Bone compression device

A bone compression device with a longitudinal axis, comprising:

• a primary body extending along the longitudinal axis, having an inner bore with a primary internal diameter, and a primary bone fixation pin assembly extending at an angle to the longitudinal axis,
• a secondary body extending along the longitudinal axis, having an outer diameter smaller than the primary internal diameter, and a secondary bone fixation pin assembly extending at an angle to the longitudinal axis,
• wherein the secondary body is positioned in the inner bore and moveable therethrough with respect to the primary body over an adjustment range,
• wherein the primary body comprises a guide pin positioned perpendicular to the longitudinal axis, and the secondary body comprises a guide slot comprising an aperture having an inner guide surface, the guide pin extending through the guide slot and in contact with the inner guide surface during operation, and
• an adjustment assembly connected to the primary body and secondary body for mutual adjustment thereof along the longitudinal axis,
• wherein the adjustment assembly comprises an adjustment head having a first screw thread, and the secondary body comprises an adjustment bore having a second screw thread for engagement with the first screw thread, and
• wherein the adjustment assembly further comprises a rotatable locking assembly in threaded co-operation with both the adjustment head and the adjustment bore of the secondary body to lock the mutual position of the primary body and secondary body when a required length of the bone compression device in situ is achieved;
• wherein the primary bone fixation pin assembly is arranged between the secondary bone fixation pin assembly and the adjustment head.
