Patent ID: 8425519

Claim:
A device for treating fractures of a bone, comprising: a plurality of arms, each extending from a proximal end to a distal end and movable in a three-dimensional space, the proximal end of each arm being coupled to a frame; a plurality of couplings, each of the couplings being coupled to a distal end of a corresponding one of the arms, the coupling lockingly receiving a bone fixation element secured to a corresponding bone fragment such that each of the arms is coupled to a corresponding fragment of the bone; a mechanical unit supplying motion to the arms to move each of the arms relative to the frame; a controller receiving data corresponding to a desired final position of the bone fragments relative to one another and controlling the mechanical unit to move the arms relative to one another to achieve the desired final position of the bone fragments relative to one another; and a frame including a longitudinal element to which the plurality of arms is coupled, the longitudinal element being configured to rotate in order to rotate the plurality of arms relative to the frame.
