Scapular glenoid fracture closed reduction hollow screw fixing guide apparatus

Abstract

The invention relates to a scapular glenoid fracture closed reduction hollow screw fixing guide apparatus. The scapular glenoid fracture closed reduction hollow screw fixing guide apparatus is characterized by comprising a foundation base, wherein the foundation base is in a plate-shaped structure, and at least one screw guide hole group is arranged on the foundation base; the screw guide hole group comprises first base points positioned on the lower surface of the foundation base and a plurality of second base points positioned on the upper surface of the foundation base and arranged at intervals, the second base points are respectively connected to the first base points, so that the through holes communicating the upper and lower surfaces of the foundation base are formed, the included angle alpha of the axis of each through hole and the crown-shaped face is 32-52 degrees, and the included angle between the axis of each through hole and the sagittal plane is 53-73 degrees. According to the scapular glenoid fracture closed reduction hollow screw fixing guide apparatus, the human anatomy statistical data is taken as the basis, so that the abundant trauma caused by large-area stripping is avoided; through the arrangement of the screw guide hole groups, the scapular glenoid fracture closed reduction hollow screw fixing guide apparatus can adapt to patients with different body forms, the operation of preparing one guide apparatus for each patient independently is not needed, therefore, the use is convenient, and the achievement ratio of the operation is high.

Description

technical field [0001] The invention relates to a medical device, in particular to a hollow screw fixation guide for closed reduction of glenoid fracture. Background technique [0002] The incidence of scapula fractures is low, accounting for about 3-5% of shoulder fractures and 0.4-1% of systemic fractures. But its function is important in the shoulder, which is an important structure connecting the trunk and upper limbs. If not handled properly, it can often cause disability of the patient's shoulder. For a long time, there has been controversy in the treatment of scapula fractures, mainly because the anatomy and function of the scapula are complex, and there are many theories about the mechanism of its participation in shoulder activities. There is still no relatively complete fracture classification system that can guide treatment and predict outcomes. . In terms of treatment, the determination of surgery and non-surgical treatment is more based on personal experience...
