Abstract
Disclosed is a combined intramedullary and extramedullary bone stabilization and alignment system, which includes both methods and apparatuses for the alignment and stabilization of a first bone or piece of bone to a second bone or piece of bone. Embodiments of the system may include an implant device which has an elongated framework within the intramedullary portion and an extramedullary portion which are cannulated. The cannulated aspect of the framework includes a wire aperture through both the intramedullary portion and the extramedullary portion.
Claims16
An implant alignment tool for use in combination with an implant device, configured for aligning an implant device configured for use as a medial bunion plate or a Hallux Limitus/Dorsal Bunion Plate, in a patient being implanted to stabilize a first bone section relative to a second bone section of a patient, the implant alignment tool comprising:
- a handle;
- a proximal screw guide portion extending from said handle;
- and
- an implant device attachment portion.
A method to re-align and stabilize a patient's metatarsal bone comprising:
- assessment of a deformity to be remedied, including the desired translational and rotational correction
- make incision to expose the metatarsal bone;
- remove a medial bone to create an appropriate surface for receiving a portion of an implant device;
- create an osteotomy in a first metatarsal bone behind the sesamoids;
- translate the metatarsal head laterally and rotate head to the desired position in all planes;
- place a guide wire into a shaft of the metatarsal bone to locate the metatarsal head into a desired position;
- providing an implant device comprised of:
- an elongated framework including an intramedullary portion and an extramedullary portion,
- the extramedullary portion including at least one fastener aperture disposed to transversely receive a bone fastener to affix the extramedullary portion to the second piece of the first metatarsal bone;
- and
- a contiguous wire aperture axially through the intramedullary portion;
- place the extramedullary portion over the guide wire and into the shaft of the metatarsal;
- fixate the extramedullary portion to the metatarsal head with one or more fasteners;
- attach a drill guide over the wire and fast the drill guide to the extramedullary portion;
- evaluate and adjust the alignment of the metatarsal head utilizing the implant adjustment tool;
- drill proximal fastener apertures in the metatarsal bone;
- and
- place proximal fasteners into the metatarsal bone.
