Problems solved by technology

[0003] The existing type of bone plate is difficult to be firmly fixed due to reasons such as shape and screws, and it is likely to cause displacement of the fracture fragment during early exercise
On the other hand, syndesmosis of the inferior tibiofibular joint requires high surgical skills for the operator, and inexperienced young doctors cannot accurately adjust the direction of the cortical screw, which may easily cause postoperative ankle pain; on the other hand, due to the existing bone The sliding holes on the plate are not set at a specific angle, and the cortical bone screw can easily cause the distal end of the fibula to move anteriorly and medially

Abstract

The invention discloses a fibula far-end outer side bone fracture plate. The fibula far-end outer side bone fracture plate comprises a bone fracture plate body, wherein the bone fracture plate body is divided into a near-end section and a far-end section, the near-end section and the far-end section are in smooth transition and are in curved surface connection, the far-end section is in an expanded shape and is attached to the far end of a fibula, the far-end section is in an expanded shape and is attached to the far end of the fibula, a near-end upper kirschner wire hole, near-end upper locking holes, a sliding hole, near-end lower locking holes, a sliding hole I and a sliding hole II are sequentially formed in the near-end section from right to left, a plurality of near-end lower locking holes are formed, near-end lower kirschner wire holes are formed between the adjacent near-end lower locking holes, a plurality of far-end locking holes are formed in the far-end section and are distributed along an annular structure, the far-end upper kirschner wire hole is formed in the middle of the annular structure, and a plurality of far-end lower kirschner wire holes are formed in the left end of the far-end section along the circumference. The width and the angle of the device are designed according to the anatomical form of the far-end bone surface of the fibula, and the device is an anatomical locking bone fracture plate and can be tightly attached to the surface of bone cortex without intraoperative shaping.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone plate for the outer side of the distal end of the fibula. Background technique [0002] Fractures of the distal fibula near the ankle joint are also called lateral malleolus fractures. In recent years, more and more attention has been paid to the fixation of distal fibula fractures, and early functional exercise is regarded as the most important thing in fracture treatment. Therefore, reliable fixation of the fracture end and inferior tibiofibular syndesmosis is the key to early functional exercise. The anatomical structure of the distal fibula has a valgus angle of 13-15°, which increases the difficulty of surgery. Insufficient fixation of the distal fibula or injury of the inferior tibiofibular syndesmosis will cause instability of the ankle joint, causing the distal fibula to move outward, and the talus The subsequent outward movement can lead to ankle injury a...
