==Background==
*Reverse Bennett: fracture of fifth metacarpal base, with extensor carpi ulnaris traction on distal metacarpal while proximal fragment still algined with carpals
**See [[Thumb fracture]] for Bennett fracture

==Clinical Features==
*Movement at the wrist elicits pain
*Assess for ulnar deficits (finger abduction/adduction)
*Assess for rotational alignment

==Differential Diagnosis==
{{Hand and finger fractures DDX}}

==Evaluation==
*Xray hand: AP, lateral, oblique
*30 deg obliques pronated and supinated if usual films unable to visualize the MC bases
*Consider CT if index of suspicion high for occult fracture despite "negative" plain films

==Management==
*Dorsal and [[Forearm Volar Splint‎]] with the wrist in 30 deg of extension and MCP joints free

==Disposition==
*Refer for:
**Intraarticular fracture
**Extraarticular fracture with malrotation
**Dislocation of metacarpal base CMC joint;
**Ulnar nerve injury
**5th metacarpal base fracture (typically require surgery)
