Abstract

A low-profile surgical rod implant device is provided that allows the length of a rod spanning two bone screws to be adjusted at the time of implantation. In a separate aspect of the invention, the rod implant device can be secured by tightening and securing an end of the rod implant device at one of the bone screws. Embodiments are provided for use with polyaxial pedicle screws and substantially straight shank pedicle screws in spinal applications. In a separate aspect of the invention, a bone screw connector having an interference type fit is also provided. A method for implanting the device is also provided.
