Isolated volar distal radioulnar joint (DRUJ) dislocation is a rare type of traumatic joint dislocation and is rarely seen even by orthopaedic specialists. Surgical intervention is often not warranted, as closed reduction followed by immobilisation is often successful. This is the case of an 88-year-old woman who presented with pain in the right forearm after a fall. The diagnosis of a volar DRUJ dislocation was confirmed by radiographic imaging and treated by closed reduction. After immobilisation in a long-arm cast for three weeks and a forearm splint for another two weeks, full functionality of the hand and wrist was eventually gained after six months. The triangular fibrocartilage complex (TFCC) usually provides sufficient stability and healing to stabilise the DRUJ.
