Avascular Necrosis of Capitate and Other Uncommon Presentations of Carpal Avascular Necrosis.

Outside of Preiser and Kienbock disease, avascular necrosis (AVN) of the remaining carpal bones is a rare cause of wrist pain and disability with a natural history that is incompletely understood. At present, much of the available clinical information exists in the form of isolated case reports or small case series. Although reported surgical treatment options are numerous, there is a dearth of comparative studies and long-term outcomes data with which to guide management.
