Abstract
A patella fracture fixation system includes a bone plate that is configured to be implanted along an anterior approach. The bone plate has a fixation hub and a plurality of fixation nodes that are connected to the fixation hub. The fixation hub and the fixation nodes can define respective fixation holes. The bone plate can further include legs that are configured to be bent around respective inferior aspects of the patella.
Claims17
A patella bone plate comprising:
- a fixation body including:
- a fixation hub having an inner surface configured to face a patella bone and an outer surface opposite the inner surface, and an array of fixation holes that extend through the fixation hub from the inner surface to the outer surface;
- and
- a plurality of fixation nodes that extend from the fixation hub, each of the plurality of fixation nodes defining a respective fixation hole;
- and
- at least one leg that extends out from the body, the at least one leg being deformable and having a length sufficient so as to wrap around an inferior rim of the patella bone, the at least one leg including at least one fixation hole,
- wherein the at least one leg comprises a medial leg and a lateral leg that extend out from respective eyelets that define adjacent ones of the fixation nodes of the fixation body, and
- wherein the at least one leg comprises an inferior leg that extends out from the fixation hub at a location between the respective eyelets.
5 more elements
A patella bone plate comprising:
- a fixation body including:
- a fixation hub having an inner surface configured to face a patella bone and an outer surface opposite the inner surface, a first array of fixation holes that extend through the fixation hub from the inner surface to the outer surface, and a second array of fixation holes that is disposed radially outward with respect to the first array, wherein adjacent fixation holes of the fixation holes of the second array are spaced equidistantly from each other;
- and
- a plurality of fixation nodes that extend from the fixation hub, each of the plurality of fixation nodes defining a respective fixation hole,
- wherein the fixation body defines a plurality of apertures that extend through the fixation hub from the outer surface to the inner surface, wherein the apertures are elongate along a central axis.
