どう骨遠位骨端線損傷の合併損傷の臨床的検討

Abstract

Twenty-eight patients with injuries associated with physeal injury of the distal radius were reviewed radiologically and clinically. Fracture of the ulnar styloid process was found in twenty cases, fracture of the distal ulna in seven, and physeal injury of the distal ulna in one. Fracture of the distal ulna was united in all cases, but fracture of the ulnar styloid process was united in only five of fourteen cases which were followed from four months to nine years. However, none of the cases with non-union of the ulnar styloid process were symptomatic. We emphasize that fracture of the ulnar stybid process often does not unite, and must be followed for a long time.
