Abstract
The present teachings provide one or more surgical implements for repairing damaged tissue, such as in the case of a spinal fixation procedure. A uniplanar bone anchor system for a fixation procedure is provided. The system can include a bone fastener including a head with a bearing surface and an engagement surface, and a shaft adapted to engage an anatomy. The system can include a saddle, which can include a first bore that receives the bone fastener and a coupling bore defined transverse to the longitudinal axis. The system can include a pressure cap received within the first bore having an engagement surface in contact with the engagement surface of the bone fastener. The system can further include a coupling system that can be received through the at least one coupling bore and can cooperate with the pressure cap to permit the bone fastener to move in only one plane.
