措施说明
大体时间
有愈合放射学证据的参与者百分比
大体时间:长达 12 个月的随机化

股骨颈骨折愈合和愈合并发症的迹象包括射线照片上骨折线的消失。 如果参与者在 12 个月的访问中有愈合的放射学证据,则认为该参与者有愈合的放射学证据。

百分比计算如下:(具有愈合的放射学证据的参与者人数/分析的参与者总数)* 100。

长达 12 个月的随机化
行走时疼痛得到控制的参与者百分比
大体时间:长达 12 个月
最严重的疼痛数字评定量表 (NRS) 用于评估疼痛对参与者生活的影响。 NRS 第 3 项评估了步行测试期间最严重的肌肉骨骼疼痛严重程度。 疼痛由 11 点李克特量表测量。 以下分界点用于对 NRS 反应进行分类:0 = 无疼痛,1 至 4 = 轻度疼痛,5 至 6 = 中度疼痛,7 至 10 = 剧烈疼痛。 分数越高表明疼痛越严重。 NRS 评分 <7 且 NRS 评分较基线没有恶化 >2 的参与者被归类为没有严重的骨折部位疼痛。 百分比计算如下:(行走期间疼痛控制的参与者人数/分析的参与者总数)* 100。
长达 12 个月
就诊前 24 小时内无严重骨折部位疼痛的参与者百分比
大体时间:长达 12 个月
NRS 用于评估疼痛对参与者生活的影响。 就诊前 24 小时内评估骨折部位疼痛的严重程度。 疼痛由 11 点李克特量表测量。 就诊前 24 小时内 NRS 评分 <7 且 NRS 评分较基线没有恶化 >2 的参与者被归类为没有严重的骨折部位疼痛。 百分比计算如下:(就诊前 24 小时内疼痛控制的参与者人数 / 分析的参与者总数)* 100。
长达 12 个月
负重期间无严重骨折部位疼痛的参与者百分比
大体时间:长达 12 个月
最严重的疼痛 NRS 用于评估疼痛对参与者生活的影响。 骨折部位疼痛的严重程度是根据负重时的疼痛来评估的。 疼痛由 11 点李克特量表测量。 负重期间 NRS 评分 <7 且 NRS 评分较基线没有恶化 >2 的参与者被归类为没有严重的骨折部位疼痛。 百分比计算如下:(负重期间疼痛控制的参与者人数 / 参与者总数)* 100。

具有康复功能证据的参与者百分比
大体时间:长达 12 个月

功能性康复被定义为能够以 ≥ 0.05 米/秒 (m/s) 的步态速度行走,且相对于基线的变化 ≥ -0.1 m/s。 步行测试涉及让参与者以自选的舒适步伐步行 7 米 (m) 的距离。 测试的 4 米部分被计时以确定参与者的步态速度(以 m/s 为单位)。

百分比计算如下:(具有愈合功能证据的参与者人数/分析的参与者总数)* 100。

长达 12 个月
能够走动的参与者百分比
大体时间:长达 12 个月
走动的能力被定义为在有或没有康复辅助的情况下可以走动。 百分比计算如下:(能够走动的参与者数量/分析的参与者总数)* 100。

恢复骨折前门诊状态的参与者百分比
大体时间:长达 12 个月
骨折前的行走状态被定义为行走时有或没有助行器。 如果参与者的术后行走状态恢复到或比术前行走状态有所改善,则认为参与者已恢复骨折前行走状态。 百分比计算为 =(恢复门诊状态的参与者人数 / 分析的参与者总数)*100。
长达 12 个月
最严重骨折部位疼痛从基线到 6 个月的平均变化
大体时间:基线,6 个月
最严重的疼痛 NRS 用于评估疼痛对参与者生活的影响。 NRS 评分 <7 的参与者被归类为没有严重的骨折部位疼痛。 使用针对基线、治疗组、区域、骨折类型和固定类型调整的协方差分析 (ANCOVA) 计算最小二乘法 (LS) 平均值。
基线,6 个月
步态速度从基线到 6 个月的平均变化
大体时间:基线,6 个月

大体时间:基线,最长 6 个月
WOMAC:是一份自我报告的问卷,包含 24 个问题,涵盖 3 个健康领域:疼痛(5 个项目:行走时、使用楼梯、床上、坐着或躺着以及站立时)、僵硬(2 个项目:第一次醒来后和后来在白天)和身体机能。 通过对各个项目求和并将分数转换为 0 到 100(最好到最差)的等级来对每个领域进行评分。 较低的分数表示更好的健康状况或功能。 使用针对基线、治疗组、区域、骨折类型、固定类型、就诊和就诊-治疗交互作用进行调整的 ANCOVA 计算 LS 平均值。
基线,最长 6 个月
欧洲生活质量问卷 (EQ-5D) 总体健康评分从基线到 6 个月的平均变化
大体时间:基线,6 个月
EQ-5D 是一个 5 项、自我报告、通用、多维、与健康相关的生活质量工具,有 5 个项目。 总体健康状态评分也使用视觉模拟量表 (VAS) 自我报告,评分范围从 0(可想象的最差健康状态)到 100(可想象的最佳健康状态)。 较高的分数代表较好的健康状态,0 代表可想象的最差健康状态,100 代表可想象的最佳健康状态。 使用针对基线、治疗组、区域调整的ANCOVA计算LS均值。
