髋关节前外侧入路WatsonJones切口Word文档下载推荐.docx

1、在牵开器帮助和充分的软组织松解的情况下，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，可以提供显露股骨头和股骨颈，但是如果用DHS固定股骨颈骨折，则需要一个独立的外侧切口。2、皮肤切口Start the slightly anteriorly curved skin incision about 7-10 cm proximal of the lateral part of the greater trochanter （directed towards the tubercu

2、le 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.在股骨大转子上约7-10cm外侧略前方处行轻微弯曲皮肤切口（方向从髂结节到阔筋膜张肌起始部），向远端延伸至股骨干（大粗隆下10cm处）。3、显露阔筋膜张肌Expose the fascia lata sharply. Incise the fascia lata over

3、 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侧边界锐性分离。4、深层分离With the greater trochanter and the gluteus medius muscle exposed, retract the tensor fascia lata anteriorly and the gluteus medius muscle posteriorly. E

4、xpose the interval between the gluteus medius and the tensor fascia lata and extend it proximally over the 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。钝性分离臀中肌与阔筋膜张肌之间间隙向近端延伸至髋关节

5、。注意此间隙的血管术，可以结扎或电凝止血。5、显露髋关节囊Place a Hohmann retractor into the bone proximal 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

6、关节囊。6、松解股外侧肌The origin of the vastus lateralis 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

7、关节囊，向下牵拉肌肉。视需要调整拉钩，清除关节周围的脂肪。7、打开关节囊Make an T-shaped incision in the capsule, 关节囊做一个T型切口8、打开关节囊and place two retraction sutures, anteriorly and posteriorly. Protect the acetabular labrum.This capsulotomy shows the anterior femoral head and neck. Lateral traction and repositioning of the leg can impr

8、ove 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，以保护髋臼。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DHS来固定股骨颈骨折。9、闭合伤口Perform a meticulous debridement of all

9、 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 incision with interrupted sutures. Close the subcutaneous tissue and skin as desired.闭合伤口前仔细清除所有软组织。清除坏死组织并冲洗整个伤口以减少关节周围骨化形成，如果必要可以下负压吸引装置。间断缝合阔筋膜，缝合皮肤及皮下组织。欢迎您的下载，资料仅供参考！致力为企业和个人提供合同协议，策划案计划书，学习资料等等打造全网一站式需求
