Description
Technical field
The present invention relates to medical instruments field, more particularly to coronoid process of ulna mixed lateral column steel plate.
Background technology
Posterior Elbow Dislocation, coronoid process fracture, fracture of head of radius are referred to as terrified triad, and coronoid process is maintaining elbow joint
Front side stabilization aspect plays an important roll, but up to the present, which kind of therapeutic modality is optimal after coronoid process fracture, on the knees of the gods.
It is familiar with the analysis of the coronoid process fracture Regan-Morrey parting most important, widely used at present to treatment treatment
The middle height according to coronoid process sclerite on the X-ray film of side position is classified as three types：1 type fracture involves coronion, II type fracture
Involve 50% or less of coronoid process height, III type fracture is more than the 50% of coronoid process height.O ' Driscoll in 2003 etc. exist
On the basis of Regan-Morrey partings, coronoid process anteromedial surface classification of fracture is increased, according to the region of anatomy by coronoid process bone
It is three types to split：I type is fractured for coronion, and II type is fractured for coronoid process anteromedial surface, and III type is fractured for coronoid process basal part,
Per type, fracture is divided into different subtype according to the order of severity of fracture again.Although this parting for being based on CT is more detailed, excessively
It is cumbersome, clinical unsuitable popularization and application.
We are observed by substantially proximal ulna sample, it is seen that the obvious bone ridge protuberance in coronoid process of ulna front side two, point
Do not extended by proximate from before the articular surface of coronoid process of ulna medial and lateral, form 2 column structures of solid, Wo Mending
Justice is coronoid process " inside and outside lateral column ".Wherein mixed lateral column is extended from preceding lateral articular face (coronal-plane outer 1/2) to distal end, positioned at oar
The inner side of bone incisura, corresponding preceding lateral articular face, with trochlea humeri associated section, its feature is：Coronion is located at outside
Post, articular surface is higher compared with columnae medialis, tilt backwards, and the gradient of post is bigger, but short.Damage is common in the dislocation of the elbow joint, is damaged
Mechanism is often for supination outward turning causes.
Different coronoid process classification of fracture, its treatment method is significantly different, and steel plate is the conventional Medical treatment device in fractures
Tool, the steel plate special currently for coronoid process fracture is few, such as：(Authorization Notice No. is Patent No. ZL200920254783.0
CN 201533867U) Chinese utility model patent《Crown shaped projection pressing steel board for ulnar》A kind of medical steel plate is disclosed, the steel plate
Including steel plate main body, the both sides of the steel plate main body are respectively provided with a saddle flank, and one end of the steel plate main body is provided with two table forks
Shape projection, the projection is inclined upward by root to top, and the top of the projection is provided with a rebate, the lower section of the rebate
It is provided with anti-skidding thorn.And for example：The middle promulgated by the State Council of Patent No. ZL200810079748.X (Authorization Notice No. is the B of CN 1014064408)
Bright patent《Tension side-fixing bone plate for olecranon process of ulna》, (application publication number is CN to Application No. 201010104343.4
101773407 A) Chinese invention patent《A kind of Olecroanon locking bone fracture plate》.
Because the anatomical features in lateral articular face is unique, currently without the steel for being exclusively used in coronoid process lateral articular facial bone folding
Plate, i.e. coronoid process mixed lateral column fracture steel plate, therefore further research coronoid process of ulna mixed lateral column steel plate, are clinical formulation mixed lateral column
The therapeutic strategy of fracture is significant.
