Abstract: A staple implant is for influencing or guiding the growth in bone regions bordering the epiphyseal plate, said staple having a transverse web and anchoring limbs arranged on the ends of the transverse web, running parallel to one another and terminating in points. The anchoring limbs, once inserted into the bone, form fixation points on one side of said bone on either side of the epiphyseal, plate. The transverse web has at least one narrowed zone that can be plastically deformed under a flexural load, said zone having any position and form without abrupt transitions and being situated between the fixation points.

Abstract: A bone plate system for osteosynthesis comprises a bone plate, a swivel screw, a clamping screw, a swivel hole formed in the bone plate as a through hole for receiving the swivel screw polyaxially, and a clamping hole, which is associated with the swivel hole and is formed in the bone plate as a further through hole for receiving the clamping screw. When the swivel screw and the clamping screw are screwed in, they are fixed with angular stability in multiple dimensions, as the screw heads of the swivel screw and of the clamping screw are secured by one another and by the bone plate against relative movement. The swivel screw and the clamping screw are each designed as a bone screw.

Abstract: Apparatus for the fixed-angle fixation and compression of a fracture site or osteotomy of a bone includes a bone plate having a plurality of holes and bone screws with a threaded head. The bone screws accommodated in the holes are screwed into the bone. At least one of the holes is a combination of two circular holes of different diameter. As screwing of the bone screw into the bone proceeds through a final stage, engagement of the threads on the head with threads in the combination hole effects relative longitudinal displacement between the plate and the bone whereby it is possible to simplify simultaneous fixed angle fixation and compression of the fracture or osteotomy with use of a single screw. Threads on the head of the bone screw engage threads in the hole which is a combination of the two hole to effect relative motions.
