Diagnosis of Scaphoid Fracture Displacement
Which of the following statements describes bestthe diagnosis or prognosis of scaphoid fractures?
a. CT as opposed to radiographs improves sensitivitybut not specificity of scaphoid fractures.
b. CT as opposed to radiographs improves specificitybut not sensitivity of scaphoid fractures.
c. Radiographic displacement and classification cor-relate with union rate.
d. Fractures displaced less than 2 mm on CT are lesslikely to unite.
e. CT scan can predict the likelihood of scaphoid
A 0.5-mm scaphoid fracture gap:
a. Can be accurately assessed with radiographs.
b. Cannot be diagnosed by CT scan.
c. Should be considered a nondisplaced fracture.
d. Can be more accurately assessed by CT thanradiographs.
e. Should only be diagnosed by arthroscopy becauseit is the reference standard.
