Diaphyseal simple, spiral clavicle fracture

The AO/OTA classification does not further subdivide simple fractures of the diaphysis into subtypes (spiral, oblique, or transverse), but the treatment may vary depending of the fracture configuration.

They are all classified as AO/OTA 15.2A fractures.

Definition: The diaphysis of the clavicle extends from the attachment of the coracoclavicular ligament laterally to the costoclavicular ligament medially.
