- Anatomy:
- radius & ulna lie parallel to each other when forearm is supinated;
- during pronation radius crosses ulna, rotating on axis that passes from capitulum through the distal end of ulna;
- ular side of wrist is supported by
TFCC, which articulates w/ both lunate and
triquetrium;
- ulnar attachment of
TFC is to base of
ulnar styloid & distally to triquetrum w/ volar ulnocarpal
ligaments;
-
interosseous membrane:
- radius and ulna are joined by proximal & distal
RU joints & by interosseous membrane, which is directed obliquely downward from radius to ulna;
- since ulna does not articulate w/ carpi, direction of interosseous membrane is important in transmission of longitudinal forces from radius to ulna;

Distal Ulnar Physeal Fractures:
- Radiographs:
- in the child, it is essential to have 3 views of the elbow: (AP, lateral, and oblique) before a
Monteggia frx can be ruled out;
- this is especially true in proximal ulnar shaft frx;
