| 1. Middle 1/3 Clavicle Fracture | |
| 2. Lateral 1/3 Clavicle Fracture Divided into five subtypes based on the degree of fracture and coracoclavicular ligament injury: |
I Type: Occurs on the lateral side of the coracoclavicular ligament, as the coracoclavicular ligament remains connected to the clavicle, maintaining its position, this type often has no displacement |
| II Type: Occurs on the medial side of the coracoclavicular ligament, the proximal fracture segment loses traction fixation and easily displaces upward, while the weight of the upper limb and muscle traction cause the distal fracture segment to move downward | |
| III Type: Fracture of the lateral end including the acromioclavicular joint surface, this type of fracture almost always heals but can easily cause acromioclavicular joint degenerative arthritis | |
| IV Type: In children, the coracoclavicular ligament is connected to the periosteum and the proximal segment of the fracture displaces | |
| V Type: Comminuted fracture, the coracoclavicular ligament attachment fracture is separated from the proximal and distal fracture segments | |
| 3. Medial 1/3 Clavicle Fracture | |
