Abstract
A bone plate according to an exemplary aspect of the present disclosure includes, inter alia, a body portion. The body portion includes a first slotted portion extending at least partially through the body portion and a plurality of teeth adjacent the first slotted portion for engaging a driver in the first slotted portion. The body portion also includes a second slotted portion extending at least partially through the body portion and a ramped portion at least partially surrounding the second slotted portion. The ramped portion tapers from an outer surface of the body portion toward an inner surface of the body portion.
Claims19
A bone plate comprising:
- a body portion;
- a first slotted portion extending at least partially through the body portion;
- a plurality of teeth adjacent the first slotted portion for engaging a driver in the first slotted portion;
- a second slotted portion extending at least partially through the body portion, wherein the first slotted portion and the second slotted portion are connected by a transition opening such that the first slotted portion and the second slotted portion form one continuous slot;
- and
- a ramped portion at least partially surrounding the second slotted portion, the ramped portion tapering from an outer surface of the body portion toward an inner surface of the body portion.
A bone plate assembly comprising:
- a bone plate including a body portion;
- a driver;
- a first slotted portion extending at least partially through the body portion;
- a first plurality of teeth adjacent a first side of the first slotted portion for engaging the driver in the first slotted portion;
- and
- a second plurality of teeth adjacent a second side of the first slotted portion for engaging the driver in the first slotted portion, wherein the first plurality of teeth include a first coarseness and the second plurality of teeth include a second coarseness different from the first coarseness, and wherein the second plurality of teeth engage a locking portion of the driver.
A bone plate comprising:
- a body portion including a first end and a second end, wherein the first end includes at least one fastener opening for attaching the body portion to a first bone segment;
- a first slotted portion extending at least partially through the body portion;
- a plurality of teeth adjacent the first slotted portion for engaging a driver in the first slotted portion, wherein the plurality of teeth are located on a first side of the first slotted portion and a second plurality of teeth are located on a second side of the first slotted portion;
- a second slotted portion extending at least partially through the body portion, wherein the second slotted portion is configured to align with a second bone segment separate from the first bone segment;
- and
- a ramped portion at least partially surrounding the second slotted portion, the ramped portion tapering from an outer surface of the body portion toward an inner surface of the body portion;
- wherein the plurality of teeth include a first coarseness having a first density of teeth per unit length and the second plurality of teeth include a second coarseness having a second density of teeth per the unit of length different, wherein the second coarseness is different from the first coarseness, and wherein the second plurality of teeth engage a locking portion of the driver.
