Volar Barton's Fracture Wheeless

Description: characterized by fracture of volar margin of the carpal surface of the radius which is associated w/ subluxation of radiocarpal joint;
- similar to Smith's type III;
- comminuted fracture of distal radius may involve either anterior or posterior cortex and may extend into the wrist joint;
- both involve volar dislocation of carpus assoc w/ intra articular distal radius component;
- fracture dislocation or subluxation in which the rim of distal radius, dorsally or volarly is displaced with the hand and carpus;
- it differs from Colles' or Smith's Fracture in that the dislocation is the most striking radiographic finding
