Low-profile, high tension mesh plate for subcutaneous fracture fixation

摘要

A fixation device and method for the subcutaneous fixation of bone fragments. A fixation mesh is formed by the intersection of a plurality of linear legs that are interconnected in sagittal planes to form linear sagittal lines and a plurality of crimped legs that are interconnected in transverse planes to form transverse lines. The mesh resists expansive forces that are created in the linear sagittal lines and a compressive stress is created in the transverse lines when tensile loads are applied to the linear sagittal lines resulting in a device that minimizes the gap distance between bone fragments.

1. A method of repairing a fractured patella having a plurality of bone fragments separated by fracture gaps comprising the steps of:
subcutaneously inserting a fixation mesh over a portion of the fractured patella, said mesh plate having one or more repeating segments that define a plurality of openings; said one or more repeating segments comprising a central screw hole connected to a first screw hole by a linear leg and connected to a second screw hole by a non-linear leg; and affixing said fixation mesh to the fractured patella fragments using screws so that said central screw hole and said second screw hole are positionable inwardly and outwardly with respect to each other so as to urge one or more fragments towards or away from one another.
