摘要:
Systems, tools, and screws for reducing a bone fracture are disclosed. In embodiments, the system comprises: a screw, a driver, a sleeve comprising a longitudinal bore configured to enable insertion of the driver through the sleeve, a locking mechanism configurable into a first state that locks the sleeve to the driver and a second state that unlocks the sleeve from the driver, and a retaining sleeve coupled to a first end of the driver and configured to couple to the screw. In the first state, the sleeve applies a compressive force while distal threads of the screw are driven into the bone while retaining proximal threads of the screw in the sleeve. After a desired compression is achieved, the locking mechanism is configured to the second state, allowing the proximal threads of the screw to be driven into the bone while maintaining application of the compressive force to the bone.
