摘要： The invention relates to an osteosynthesis device with a bone plate and with at least one bone screw, wherein the bone plate has at least one through-hole with a conical inner thread formed at least in part in the through-hole. Moreover, the bone screw has a screw shank and also a screw head with a conical thread, with the possibility of forming a connection at a variable and stable angle between bone screw and bone plate by receiving the screw head with conical outer thread in the respective through-hole of the bone plate. According to the invention, the thread in the screw head has a first portion A with a first conicity and a second portion B with a second conicity, wherein a zone of discontinuity with respect to the conicity is present between the first portion A and the second portion B.

摘要： The invention relates to a bone plate (1), comprising a bottom side (4) intended for lying against the bone, a top side (3) facing away from the bone, a plurality of holes that penetrate the plate, of which holes at least one hole is used to accommodate a bone screw that has or does not have a threaded screw head, wherein furthermore at least one of the holes has a spherical oblong-hole shape having a threaded section. According to the invention, the at least one oblong hole has a thread having at least one thread turn on the overall inner peripheral side, wherein the at least one thread turn is not interrupted in a first pitch circle region (A) and is interrupted by thread-free recesses (6) in a second pitch circle region (B) and furthermore the thread has a conical shape in the first pitch circle region and the thread extends from the plate bottom side to the spherical formation in the second pitch circle region, wherein the section of the spherical recess extending to the plate top side is likewise thread-free.
