非典型股骨骨折(AFFs)是一种骨质疏松症长期应用抗骨吸收治疗引起的严重并发症。规范诊疗骨质疏松症患者的AFFs,必须搞清AFFs的高危因素、诊断标准和相关治疗策略。
本文将对以上相关问题进行列表总结,以期为临床提供清晰、可操作的诊疗方案。
1. 骨质疏松症患者AFF的高危因素[1-3]
表1:

2.骨质疏松症患者AFF的诊断标准[4-5]
表2:

诊断路径关键提示:对于长期使用抗骨吸收药物(尤其是双膦酸盐或地舒单抗)的患者,若出现大腿、腹股沟或膝部慢性疼痛,应高度警惕AFF。首选双侧股骨全长X光片进行筛查;当X线结果不明确时,MRI是检测不完全骨折或早期骨膜反应最敏感的工具。
3.骨质疏松症患者不完全性AFF的治疗策略[6-7]
表3:

治疗原则总览:决策需高度个体化,综合权衡症状、功能影响、影像学风险特征及患者全身状况。双侧股骨影像检查必不可少(对侧受累率达28-40%)。同时,必须停用相关的抗骨吸收药物,并进行代谢评估与营养优化。
4.骨质疏松症患者完全性AFF的治疗策略[8-9]
表4:

治疗总原则:对于完全性AFF,髓内钉固定是金标准手术方法。成功治疗的关键在于:基于个体解剖(尤其弯曲度)选择最合适的内植物和技术,并同步启动全身性的骨骼健康管理。
