title: Rheumatoid synovitis of the volar compartment of the wrist joint: its radiological signs and its contribution to wrist and hand deformity.
abstract: The radiological signs that suggest involvement of the volar compartments of the wrist include grooving of the scaphoid, pseudocysts of the distal radius, and scaphoid-lunate dissociation. These indicate involvement of the radiocarpal ligamentous support. This leads to loss of stability of the scaphoid, which then goes into a volar-flexed position, contributing to shortening the radial carpal height and favoring rotation of the carpus into supination, radial deviation of the metacarpals, and ulnar drift of the fingers.
