Apparatus and methods for securing a bone implant
First Claim
1. A bone implant defining a longitudinal axis and comprising:
- an orthopedic mesh of expandable cells, the orthopedic mesh being operationally expandable, away from the longitudinal axis, inside a bone, the expandable cells including distal cells, each distal cell supporting a stem that extends away from the distal cell toward a hub, each stem supporting a tab that extends transverse to the stem, the hub defining enclosures, each enclosure;
retaining a corresponding one of the tabs;
providing clearance for the corresponding tab to rotate inside the enclosure; and
defining a clearance notch that allows a corresponding one of the stems an angular range of motion with respect to the longitudinal axis.

Abstract
Apparatus and methods for securing a bone implant are provided. The implant may be an expandable implant. The implant may be a non-expandable implant. The implant may be for repairing a bone fracture. The implant may be secured to a bone by anchors. The implant may include anchor receiving features. The anchor receiving features may be configured to direct an anchor into cortical bone. The anchor receiving features may be configured to receive an anchor driven through cortical bone. The implant may include bone engaging members configured to engage cancellous bone. An implant may include different profiles. The different profiles may be configured to secure the implant. The profiles may be configured to support the bone. The implant may have different flexing properties configured to position the implant in the bone. The implant may be positioned to receive an anchor driven through an outside of the bone.

15. A bone implant comprising:
-
an expandable orthopedic web; a plurality of stems that extend from a distal end of the expandable orthopedic web; a plurality of circumferential members, each circumferential member extending transversely from a corresponding one of the stems; and a hub that defines a plurality of enclosures, each enclosure; retaining a corresponding one of the circumferential members and providing clearance for rotation of the retained circumferential member when the expandable orthopedic web expands; and comprising a notch that provides clearance for a stem that supports the retained circumferential member and not for the retained circumferential member itself. - View Dependent Claims (16, 17, 18, 19, 20, 21)
