Radiology of the Hand and Wrist
- Carpal height & Carpal height ratio
- Distal Radius Fracture
- Radial Length & Width
- Scapholunate Dislocation
- Scaphoid Fracture
- Types of Radiographs:
- Arthrography of the Wrist
- AP View
- Carpal Tunnel View
- Clenched Fist PA
- Lateral View
- PA View
- Pronated Olblique - demonstrates adequately STT joint;
- Reverse Oblique - 15 deg
- Supinated Oblique
- Ulnar Variance
- Zero Rotation Views
- AP View is prefered for Wrist Pathology:
- AP has dorsum of hand touching film, w/ x-ray beam passing palmar to dorsal, whereas in PA film, palmar surface lies flat on film & x-ray beam passes from the dorsal to palmar surface;
- palmar surfaces of most carpal bones are narrower, & these bones are best profiled in AP projection because of the alignment of the peri-articular cortices with the diverging incident x-ray beam;
- position of ulnar styloid will determine which way film was obtained;
- in standard PA view, ulnar styloid is peripheral;
- in standard AP View, ulnar styloid points centrally
