Apparatus and methods for fracture repair
First Claim
1. An apparatus for treating a fracture of a bone the bone having an inner cavity, the apparatus comprising:
- a plate configured to be positioned outside the bone and define a surface outside the bone;
a first anchoring substrate configured to;
expand inside the inner cavity; and
define a central longitudinal axis that is oblique to the surface outside the bone; and
a second anchoring substrate configured to expand between the central longitudinal axis and the first anchoring substrate;
wherein;
the first anchoring substrate, in an expanded state, is configured to engage an anchor that penetrates the inner cavity;
the second anchoring substrate, in an expanded state, is configured to engage the anchor that penetrates the inner cavity; and
in operation, the plate;
supports the anchor from outside of the bone.

Abstract
Apparatus and methods for bone fracture repair. The apparatus may include a structural support for positioning a first bone segment relative to a second bone segment. The apparatus may include an anchoring substrate. The anchoring substrate may be configured to compress the first bone segment to the second bone segment. The anchoring substrate may transmit tension from a distal bone segment anchor in the first bone segment to a proximal bone segment anchor in the second bone segment. The apparatus may be configured to be deployed percutaneously in an inner cavity of a bone. The apparatus may be installed in an open fracture. The apparatus may be expanded, self-expanding or configured for mechanically actuation. Some embodiments of the apparatus may include a central axis member that may be used in conjunction with expansion of one or both of the structural support and the anchoring substrate to configure the apparatus.
