Tibia far-end front and outer side bone fracture plate

Abstract

The invention discloses a tibia far-end front outer side bone fracture plate which comprises a bone fracture plate body, the bone fracture plate body comprises a bone fracture plate near end and a bone fracture plate far end, the whole bone fracture plate body is in an L shape, the bone fracture plate far end is divided into a bent section and an inclined plane connecting section, the bent section is provided with a far end locking hole and a far end kirschner wire hole. A plurality of far-end lower locking holes and far-end lower kirschner wire holes are formed in the inclined plane connecting section, a sliding hole is formed in the left end of the bone fracture plate near end, a near-end kirschner wire hole is formed in the right end of the bone fracture plate near end, a plurality of near-end middle locking holes, a sliding hole I and a near-end locking hole are sequentially formed between the near-end kirschner wire hole and the sliding hole. The near-end middle locking holes are arranged. A near-end middle Kirschner wire hole is formed between every two adjacent near-end middle locking holes. The curvature radius of the far end of the bone fracture plate is determined according to ankle joint data of Chinese people, the situation that the inner side of the far end of an existing bone fracture plate tilts due to the fact that the curvature radius is too large is avoided, and complications such as conscious discomfort or soft tissue irritation of postoperative patients are reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anterolateral bone plate at the distal end of the tibia. Background technique [0002] Distal tibial fractures refer to the fracture line located at the distal end of the tibia, among which pilon fractures are difficult to treat and have a poor prognosis. Pilon fracture refers to the fracture of the distal 1 / 3 of the tibia that spreads to the tibiotalar articular surface. Pilon fractures are mostly fractures that occur under the combined action of axial external force and rotational external force, and are accompanied by bone defects and cancellous bone compression. In recent years, with the development of my country's economy, transportation, and urban architecture, the incidence of Pilon fractures has gradually increased. Pilon fractures will involve the distal end of the tibial bone on the tibiotalar articular surface of the patient. After the fracture, it will hav...

AI Technical Summary

Problems solved by technology

Pilon fractures will involve the distal end of the tibial bone on the tibiotalar articular surface of the patient. After the fracture, it will have a serious impact on the patient's mobility and quality of life. This type of fracture is one of the most difficult types of fractures to treat. Internal fixation is mostly used for treatment, but the existing bone plate has insufficient fixation strength, which easily leads to loss of reduction; the bone plate is large in size, causing too much damage to soft tissue and blood supply; the distal and proximal ends of the bone plate are easy to warp, causing shock The soft tissue is disturbed; the radius of curvature of the distal end of the bone plate is too large, which does not conform to the anatomical characteristics of Chinese people, and may easily cause postoperative discomfort and other problems for patients
