Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic steel plates, in particular to an acromion anatomical locking steel plate. Background Art

[0002] The acromion is a part of the cantilever arm that extends forward from the scapular spine. The acromion is only protected by the scapular spine and the surrounding muscle tissue. Since the tissue above the acromion is weak, it is easy to fracture the acromion when it is impacted. Acromion fracture is a special type of scapula fracture, accounting for about 9% of scapula fractures. Acromion fractures are mostly caused by a strong direct violent blow or a strong upward impact of the humerus. A locking plate is used in the surgical treatment of acromion fractures.

[0003] The existing locking plate for acromion fracture has an integrally formed acromion fixing portion and a scapular spine fixing portion. However, when the locking plate is installed on the acromion, due to the angle between each person's acromion and scapular spine, the traditional integrally formed locking plate cannot perform micro-adjustment of the angle between the acromion fixing portion and the scapular spine fixing portion during installation, resulting in low installation adaptability of the locking plate.
