Abstract
The present invention is generally directed to intramedullary nails that can include a keel configured for rotational stabilization and/or a multi-sectioned rod configured to apply compression to a fracture.
Claims20
A method of installing an intramedullary nail comprising:
- cutting a groove in a medullary canal of a bone;
- providing an intramedullary nail, the nail comprising:
- a rod comprising a proximal portion and a distal portion;
- and
- at least one elongate keel disposed longitudinally on an outer surface of the rod,
- wherein at least a portion of the keel is received within the groove such that the groove is capable of serving as a track for the keel to guide the intramedullary nail in the intramedullary canal;
- and
- deploying the intramedullary nail such that the intramedullary nail mechanically expands or retracts axially when the intramedullary nail is positioned in the medullary canal.

A method of installing an intramedullary nail comprising:
- cutting a groove in a medullary canal of a bone;
- providing an intramedullary nail, the nail comprising:
- a rod comprising a proximal portion, a distal portion, and an outer surface;
- a deployment mechanism;
- and
- a deployable keel oriented longitudinally along the rod;
- inserting the intramedullary nail into an intramedullary canal with the keel in a retracted position;
- and
- actuating the deployment mechanism to non-rotatably deploy the deployable keel from a retracted position to a deployed position such that the deployable keel is received at least in part in the groove.
6 more elements
A method of installing an intramedullary nail comprising:
- providing an intramedullary nail comprising:
- a rod comprising a proximal portion and a distal portion and configured to transition from an expanded configuration to a compressed configuration;
- a compression mechanism configured to move the proximal and distal portions axially with respect to one another from the expanded configuration to the compressed configuration;
- and
- a radial expansion mechanism wherein the intramedullary nail is expandable or contractible in a radial direction resulting in a change in a volume of the intramedullary nail,
- inserting the intramedullary nail into a medullary canal;
- actuating at least one of the compression mechanism or the radial mechanism such that either the axial length or the radial width of the intramedullary nail changes.
