摘要 目的探讨使用AO空心加压螺钉经皮固定治疗股骨颈骨折的临床效果。方法对40例股骨颈骨折的患者采用C形臂X线机透视下,牵引床+手法复位股骨颈骨折后,经皮穿带螺纹骨针3~4枚预固定,选用股骨颈轴线上3枚适合带螺纹骨针作为空心螺钉导针,引导旋入直径7.3mm的3枚加压螺纹钉治疗。结果 40例患者中骨折完全复位者26例(65.0%),骨折移位在3mm以内及骨小梁成角<15°者11例,>3mm移位者3例。所有患者术后15d拆线,未发生深静脉血栓。全部病例均获1.5~2年的随访,患髋关节功能完全正常者26例(65.0%);患髋关节活动正常、轻微疼痛,能正常工作者13例(32.5%);能扶拐自立生活,功能明显受限、股骨颈坏死者1例(2.5%)。X线及CT检查结果:骨折线消失,骨小梁连续性重建39例(97.5%);骨折线清晰、增亮,骨折断端吸收,股骨头移位,股骨头坏死1例(2.5%)。结论 AO空心加压螺纹钉经皮固定股骨颈骨折,方法简单、固定可靠、治疗效果好,适合治疗各型股骨颈骨折。
