A 33-year-old man sustains blunt trauma to his forearm and presents with the injury seen in Fig A and B. Definitive management of this injury involves the following:
Perform closed reduction of the radius, then immobilize the forearm in a long arm cast in supination.
Perform open reduction and internal fixation of the radius, then assess the proximal radioulnar joint for instability, and percutaneously fix the proximal radioulnar joint if instability persists.
Perform open reduction and internal fixation of the radius, then assess the distal radioulnar joint for instability, and reconstruct the distal radioulnar joint with a looped palmaris longus autograft if instability persists.
Perform closed reduction of the radius, then assess the distal radioulnar joint for instability, and perform internal fixation of the radius if instability persists.
Perform open reduction and internal fixation of the radius, then assess the distal radioulnar joint for instability, and percutaneously fix the distal radioulnar joint if instability persists.

A 42-year-old female sustains the injury shown in Figure A. What other anatomic structure is most commonly injured with this fracture?
Volar long radiolunate ligament
Dorsal radioulnar ligaments
Ligament of Testut and Kuentz
A 30-year-old female presents with the injury shown in Figure A after falling on her outstretched arm. During operative treatment of the fracture, anatomic reduction of the radius is achieved. However, the surgeon is unable to reduce the distal radioulnar joint. What structure is most likely impeding the reduction?
Flexor carpi radialis
Extensor carpi ulnaris
Flexor carpi ulnaris
Which of the following injuries would require plating of the radius along with closed reduction and evaluation of the distal radioulnar joint (DRUJ)?
