摘要：
A method and apparatus for surgical correction of malformations of digits of a foot. Part of the joint is removed to expose bone ends. The bone ends are spaced apart from each other at a distance greater than would be suitable for knitting of said bone ends to each other with bone tissue. Holes are bored in each of the bone ends. An implant, including shafts and a central spacer, is inserted into each of the holes in the bones. This implant consists entirely of absorbable material. The implant is left permanently in place to be completely absorbed as it is replaced by fibrous scar tissue. This tissue forms an effective joint replacement.
