View all RADEOS cases associated with this fact-sheet
Definition
Avascular necrosis of the scaphoid, occurring in the absence of fracture or Non union
Clinical features
Pain on the radial aspect of the wrist, accompanied by stiffness and/or loss of strength
Radiography
Stage I: normal radiographic appearance
Stage II: alterations in density within the scaphoid, predominating at the proximal pole, near the radius; the shape of the scaphoid is preserved.
Stage III: loss of scaphoid shape, sometimes with fragmentation; the proximal portion of the scaphoid is collapsed with an eggshell appearance, indicative of a fracture
Stage IV: marked scaphoid collapse, with signs of radiocarpal Osteoarthritis predominating adjacent to the scaphoid
CT
CT arthrography useful for detecting chondropathy prior to the development of Osteoarthritis
MRI
Defines the extent of necrosis, which is predictive of potential revascularization
Classification
Radiographic (see above)
Differential diagnosis
Non union ++
