Resolution
The x-ray shows a Bennett’s fracture dislocation.
As noted in Wheeless’ Textbook of Orthopaedics (www.wheelessonline.com), this fracture dislocation is an intra-articular fracture occurring at the base of the carpometacarpal joint of the thumb.
Patients who experience this most common of all thumb fractures should be referred to hospital for reduction and management by orthopedist.
