US Patent 10413425 Hybrid prosthesis installation systems and methods

A system and method for inserting and aligning an acetabular cup in the human pelvic bone, including selectively combining aspects of a vibratory BMD3 and an axially-impacting BMD4, including initially utilizing BMD3 vibratory insertion to partially insert and perfectly align the acetabular cup into the pelvis, and subsequently switching to a BMD4 controlled impaction technique to apply specific quantifiable forces for full seating and insertion, wherein the proven advantages of the vibratory insertion prototype with the advantages of the controlled impaction prototype are combined in a single device.
