A trigonometric evaluation of the amount of correction of metatarsus primus varus obtainable via lateral displacement of the first metatarsal head in a Chevron osteotomy technique revealed that approximately 1 degree of correction may be obtained for each millimeter of lateral shift. This calculated correction was correlated with the actual correction obtained in ten feet. Narrowing of the metatarsal head associated with removal of the medial eminence was an additional corrective factor.
通过人字形截骨术将第一跖骨头向外移位来矫正第一跖骨内翻的量进行三角学评估后发现，每向外移位1毫米大约可获得1度的矫正。该计算出的矫正量与在10只足部获得的实际矫正量相关。与去除内侧隆起相关的跖骨头变窄是另一个矫正因素。
