Non-contact arcuated stress bone plate for epiphysis

Abstract

The invention provides a non-contact capitulum curved stress bone fracture plate. The plate is fixed on a catagmatic part through novel bone screws with 0.3 to 0.5 mm of distance between the bone fracture plate and the bone; the non-contact fixing mode is adopted, so the periosteum cannot be peeled off and also cannot become necrosis caused by pressing, thereby ensuring that the catagmatic part has good blood supply, and promoting the healing of the catagmatic part. The stress deformation movement of the fixing section curved structure transfers the stress to the catagmatic end, so that the bone after fracture fixation can also be stimulated by appropriate stress to accelerate healing and reduce complication. The plate has the advantages of shortening the healing time and achieving biological fixation.

Description

technical field [0001] The invention belongs to the field of orthopedic orthopedics in clinical medicine, and is used for fixing fractures and orthopedics and promoting fracture healing. Background technique [0002] We know that under the guidance of AO theory, the current surgical orthopedic bone plates used to treat fractures are mostly strong compression internal fixation, the fracture healing quality is poor, and there are many complications, because (1) the current bone plates are used in the treatment of fractures or During orthopedic treatment, strong pressure internal fixation is used, which is closely attached to the surface of the bone, resulting in the compression and necrosis of the periosteum supplying the blood supply of the fracture end, and further destroying the blood supply of the fracture end damaged by the fracture, resulting in the above complications and prolong the healing time and even lead to nonunion; (2) The stress shielding caused by strong inter...

[0002] We know that under the guidance of AO theory, the current surgical orthopedic bone plates used to treat fractures are mostly strong compression internal fixation, the fracture healing quality is poor, and there are many complications, because (1) the current bone plates are used in the treatment of fractures or During orthopedic treatment, strong pressure internal fixation is used, which is closely attached to the surface of the bone, resulting in the compression and necrosis of the periosteum supplying the blood supply of the fracture end, and further destroying the blood supply of the fracture end damaged by the fracture, resulting in the above complications and prolong the healing time and even lead to nonunion; (2) The stress shielding caused by strong internal fixation makes the fracture end lose the sine wave stress stimulus needed for bone growth, and delayed union or even bone nonunion is common in clinical practice; even if healed, The time is also greatly extended, compared with traditional Chinese treatment methods, the time is extended by 30%
