Abstract

Embodiments of an orthopedic implant assembly include an apparatus having a receiver member and a fixation member. The receiver member includes first and second branches which define a channel extending along a longitudinal axis. The channel is configured to receive an elongated member. Additionally, the fixation member can include a threaded portion configured to engage bone. The orthopedic implant system can further include a one-step locking mechanism operably connected with the receiver member, the locking mechanism being configured to lock an elongated member in the channel. The locking mechanism includes a first closure device operably connected with the first branch and a second closure device operably connected with the second branch. The first and second closure devices are configured to cooperate with each other along a lateral axis to lock an elongated member in the channel. In certain embodiments, the lateral axis does not intersect the longitudinal axis.
