a Illustration of the dual-press mechanism, showing the proximal body, modular neck, locking bolt, and anti-rotational pin. b and c This figure depicts “exploded” and “assembled” views of the two modular femoral implant components. d This close-up photograph of the assembled implant shows that the neck and stem have no gap, converting into a monoblock construct similar to non-modular designs. e This illustration depicts some of the multiple neck options available for any stem
