- See:
Trans-scaphoid Perilunar Dislocation:
- Discussion:
- occurs as
oblique frx thru radial styloid, extending thru scapholunate
ligament and around the lunate, thru the triquetral attachments;
- due to the
radiocapitate ligament, the fractured styloid process migrates
with the distal carpal row;
- because styloid is held by radiolunate and radioscaphoid
ligaments,
reduction is usually possible, but proximal displacement w/ scaphoid is common;
- Treatment:
- screw fixation of the styloid may be required;
- repair of the scapholunate ligament is recommended to avoid
SLD;
