Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] Proximal humeral fractures are fractures above the base of the greater tuberosity (surgical neck). Avulsion fractures and humeral head fractures are more common in middle-aged and elderly people, which are related to osteoporosis; comminuted humeral head fractures are more common in middle-aged adults; surgical neck fractures are more common in children, followed by slipped epiphysis. Proximal humeral fractures account for 4% to 5% of all fractures in the body and 45% of humeral fractures, of which 80% to 85% are non-displaced or slightly displaced fractures, and 15% to 20% are displaced fractures. Women have a higher incidence rate, twice that of men. The vast majority of proximal humerus fractures can be treated conservatively, and only about 15% of severely displaced or comminuted fractures require surgical treatment. According to the characterist...

Abstract

The invention relates to a shoulder joint dynamic and static combined regulation external fixator, comprising a bone external fixation support, a steel needle fixation clamp connected to the bone external fixation support, and a steel needle clamped in the steel needle fixation clamp, wherein the bone external fixation support comprises a near end hole C-shaped ring and a far end hole C-shaped ring, and the opening directions of the near end hole C-shaped ring and the far end hole C-shaped ring are the same, the near end hole C-shaped ring and the far end hole C-shaped ring are uniformly provided with a plurality of holes, the middle parts of the near end hole C-shaped ring and the far end hole C-shaped ring are connected by an arc-shaped connecting rod, the two ends of the near end hole C-shaped ring and the far end hole C-shaped ring are connected by dynamic traction joint devices, each dynamic traction joint device comprises a first joint connecting piece connected with the hole at the end part of the near end hole C-shaped ring and a second joint connecting piece connected with the corresponding hole in the far end hole C-shaped ring, and the first joint connecting piece and the second joint connecting piece are connected by a central spindle and can swing relative to the central spindle. The fixator is flexible in operation, the curative effect is improved, and the complications of proximal humeral fracture of shoulder joints are reduced.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to an external fixator for treating shoulder joint fractures. Background technique [0002] In the existing medical technology, when the patient has a proximal humeral fracture of the shoulder joint, plaster splint is usually used for fixation, but such fixation for a long time will cause the deltoid muscle, biceps brachii brachii, long head of triceps brachii, beak The brachialis causes shortening deformity, the strength of the rotator cuff teres minor and the supraspinatus and inferior muscles is greater than that of the subscapularis, causing a slight external rotation of the proximal end, and there is no muscle attachment on the medial side of the humeral head. End outreach. In addition, because the blood supply of the humeral head comes from the tuberosity, a fracture of the humeral head can easily cause avascular necrosis of the humeral head. [0003] Therefore, it is necessar...
