There are roughly two structures of existing locking compression plates. One is that the pressure hole and the locking hole are independent and separate; the other is that the pressure hole and the locking hole are connected together, that is, the through hole is composed of the overlapping parts of the pressure hole and the locking hole, that is, the center of the terminal end of the pressure hole does not coincide with the center of the locking hole.

[0003] Publication number CN202714914U discloses a locking and pressurizing bone plate device, characterized in that it comprises a locking bone plate, a pressurizing hole, a locking screw and a pressurizing screw. The locking bone plate is evenly provided with several pressurizing holes, and the locking screw and the pressurizing screw are locked with pressurizing respectively. It can minimize the contact area with the bone surface without weakening the mechanical strength of fixation, can effectively protect the blood flow of the bone cortex under the bone plate and the arrangement of collagen, and prevent the occurrence of osteoporosis under the plate in the later stage of plate fixation; the fixation is reliable, and the fracture healing speed and quality are better than ordinary plate fixation. It uses spherical holes to achieve pressurized stability, and the threaded matching parts of the locking bone plate and the locking bone screw realize restrictive locking, retaining the gap between the bone plate and the bone surface, avoiding the shortcomings of ordinary bone plates that bring obstacles to fracture healing, increase the chance of infection, and be used with caution for osteoporosis and comminuted fractures.
