Abstract
The present invention is directed to improving bonding between orthopedic devices, particularly vertebral devices, and bone. The present invention provides various methods and devices employing mechanical and bio-fixation modalities for such attachment. As provided herein, the initial mechanical attachment of a device to bone is sufficiently stable to ensure that the implanted device is relatively immobile (or alternatively microscopic motion is promoted), facilitating bone and soft tissue in-growth and the eventual bio-fixation of the device.
Claims26
A method for securing a device to bone comprising:
- using a fixation device having at least a first fixation region and at least a second fixation region-wherein the first fixation region is adapted for initial mechanical attachment of the device to bone for facilitating biological ingrowth into the second fixation region.
The method of claim A13 wherein the mechanical fixation structure is a strut.
An orthopedic device comprising:
- a first attachment region having one or more mechanical structures that are adapted to securely attach said device to bone;
- and a second attachment region which is adapted to facilitate bio-fixation of the device.
A method of implanting a fixation device into a patient's vertebra to promote bio-fixation of said device comprising:
- implanting the device having an elongated body wherein a portion of the elongated body is positioned within a cancellous bone region of the vertebra and a second portion of the elongated body is positioned within a cortical bone region.
A method of attaching an orthopedic device into bone, said method comprising:
- implanting an anchoring device into bone;
- promoting bio-fixation of the anchoring device to provide sufficient load bearing support;
- and
- coupling the anchoring device to the orthopedic device.
