Distal humeral outer plate

Abstract

The invention provides a distal humeral outer plate which comprises a head component and a rod component. The head component and the rod component are of integral structures, and the head component isfixedly attached to distal humeral outer ridges and outer rear bone surfaces; head screws are in angular designs, capitulum humeri and traversing pulleys can be simultaneously fixed by the aid of thehead screws, and effects of clamping the pulleys from the outer side can be realized. The rod component extends towards proximal humeri along the humeral outer ridges and is fixedly attached to humeral shafts. The distal humeral outer plate has the advantages that the integral structure of the distal humeral outer plate is in an anatomic form design, the rod component made of long steel plates can be rearwards twisted below deltoid tuberosity, the tail of the rod component further extends to the proximal humeri, accordingly, the deltoid tuberosity can be effectively avoided, deltoid dead points do not need to be peeled off in surgical procedures, soft tissues can be protected, the surgical operation difficulty can be lowered, and the surgical time can be saved; the distal humeral outer plate can be used with a distal humeral inner plate, the distal humeral outer plate and the distal humeral inner plate can be fixed by the aid of parallel plates, arch crown structures between internaland external columns can be formed, and arch crown sample stabilization mechanisms can be formed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel distal humerus lateral bone plate. Background technique [0002] The human humeral shaft is in the shape of a cylinder as a whole, and the distal end is divided into the medial and lateral branches of the humerus, which look like a flat and wide fan. There is an angle of forward tilt with the axis of the humerus, and the condyle of the humerus is thin, so fractures are prone to occur (such as Figure 1-1). Distal humerus fracture is one of the common fractures of the elbow. In recent years, with the increase of traffic accidents and the aging of society, the incidence rate is on the rise. Fractures of the distal humerus mainly include supracondylar, intercondylar, small head and simple fractures involving the medial and medial condyles, etc. This part has anatomical particularity and complexity. In addition, due to osteoporosis, comminution of the joint and metaph...

AI Technical Summary

Problems solved by technology

[0004] For existing double plate fixation methods (such as Figure 1-3 and Figure 1-4 ), there will be a blind area no matter whether vertical or parallel boards are used (such as Figure 1-2 As shown, areas A and B are blind areas, where A area is the trochlear joint, and B area is the small head of the humerus). Although the vertical plate can fix the pulley, the screws on the outer plate cannot cross the pulley and hit the inner lower corner of the pulley bottom of

However, the parallel plate screws cannot reach the small head of the humerus, and the main body of the outer plate is placed behind the distal end of the humerus, so it does not play the role of pushing the pulley from the outside during fixation, so it cannot cooperate with the inner plate to clamp the pulley at the same time effect
