1. A method of compressing and realigning animal bone structures and passing a drill pin therethrough to retain said structures in a desired alignment, as applied to the correction of splay foot deformity in the human foot, comprising the steps of aligning two adjustable members on opposite sides of said bone structures of said human foot, one of said members being aligned on the medial side of the first metatarsal shank and the other of said members being aligned on the lateral side of the fifth metatarsal head, moving said members inwardly toward and in axial alignment with one another, thereby compressing and realigning said bone structures, clamping said members in relatively immovable positions, inserting a threaded drill pin through an axial passage in one of said members, advancing said drill pin by rotation thereof through said passage toward the other of said members and in axial alignment therewith through said fifth metatarsal head, under the fourth, third and second metatarsal shafts successively, and into said first metatarsal shank, thereby causing said drill pin to pierce and traverse said bone structures, stopping the advance of said drill pin when the end thereof has penetrated the interior of the most remote therefrom of the bone structures, and severing said drill pin at its point of entry into said fifth metatarsal head, the closest thereto of the bone structures, whereby a portion of said drill pin interconnects said most remote and closest bone structures to hold them in a desired relatively compressed alignment.
