Abstract
The present disclosure provides an orthopedic device and method for carpal fusion that provides bone to bone compression and multiple fixation points to decrease multiple degrees of freedom and motion of carpal bones. The device is biocompatible, resistant to corrosion, and sufficient in mechanical strength. Bone to bone compression and fixation points can be increased by using a first set of fasteners in a peripheral portion of the device to couple through the device into bone structure, and a second set of fasteners in a central portion of the device can be coupled through the device into the bone structure.
Claims13
An orthopedic device for coupling a plurality of bones, comprising:
- a plate formed with a first set of openings located peripherally around the plate being closer to a periphery of the plate than a center of the plate and formed through the plate and a second set of openings located centrally on the plate being closer to a center of the plate than the periphery of the plate and formed through the plate at an angle to a longitudinal axis of the plate, the angle being configured to allow a plurality of second fasteners inserted in the second set of openings and coupled to the bones to pull radially inward the bones to provide compression between the bones.
A method of coupling an orthopedic device to a plurality of bones, the device having a plate formed with a first set of openings located peripherally around the plate being closer to a periphery of the plate than a center of the plate and formed through the plate and a second set of a plurality of openings located centrally on the plate being closer to a center of the plate than the periphery of the plate and formed through the plate at an angle to a longitudinal axis of the plate, the method comprising:
- locating the plate adjacent the bones;
- forming holes in the bones;
- inserting a first set of fasteners through the peripherally located openings and into the bones;
- inserting a second set of fasteners through the centrally located openings and into the bones;
- pulling the bones toward a longitudinal axis of the plate;
- and
- at least partially securing the bones toward a longitudinal axis of the plate with the second set of fasteners.
