锤状趾和爪状趾矫正(PIP关节成形术和融合)

ID: ANH18212chis
医学动画文字记录:八个脚趾的中间关节被称为近端指间关节(PIP关节)。锤状趾和爪状趾是指一个或多个脚趾处于异常弯曲的位置。如果你有锤状趾,PIP关节是弯曲的,所以脚趾看起来像锤子。如果你是爪状趾,脚和脚趾的连接处是向上弯曲的,而PIP关节是向下弯曲的。这让脚趾看起来像爪子。如果非手术治疗不起作用,医生可能会建议你进行外科手术,如PIP关节成形术和融合术,以伸直脚趾。手术开始前,医生会在脚趾顶部做一个切口。切开脚趾骨上的韧带和肌腱以暴露关节。接下来,切除两块骨的末端。这让脚趾有更多的空间放松和伸直。有时,将一根针或其他固定装置插入骨头,以保持脚趾在愈合时保持直立。手术结束后,用缝线缝合切口。医生也可能会在脚趾愈合过程中用石膏或夹板固定。随着关节愈合,将形成瘢痕组织,使两块骨接合在一起。如果使用了针,几周后将在医生诊室将其取下。要了解更多关于锤状趾或爪状趾的治疗方法,请咨询医生。
