– Discussion: – characterized by frx 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 frx of distal radius may involve either anterior or posterior cortex and … Read more
– See: Carpal Instability – Discussion: – by definition, consists of volar flexion of the lunate relative to the longitudinal axis of the radius and capitate, when the wrist rests in a neutral position; – lunate will tend to flex when there is loss of ulnar support from the triquetrum; … Read more
