Closing radial wedge osteotomy for Preiser's combined with Kienbock's disease: two case reports

Avascular necrosis involving more than one carpal bone is rare, and the appropriate treatment for this condition has not yet been established. In this report, two patients with concomitant Preiser's and Kienböck's disease who also had severe wrist pain without obvious traumas were treated by closing radial wedge osteotomy (CRWO). Clinical evaluation showed that CRWO was effective against both conditions and indicated that it is more suitable for early stage than stage II diseases of the Hebert and Lichtman classifications.
