Spiral bone plate for use on outer side of proximally middle section of humerus

Abstract

The invention discloses a spiral bone plate for use on the outer side of the proximally middle section of a humerus. The head part of a plate body is provided with a plate-shaped part(1), and the tail part is a strip-shaped part(2); and a plurality of connecting holes(3) are distributed on the plate-shaped part(1), a plurality of fixed holes(4) are distributed on the strip-shaped part(2), the plate-shaped part(1) is wider than the strip-shaped part(2), and a spiral part(5) used for transition between the plate-shaped part(1) and the strip-shaped part(2) is arranged between the plate-shaped part(1) and the strip-shaped part(2). The bone plate has the advantages of narrowing a stripping range of a dead point of the deltoid muscle, reducing the influences of the long head tendon of the biceps brachii, avoiding affecting the slide of the tendon, reducing operative wound and operation time and facilitating the functional rehabilitation after the operation.

Description

technical field [0001] The invention relates to a helical bone plate on the outside of the proximal and middle section of the humerus. Background technique [0002] Fractures of the proximal and middle segments of the humerus are common types of fractures, 15% of which require open reduction and internal fixation. Bone plate internal fixation is a relatively common internal fixation method. It is usually placed on the lateral side of the humeral head and neck shaft, and the operation is generally performed through the deltoid-pectoralis major muscle space approach, but the insertion point of the deltoid muscle located on the lateral side of the middle and upper 1 / 3 of the humerus limits the placement of the distal end of the bone plate on the lateral side of the humerus, and usually The best way to deal with it is to peel off the humerus shaft muscle of the deltoid muscle, especially when the fracture extends to the middle, it often needs more extensive peeling, resulting in...

[0002] Fractures of the proximal and middle segments of the humerus are common types of fractures, 15% of which require open reduction and internal fixation. Bone plate internal fixation is a relatively common internal fixation method. It is usually placed on the lateral side of the humeral head and neck shaft, and the operation is generally performed through the deltoid-pectoralis major muscle space approach, but the insertion point of the deltoid muscle located on the lateral side of the middle and upper 1 / 3 of the humerus limits the placement of the distal end of the bone plate on the lateral side of the humerus, and usually The best way to deal with it is to peel off the humerus shaft muscle of the deltoid muscle, especially when the fracture extends to the middle, it often needs more extensive peeling, resulting in severe damage to the dynamic tendon of the shoulder joint (deltoid muscle), which not only aggravates the surgical trauma, but also prolongs the fracture. It shortens the operation time and affects the recovery of postoperative function
