External fixation system for distal radius fracture

Abstract

Disclosed is an external fixation system for a distal radius fracture. The system comprises an external fixation locking plate, at least four locking sleeves which are matched with the external fixation locking plate, a plurality of metal guide needles which are matched with the locking sleeves and a plurality of hollow screws which are matched with the metal guide needles and the external fixation locking plate. The external fixation system for the distal radius fracture is characterized in that a non-joint integrated type external fixation mode is adopted, the situation is avoided that the joint is not stable in an existing external fixation apparatus; the external fixation locking plate adopts an L-shaped plate type structure to be able to conduct three-dimensional fixation on the two ends of the fracture and improve stability; the direction of the external fixation locking plate and the direction of screw locking holes in the external fixation locking plate are designed according to the anatomical morphology of the distal radius, which is special for the direct fixation of the two ends of the distal radius and different from the indirect fixation of an existing external fixation bracket; the locking sleeves extend a fixed distance in the inner side of the external fixation locking plate, the distance between the external fixation locking plate and the skin of a patient can be limited, and the operation is simpler and more standard; the external fixation system for the distal radius fracture has the effects of internal fixation and external fixation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an external fixation system for distal radius fractures. Background technique [0002] The radius is one of the two bones of the forearm, located on the outside of the forearm, on the side of the thumb. The management of distal radius fractures changed dramatically after Colles' statement in 1814. Although distal radius fractures account for 20 percent of fractures in the emergency room, many people do not get rid of the pain after treatment. The anatomical reduction of the articular surface of the distal radius is the theoretical guide for surgical treatment. Many studies have found that even as little as 1 mm of uneven articular surface can lead to poor outcomes, whereas other studies have reported no association between radiographic arthritis and outcome. [0003] At present, the treatment of distal radius fractures is varied, including non-surgical treatment and su...

AI Technical Summary

Problems solved by technology

Non-surgical treatment is widely used, such as splint or plaster fixation, although the effect is worse than surgical treatment, but the patient acceptance is relatively high, and many patients would rather lose function than accept surgical treatment

Surgical treatment has been widely affirmed, which can be concluded from numerous literature reports: open reduction, plate internal fixation surgery has the best treatment effect, but the acceptance rate of patients with secondary surgery is poor; the second is external fixation bracket , and the non-bridging external fixation method is the best for external fixation brackets, but it is rarely used in China because of the complexity of the fixation method
