Dissections of the common digital nerve and its branches were performed in the second and third web spaces in five fresh-frozen cadaveric feet. Plantarly directed nerve tetherings, which were histologically demonstrated to be nerve branches, were consistently present along the course of each common digital nerve. These plantarly directed nerve branches were found in highest concentration in the distal aspect of the common digital nerve proximal to the bifurcation into the proper digital branches. The presence of these nerve branches may contribute to the high incidence of Morton's neuroma recurrence either due to traumatic neuroma formation in the branches or to failure of proximal retraction of the more distally resected nerve stump.
在5只新鲜冷冻尸体足的第二和第三趾蹼间隙进行了指总神经及其分支的解剖。沿每条指总神经走行始终存在向足底方向的神经束带，经组织学证实为神经分支。这些向足底方向的神经分支在指总神经分叉为固有指神经近端的远侧部分浓度最高。这些神经分支的存在可能是莫顿神经瘤复发率高的原因，要么是由于分支中形成创伤性神经瘤，要么是由于更远端切除的神经残端近端回缩失败。
