Description
Technical field
The present invention relates to medical instruments field, particularly relate to coronoid process of ulna mixed lateral column steel plate.
Background technology
Posterior Elbow Dislocation, coronoid process fracture, fracture of head of radius are called as terrified triad, and coronoid process has important function in stablizing on front side of maintenance elbow joint, but up to the present, after coronoid process fracture, which kind of therapeutic modality is best, on the knees of the gods.
The analysis being familiar with coronoid process fracture is most important to treatment treatment, three types are divided into according to the height of coronoid process sclerite on the X-ray film of position, side: 1 type fracture involves coronion in the Regan-Morrey typing extensively adopted at present, II type fracture involves 50% or following of coronoid process height, and III type fracture exceedes 50% of coronoid process height.O ' Driscoll in 2003 etc. are on the basis of Regan-Morrey typing, add coronoid process anteromedial surface classification of fracture, according to the region of anatomy, coronoid process fracture is divided into three types: I type is coronion fracture, II type is coronoid process anteromedial surface fracture, III type is coronoid process basilar part fracture, and every type fracture is divided into different subtype according to the order of severity of fracture again.Although this typing based on CT is comparatively detailed, too loaded down with trivial details, clinically should not to apply.
We are by proximal ulna specimen observation substantially, two obvious bone ridge protuberances on front side of visible coronoid process of ulna, distally extended by near-end before the articular surface of coronoid process of ulna medial and lateral respectively, form 2 three-dimensional column structures, we are defined as coronoid process " inside and outside lateral column ".Wherein mixed lateral column is distally extended by front lateral articular face (coronalplane outer 1/2), be positioned at the inner side of head of radius incisura, corresponding front lateral articular face, with trochlea of humerus associated section, its feature is: coronion is positioned at mixed lateral column, articular surface comparatively columnae medialis higher, tilt backwards, the gradient of post is larger, but short.Damage is common in the dislocation of the elbow joint, and damage mechanisms is often for supination outward turning causes.
Different coronoid process classification of fracture, its Therapeutic Method is obviously different, steel plate is the conventional medical apparatus in fractures, current for coronary dash forward fracture steel plate special few, as: the patent No. is that the Chinese utility model patent " crown shaped projection pressing steel board for ulnar " of ZL200920254783.0 (Authorization Notice No. is CN 201533867 U) discloses a kind of medical steel plate, this steel plate comprises steel plate main body, the both sides of this steel plate main body are respectively provided with a saddle flank, one end of this steel plate main body is provided with two table fork shape projections, this projection is tilted to top upward by root, the top of this projection is provided with a rebate, the below of this rebate is provided with anti-skidding thorn.And for example: the Chinese invention patent " a kind of Olecroanon locking bone fracture plate " that the Chinese invention patent " tension side-fixing bone plate for olecranon process of ulna " that the patent No. is ZL200810079748.X (Authorization Notice No. is CN1014064408 B), application number are 201010104343.4 (application publication number is CN 101773407 A).
Because the anatomical features in lateral articular face is unique, be not exclusively used in the steel plate of coronoid process lateral articular facial bone folding at present, i.e. coronoid process mixed lateral column fracture steel plate, therefore studies coronoid process of ulna mixed lateral column steel plate further, for the therapeutic strategy of clinical formulation mixed lateral column fracture is significant.
