Abstract
A system for varying distance between bone segments comprises an intramedullary nail (100) and a driving shaft (210). The intramedullary nail (100) comprises a head (110) attached relative to a first bone segment (410); a housing (120) attached with the head (110); a rotational to linear motion convertor mechanism (140) having an input part and an output part (160); and a transmission (130) having an input member (131) & an output member (133), operatively coupled with input part (150) of rotational to linear motion convertor mechanism (140) and configured to transmit rotational motion and power at an angle. Further, at least a portion of the rotational to linear motion convertor mechanism (140) is contained in the housing (120) and the output part (160) is attached relative to a second bone segment (420). Additionally, the driving shaft (210) is configured to detachably connect with an input member (131) of the transmission.
