ABSTRACT:
A surgical implant or instrument has two parts, one sliding on the other, the lower part being provided with a threaded bore and the upper part being provided with a passage orifice for receiving a fixing screw. The set screw can be received over its entire length beneath the upper part in the threaded bore and includes, at its upper end, a dog point which is thinner than its threaded part and which is provided with a slit, groove or hexagon socket for a screwdriver, the diameter of the passage orifice being smaller than that of the threaded part and larger than that of the dog point. An elastic device is provided for the implant or instrument which pushes the fixing screw into the fixing position.
