R. Nakamura et al., ULNAR STYLOID MALUNION WITH DISLOCATION OF THE DISTAL RADIOULNAR JOINT, Journal of hand surgery. British volume, 23B(2), 1998, pp. 173-175
Four patients with dorsal dislocation of the distal radioulnar joint a
nd ulnar styloid malunion had corrective osteotomy of the ulnar styloi
d, Dislocation of the distal radioulnar joint was reduced in three of
four patients, Subluxation persisted in the remaining patient. Wrist f
unction improved in all patients. These results support the contention
that a displaced ulnar styloid fracture with distal radioulnar joint
dislocation should be reduced and internally fixed. Corrective osteoto
my is recommended for malunion of the ulnar styloid associated with di
slocation of the distal radioulnar joint.
