Distal radioulnar joint disruption
Revision as of 15:48, 22 March 2016 by Ostermayer (talk | contribs) (Text replacement - "Category:Ortho" to "Category:Orthopedics")
Background
- Seen w/ intra-articular or distal radial shaft fractures or both bone fracture
Imaging
- PA
- Narrowing and overlap of distal radioulnar joint
- Lateral
- Volar or dorsal displacement of ulna (which is usually centered/overlapping the radius)
- Requires a true lateral to avoid a false positive result
Differential Diagnosis
Distal radius fractures
- Colles' fracture
- Smith's fracture
- Barton's fracture
- Radial styloid fracture
- Distal radioulnar joint disruption
Distal radius fracture eponyms
Eponyms | Description |
Barton's | Fracture-dislocation of radiocarpal joint (with intra-articular fracture involving the volar or dorsal lip) |
Chauffer's | Fracture of radial styloid |
Colles' | Dorsally displaced, extra-articular fracture |
Die-punch | Depressed fracture of the lunate fossa (articular surface) |
Smith's | Volar displaced, extra-articular fracture |
Management
- Dorsal dislocation
- Immobilize wrist in supination
- Volar dislocation
- Immobilize wrist in pronation
