<p>An orthopedic apparatus for selectively distracting or compressing contiguous longitudinal bone segments comprising a first and second support member each of which can be placed longitudinally coextensively adjacent respective bone segments. A first longitudinal bore extends within the first support member for receiving and threadably engaging one portion of a threaded driving rod, and a second longitudinal bore, axially aligned with the first longitudinal bore, extends within the second support member for receiving and threadably engaging another portion of the threaded driving rod. Upon rotation of the threaded driving rod the first and second support members are longitudinally simultaneously adjusted. The apparatus can be inserted into the limb according to standard orthopedic surgical procedures and then mounted adjacent the bone segments after which the support members are periodically adjusted to stimulate the growth of new bone matter between the distracted bone segments. A method for distracting longitudinal bone segments by insertably mounting an adjustable distracting apparatus adjacent longitudinal bone segments and periodically adjusting the apparatus to stimulate a build up of new bone growth between the bone segments.</p> |
