Sigmoid notch osseous reconstruction.
The purpose of this article is to describe a technique of restoring stability or congruency to the distal radioulnar joint (DRUJ) by osteoplasty or osteotomy of the sigmoid notch, where abnormalities in the osseous anatomy have resulted in DRUJ instability. This technique addresses the osseous cause to DRUJ instability and avoids the need for complex soft tissue procedures to treat chronic volar instability or salvage procedures to treat dorsal instability of the DRUJ associated with an impacted fracture of the dorsal rim of the sigmoid notch.
