Abstract
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.

A method of bone stabilization between an unstable bone and a stable bone, comprising:
- making a dorsal incision over a second, stable metatarsal of a foot;
- passing cerclage material into the dorsal incision, around the second metatarsal, and back out through the dorsal incision;
- threading the cerclage material through a dorsal loop of a bone stabilization plate;
- disposing the bone stabilization plate against a lateral cortex of the second metatarsal;
- tying the cerclage material around the second metatarsal and the bone stabilization plate in a cerclage fashion;
- making a medial incision along a first, unstable metatarsal of the foot;
- drilling a hole through the first metatarsal;
- creating a tunnel through soft tissue between the first metatarsal and the second metatarsal, the tunnel connecting the dorsal and medial incisions;
- passing free ends of the cerclage material through the tunnel from lateral to medial direction and pulling the free ends of the cerclage material through the hole in the first metatarsal;
- applying tension to the cerclage material while reducing angular deformity between the first and second metatarsals;
- and
- inserting a tenodesis screw medially in the hole of the first metatarsal, thereby fixing the cerclage material to the first metatarsal under tension.
A method of bone stabilization between an unstable bone and a stable bone, the method comprising:
- providing a plate body with a convex outer surface and a concave inner surface, the plate body having a dorsal loop disposed on the convex outer surface;
- disposing the plate body such that the concave inner surface abuts a lateral side of the second metatarsal bone of a foot;
- passing cerclage material through the dorsal loop and coupling it to the first metatarsal bone of the foot;
- and
- tightening the cerclage material to decrease an angular bone deformity between the first and second metatarsals.
A method of bone stabilization between an unstable bone and a stable bone, the method comprising:
- providing a bone stabilization device comprising:
- a plate body with a convex outer surface and a concave inner surface;
- at least one buttress wing extending perpendicularly from a longitudinal axis of the plate body;
- and
- at least one dorsal loop disposed on the convex outer surface of the plate body;
- disposing the bone stabilization device such that the concave inner surface of the plate body abuts the stable bone;
- passing cerclage material through the dorsal loop and coupling it to the unstable bone;
- and
- tightening the cerclage material.
A method of bone stabilization between a stable and an unstable bone, comprising:
- providing a bone stabilization system comprising:
- a plate body with a convex outer surface and a concave inner surface, the plate body having a dorsal loop disposed on the convex outer surface;
- cerclage material;
- a suture-passing instrument;
- a tenodesis screw;
- said bone stabilization system for:
- passing the cerclage material through the dorsal loop of the plate body;
- disposing the plate body such that the concave inner surface abuts a side of the stable bone;
- using the suture-passing instrument to pass the cerclage material through a hole in the unstable bone;
- tightening the cerclage material to secure the plate body to the stable bone;
- using the tenodesis screw to fasten the cerclage material to the unstable bone.
