One or more additional screw segments may be utilized to assist in limb lengthening. The traction force serves to separate a distal bone segment from a proximal bone segment at a specified, controllable rate, allowing new bone growth to fill in the resulting gap. Components of the apparatus provide support and alignment to the residual bone during both the lengthening and consolidation phases. External components of the apparatus may be removed after desired limb length has been achieved, reducing the risk of infection and improving patient mobility. | 12-04-2014 |
