Objective To understand the efficacy of artificial tiger bone powder on low back pain in senile primary osteoporosis,and to explore its possible mechanism.Methods A total of 76 elderly patients with low back pain due to primary osteoporosis were selected and randomly divided into treatment and control group using the random number table,with 38 cases in each group.Patients in the treatment group received oral artificial tiger bone powder.Patients in the control group received oral Calcarea Carbonica and vitamin D.Numeric rating scale (NRS) and visual analogue scale (VAS) were used to assess the pain before and 3 and 6 months after treatment.Oswestry disability index (ODI) and Japanese Orthopedic Association (JOA) scores were used to assess the lumbar function.Results There were no differences of pain and lumbar function between the two groups before the treatment.NRS,VAS,ODI,and JOA in treatment group were better than those in control group 3 and 6 months after treatment (P ＜ 0.05).Conclusion Artificial tiger bone powder can relieve low back pain caused by senile primary osteoporosis,and can improve low back function and ability of daily activities.%目的 了解人工虎骨粉治疗老年原发性骨质疏松症所引发腰背疼痛的治疗效果,并探讨其可能的机制.方法 选择原发性骨质疏松症腰背疼痛老年患者76例,采用随机信封法分为治疗组和对照组,每组各38例.治疗组另外给予人工虎骨粉口服,对照组给予碳酸钙和维生素D口服.治疗前、治疗后第3、6个月,分别运用数字疼痛评分(numeric rating scale,NRS)、视觉模拟疼痛评分(visual analogue scale,VAS)对疼痛进行评估;运用Oswestry功能障碍指数(oswestry dability index,ODI)、JOA下腰功能(Japanese Orthopaedic Association,JOA)评分对腰背功能进行评估.结果 治疗前两组患者疼痛及腰背功能无差别.治疗后第3、6个月,治疗组的NRS评分、VAS评分、ODI指数、JOA评分均优于对照组(P＜0.05).结论 人工虎骨粉能够缓解老年原发性骨质疏松症所引发的腰背疼痛,可改善患者腰背功能,提高日常活动能力.
