Abstract
An extracorporeal bone compressing link and apparatus and method using same. Active devices that incorporate the extracorporeal bone compressing link can transport and compress bone through external means by acting on conventional bone fasteners including but not limited bone fasteners including but not limited to screws, pins or wires that penetrate through the skin and fixate into bone.
Claims26
An extracorporeal link for connecting percutaneous bone fasteners comprising an element wherein:
- (a) the element comprises a plurality of pairs of transverse holes, wherein
- (i) the plurality of pairs of transverse holes are located about the element;
- (b) the element is configured in a first configuration, wherein, in the first configuration, each pair of transverse holes in the plurality of pairs of transverse holes comprises a first transverse hole mis-aligned with a second transverse hole;
- (c) the element is operable for being held under force in a second configuration, wherein, in the second configuration
- (i) each of the pair of transverse holes in the plurality of pairs of transverse holes comprises the first transverse hole aligned with the second transverse hole, and
- (ii) each pair of transverse holes in the plurality of pairs of transverse holes is capable of allowing a bone fastener to pass through the pair of the transverse holes in the plurality of transverse holes to secure to one or more bone segments;
- and
- (d) the element is operable to move toward the first configuration after being released from the force, wherein
- (i) for each of the pair of transverse holes in the plurality of pairs of transverse holes, the movement toward the first configuration is capable of applying moments and forces to the bone fastener passed through the first transverse hole and the second transverse hole of the pair of transverse holes by mis-aligning of the first transverse hole and the second transverse hole, and
- (ii) the moments and forces capable of being applied to the bone fastener are operable to act through the skin to transport and compress the one or more bone segments.
