Bone cutting guide systems and methods
A bone cutting guide may include a support that contains a shaft movable relative to the support. The shaft may carry a guide member having one or more cut guides through which a clinician inserts a cutting member to cut bone positioned under the guide cut guides. In operation, a clinician may fixate the support of the bone cutting guide to a bone and translate the guide member until the one or more cut guides are positioned at a desired cut location. The clinician may then perform a cut through the cut guide. In some examples, the bone cutting guide includes additional components, such as bridging member or secondary cut guide, to provide additional functionality.
1. A bone cutting guide comprising:
a support having a length configured to be positioned parallel to a longitudinal axis of a metatarsal;
a main guide member located on an end of the support, the main guide member defining a first cutting slot configured to be positioned over a portion of the metatarsal to be cut;
a bridge component configured to extend outwardly from the support;
a secondary guide member configured to be located on and movable along the bridge component, wherein the secondary guide member defines a second cutting slot configured to be positioned over a portion of a cuneiform to be cut.
2. The bone cutting guide of claim 1 , wherein the support includes first and second extensions protruded outwardly from the length of the support.
3. The bone cutting guide of claim 1 , further comprising a first fixation aperture extending through the support, wherein a first fixation pin is configured to extend through the first fixation aperture to fixate the support.
4. The bone cutting guide of claim 3 , further comprising a second fixation aperture extending through the support, wherein a second fixation pin is configured to extend through the second fixation aperture to fixate the support.
5. The bone cutting guide of claim 1 , wherein the bridge component includes first and second rails extending out from the bridge component in a same direction.
6. The bone cutting guide of claim 1 , wherein:
the metatarsal is a first metatarsal,
the cuneiform is a first cuneiform, and
the bridge component includes a rail configured to extend over a joint between the first metatarsal and the first cuneiform.
7. The bone cutting guide of claim 1 , further comprising a fixation structure configured to be secured to the bridge component, the fixation structure providing a boundary to movement of the secondary guide member along the bridge component.
8. The bone cutting guide of claim 1 , wherein the bridge component comprises at least one rail.
9. The bone cutting guide of claim 1 , wherein the support includes a first fixation aperture configured to receive a first fixation pin proximate one end of the length and a second fixation aperture configured to receive a second fixation pin proximate an opposite end of the length.
10. A bone cutting guide comprising:
a support having a length configured to be positioned parallel to a longitudinal axis of a metatarsal;
a shaft movable relative to the support;
a main guide member located on an end of the shaft and movable as the shaft moves relative to the support, wherein the main guide member defines a first cutting slot configured to be positioned over a portion of a metatarsal to be cut;
a bridge component insertable into the first cutting slot and, when inserted into the first cutting slot, configured to extend outwardly from the support; and
a secondary guide member positioned on the bridge component, wherein the secondary guide member defines a second cutting slot configured to be positioned over a portion of a cuneiform to be cut.
11. The bone cutting guide of claim 10 , wherein the support includes first and second extensions protruded outwardly from the length of the support.
12. The bone cutting guide of claim 10 , wherein the shaft includes a proximal end positioned in the support and a distal end attached to the main guide member.
13. The bone cutting guide of claim 10 , wherein:
the metatarsal is a first metatarsal, and
the cuneiform is a first cuneiform.
14. The bone cutting guide of claim 10 , wherein the support includes a first fixation aperture configured to receive a first fixation pin proximate one end of the length and a second fixation aperture configured to receive a second fixation pin proximate an opposite end of the length.
15. The bone cutting guide of claim 10 , wherein the shaft is configured to slide relative to the support.
16. The bone cutting guide of claim 10 , wherein the shaft is configured to rotate relative to the support.
