CONNECTOR FOR FRACTURED BONES

摘要

A sleeve is to be inserted into a fractured bone bridging the fracture thereof. The leading end portion is then to be located in one bone fragment and the open trailing end portion is to communicate with the exterior of the other bone fragment. An expander screw is threaded into the sleeve and has a head which bears exclusively upon an annular shoulder provided on the sleeve. The front end of the expander screw serves, by its configuration or by cooperation with an expander element, for expanding the leading end of the sleeve so as to retain it in the bone fragment in which it is located. A cap screw is threadedly connected with and closes the trailing end portion of the sleeve, bearing upon the other bone fragment and thereby drawing the two fragments together via the intermediary of the sleeve.
