ABSTRACT:
A threaded connection for medical implants utilizes root and crest interfnce profile, such that the major and minor diameters of the thread profile on the male and female members of the connection are selected such that the minor diameter of one member is larger than the major diameter of the other, such that an interference condition is created along the helical path of the thread. This interference condition increases the radial stability of the connection and increases the torque required to loosen the connection when made up.
