Screw inserter instruments and methods for implanting a bone screw are disclosed herein. In one exemplary embodiment, a screw inserter instrument can include a screw drive assembly having a first handle and a driver shaft coupled to the first handle, and a stylet assembly having a second handle and a stylet extending through the driver shaft. The first handle can have a locked configuration, in which the first handle and the driver shaft are coupled such that the first handle can maintain the driver shaft in a fixed position while the second handle is rotated relative to the first handle, and an unlocked configuration, in which the first handle and the driver shaft can rotate simultaneously in a first direction and the first handle can rotate independent of the driver shaft in a second opposite direction.
A screw inserter instrument, comprising:
The screw inserter instrument of claim 11, wherein, when the first handle is in the locked configuration, the locking ring is operably coupled to the driver shaft such that the first handle and the driver shaft are locked together.
The screw inserter instrument of claim 15, wherein, when the first handle is in the locked configuration, the first handle can maintain the driver shaft in a stationary position while the retaining sleeve can be rotated to threadably disengage from the bone screw, and when the first handle is in the unlocked configuration, the second handle can be held stationary while the first handle can be rotated in the first direction to rotate the driver shaft and retaining sleeve together to drive the bone screw into bone.
