髋关节前外侧入路-Watson-Jones切口演示教学

1、此文档来源于网络,如有侵权请联系网站删除1、术前预备 The anterolateral approach Watson-Jones to the proximal femur, through the interval between glutei and tensor fascia lata provides somewhat limited access to the hip joint along with the lateral proximal femur. With well-positioned retractors and adequate soft-tissue relea

2、ses, it is possible to perform open reduction of displaced femoral neck fractures 31-B, and some femoral head fractures 31-C. A more medial approach to the hip joint Iliofemoral or Smith-Peterson, medial to the tensor fascia lata, may improve access to the femoral head and neck, but for fixation of

3、the neck with a sliding hip screw, a separate lateral incision will be required. 前外侧入路即 W-J 入路显露股骨近端,通过臀肌与阔筋膜张肌之间有限显露髋关节及股骨近端； 在牵开器帮忙和充分的软组织松解的情形下,可以用来复位股骨颈骨折（ 31-b ）,有时也可以复位些股骨头骨折（31-C ）；一个更靠内侧显露髋关节的切口如 Iliofemoral 切口或 S-P 切口,在阔筋膜张肌内侧,可以供应显露股骨头和股骨颈,但是假如用 DHS 固定股骨颈骨折, 就需要一个独立的外侧切口；2 、皮肤切口 Start the

4、slightly anteriorly curved skin incision about 7-10 cm proximal of the lateral part of the greater trochanter directed towards the tubercule of the iliac crest the posterior landmark of tensor fascia lata origin. Distally, the incision extends along the femur about 10 cm below the greater trochanter

5、. 在股骨大转子上约7-10cm 外侧略前方处行稍微弯曲皮肤切口（方向从髂结节到阔筋膜张肌起始部）,向远端延长至股骨干（大粗隆下只供学习沟通用10cm 处）；此文档来源于网络,如有侵权请联系网站删除3、显露阔筋膜张肌Expose the fascia lata sharply. Incise the fascia lata over the femur and extend this incision proximally along the posterior border of the tensor fascia lata.锐性显露阔筋膜张肌；在股骨处切开阔筋膜张肌并向近端沿着阔筋膜张肌后

6、侧边界锐性分别；只供学习沟通用此文档来源于网络,如有侵权请联系网站删除4、深层分别With the greater trochanter and the gluteus medius muscle exposed, retract the tensor fascia lata anteriorly and the gluteus medius muscle posteriorly. Expose the interval between the gluteus medius and the tensor fascia lata and extend it proximally over the

7、 hip joint. This can be best done by blunt dissection.Be aware of vessels running across this interval. They require ligation or cautery.显露大粗隆及臀中肌, 将阔筋膜张肌向前方牵开, 臀中肌向后方牵开； 钝性分别臀中肌与阔筋膜张肌之间间隙向近端延长至髋关节；结扎或电凝止血；只供学习沟通用留意此间隙的血管术, 可以此文档来源于网络,如有侵权请联系网站删除5、显露髋关节囊 Place a Hohmann retractor into the bone proxi

8、mal to the hip capsule. Additional retractors anteriorly and posteriorly will open the dissected interval. External rotation of the leg improves access to the hip capsule. 在髋关节股骨头部放置Hohmann 拉钩,另外在前和后方各放置一个拉钩,可以显露解剖间隙；外旋大腿将有助于显露髋关节囊；只供学习沟通用此文档来源于网络,如有侵权请联系网站删除6、松解股外侧肌 The origin of the vastus lateral

9、is muscle should be released from the anterior inferior trochanteric region to expose the underlying hip capsule. Retract the muscle inferiorly. Adjust the retractors as necessary, and debride periarticular fat to expose the hip capsule. 从大转子前下方剥离股外侧肌起点显露潜在的关节囊,向下牵拉肌肉；视需要调整拉钩,清除关节四周的脂肪；只供学习沟通用此文档来源于

Protect the acetabular labrum. This capsulotomy shows the anterior femoral head and neck. Lateral traction and repositioning of

11、the leg can improve visualization. The incison can be prolonged distally over the proximal vastus lateralis to allow insertion of screws or DHS for femoral neck fracture fixation. 在关节囊前方和后方置入两根缝合线,以爱护髋臼；此关节囊切开术可以显露股骨头和颈前面,外侧牵开或旋转大腿可以增加显露；此切口可以沿股外侧肌延长,以便拧入股骨颈螺钉或只供学习沟通用DHS 来固定股骨颈骨折；此文档来源于网络,如有侵权请联系网站删除9、闭合伤口Perform a meticulous debridement of all soft tissues before starting wound closure. Remove necrotic tissue and irrigate the entire wound to decrease the risk of periarticular ossification. Insert suction drains if desired.Close the fascia lata inci
