In one embodiment, the proximal extender 640 may also include a top opening 646 and one or more neck openings 638. The top opening 646 may serve to reduce the size, weight, and surface area of the fixation feature 634 that covers a part of the long bone. Furthermore, the top opening 646 can be configured to provide structural support and rigidity to the fixation feature 634. The size and shape of the top opening 646 can vary in different embodiments of the proximal extender 640. In one embodiment, the top opening 646 can include an opening 648 between the fastener openings 618 of a fixation feature 634. The opening 648 may facilitate more flexibility in the positioning of parts of a fixation feature 634 during deployment.
