Abstract
Osteotomy fixation systems and surgical methods are provided herein. A fixation system can comprise a body, a curved portion, a dorsal extension, a medial extension, and at least three fixation holes. The curved portion can be configured to conform to a curvature of a first cuneiform. The dorsal extension can be configured to conform to a curvature of a dorsal side of a first metatarsal. The medial extension can be configured to conform to a curvature of a medial side of the first metatarsal.
Claims16
A device comprising:
- a body comprising a curved cuneiform portion coupled to a proximal end of a dorsal extension, and a proximal end of a medial extension, and at least five fixation holes, wherein:
- the fixation holes are each configured to receive a fixation device;
- at least one fixation hole extends through the curved cuneiform portion, at least one fixation hole extends through the dorsal extension, and at least one fixation hole extends through the medial extension;
- the curved cuneiform portion is configured to wrap around and conform to a metatarsal flare;
- at least one fixation hole through the cuneiform portion is polyaxial;
- the dorsal extension is configured to span a joint and the medial extension is configured to span the joint;
- and
- a first line tangent to a distal end of the dorsal extension is approximately perpendicular to a second line tangent to a distal end of the medial extension.
A device comprising:
- a body comprising a curved cuneiform portion coupled to a proximal end of a dorsal extension, and a proximal end of a medial extension, and at least five fixation holes, wherein:
- at least one fixation hole extends through the curved cuneiform portion, at least one fixation hole extends through the dorsal extension, and at least one fixation hole extends through the medial extension;
- each fixation hole is configured to receive a fixation device;
- each fixation hole defines a respective insertion area;
- the curved cuneiform portion is configured to wrap around and conform to a metatarsal flare;
- at least one fixation hole through the cuneiform portion is polyaxial;
- the dorsal extension is configured to span a joint and the medial extension is configured to span the joint;
- and
- a first line tangent to a distal end of the dorsal extension is approximately perpendicular to a second line tangent to a distal end of the medial extension, the dorsal extension is configured to conform to a dorsal curvature of the first metatarsal, and the medial extension is configured to conform to a medial curvature of the first metatarsal;
- a first distal end of the dorsal extension defines a first angle and a second distal end of the medial extension defines a second angle;
- the first angle and the second angle intersect in a frontal plane at an angle in a range of 80 degrees to 100 degrees.
