Abstract:
1. A multi-articular modular fracture fixation device, with an adjustable modulus of rigidity, comprising: a plurality of tensioning elements, including convex elements having a flat end, a convex end, and an axially disposed through hole, and concave elements having a concave end, a flat end, and an axially disposed through hole; and a flexible connecting wire having a threaded first end and a stop member affixed on a second end, the connecting wire inserted through the through holes of the tensioning elements such that the tensioning elements are disposed between the stop member and the threaded first end, and wherein at least two of the tensioning elements may be selectively manipulated to place the through holes of the tensioning elements out of axial alignment and to bend the connecting wire, and a lock nut threadably disposed over the threaded first end of the guide wire so as to engage the most proximal tensioning element and to bring the most distal tensioning element into engagement with the stop member; wherein said flat end of said concave element and said flat end of said convex element may be approximated to form a stable non-articulating joint, and said convex end of said convex element may be approximated to said concave end of said concave element to provide an articulating joint that is swivelingly adjustable in its alignment in relation to said concave element; and wherein at least some of said tensioning elements include a semicircular groove on said flat end, such that when said flat ends of any two complementary elements having grooves are approximated a hole is formed and is suitable for through insertion of a pin.
