Problems solved by technology

After the actual operation, a small number of patients are prone to redisplacement of fracture fragments, failure of fixation and complication caused by varus of the humeral head
At the same time, during the lifting of the shoulder joint, the protruding part or the proximal end of the steel plate is likely to collide with the acromion and cause pain, which limits the range of motion of the patient's upper limbs.

Embodiment Construction

[0009] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0010] In the description, the accompanying drawings and the claims, unless explicitly stated, the end close to the acromion of the scapula is referred to as the "proximal end", and the end far away from the acromion of the scapula is referred to as the "distal end". The proximal humerus mainly includes the hemispherical humeral head, the greater tuberosity, and the lesser tuberosity. There is also an anatomical neck between the greater and lesser tuberosities and the hu...

Abstract

The invention discloses a wing type anatomical plate for the proximal humerus. The anatomical plate comprises a transition zone and a far-end zone. A near-end portion of the moving region comprises a left wing portion extending towards the upper left direction and a right wing portion extending towards the upper right direction. A concave portion is formed between the left wing portion and the right wing portion. According to the wing type anatomical plate, the concave portion is arranged, so that impacting of the shoulder joint against acromia in an uplifting process is prevented, and pains of patients are reduced. A fracture block is firmly wrapped in the plate through triangular fixation formed by the left and right wing portions and the far-end region, and re-displacement cannot occur. Simultaneously, the left and right wing portions are thin, so that a good bending property is provided, and rebuilding of humeral neck stem angles is facilitated.

Description

technical field [0001] The invention relates to a proximal humerus wing-type anatomical steel plate, which belongs to the field of anatomical steel plates. Background technique [0002] Proximal humerus fracture is one of the more common fractures, accounting for about 4% to 5% of systemic fractures. Especially for patients with comminuted fractures or osteoporosis, effective fixation can provide early functional exercise of the shoulder joint. There are many methods used. From the perspective of the strength of the fixation, the fixation of the steel plate is more reliable. Generally, a spoon-shaped, trefoil or locking plate is used for treatment. However, among the existing proximal humerus anatomical plates, some have a protruding part in the proximal part, and some can only be fixed laterally and adjacent to the greater tuberosity. It forms a linear fixation with the main body of the steel plate, and the left and right directions are not fixed. After the actual operat...
