Distal fibular anatomic bone plate

Abstract

The invention relates to a bone plate, in particular to an anatomical bone plate for the flank of the distal end of the fibula. An anatomical bone plate for the distal side of the fibula, comprising a main body of the main body and a main body of the side wings, the main body of the main body is provided with 3 locking screw holes and 2 locking screw holes; the main body of the side wings includes a distal wing The plate and the front wing plate are designed in the shape of the bone plate that matches the human fibula, which fits better after installation and has less impact on skin tension. At the same time, a locking screw hole is designed on the distal end of the bone plate, so that the locking screw can be fixed in multiple directions. At the same time, through the design of the front wing plate and its screw hole, the screw can be fixed from the front side to the back side during fixation, avoiding entering the fibula The articular surface improves the strength of fixation, and it is convenient to apply in clinical operations, which reduces a lot of pain for patients.

Description

technical field [0001] The invention relates to a bone plate, in particular to an anatomical bone plate for the flank of the distal end of the fibula. Background technique [0002] Ankle fracture is a common intra-articular fracture, and it is one of the most important load-bearing joints of the lower extremity joints. The length and alignment of the lateral malleolus are the most important links in the rehabilitation of the ankle joint, followed by the repair of the medial malleolus and the inferior tibiofibular ligament. Studies have shown that 20% of the upward force in the gait posture is absorbed by the lateral ankle, so strong internal fixation of the fibula is necessary to restore the ideal length of the lateral malleolus and normal valgus angle, restore the anatomical relationship between the distal end of the fibula and the tibia, and maintain the lower tibiofibular joint. anatomy. The distal end of the fibula not only forms the inferior tibiofibular joint with ...

AI Technical Summary

Problems solved by technology

Kirschner wires, tension bands, screws, etc. lack strong fixation to the distal end of the fracture, and cannot fully meet the requirements of reduction and fixation

Although the ordinary bone plate has a certain fixing strength, it must be shaped, which affects the strength of the plate, and is thicker, and the suture tension of the skin is high, which is prone to complications such as delayed skin healing and infection, especially for comminuted fractures of the distal fibula , bone fragments far from the syndesmosis or osteoporotic comminuted fractures, the distal fractures are still difficult to meet the requirements of fixation

The existing anatomical bone plate or ordinary locking bone plate does not have multi-directional fixation with screws. For distal comminuted fractures or decreased bone density, the screws are easy to loosen, the holding force is weakened, and the screws are easy to enter the joint cavity. Cause clinical application difficulties, affect the therapeutic effect, and cause pain to patients
