Abstract
A system for providing fixation of first and second bones includes a drill guide that receives a drill bit to create first and second holes in the first and second bones, respectively. Guide pins can be driven into the first and second holes. The guide pins are received by a surgical saw to guide the surgical saw toward a joint between the first and second bones, thereby creating a third hole in each of the bones across the joint. The guide pins are then removed, and an implant can be inserted into the bones, such that a first leg of the implant is disposed in the first hole, a second leg of the implant is disposed in the second hole, and a keel of the implant is disposed in the third hole.
Claims16
A method of joining two bones, the method comprising:
- driving first and second guide pins into respective first and second bones, such that the first and second guide pins are disposed in first and second holes, respectively of the first and second bones;
- attaching a saw guide to a surgical saw, the saw guide comprising:
- a distal portion that defines first and second guide holes configured to receive the first and second pins, respectively, and a slot positioned between the first and second guide holes configured to receive a saw blade of the surgical saw;
- a proximal portion comprising a proximal opening configured to receive a blade attachment assembly on the surgical saw;
- and
- a side-facing opening through which a portion of the blade attachment assembly slides when the blade attachment assembly is inserted into the proximal opening of the saw guide;
- wherein attaching the saw guide to the surgical saw comprises inserting the saw blade and blade attachment assembly into the proximal opening of the saw guide prior to sliding the saw guide over the first and second guide pins;
- after the driving step, inserting the first and second guide pins into the first and second guide holes, respectively, such that the saw blade of the surgical saw is aligned with a target cut location that is defined by either or both of the first and second bones;
- guiding movement of the surgical saw along the first and second guide pins to the target cut location, such that the saw blade creates an intermediate slot at the target cut location between the first and second holes;
- removing the surgical saw and the first and second guide pins;
- and
- inserting an implant into the first and second holes, such that a keel of the implant is inserted into the intermediate hole,
- wherein the saw guide comprises a side-facing opening through which a portion of the blade attachment assembly slides when the blade attachment assembly is inserted into the proximal opening of the saw guide.
A surgical saw guide, comprising:
- a distal portion that defines first and second guide holes configured to receive first and second pins, respectively, and a slot positioned between the first and second guide holes and configured to receive an oscillating saw blade;
- a proximal portion comprising a proximal opening configured to receive a blade attachment assembly of a surgical saw;
- and
- a side-facing opening configured to slidably receive a portion of the blade attachment assembly,
- wherein the side-facing opening comprises a proximal portion having linear edges and a distal portion having a curved edge, and a width between opposing curved edges is greater than a width between the linear edges.
