叩击式骨应力刺激仪治疗对骨质疏松性股骨转子间骨折患者血清骨钙素水平的影响

摘要

目的：探讨叩击式骨应力刺激仪治疗对骨质疏松性股骨转子间骨折患者血清骨钙素水平的影响。方法将56例骨质疏松性股骨转子间骨折患者按照随机数字表法随机分为观察组和对照组，每组28例。患者入院后均根据患者具体情况给予动力髋螺钉（DHS）或股骨近端髓内钉（PFNA）治疗。观察组在术后1周即给予叩击式骨应力刺激仪干预治疗；对照组患者术后按常规方法进行康复处理，不给予叩击式骨应力刺激治疗。比较两组临床疗效以及骨钙素水平、住院时间和骨折愈合时间等指标。结果观察组患者的优良率为85.7℅，对照组患者的优良率为57.1℅，观察组的临床疗效显著优于对照组，差异具有统计学意义（ P ﹤0.05）。术后1个月和3个月时，观察组患者血清骨钙素水平较术前显著升高（ P ﹤0.05），而对照组患者术后各时点骨钙素水平与术前比较，差异无统计学意义（ P ﹥0.05）。组间比较显示，术前两组骨钙素水平无统计学差异（ P ﹥0.05），术后1、3个月，观察组患者血清骨钙素水平均明显高于对照组患者（ P ﹤0.05）。观察组患者住院时间及骨折愈合时间均短于对照组，差异有统计学意义（ P ﹤0.05）。两组并发症发生率比较，差异无统计学意义（ P ﹥0.05）。结论叩击式骨应力刺激仪治疗能提高骨质疏松性股骨转子间骨折患者的血清骨钙素水平，促进患者的骨折愈合。%Objective To explore the effect of rap style bone stress stimulator on serum osteocalcin levels in patients with osteoporotic in-tertrochanteric fractures. Methods 56 patients with osteoporotic femoral intertrochanteric fracture in our hospital were randomly divided into ob-servation group and control group,28 cases in each group. The patients were treated with dynamic hip screw(DHS)or proximal femoral nail(PF-NA)after admission. The patients in the observation group were given rap style bone stress stimulator therapy after 1 weeks of operation. The pa-tients of control group were treated by routine method. The clinical efficacy and osteocalcin levels,length of stay and fracture healing time and oth-er indicators were compared. Results The excellent and good rate of the observation group was 85. 7℅ ,which was higher than that of the control group(57. 1℅ )( P ﹤ 0. 05). 1 months and 3 months after operation,the serum osteocalcin level of patients in the observation group increased significantly( P ﹤ 0. 05),but the osteocalcin level of the control group were not statistically significant between different time point( P ﹥ 0. 05). The levels of osteocalcin were no significant difference between two groups before operation( P ﹥ 0. 05). 1,3 months after surgery,the serum os-teocalcin levels of patients in the observation group were significantly higher than those in control group( P ﹤ 0. 05). The hospitalization time and fracture healing time of the observation group were shorter than those in the control group,the difference was statistically significant( P ﹤ 0. 05).The incidence of complications in the two groups was not statistically significant( P ﹥ 0. 05). Conclusion Percussion type bone stress stimulator can improve serum BGP level in patients with osteoporotic femoral intertrochanteric fracture,promote the healing of fracture patients.
