The patient’s right clavicle is more prominent than the left clavicle, the following reasons should be considered: First, both the right clavicle has been traumatized: for example, a clavicle fracture occurred, during the healing of the clavicle fracture, the formation of bone scabs will occur at the fracture site, and local bone growth may occur, so it may appear that the right clavicle is larger and more prominent than the left clavicle. Second, right acromioclavicular joint dislocation: Consider the right acromioclavicular joint dislocation caused by trauma. When the traumatic right shoulder lands, it is very easy to cause the rupture of the acromioclavicular ligament and rostral ligament, which will cause the distal end of the right clavicle to protrude upward, which can be shown as the distal end of the right clavicle is higher than the left clavicle.
