"如果你的跟腱撕裂,医生可能会建议进行外科手术修复跟腱。 跟腱是一层很厚的组织,它连接着小腿后部的两块肌肉——比目鱼肌和腓肠肌,以及脚后跟的跟骨。它是人体最大、最强壮的肌腱。它可以让脚趾向下发力。这个动作对于蹬地行走、跳跃、奔跑或踮起脚尖都是必要的。 跟腱是人体最常见的易损伤肌腱之一。突然、有力的上下脚部动作会撕裂或破裂跟腱。这是一种常见的成人运动,包括跑步、跳跃和和突然改变方向的运动,如打篮球、踢足球、打网球。跟腱撕裂的其他危险因素有:年龄增长、服用某些抗生素、向跟腱注射类固醇、性别为男性、体重指数升高、吸烟、周围血管疾病和糖尿病。 跟腱断裂可以是部分的,也可以是全部断裂。部分撕裂意味着肌腱仍然相连。完全撕裂是指肌腱撕裂成两半。 重新连接跟腱两端的外科手术可以采用三种方式之一:开放式,小切口式,或经皮。 在开放式修复过程中,医生会在小腿后部做一个切口。将皮肤切开,这样医生就能看到撕裂的肌腱。医生会用针把这两头缝在一起。偶尔也会用到腓肠肌上的一些组织。这些组织会被折叠起来并缝合在肌腱上,使其更强壮。有时会用捐赠者的组织来代替。用缝线或缝合钉缝合切口。 在小切口手术中,会在断裂的跟腱上开一个较小的切口。将皮肤打开,露出撕裂的肌腱末端。将一个特殊的手术器械插入该区域。这个器械上有几个小洞,可以准确地告诉医生缝针的位置。缝线将通过每个孔进入皮肤和肌腱。移除器械,它将把缝线拉到皮肤下,这样就只剩下肌腱与缝线相连。然后从另一端开始,重复这些步骤。医生将每侧的顶部和底部缝合在一起,重新连接肌腱。用缝线或缝合钉缝合切口。 在经皮手术过程中,医生会做更小的手术切口。可能要切3~6刀,但这取决于医生的操作。缝线将穿过每个洞和撕裂肌腱的每一端。缝线会被拉在一起,重新连接肌腱。切口将用缝线缝合。"
