Description of the Procedure
- External fixation device—This framed device is positioned around the leg. Pins and wires are placed through the skin and tissue to reach the bone and lengthen it. Some have a dial attached to the frame. This dial is turned to slowly lengthen the bone.
- Internal fixation device—This is placed inside the leg. It is positioned on the bone. Some of these devices have a nail with a tool that automatically lengthens the bone. In other cases, it is used with the external device.
