Abstract
A spinal screw assembly includes a bone screw having a head with a rounded outer surface and an anchor portion for fixation to the bone. The assembly also includes a body member defining an internal cavity communicating with a bottom surface of the body member through a lower opening, with an interior surface adjacent the lower opening configured to engage the rounded outer surface of the head of the screw, and an upper portion defining a channel for receiving a fixation rod. The screw head is configured for uploading into the cavity of the body member through the bottom opening until the rounded outer surface enters into pivotal engagement with the interior surface of the internal cavity, with the screw extending downwardly through the lower opening, so as to allow for variable angular movement of the bone screw relative to the body member prior to locking the spinal screw assembly with a closure.
