title: Treatment of ulnar shaft fractures: a prospective, randomized study.
abstract: The treatment of isolated ulnar shaft fractures is controversial. Previous studies comparing treatment options have been largely retrospective and nonrandomized. In this study, consecutive patients were randomized into treatment groups of long arm plaster immobilization, short arm plaster immobilization, or Ace Wrap bandage, based on the order of hospital admission. Thirty-one patients were followed until radiographic or clinical union, with no significant difference in time to union between groups. Age, sex, fracture pattern, and displacement did not significantly influence time to union or final angulation. Two patients in both the long arm cast group and the short arm cast group lost significant motion at final follow up. Seventy percent of patients in the Ace Wrap group failed treatment secondary to pain and were converted to plaster immobilization. Furthermore, patients in this group demonstrated significantly greater angulation than those treated in a long arm cast. Our results demonstrate that above-elbow plaster immobilization offers no advantage over below-elbow immobilization. We recommend short arm casting for a period of 8 weeks.
