1. A bone fracture fixation system comprising:
- a bone plate configured to bear against a proximal surface of the bone, said bone plate defining a plurality of openings therethrough;
an elongated tension element sized to pass through one of said plurality of openings and through the bone from the proximal surface to a distal surface thereof;
a distal anchor attached to said tension element and configured to engage the distal surface of the bone when the tension element passes through the bone; and
a proximal anchor engageable between said bone plate and said tension element to maintain tension in said tension element between said proximal anchor and said distal anchor.

Abstract
A bone fracture fixation system comprises a bone plate configured to bear against a proximal surface of the bone and a plurality of elongated tension elements, each sized to pass through an opening in the bone plate and through the bone from the proximal surface to a distal surface thereof. Each tension element is anchored to the bone and maintained in tension by a distal anchor attached to said tension element and configured to engage the distal surface of the bone and a proximal anchor engageable between the bone plate and the tension element.

18. A method for fixation of a bone fracture comprising:
-
positioning a bone plate on a proximal surface of the bone, the bone plate including a plurality of openings therethrough;
passing at least two elongated tension elements through at least one of said plurality of openings and through the bone to a distal surface thereof;
anchoring the at least two tension elements at the distal surface;
tensioning the at least two tension elements; and
while maintaining the tension in the tension elements, anchoring the tension elements to the bone plate. - View Dependent Claims (19, 20, 21)
