Abstract:
In combination with an orthopaedic external fixator having proximal and distal base members that can be manipulated relative to each other to position a first tissue segment relative to a second tissue segment, an adjustable strut comprising:a telescopic body with a proximal end and a distal end;a pair of connectors, one rotatably attaching the proximal end of the strut to the proximal base member and one rotatably attaching the distal end of the body to the distal base member, each of said connectors comprising:a) a first pivot member joined to the adjacent end of the body;b) a second pivot member pivotally joined to the first pivot member; andc) a third pivot member pivotally joined to the second pivot member and pivotally joined to the adjacent base member;wherein the first pivot member is pivotable relative to the second pivot member about a first rotational axis;wherein the second pivot member is pivotable relative to the third pivot member about a second rotational axis that is orthogonal to the first rotational axis;wherein the third pivot member is pivotable relative to the adjacent base member about a third rotational axis that is orthogonal to the second rotational axis; andwherein the first, second and third rotational axes all substantially intersect at a single coincident point of universal rotation thereby permitting the body to rotate in three dimensions relative to the adjacent base member without translating relative to the adjacent base member.
