Abstract
A low-profile surgical implant assembly is provided that includes a connector device that is an integral part of a rod, the connector device allowing the rod to be attached directly to a bone screw, such as a pedicle screw. Another aspect of the invention is a clamp device that allows the length of a rod spanning to attachment devices to be adjusted at the time of implantation, and further allows the clamp device to be secured by tightening a securing end of the clamp at the attachment device. The assemblies are useful for insertion into bone and connecting a foreign object to bone via a polyaxial coupling mechanism. A method for implanting the assembly is also provided.
