背景:股骨头坏死是骨科难治性疾病之一,不同分期、分型下的股骨头坏死自然塌陷病程影响着该病的进展及预后。目的:探究不同中日友好医院(China-Japan Friendship Hospital,CJFH)分型下国际骨循环研究协会(Association Research Circulat...背景:股骨头坏死是骨科难治性疾病之一,不同分期、分型下的股骨头坏死自然塌陷病程影响着该病的进展及预后。目的:探究不同中日友好医院(China-Japan Friendship Hospital,CJFH)分型下国际骨循环研究协会(Association Research Circulation Osseous,ARCO)Ⅱ期股骨头坏死未塌陷患者5年内自然塌陷病程,并分析不同CJFH分型的股骨头塌陷率及塌陷风险。方法:回顾性选取2016年10月至2017年10月在西安交通大学附属红会医院门诊确诊为ARCOⅡ期股骨头坏死未塌陷的患者为研究对象,根据是否塌陷将患髋分为塌陷组(n=82)和未塌陷组(n=70),统计不同CJFH分型的股骨头塌陷风险以及5年内塌陷时间、塌陷数量和塌陷率,并绘制不同CJFH分型股骨头的Kaplan-Meier生存曲线图。结果与结论:①共纳入患者97例,152髋,随访期间有82髋塌陷,总塌陷率为53.9%,其中M型、C型、L1型、L2型和L3型塌陷率分别为0.0%,36.7%,51.4%,72.2%和77.8%,各组间比较差异有显著性意义(P<0.05);②在塌陷风险方面,L1型塌陷风险为C型的1.704倍(P>0.05),而L2型、L3型塌陷风险分别为C型的3.866倍、6.423倍(P<0.05);③在Kaplan-Meier生存曲线方面,ARCOⅡ期患者股骨头中位生存时间为3年,95%置信区间为2.885-3.471年,第1,3,5年股骨头生存率分别为65.1%(99/152),50.7%(77/152),46.1%(70/152);④结果表明,不同CJFH分型影响着ARCOⅡ期股骨头坏死患者的塌陷率,其中L3型患者塌陷率最高,L2型和L1型患者次之,C型患者塌陷率较低,M型患者无塌陷,这表明股骨头外侧柱的保留对股骨头坏死自然塌陷病程有重要意义。展开更多
目的:探讨锁定钢板内固定治疗股骨近端外侧壁骨折块后的效果。方法:2021年1月至2022年6月收治31例合并外侧壁骨折的股骨转子间骨折患者,其中15例单纯采用股骨近端防旋髓内钉(proximal femoral nail antirotation,PFNA)固定,男3例,女12例...目的:探讨锁定钢板内固定治疗股骨近端外侧壁骨折块后的效果。方法:2021年1月至2022年6月收治31例合并外侧壁骨折的股骨转子间骨折患者,其中15例单纯采用股骨近端防旋髓内钉(proximal femoral nail antirotation,PFNA)固定,男3例,女12例;年龄(75.87±7.46)岁;另16例采用PFNA内固定后再应用预弯好的3.5 mm螺孔锁定钢板内固定外侧壁骨折,男4例,女12例;年龄(76.15±9.47)岁。术后随访观察记录比较两组手术指标、尖顶距(tip-apical distance,TAD)、术后负重站立时间、骨折复位情况。术后6个月根据Harris髋关节评分评价术后髋关节功能。结果:两组患者均获得随访,时间7~17(12±5)个月。两组术后即刻颈干角为111°~132°(119.3±8.3)°。骨折复位效果:PFNA组,优11例,可2例,差1例;PFNA+锁定钢板组,优12例,可3例,差1例。PFNA组1例发生螺旋刀片经股骨头切出。两组手术时间、术中出血量及手术切口长度比较,差异有统计学意义(P<0.05);两组TAD及术后负重站立时间比较,差异无统计学意义(P>0.05)。两组术后6个月Harris各项评分和总分比较,差异有统计学意义(P<0.05)。结论:应用PFNA辅助锁定钢板内固定合并外侧壁骨折的股骨转子间骨折疗效确切,可较好恢复外侧壁完整性,提高PFNA内固定的稳定性,术后并发症少。展开更多
