Implant to stress bone to alter morphology

摘要

An implant operable to alter morphology of a long bone can comprise a first longitudinal member, a second longitudinal member, and an adjusting member. The first longitudinal member can have a bone attachment end and a first connecting end. The second longitudinal member can have a second bone attachment end and a second connecting end. The adjusting member can connect to both of the first and second connecting ends. The adjusting member can be selectively moveable from a first implanted position where the first and second connecting ends are fixed to respective ends of the long bone and spaced apart a first distance to a second implanted position where the first and second connecting ends are fixed to the respective ends of the long bone and spaced apart a second distance. The second distance is less than the first distance causing a long bone to be compressed between the first and second bone attachment ends.

主权项

1. A method of altering morphology of an unbroken long bone, the method comprising:
coupling a first bone attachment end of a longitudinal plate to a first portion of the unbroken long bone; advancing a securing member through an opening in the longitudinal plate and partially into the unbroken long bone; and continuing the advancing of the securing member into the unbroken long bone such that a portion of the securing member slidably engages the longitudinal plate causing the longitudinal plate to the in tension between the first bone attachment end and the opening while concurrently causing a portion of the unbroken long bone to be in compression to change an angle of a longitudinal axis of the unbroken long bone.
