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
目的探讨股骨近端防旋髓内钉(proximal femoral nail antirotation,PFNA)-Ⅱ联合外侧支撑钢板内固定重建治疗外侧壁不稳定型股骨转子间骨折的临床疗效。方法回顾性分析2012年1月至2016年12月于我院通过切开复位、应用PFNA-Ⅱ联合外侧支...目的探讨股骨近端防旋髓内钉(proximal femoral nail antirotation,PFNA)-Ⅱ联合外侧支撑钢板内固定重建治疗外侧壁不稳定型股骨转子间骨折的临床疗效。方法回顾性分析2012年1月至2016年12月于我院通过切开复位、应用PFNA-Ⅱ联合外侧支撑钢板治疗外侧壁不稳定型股骨转子间骨折病人21例,其中男13例,女8例,年龄为31~82岁,平均(56.0±2.3)岁。通过术后随访复查资料评估骨折复位质量及愈合情况,骨折愈合后的髋关节Harris评分(hip Harris score,HHS)用以评价病人的关节功能。结果本组21例病人术后均获得了良好的复位,固定牢固。所有病人均获得随访,随访时间为3~18个月,平均(9.0±2.6)个月,所有病人均获得骨性愈合。术后HHS:优16例,良4例,可1例,优良率为95.2%(20/21)。结论通过PFNA-Ⅱ联合外侧支撑钢板是治疗外侧壁不稳定型股骨转子间骨折的有效方法,保留了股骨转子外侧壁的完整性,增强了骨折端的稳定性,具有较强的坚固性和稳定性,提高了固定疗效。展开更多
