Distal fibula C-type bone fracture band lateral wing locking setting structure

Abstract

A distal fibula C-type bone fracture band lateral wing locking setting structure including: a bone locking plate, a universal locking screw, a locking screw, and a compressing screw. The head portionof the bone locking plate is provided with a universal locking hole, a locking hole and a needle hole, which penetrate through the bone locking plate. A lateral wing, protruded to one side, is arranged on the body portion of the bone locking plate and is provided with a lateral wing sliding compressing hole which penetrates through the bone locking plate. A locking compression hole and a locking hole are formed in the body portion of the bone locking plate and penetrate through the bone locking plate. The locking screw, on the head portion of the bone locking plate, is fixed in a multidirectional manner so as to keep away from an articular surface, fixing strength being enhanced due to crossed fixation. The bone locking plate fits the fibula of human body and has good fitting ability and less influence on skin tension. By means of the lateral wing sliding compressing hole in the lateral wing, the structure can be fixed by implanting a compressing screw or by elastic structure of buttons and nylon wires, so that the structure is convenient to use in clinical operations.

Problems solved by technology

[0002] Fracture is one of the most common injuries. With the aging of the population, the annual incidence of fractures is gradually increasing. Fractures of the distal end of the fibula are common fractures. Kirschner wires, tension bands, screws, etc. The stable fixation of the distal end, especially for C-type fractures of the distal end of the fibula, there is no corresponding locking bone plate, and it cannot fully meet the requirements of reduction and fixation

Ordinary bone plates have certain fixation strength, but the conformability cannot be fully satisfied, and complications such as delayed skin healing are prone to occur. However, the existing anatomical bone plates or common locking bone plates do not have multi-angle fixation with screws. The screws are easy to loosen during use, which weakens the holding force, and the screws are easy to hit the articular surface, which makes clinical application difficult, affects the treatment effect, and brings pain to the patient
