The Green and O'Brien classification of thumb metacarpal fractures is a commonly used classification system when assessing thumb metacarpal fracture s.

However, since most types of fractures coincide with well-known eponymous fractures, the system itself is not usually used properly, giving preference to naming the types as the eponymous fractures themselves.

Classification

type I: simple intra-articular (Bennett fracture)
type II: comminuted intra-articular (Rolando fracture)
type III: extra-articular, epibasal (pseudo-Bennett fracture)
- IIIA: transverse
- IIIB: oblique
type IV: epiphyseal fracture
