title: [Dislocation of the Ulnar Head following Malunion of Distal Radius Fracture in Childhood].
abstract: Four children between the age of 10 and 13 years with distal radius fractures healed with dorsal angulation presented to us in our out-patient department. All had been treated conservatively with an upper-arm cast, all fractures had healed with an average dorsal angulation of 10 degrees. Despite this dorsal angulation, the patients were pain free. Subsequent minor injury resulting in pain to the wrist was now the reason for their presentation. On examination we found a spontaneous palmar dislocation of the ulnar head during supination. This proved to be resistant to conservative therapy. In all cases corrective osteotomy of the radius at the level of angulation was performed. Redislocation of the ulnar head was prevented by this method in all cases.
