Abstract
An apparatus for vertical callus distraction includes a linear drive having first and anchors, each with a plate-shaped region, that are able to be displaced relative to one another by way of the linear drive and substantially orientated perpendicularly to the direction of displacement. The first anchor is connected to a fixed bone segment and the second anchor is connected to a movable bone segment for cultivating the growth of callus between the bone segments. The linear drive has a first element with the first anchor fixed to an end of the first element, and a second element with the second anchor fixed to an end of the second element. The first and second elements are translationally displaced relative to one another with the linear drive preventing rotation of the first element relative to the second element, and preventing relative rotation between the first and second anchors.
