JOT:电磁导航置入股骨逆行髓内钉的近端交锁螺钉

2014-08-14 林超文 丁香园

髓内钉固定是股骨干骨折治疗的金标准。当患者合并有双侧股骨骨折、同侧髋关节或胫骨骨折、肥胖或怀孕时,临床医生更倾向于选择逆行髓内钉治疗股骨干骨折。但是由于大腿软组织较多,特别是肥胖患者,想要准确置入近端交锁螺钉非常困难。这无疑会增加手术时间,还对骨科医生非常具有挑战性。虽然术中 C 臂机透视可增加螺钉定位的准确性,但是也会增加患者、手术医生和放射技师的放射暴露时间,特别是孕妇患者。目前有医疗机构开发

髓内钉固定是股骨干骨折治疗的金标准。当患者合并有双侧股骨骨折、同侧髋关节或胫骨骨折、肥胖或怀孕时,临床医生更倾向于选择逆行髓内钉治疗股骨干骨折。

但是由于大腿软组织较多,特别是肥胖患者,想要准确置入近端交锁螺钉非常困难。这无疑会增加手术时间,还对骨科医生非常具有挑战性。虽然术中 C 臂机透视可增加螺钉定位的准确性,但是也会增加患者、手术医生和放射技师的放射暴露时间,特别是孕妇患者。

目前有医疗机构开发出计算机电磁导航进行远端锁定螺钉固定的新系统(SURESHOT Distal Targeting System),研究表明电磁导航可协助手术医生在股骨顺行髓内钉固定术中更快、更准确地打入远端交锁螺钉,而且无任何辐射。

为比较透视下徒手置钉技术和电磁导航下逆行置入股骨髓内钉近端交锁螺钉的手术时间,美国的 Somerson 医生等进行了这个研究,文章最近发表在 Journal of Orthopaedics Trauma 上。

研究共采用了 6 具尸体的双侧下肢(共 12 根完整的股骨),一侧股骨在透视下使用标准的徒手置钉技术打入股骨近端 2 枚交锁螺钉,另一侧则在电磁导航下置入近端 2 枚交锁螺钉。

分别记录两组术中置入近端交锁螺钉所需要的时间以及放射暴露时间。

研究结果显示:透视下徒手置钉技术置入近端交锁螺钉的平时为 405±165.7 秒,而电磁导航下为 311±78.3 秒。另外,置入近端交锁螺钉时放射暴露平均时间为 29.5±12.8 秒。
研究表明在股骨逆行髓内钉固定术中使用电磁导航置入近端交锁螺钉能有效减少手术时间和放射暴露时间。

CORR:严重暴力股骨干骨折不增加老年患者死亡率

预计到2030年,美国60岁以上的老年人数将会翻倍,随着人口寿命的增加,老年骨折的发生率也会随着增加。到2050年,老年创伤患者将会占到医院创伤接诊病人的总数的40%,占用25%的医疗资源。由于身体机能下降、合并心脏病、慢阻肺等内科疾病,和年轻人相比,老年患者的死亡率较高。为了解高能量严重暴力导致的股骨干骨折对老年患者的影响,Kushal V. Patel等医生进行了一项对照性研究,结果发表在20
