Nanjing University Medical SchoolMinimally invasive surgery for THA(MIS-THA)代表性的为微创直接前入路，微创前外侧入路，微创后侧入路及后外侧入路，以及双切口入路。前外侧（OCM）入路和前侧入路及双切口均不损伤肌肉，为真正意义的微创切口。前侧入路和双切口的应用很少，报道至今但目前仍很少医院采用。OCM目前在德国应用很广，国内少数医院应用。Bone&Joint Center,The Affiliated Drum Tower Hospital of Nanjing University Medical SchoolBone&Joint Center,The Affiliated Drum Tower Hospital of Nanjing University Medical School前侧入路 前外侧入路及后侧入路解剖Bone&Joint Center,The Affiliated Drum Tower Hospital of Nanjing University Medical SchoolBone&Joint Center,The Affiliated Drum Tower Hospital of Nanjing University Medical School前侧入路是一个改良的Smith-Peterson入路。以股骨大转子为界(2/3在上方,1/3 在下方),平行于髂前上棘与腓骨头的连线后方2 cm 为切口方向,切口长度限于5 10 cm。不伤肌肉，且在神经肌肉界面进行，缺点：股骨操作困难。Bone&Joint Center,The Affiliated Drum Tower Hospital of Nanjing University Medical SchoolBone&Joint Center,The Affiliated Drum Tower Hospital of Nanjing University Medical School后侧微创小切口后侧切口是一个改良Gibson切口。患者侧卧位,骨盆固定,以大转子后侧顶点为中心,自后上向前下,做一长约8 10 cm 的切口。缺点：伤臀肌及外旋肌肉，并非真正意义微创，后脱位风险高。Bone&Joint Center,The Affiliated Drum Tower Hospital of Nanjing University Medical SchoolBone&Joint Center,The Affiliated Drum Tower Hospital of Nanjing University Medical School两切口入路two-incision approachBerger于2004年首先报道了两切口入路法,这种手术方式需要一定的特制手术工具。第一个切口是长约5 cm 的前外侧切口,用来切除股骨头和安放髋臼假体;第二个切口是后路切口,用来进行股骨准备,切口位置与股骨髓内钉的切口类似。该手术方式不需切断臀中肌和臀后外旋肌,手术从肌肉间隙进入,组织损伤小，能保留关节囊，是真正意义上的微创THA 手术。缺点：麻烦，常需要透视。Bone&Joint Center,The Affiliated Drum Tower Hospital of Nanjing
