Abstract

The device is particularly for osseous synthesis, where a plate is secured to a support by a screw engaging in a tapped hole. Each screw fits in a tapped bush, whose thread is of the same pitch as that of the screw, although the external thread of the bush is of finer pitch. The plate has one or more holes tapped with the same thread as the external thread of the bush. Where the plate surface is entirely smooth, the height of the bush can be equal to or less than the plate thickness. Where used to join two bone fragments together, the screw can be screwed into the plate and the two bone fragments.
