An orthopedic bone transport system includes an external fixation frame and a cable pulling device. The external fixation frame is attachable to a fixed bone segment with the external fixation frame oriented in a first plane. The cable pulling device includes a main body configured to be secured to the external fixation frame, a reel, and a transmission. The reel is rotatable about said main body and configured to wind up a cable to be secured to a transport bone segment to move said transport bone segment towards said fixed bone segment. The main body is secured to the external fixation frame with an axis of rotation of the reel oriented substantially parallel to the first plane, the axis of rotation of the reel thereby substantially lying on a transverse plane with respect to the fixed bone segment. The transmission drives the reel in order to wind up the cable.

Orthopedic cable bone transport device and bone transport system comprising said device

An orthopedic spring hinge and associated external fixation systems for the treatment of anatomical joint dysfunctions, and more particularly, to a spring hinge comprising a first base member, a second base member, a flexible first spring having a first longitudinal axis extending from the first base member to the second base member, and a flexible second spring spaced apart from the first spring and having a second longitudinal axis extending from the first base member to the second base member. The spring hinge is configured to have a maximum bending resistance in a first plane extending between the first spring and the second spring and a minimum bending resistance in a second plane orthogonal to the first plane.
