Estabilización dinámica radiocubital distal para eltratamiento de la rotura del complejofibrocartílagotriangular asociada a fractura de extremidad distal deradio–una nueva técnica quirúrgica

Abstract

Distal radioulnar instability secondary to rupture of the triangularfibrocartilagecomplex (FCT) produced in fractures of the distal radius is one of the most difficultcomplications to treat in our specialty. Early functional recovery of postoperative radiusfracture requires early mobilization and consequently it can result in a poor FCThealing. On the other hand, the correct treatment of this rupture, regardless of thetreatment performed (conservative, open or arthroscopic repair), requires animmobilization of the wrist and elbow for a period of not less than 6–8weeks.Thisfact may compromise the functional result of both the radius surgery and theradioulnar movement. We describe thefirst surgical technique in the literature thatallows a correct healing of the FCT, at the same time that mobilization wrist begins inthefirst week of the postoperative period, both the radiocarpal and distal radioulnarjoint. It is a surgery to be performed immediately after radio synthesis procedure. It is asimple technique and low morbidity, which stabilizes the distal radioulnar joint in adynamic way, so that the direction of rotation where the instability is reproduced isrestricted, stabilizing dorsopalmar translation movement and joint opening
