Clinical type bone plate for distal humeral fracture

Abstract

The invention relates to a clinical type bone plate for distal humeral fracture. The clinical type bone plate for the distal humeral fracture comprises a handle-shaped first supporting plate and a square second supporting plate, wherein the width of the main body of the first supporting plate is greater than the width of the main body of the second supporting plate; one end of the first supporting plate, far away from the second supporting plate, is provided with an arc-shaped end part; one end of the second supporting plate, far away from the first supporting plate, is provided with an end part which inclines upwards slightly and takes a linear shape roughly; the left end part of the second supporting plate connected with the first supporting plate takes an arc shape which is roughly square; the left edge part of the connecting part of the second supporting plate and the first supporting plate takes an arc shape and slightly inclines towards the central part of the main body of the second supporting plate; the right edge part of the connecting part of the second supporting plate and the first supporting plate takes a concave arc shape and is connected with the upper edge of the second supporting plate; in the main body of the first supporting plate, a plurality of fixed bolt through holes are formed at the roughly central position in the width direction along the length direction; and in the main body of the second supporting plate, two rows of fixed bolt through holes are distributed roughly uniformly along the width direction.

Description

technical field [0001] The invention relates to a clinical bone plate for distal humerus fracture. It belongs to the technical field of medical equipment. Background technique [0002] At present, in the surgical treatment of humeral medial condyle fractures at home and abroad, in the selection of internal fixators, due to the irregular anatomical contour of the humeral medial condyle and the large curvature of the metaphyseal transformation zone, it is difficult for various steel plates to accurately shape and fracture. There is no relevant morphological and anatomical description, and there is no internal fixation that meets the anatomical characteristics, which greatly reduces the surgical effect. The ideal fixation method should not only protect the biological environment of fracture healing, but also provide a sufficiently stable mechanical environment for fracture healing. Therefore, the development of internal implants suitable for internal fixation of humeral condyl...

AI Technical Summary

Problems solved by technology

[0003] At present, lateral anatomical plates, chain plates, Y-shaped plates, etc. are used to treat medial humeral condyle fractures through open reduction and internal fixation through various surgical approaches. Even through intraoperative shaping, the internal fixation cannot conform to the posterior side of the ankle The surface characteristics (hollow nails are only suitable for single, non-comminuted and collapsed fracture fragments) affect the effect of surgery and treatment

However, after the steel plate is bent, its strength and firmness both decrease, and the long-term efficacy is still inconclusive. The comparison of biomechanics between different internal fixation methods still needs further research and confirmation.
