A fastening steel plate for internal fixation of an acromioclavicular joint dislocation, comprising an anchoring steel plate (1) at a distal end of a collarbone and a fastening steel plate (2) at a distal end of a shoulder blade ridge. Two to five anchoring screw holes are provided at a proximal end of the anchoring steel plate (1) and two to five recess screw holes (4) are provided at a distal end, a spherical recess (5) is provided at the middle of the recess screw hole (4). Two to five fastening screw holes (6) are provided at a proximal end of the fastening steel plate (2), and two to four fastening slanting pin holes (7) are provided at a distal end. A gradually thickening and narrowing arch arm (8) is disposed at a distal end side of the fastening steel plate (2), and a fastening ball (9) is disposed at the distal end of the arch arm (8). The fastening steel plate specially used for internal fixation of the acromioclavicular joint dislocation is configured to have a ball and socket joint shape, for fixing dislocation of the acromioclavicular joint as well as accommodating small multi-plane movements of the acromioclavicular joint, thus meeting the needs of acromioclavicular joint movement. |
