Abstract
Abstract A system for performing osteotomies includes a bone plate and a retractor assembly. The bone plate generally includes a first mounting portion for attachment to a first bone portion, a second mounting portion for attachment to a ssecond bone portion, and an intermediate portion connecting the first mounting portion and the second mounting portion. The retractor assembly includes first and second handle members coupled for relative movement about a first pivot axis and first and second jaw members coupled to the first and second handle members, respectively.
