Abstract
An extramedullary compression and fixation apparatus consists of a pre-curved, malleable band having a first end and a second end, and at least one bone engaging structure protruding from the band toward an interior space defined by the band. The band is configured to be compressed (e.g., crimped) over a bone fracture site to conform the curvature of the band to a curvature of a surface of bone around the bone fracture site. The at least one bone engaging structure is configured to dig into the outer cortex of the bone when the band is compressed. The band is configured to maintain compression of the bone across the bone fracture upon the band being compressed without additional external fixation devices.
Claims16
An extramedullary compression and fixation apparatus consisting of:
- a pre-curved, malleable band having a first free end and a second free end, the pre-curved, malleable band extending along a portion of a helix such that the first and second free ends are circumferentially spaced by at least 180 degrees about a central longitudinal axis of the helix and the first and second free ends are longitudinally offset about the central longitudinal axis;
- and
- at least one bone engaging structure protruding from the pre-curved, malleable band toward an interior space defined by the pre-curved, malleable band,
- the pre-curved, malleable band configured to be compressed over a bone fracture site of a bone into permanent deformation of the pre-curved, malleable band to conform the curvature of the pre-curved, malleable band to a curvature of a surface of the bone around the bone fracture site, the at least one bone engaging structure configured to dig into an outer cortex of the bone when the pre-curved, malleable band is compressed over the bone fracture site, and wherein the pre-curved, malleable band is configured to maintain compression of the bone across the bone fracture site upon being compressed without external fixation devices,
- the pre-curved, malleable band including no holes specifically adapted for receiving screws.

A method of bone fracture reduction comprising:
- a) applying one or more trial compression and fixation apparatus to an exterior of a fractured bone so that the trial compression and fixation apparatus extends across a fracture plane to determine which one trial compression and fixation apparatus is a best fit for the fractured bone across the fracture plane;
- b) selecting an implantable extramedullary compression and fixation apparatus corresponding to the trial compression and fixation apparatus determined to be the best fit, the extramedullary compression and fixation apparatus having a first free end and a second free end, the pre-curved, deformable band extending along a portion of a helix such that the first and second free ends are circumferentially spaced by at least 180 degrees about a central longitudinal axis of the helix and the first and second free ends are longitudinally offset about the central longitudinal axis;
- and
- c) compressing the selected implantable extramedullary compression and fixation apparatus into permanent deformation onto the bone over and across the fracture plane.
