Abstract: The presented device is an orthopedic spinal cage that is inserted from an anteriorly aspect into a patient's intervertebral disc space. The device includes a cage to maintain vertebral separation and allow for fusion. Threaded screws allow for a matting and lag feature to prevent screw back out, provide a tactile event once fully inserted, and then to provide a stepped feature for reliable screw removal with minimal axial force. These features may be adapted to any orthopedic or other application requiring the thread screw features.

Abstract: This device is intended for orthopedic applications, particularly to treat a pars interarticularis fracture. The device is highly specialized to treat a common pars fracture with a uniquely contoured device that stabilizes the inferior fractured element with a generally conforming and non-linear hooked surface then transcribing the pars fracture to rigidly attach to the cortical bone between the facet and pedicle bones while applying compression across the fraction for fracture healing and stabilization.
