PERIPROSTHETIC BONE PLATES

摘要

The present disclosure relates to bone plates that are configured for use with bones having periprosthetic fractures. For example, in the event that a proximal femur is fractured in an area that is adjacent to a prosthetic component, such as a femoral stem used in a hip replacement, the periprosthetic bone plates of the present invention may be used. In one exemplary embodiment, the periprosthetic bone plates include a periprosthetic zone having a plurality of central apertures and a plurality of outer apertures that are offset from the central apertures. The periprosthetic zone may further include a plurality of indentations, each indentation extending longitudinally between adjacent outer apertures to narrow a width of the bone plate.

主权项

1. A bone plate for use with a bone having a periprosthetic fracture, the bone plate having a longitudinal axis that extends from a first end to a second end of the bone plate, the bone plate comprising:
a bottom surface configured to face the bone; a top surface opposite the bottom surface; a first side wall and a second side wall joining the top and bottom surfaces; and a periprosthetic zone located at the first end of the bone plate, the periprosthetic zone comprising a plurality of outer apertures that extend through the bone plate from the top surface to the bottom surface, the plurality of outer apertures offset from the longitudinal axis in a direction perpendicular to the longitudinal axis, the first and second side walls undulating in the periprosthetic zone such that, along a first length of the bone plate and in a direction from the first end toward the second end of the bone plate, the first side wall narrows inwardly toward the longitudinal axis as the second side wall widens outwardly from the longitudinal axis, and along a second length of the bone plate in the direction from the first end toward the second end of the bone plate, the first side wall widens outwardly from the longitudinal axis as the second side wall narrows inwardly toward the longitudinal axis.
