Inner anklebone anatomical plate

Abstract

The invention discloses an inner anklebone anatomical plate. The inner anklebone anatomical plate comprises a plate body which is laminated and fixed at a far end of a shin bone; a plurality of firstscrew holes are distributed on the plate body; a position, toward a shin bone hypozygal face, at the periphery of the plate body is expanded outward to form an expanding part; a common face of the plate body and the expanding part is concave inward to form a covering surface for laminating an outer peripheral wall of the far end of the shin bone; the peripheral edge, toward an inner anklebone, ofthe expanding part extends outward to form an extending part for laminating the inner anklebone; a plurality of second screw holes are distributed on the extending part. The inner anklebone anatomicalplate disclosed by the invention has the following advantages and effects that an inner anklebone fracture part can be supported and fixed better, so that the fracture part is healed better.

Description

technical field [0001] The invention relates to a medical device, in particular to an anatomical steel plate for the inner malleolus. Background technique [0002] With the development of society and the increase of vehicles, injuries caused by traffic accidents and complex fractures and traumas also increase, and complex fractures are also common, especially adduction-type Pilon fractures and supination-adduction-type medial malleolus fractures. The main problems in the treatment of such fractures are as follows: 1. Simple hollow screws are difficult to fix reliably, and the medial anatomical plate support is required to provide reliable biomechanics; 2. The collapse of the medial articular surface of the distal tibia is difficult to deal with. There is no reliable internal fixation device after bone grafting, which increases the difficulty of internal fixation in clinical operations. The existing internal fixation methods using screws and other common steel plates have fai...

Problems solved by technology

[0002] With the development of society and the increase of vehicles, injuries caused by traffic accidents and complex fractures and traumas also increase, and complex fractures are also common, especially adduction-type Pilon fractures and supination-adduction-type medial malleolus fractures. The main problems in the treatment of such fractures are as follows: 1. Simple hollow screws are difficult to fix reliably, and the medial anatomical plate support is required to provide reliable biomechanics; 2. The collapse of the medial articular surface of the distal tibia is difficult to deal with. There is no reliable internal fixation device after bone grafting, which increases the difficulty of internal fixation in clinical operations. The existing internal fixation methods using screws and other common steel plates have failed to achieve the purpose of fixation

Since the steel plate cannot cover the fracture site, it will be difficult to heal the fracture site or prolong the healing time, and more seriously, it will cause fatigue fracture of the steel plate, which will lead to further fracture dislocation, bringing mental pain and economic burden to the patient
