A spinal fixation device includes a bone screw, a tulip-shaped seat, a rod seat, and a washer. The bone screw comprises a spherical head and a threaded elongated body extending along a first direction. The tulip-shaped seat comprises a bottom portion that has a through-opening shaped and dimensioned to receive the bone screw so that an inner surface of the bottom portion engages the spherical head of the bone screw and prevents the bone screw from passing entirely through the through-opening, while the spherical head remains polyaxially rotatable within the bottom portion of the tulip-shaped seat. The rod seat sits within and engages the inner surface of the tulip-shaped seat and the rod seat comprises a semispherical bottom that is shaped and dimensioned to engage the spherical head of the bone screw while the spherical head remains polyaxially rotatable within the bottom portion of the tulip-shaped seat. The washer is ring-shaped and comprises a through-opening shaped and dimensioned to receive the threaded elongated body of the bone screw and an upper portion shaped and dimensioned to snappably-engage an outer surface of the tulip-shaped seat.

System and method for spinal fixation via a trans-facet pedicle screw assembly

A system for performing a laminoplasty procedure in a spinal vertebra includes an implant and an inserter tool. The implant is configured to be placed on a previously formed lamina opening of the spinal vertebra, and is shaped and dimensioned to be placed in the lamina opening after the opening has been distracted. The inserter tool is configured to insert the implant near the lamina opening and then to distract the lamina opening so that the lamina opening is dimensioned to receive the implant and then to place the implant into the distracted lamina opening while simultaneously holding the lamina opening in a distracted state.

System and method for spinal decompression

An implantable cervical plate assembly includes a cervical plate, one or more bone fasteners. The cervical plate comprises an elongated asymmetric body having one or more through-openings extending from the front surface to the back surface of the elongated asymmetric body. The one or more bone fasteners are configured to be inserted through the one or more through-openings, respectively. The bone fasteners comprise a threaded main body and a head that includes one or more breakable structures configured to be broken when inserted into a groove and then unflex and remain captured within the groove.
