Chronic recurrent volar dislocation of the distal radioulnar joint is
a rare condition for which many operative procedures have been described.
We describe a case of painful dislocation on supination. Investigation
of the distal radioulnar joint revealed the absence of degenerative arthritis
and a flat sigmoid notch that permitted dislocation. The case was successfully
treated by osteoplasty of the volar lip of the sigmoid notch to create
a buttress that prevented volar dislocation.
