摘要：
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.
