Abstract

The present disclosure describes various embodiments of a plate and guide that enable fixation of a fractured bone while reducing damage to tissue in the vicinity of the fractured bone. The plate may be sized and dimensioned such that the plate may be slid underneath a muscle or other tissue and positioned into a proper location for providing fixation of the plate to the fractured bone without requiring cutting of the muscle or other tissue. The guide may be sized and dimensioned to interface with the plate such that the guide is place over the top of the muscle or other tissue, thereby enabling the guide to be used for providing screws or other devices (e.g., rods, K-wires, etc.) to the plate in a proper orientation to provide fixation to the fractured bone without requiring cutting of the muscle or other tissue.

Claims20

Dependent claims

A bone fixation system configured to reduce damage to tissue proximate a portion of a bone during fixation of a fracture in the bone, the bone fixation system comprising:

a fixation plate comprising a head portion, a shaft portion, and a plurality of openings configured to receive one or more fixation devices;
and
a guide comprising a distal end portion, a shaft portion, a proximal end portion, and a plurality of guide openings, wherein the guide is configured to be removably coupled to the fixation plate, and wherein the plurality of guide openings are configured to guide the one or more fixation devices into corresponding ones of the plurality of openings of the fixation plate to provide fixation of the fracture,
wherein the fixation plate is configured to permit the fixation plate to slide between a surface of the bone and the tissue such that at least a part of the head portion and a part of shaft portion of the fixation plate extend beyond the tissue, wherein the guide is removably coupled to the fixation plate at the part of the head portion and the part of the shaft portion that are configured to extend beyond the tissue, and wherein, when the guide is removably coupled to the fixation plate, the tissue is disposed in a space between the fixation plate and the distal end portion, the shaft portion, and the proximal end portion of the guide.

1 more element

A method for providing fixation of a fracture of a bone using a bone fixation system configured to reduce damage to tissue proximate a portion of the bone during the providing of the fixation, the method comprising:

sliding a fixation plate between a surface of the bone and the tissue, wherein the fixation plate comprises a head portion, a shaft portion, and a plurality of openings configured to receive one or more fixation devices, wherein at least a part of the head portion and a part of shaft portion of the fixation plate extend beyond the tissue;
removably coupling a guide to the fixation plate, wherein the guide comprises a distal end portion, a shaft portion, a proximal end portion, and a plurality of guide openings, wherein the guide is removably coupled to the fixation plate at the part of the head portion and the part of the shaft portion that extend beyond the tissue, wherein, when the guide is removably coupled to the fixation plate, the tissue is disposed in a space between the fixation plate and the distal end portion, the shaft portion, and the proximal end portion of the guide;
providing the one or more fixation devices into at least a portion of the bone, wherein each of the one or more fixation devices passes through at least one of the plurality of guide openings and at least one of the plurality of openings of the fixation plate during the providing the one or more fixation devices.
