Neer’s method is divided into 3 types: Type I: Microdisplacement. The fracture is located between the rostral-clavicular ligament and the acromioclavicular ligament, or between the tapered ligament and the rhomboid ligament. The ligament remains intact without damage, and the fracture end is stable and not significantly displaced. Type II: Displaced type. The fracture occurs medial to the rostral collateral ligament, thus allowing upward displacement of the medial fracture segment. Type III: Intra-articular type. The fracture includes the lateral articular surface of the clavicle. Rockwood typing: Type I: The acromioclavicular ligament is stretched, but the clavicle periosteum is not torn. The patient has only localized pressure pain in the acromioclavicular joint and there are no changes in the acromioclavicular joint on imaging. Type II: The periosteum is partially torn, and the affected clavicular space is slightly wider than the healthy side on imaging. The acromioclavicular space is significantly widened. Type III: severe dorsal tear of the periosteum, with the clavicle equivalent to the scapula displaced upward. The clavicle is markedly elevated and the scapula is subluxated. This finding is often clinically confirmed. The affected side of the clavicular space is significantly increased compared to the healthy side. The acromioclavicular joint and distal clavicle are swollen and ecchymotic. If there is no widening of the clavicular space and the acromioclavicular space is significantly widened, the clinician should have a high suspicion of a rostral basilar fracture. This injury is where the rostral styloid fracture occurs prior to the periosteal tear. A rostral tuberosity fracture can be diagnosed by axial axial phase of the axilla, but preferably by Stryker cut axis. Type IV: The clavicle is displaced posteriorly relative to the acromion. In fact, the clavicle is not displaced due to a strong middle clavicular connection, it is the scaphoid that is displaced forward. There is no significant increase in the clavicular space, which can lead the clinician to mistakenly believe that there is no significant injury. Palpation of the distal clavicle in relation to the acromion and axial axial images of the axilla can reveal a backward displacement of the clavicle. Our knowledge of the disease is only to better keep away from its damage, and if we fully grasp the typology of clavicle fracture, we can well determine our disease and thus find the right treatment for our condition.
