Abstract
A trial implant system including a trial implant configured to be temporarily inserted into an intervertebral space defined by a superior vertebral body and an inferior vertebral body is disclosed. The trial implant may include a superior plate and an inferior plate coupled to the superior plate. The superior plate may have a first mating portion that defines a first articulating interface and the inferior plate may have a second mating portion that defines a second articulating interface. The second articulating interface may be configured to interact with the first articulating interface of the superior plate such that at least one of the superior plate and the inferior plate is capable of movement relative to the other. The first and second articulating interfaces may be primary or auxiliary articulating interfaces. For example, the first and second articulating interfaces may be corresponding curved surfaces or they may be corresponding engagement features.
