Pedicle Screw Washer

Technology #2014-268

Spinal instrumentation surgeries can often include the use of one or more pedicle screws. The pedicle screws are typically cancellous bone screws and can sustain high loads, which may render them susceptible to failure by loosening or pullout. Various devices and methods have been developed for locking or fixating pedicle screws; however, most of these devices and methods include complicated coupling elements that are often made up of multiple parts. The multitude of parts can increase the complexity and time required of the spinal surgeries. Therefore, it would be desirable to have a system that increases the structural stability of a pedicle screw without increasing the complexity, or the time, required of a surgical procedure used to install the pedicle screw. The aforementioned shortcomings can be overcome by the orthopedic fixation system of this invention. This orthopedic fixation system includes a pedicle screw washer, which includes a body, an aperture for receiving a pedicle screw, a first securing member extending from the body spaced from the aperture and dimensioned to engage a first side of a transverse process of a vertebrae, and a second securing member extending from the body spaced from the aperture and dimensioned apart from the first securing member to engage a second opposed side of the transverse process of the vertebrae.
