Abstract
Various implant systems and methods of implantation are disclosed herein. The systems and methods allow a surgeon to accurately determine a suitable fastener trajectory for attaching certain components of the implant system to bone. In this manner, an appropriate fastener trajectory can be selected and used during a surgical procedure to ensure better purchase and attachment of the various components of the implant system to the bone.
Claims10
An implant system comprising:
- a tool having a shaft and a first projection;
- a baseplate having a post and a first fastener aperture;
- and
- an augment having a first opening configured to lockingly receive the post, wherein the first projection of the tool is insertable into the first fastener aperture of the baseplate and, when the first projection of the tool is inserted into the first fastener aperture, the first projection acts as a guide that directs the post of the baseplate into the first opening of the augment along a pre-defined trajectory, wherein the augment further comprises a second opening that is aligned with the first fastener aperture of the baseplate when the post of the baseplate is inserted into the first opening of the augment.

- a tool having a shaft and a first projection;
- a baseplate having a post and a first fastener aperture;
- an augment having a first opening configured to lockingly receive the post, wherein the first projection of the tool is insertable into the first fastener aperture of the baseplate and, when the first projection of the tool is inserted into the first fastener aperture, the first projection acts as a guide that directs the post of the baseplate into the first opening of the augment along a pre-defined trajectory;
- and
- an alignment guide having a first projection that defines a first bore, wherein the first projection of the alignment guide is insertable into the first fastener aperture of the baseplate.
2 more elements
An implant system comprising:
- a tool having a shaft and a first projection, wherein the tool further comprises a plurality of rotatable projections that are rotatable about a longitudinal axis of the tool, and a plurality of fixed projections that are fixed about the longitudinal axis;
- a baseplate having a post and a first fastener aperture;
- and
- an augment having a first opening configured to lockingly receive the post, wherein the first projection of the tool is insertable into the first fastener aperture of the baseplate and, when the first projection of the tool is inserted into the first fastener aperture, the first projection acts as a guide that directs the post of the baseplate into the first opening of the augment along a pre-defined trajectory, wherein the augment further comprises a plurality of first apertures configured to receive the plurality of fixed projections, and a plurality of elongate slots configured to receive the plurality of rotatable projections, and wherein each of the plurality of rotatable projections is movable laterally within an associated one of the plurality of elongate slots.
