Orthopedic Fixation Device, System and Method

摘要

An implantable fixation device for rejoining opposed portions of a separated bone. The device including two corresponding plates that are configured to be aligned and coupled to a bone, such as a sternum, pre-resection of the bone or prior to cutting/separating the bone. The placement of the corresponding plates provides a gap between the edges of the plates that face one another allowing for and guiding a cutting tool for separating the bone. After the bone has been cut and the desired surgical procedure performed, the plates also assist in realigning and fixation of the bone portions. At least one plate includes a ratchet mechanism that is configured to tighten a locking element and draw the two plates together and into alignment with one another.

主权项

1. A device for guiding separation of and rejoining opposed portions of a bone, comprising:
a first plate configured to be disposed on and coupled to the bone, the first plate including: a first face; a ratchet mechanism on a top portion of the first plate facing away from the bone; and a first fastener aperture configured to receive a first fastener to couple the first plate to the bone; a second plate configured to be disposed on and coupled to the bone and spaced a distance from the first plate, the space allowing a cutting tool to be used to create a divide in the bone between the first and second plates, the second plate including: a second face configured to oppose and face the first face when the first and second plates are coupled to the bone; and a second fastener aperture configured to receive a second fastener to couple the second plate to the bone; and a locking element engageable with the ratchet mechanism and the second plate, the locking element configured to be coiled in response to operation of the ratchet mechanism and draw the first and second plates together to close the divide.
