Abstract:
1. A spreader system comprising: a first post configured to be coupled to a first bone fixation element that is attached to a first bone part, the first post including a first post body that is elongate along a first direction and defines a proximal end and a distal end spaced from the proximal end along the first direction, the first post further including a first socket that extends into the distal end of the first post body and a first expandable member disposed within the first socket such that as the first socket receives a head of the first bone fixation element the first expandable member expands to permit the first socket to receive the head, and after the first socket has received the head the first expandable member contracts to thereby couple the first bone fixation element to the first post such that the first post is poly-axially pivotable relative to the head of the first bone fixation element; and a second post configured to be coupled to a second bone fixation element that is attached to a second bone part, wherein at least one of the first post and second post is configured to move relative to the other after the first and second posts have been coupled to the first and second bone fixation elements, respectively.
