Winged tether plate and method of use for reducing angular bone deformity

摘要

The present invention is a method and device for the correction and reduction of bone deformities, such as metatarsus primus adductus, using a plate body with winged buttresses and dorsal loop. The method and device can be affixed to a bone without any drilling or violating of the bone and can use a tethering technique which does not require drilling into the second metatarsal, nor does it require the placement of a prominent suture knot/button device medially along the first metatarsal.

主权项

1. A winged looped plate device comprising:
a plate body with an outer surface and an inner surface; at least one pair of buttress wings, each wing extending from an opposite side of the plate body and directly aligned with each other, such that a longitudinal axis of the pair of buttress wings is perpendicular to a longitudinal axis of the plate body; and at least one dorsal loop disposed on the outer surface of the plate body for threading of cerclage material through the at least one dorsal loop and tied around the device and a bone such that tension applied to the cerclage material secures the plate device to the bone to prevent displacement of the plate body, wherein the position of the at least one dorsal loop is immobile with respect to the plate body, and wherein the dorsal loop defines a channel, and an axis extending through the channel is perpendicular to the longitudinal axis of the plate body and is directly aligned with the longitudinal axis of the pair of buttress wings such that the cerclage material, once threaded through the at least one dorsal loop, extends along an axis perpendicular to the longitudinal axis of the plate body and is directly aligned with the longitudinal axis of the pair of buttress wings, and the cerclage material extends over an outer surface of each buttress wing along their longitudinal axis.
