– Discussion: – is most common distal fracture; – intact ligaments hold frag together & prevent rotation, tilting, sig displacment; – this is an interligament frx which occurrs between conoid & trapezoid or CC & AC ligs
– Discussion: (see: dynamic instability); – type of non dissociative carpal instability; – capitolunate joint has high potential for instability, since it is mainly stabilized only by radiocapitate ligament (and captiotriquetral ligament, to a lesser degree); (see wrist ligaments); – may result from malreduced radial styloid frx, or any … Read more
