Abstract
Various embodiments of an impact absorbing pad are disclosed herein. Each pad is configured to protect a load bearing surface of an implant from damage when the implant is implanted. Each pad may have an attachment portion that allows the pad to be attached to the load bearing surface. An impactor tool may also be attached to the load bearing surface and utilized the drive a portion of the implant into a bone cavity. The pad may be removed by hand, removed with the tool, or implanted with the implant. Related systems and methods for using and making the pad are also disclosed.
Claims17
An impact absorbing pad comprising:
- a substantially planar portion including a first substantially planar surface having a first surface area defined by a perimeter and a second substantially planar surface having a second surface area substantially the same as the first surface area, the second substantially planar surface opposite the first substantially planar surface,
- wherein the perimeter corresponds with a shape of a load bearing surface of an implant and includes an exterior peripheral edge and an interior peripheral edge;
- and
- an attachment portion that is integral with the substantially planar portion and configured to removably attach the substantially planar portion to the load bearing surface of the implant, the attachment portion including one or more peripheral tabs on each of the exterior and interior peripheral edges, the peripheral tabs being integral with the substantially planar portion, wherein the one or more peripheral tabs on the interior peripheral edge is located interior to the exterior peripheral edge and in between a width of the substantially planar portion measured between opposing sides of the exterior peripheral edge,
- wherein the attachment portion is movable relative to the substantially planar portion.

- and
- a removal tab spanning between a first terminal end and a second terminal end of the perimeter of the first substantially planar surface, the perimeter being substantially U-shaped, such that the one or more peripheral tabs on the interior peripheral edge is fully enclosed by the combination of the substantially planar portion and the removal tab,
- wherein the attachment portion is movable relative to the substantially planar portion.

A prosthetic insertion system comprising:
- an implant having a load bearing surface;
- an impactor tool having a striking surface;
- and
- an impact absorbing pad having a substantially planar portion and an attachment portion that is integral with the substantially planar portion, the attachment portion configured to removably attach the substantially planar portion to the load bearing surface of the implant,

- wherein the attachment portion includes one or more peripheral tabs on each of the exterior and interior peripheral edges, the peripheral tabs being integral with the substantially planar portion, the one or more peripheral tabs on the interior peripheral edge located interior to the exterior peripheral edge and in between a width of the substantially planar portion measured between opposing sides of the exterior peripheral edge,
- wherein any impaction forces applied to the striking surface of the impactor tool are transmitted through the substantially planar portion of the impact absorbing pad to the load bearing surface of the implant when the impact absorbing pad is attached to the load bearing surface, and
- wherein the attachment portion is movable relative to the substantially planar portion.
