Bone fracture plate for tibia posterior medial plateau

Abstract

The invention discloses a bone fracture plate for a tibia posterior medial plateau which comprises a bone fracture plate body, the whole bone fracture plate body is in an L shape and is divided into a near plateau section and a far plateau section, the near plateau section is of an inwards-bent cambered surface structure and conforms to the anatomical structure characteristics of the tibia posterior medial plateau, and the far plateau section is of an inclined surface structure and a plane structure. The inclined surface structure is smoothly connected with the near platform section, the near platform section is sequentially provided with near platform kirschner wire holes and near platform locking holes from top to bottom, and the near platform locking holes are distributed in a row along the near platform section; the far platform section is sequentially provided with a far platform upper kirschner wire hole, a far platform upper locking hole, a far platform lower locking hole and a far platform lower kirschner wire hole from top to bottom. The width and the curvature are designed according to the anatomical structure of the tibia posterior medial platform, and the device is an anatomical locking plate and can be tightly attached to the bone cortex without intraoperative shaping, so that the strength of the bone fracture plate cannot be reduced, and the operation time cannot be prolonged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tibial posterior medial platform bone plate. Background technique [0002] The posteromedial tibial plateau fracture is a high-energy injury, which is rare in clinical practice. However, with the rapid development of my country's transportation and construction industries, the incidence of this disease is also increasing year by year. Patients with posteromedial tibial plateau fractures have complicated conditions, often accompanied by articular surface displacement, and are prone to misdiagnosis and misdiagnosis. In addition, the position is posterior and treatment is quite difficult. When the situation is more serious, the bone plate internal fixation is generally used to fix the fracture end. However, the existing osteosynthesis plates for posteromedial plateau fractures have many disadvantages, such as: no Kirschner wire holes are provided in the head of the bone p...

AI Technical Summary

Problems solved by technology

However, the existing osteosynthesis plates for posteromedial plateau fractures have many disadvantages, such as: no Kirschner wire holes are provided in the head of the bone plate, the bone plate cannot be temporarily fixed during the operation, it is difficult to initially position the joint cavity, and it is easy to place the locking screw When placed in the joint cavity, it is not convenient to fix and suture when the joint capsule is torn; there is no Kirschner wire hole at the distal end of the bone plate, and when the proximal end is fixed, the distal end tends to warp and does not fit the bone surface, which is not conducive to the temporary fixation and determination of the distal end. The position of the bone plate; there is no Kirschner wire hole in the body of the long bone plate, and when the fracture range is large and comminuted, the small bone fragment cannot be fixed; the back side of the bone plate is not provided with grooves, and the distribution of locking nail holes is relatively large. Many, although the fixation is stable, it affects the blood supply, which can easily lead to complications such as delayed union, nonunion, and wound infection; the bone plate is equipped with more locking holes, which can easily cause stress concentration and increase the risk of secondary fractures; the bone plate is longer, Unable to meet the needs of today's small incision minimally invasive surgery
