05 for both).Conclusions Osteoporosis is one of the reasons for the screw loosening in elderly patients after pedicle screw internal fixation.The increased probability of the screw loosening in long segment may be related with the change of the older spine mechanics.Further randomized controlled trials are still required to confirm whether elderly osteoporosis patients need to receive bone cement augmentation treatment.
