Abstract

A polyaxial instrument suitable for preparing the intervertebral disc space of a patient through an anterior, posterior, transforaminal or anterolateral approach. The trial can be partially inserted into a disc space and then its angle adjusted to ease its further insertion into the disc space. The trial work tip can be interchangeable with the working tip of another type of instrument such as a curette, a rasp, a spreader, a shaver, a cobb elevator, a penfield, a woodson, a chisel and an osteotome.
