The bone drill also includes a cannulated sheath with a proximal end and a distal end, the sheath housing a portion of the shaft and having a curved portion at the distal end. The drill tip may also be housed within the curved portion of the sheath. The bone drill may also include a hub with an actuator mechanism, the hub being coupled to the sheath, wherein the actuator mechanism retracts the sheath to cause the drill tip to extend beyond the distal end of the sheath.
