The main reasons for slightly elevated acromion after clavicle fracture surgery are related to displacement of fracture, failure of surgical repositioning or bone abnormality. 1. Displaced fracture: If the clavicle fracture is treated by surgery, if the affected side of the upper limb is moved too soon after the surgery, or if the fracture is displaced due to local impact, the slightly elevated acromion may be triggered. 2. Failure of surgical repositioning: If the clavicle fracture is treated by surgery, but the fracture is not well aligned during the surgery, resulting in failure of repositioning, the fracture will lead to a slightly elevated acromion after the surgery, and at the same time, it may lead to obvious symptoms of pain and swelling. 3. Skeletal abnormality: If the clavicle has abnormal morphology and structure, it is easy to produce a slightly upturned acromion, so this kind of problem will occur after clavicle fracture surgery, but it will not affect the range of motion of the local joints in general. If the symptom is serious and affects the range of motion of the shoulder joint, it is necessary to go to the orthopedic department to take pictures for review, and under the guidance of professional doctors, to prevent the sequelae of motor dysfunction in the later stage.
