Abstract

An orthopaedic device for securing between first and second regions of bone separated by a growth plate, the orthopaedic device comprising: a first portion to secure to a first fixing location on the first bone region; a second portion to secure to a second fixing location on the second bone region, the first fixing location and the second fixing location being laterally offset relative to a longitudinal axis of the bone; wherein the first and second portions are pivotally coupled between a first coupling location on the first portion and a second coupling location on the second portion such that movement of the first and second portions away from each other in a direction parallel to the longitudinal axis of the bone causes relative rotation of the first bone region and the second bone region thereby reducing the lateral offset of the first location and the second location.
