Abstract

A trochanter attachment device can include a plate for attachment to an inner portion of a greater trochanter of a femur, a collar for attaching the plate to a hip implant, and a fastener for securing the collar to a hip implant. The trochanter attachment device can include a groove or other feature for receiving a reinforcing material, such as a wire or a cable, such as to reinforce an attachment of the device to the greater trochanter and/or the hip implant. The trochanter attachment device can include an insert attachable to the plate and configured to attach the plate to the greater trochanter. All or a portion of the plate and/or the insert can include a porous material, such as to promote bone ingrowth of the greater trochanter.
