Systematic checklist approach to the evaluation of wrist radiographs ensures detection of common and uncommon diagnoses.
Evaluation of the carpal arcs helps to detect subtle cases of carpal dislocations.
Understanding the concept of carpal arcs of injuries enables the radiologist to detect the combination of injuries that is common in wrist trauma.
1. Common radiographic views
2. Osseous anatomy
3. Checklist
a. White cortical line outlining all bones
b. PA view
1. Joints: radiocarpal, distal radioulnar, and carpometacarpal
2. Carpal arcs are smooth and concave
3. Contour of ulna parallels contour of radius
4. Cortical rim of hook of hamate
5. Ulnar variance: positive, negative
c. Lateral view
1. Metacarpals alignment
2. Capitate, lunate and radius align
3. Contour of ulna parallels contour of radius
d. Soft tissue assessment
1. Fat stripes: scaphoid, pronator quadratus
2. Mass
4. Concept of carpal arcs of injuries
5. Cases
a. Carpal coalitions
b. Ulnar variance
c. Fractures
d. Dislocations
1. Carpal: RSS, DISI, VISI, perilunate, midcarpal, lunate
2. Carpometacarpal joint
3. Distal radioulnar joint
e. Soft tissue
1. Abnormal fat stripe
2. Ganglionic cyst
3. Tenosynovitis
4. Neoplasms
