Forefoot varus is a physical and radiographic examination finding associated with the Progressive Collapsing Foot Deformity (PCFD). Varus position of the forefoot relative to the hindfoot is caused by medial midfoot collapse with apex plantar angulation of the medial column. Some surgeons use the term to describe this same deformity (see Introduction section with nomenclature). Correction of this deformity is important to restore the weightbearing tripod of the foot and help resist a recurrence of foot collapse. When the forefoot varus deformity is isolated to the medial metatarsal and medial cuneiform, correction is indicated with an opening wedge medial cuneiform (Cotton) osteotomy, typically with interposition of an allograft bone wedge from 5 to 11 mm in width at the base. When the forefoot varus is global, involving varus angulation of the entire forefoot and midfoot relative to the hindfoot, other procedures are needed to adequately correct the deformity.

前足内翻是一种与进行性塌陷足畸形（PCFD）相关的物理和影像学检查结果。前足相对于后足的内翻位置是由中足内侧塌陷引起的，内侧柱的顶点跖屈角。一些外科医生使用这个术语来描述这种相同的畸形（见命名法中的介绍部分）。纠正这种畸形对于恢复足部负重三脚架并有助于防止足部塌陷复发很重要。当前足内翻畸形仅局限于内侧跖骨和内侧楔骨时，建议采用内侧楔形（科顿）切开术进行楔形切开术矫正，通常在基部用 5 到 11 毫米宽的同种异体骨楔形进行间置。当前足内翻呈全球性时，涉及整个前足和中足相对于后足的内翻角度，需要其他手术来充分纠正畸形。
