摘要: The term self-tapping screw refers to screws which are inserted into a predrilled hole directly without first tapping thread. A self-drilling would refer predrilling function similar threaded K-wire. Selftapping further subdivided threadfarming and thread-cutting screws. former forms its thread by elastic-plastic deformation or local destruction of the bone, latter cutting through bone simultaneously performing tap. AO/ASIF has opposed use selftapping in cortical for many years had good reason do so.
