Screw driver-holder apparatuses, systems and methods are provided and can include a screw and a screwdriver. The screw can include a threaded screw body and a screw head, and the screw head can include a socket and a screw head surface surrounding the socket. The screwdriver can include a hollow sleeve with a longitudinal bore and a first end defining a screw engagement surface and a driving shaft positioned within the longitudinal bore of the hollow sleeve and rotatable relative to the hollow sleeve. The driving shaft can further include a first end extending beyond the first end of the hollow sleeve, a second end opposite the first end, and a stop restricting axial movement of the sleeve towards the second end of the driving shaft. The first end can include a protruding tip adapted for engaging the socket of the screw head.

1. A screwdriver assembly comprising: a hollow sleeve comprising a longitudinal bore and a first end defining a screw engagement surface; anda driving shaft positioned within the longitudinal bore of the hollow sleeve and rotatable relative to the hollow sleeve, the driving shaft comprising: a first end extending beyond the first end of the hollow sleeve, the first end comprising a protruding tip adapted for engaging a corresponding socket in a head of a screw;a second end opposite the first end; anda stop with a substantially planar surface restricting axial movement of the sleeve towards the second end of the driving shaft. 2. The screwdriver assembly of claim 1, wherein the protruding tip extends beyond the first end of the hollow sleeve by a distance that is less than a depth of a corresponding socket on the screw. 3. The screwdriver assembly of claim 1, wherein the protruding tip comprises an externally-threaded outer surface adapted for engaging a corresponding threaded socket on the screw. 4. The screwdriver assembly of claim 1, wherein the screw engagement surface comprises a textured surface adapted to engage a textured surface of the head of the screw. 5. The screwdriver assembly of claim 1, wherein the screw engagement surface comprises one or more blades protruding from the first end and adapted to engage one or more corresponding slots in the head of the screw. 6. The screwdriver assembly of claim 5, wherein the one or more blades comprises two blades protruding from the first end on opposing sides of the protruding tip. 7. The screwdriver assembly of claim 5, wherein the one or more blades comprises four blades arranged in a cruciform pattern. 8. The screwdriver assembly of claim 1, comprising a lock movable to selectively link the hollow sleeve to the driving shaft for common rotation of the sleeve and the driving shaft. 9. A method for driving a screw comprising: positioning a driving shaft within a longitudinal bore of a hollow sleeve, the driving shaft rotatable relative to the hollow sleeve;connecting a screw to the driving shaft by engaging a protruding tip of the driving shaft with a corresponding socket in a head of the screw, wherein when the protruding tip is at least partially engaged with the socket of the screw, a first end of the hollow sleeve contacts the head of the screw;connecting the driving shaft to a drill to rotate one or both of the driving shaft or the hollow sleeve in a first direction to advance the screw; androtating the driving shaft in a second direction opposite the first direction to disengage the protruding tip from the socket of the screw. 10. The method of claim 9, wherein connecting a screw to the driving shaft comprises engaging an externally-threaded surface of the protruding tip with a corresponding threaded surface of the socket. 11. The method of claim 9, wherein rotating the driving shaft in the second direction to disengage the protruding tip from the socket of the screw comprises preventing rotation of the hollow sleeve to prevent reverse rotation of the screw. 12. The method of claim 9, comprising engaging the first end of the hollow sleeve with the head of the screw once the protruding tip is at least partially engaged with the socket of the screw. 13. The method of claim 12, wherein engaging the first end of the hollow sleeve with the head of the screw comprises engaging a textured surface of the first end of the hollow sleeve with a textured surface of the head of the screw. 14. The method of claim 12, wherein engaging the first end of the hollow sleeve with the head of the screw further comprises engaging one or more blades protruding from the first end of the hollow sleeve with one or more corresponding slots in the head of the screw. 15. A fixation system comprising: a screw comprising a threaded screw body and a screw head, the screw head comprising a socket and a screw head surface surrounding the socket; anda screwdriver comprising: a hollow sleeve comprising a longitudinal bore and a first end defining a screw engagement surface; anda driving shaft positioned within the longitudinal bore of the hollow sleeve and rotatable relative to the hollow sleeve, the driving shaft comprising: a first end extending beyond the first end of the hollow sleeve, the first end comprising a protruding tip adapted for engaging the socket of the screw head;a second end opposite the first end; anda stop with a substantially planar surface restricting axial movement of the sleeve towards the second end of the driving shaft. 16. The fixation system of claim 15 wherein the screw head surface comprises a textured surface; and wherein the screw engagement surface comprises a textured surface adapted to engage the textured surface of the screw head. 17. The fixation system of claim 15, wherein the screw head surface comprises one or more slots; and wherein the screw engagement surface comprises one or more blades protruding from the first end and adapted to engage the one or more slots. 18. A screw comprising a threaded screw body adapted for engagement of a material and a screw head, the screw head comprising an internally-threaded socket adapted for engaging an externally-threaded driving shaft of a screwdriver and a textured surface adapted to engage a textured surface of the screwdriver. 19. The screw of claim 18, wherein the screw head comprises one or more slots in the surface of the screw head adapted to engage one or more corresponding blades in the screwdriver. 20. A screwdriver assembly comprising: a hollow sleeve comprising a longitudinal bore and a first end defining a textured screw engagement surface adapted for engaging a textured surface of a head of a screw; anda driving shaft positioned within the longitudinal bore of the hollow sleeve and rotatable relative to the hollow sleeve, the driving shaft comprising: a first end extending beyond the first end of the hollow sleeve, the first end comprising a protruding tip adapted for engaging a corresponding socket in the head of the screw;a second end opposite the first end; anda stop restricting axial movement of the sleeve towards the second end of the driving shaft. 21. A screwdriver assembly comprising: a hollow sleeve comprising a longitudinal bore and a first end defining a screw engagement surface;a driving shaft positioned within the longitudinal bore of the hollow sleeve and rotatable relative to the hollow sleeve, the driving shaft comprising: a first end extending beyond the first end of the hollow sleeve, the first end comprising a protruding tip adapted for engaging a corresponding socket in a head of a screw,a second end opposite the first end, anda stop restricting axial movement of the sleeve towards the second end of the driving shaft; anda lock movable to selectively link the hollow sleeve to the driving shaft for common rotation of the sleeve and the driving shaft. 22. A method for driving a screw comprising: positioning a driving shaft within a longitudinal bore of a hollow sleeve, the driving shaft rotatable relative to the hollow sleeve;connecting a screw to the driving shaft by engaging a protruding tip of the driving shaft with a corresponding socket in a head of the screw, wherein when the protruding tip is at least partially engaged with the socket of the screw, a first end of the hollow sleeve contacts the head of the screw, such that a textured surface of the first end of the hollow sleeve engages with a textured surface of the head of the screw;rotating one or both of the driving shaft or the hollow sleeve in a first direction to advance the screw; androtating the driving shaft in a second direction opposite the first direction to disengage the protruding tip from the socket of the screw. 23.
