Abstract
Exemplary intramedullary implant systems are provided for performing surgical procedures. The intramedullary implant systems may be used for performing bone fracture, bone fusion, or osteotomy procedures within joints.
Claims23
An intramedullary implant system, comprising:
- an implant including a plate portion and an integral intramedullary portion;
- a plurality of talons provided on the integral intramedullary portion and configured to deploy from a first position to a second position to increase a rotational stability of the implant relative to a bone;
- a locking screw received through an opening of the plate portion;
- and
- a crossing screw received through an additional opening of the plate portion or the integral intramedullary portion,
- wherein the crossing screw extends at a non-perpendicular angle relative to a centerline axis of the implant,
- wherein the plate portion is laterally offset from a longitudinal centerline axis of the integral intramedullary portion such that a majority of the plate portion is shifted laterally beyond both a first lateral side edge and a second lateral side edge of the integral intramedullary portion.

An intramedullary implant system, comprising:
- an implant including a plate portion and an integral intramedullary portion;
- a plurality of retractable talons provided on the integral intramedullary portion and configured to deploy from a first position to a second position to increase a rotational stability of the implant relative to a bone;
- a first locking screw received through a first opening of the plate portion;
- a second locking screw received through a second opening of the plate portion;
- and
- a crossing screw received through a third opening of the integral intramedullary portion,
- wherein the crossing screw extends at a non-perpendicular angle relative to a centerline axis of the implant,
- wherein the plate portion is laterally offset from a longitudinal centerline axis of the integral intramedullary portion such that a majority of the plate portion is shifted laterally beyond both a first lateral side edge and a second lateral side edge of the integral intramedullary portion,
- wherein the integral intramedullary portion is configured in a shape of a nail body, and the third opening extends through the nail body for receiving the crossing screw.
6 more elements
An intramedullary implant system, comprising:
- an implant including a plate portion adapted for extramedullary fixation relative to a metatarsal bone and an integral intramedullary portion adapted for insertion into an intramedullary passage inside the metatarsal bone;
- a first row of retractable talons provided on the integral intramedullary portion and configured to deploy from a first position to a second position to increase a rotational stability of the implant,
- a second row of retractable talons provided on the integral intramedullary portion and configured to deploy from a first position to a second position to increase the rotational stability of the implant,
- wherein the second row of talons is located distal to the first row of talons along a length of the integral intramedullary portion;
- a first locking screw received through a first opening of the plate portion;
- a second locking screw received through a second opening of the plate portion;
- and
- a crossing screw received through a third opening of the integral intramedullary portion,
- wherein the crossing screw extends at a non-perpendicular angle relative to a longitudinal centerline axis of the integral intramedullary portion,
- wherein the plate portion is laterally offset from the longitudinal centerline axis of the integral intramedullary portion such that a majority of the plate portion is shifted laterally beyond both a first lateral side edge and a second lateral side edge of the integral intramedullary portion,
- wherein the integral intramedullary portion is configured in a shape of a nail body, and the third opening extends through the nail body for receiving the crossing screw.
