A cutting guide includes a first guide structure and a second guide structure. The first guide structure includes (i) a first base, (ii) a first saw support attached to the first base and defining a first saw contact surface, and (iii) a second saw support attached to the first base and defining a second saw contact surface that is spaced apart from the first saw contact surface so as to define a first elongated cutting slot therebetween. The second guide structure includes (i) a second base, (ii) a third saw support attached to the second base and defining a third saw contact surface, and (iii) a fourth saw support attached to the second base and defining a fourth saw contact surface that is spaced apart from the third saw contact surface so as to define a second elongated cutting slot therebetween.
