The treatment of pulled elbow: a prospective randomized study. 

Taha AM. Arch Orthop Trauma Surg 2000;120(5-6):336-7

To evaluate the effectiveness in decreasing recurrence of cast application after manual reduction of pulled elbow. Sixty-four children with pulled elbow were randomized into two treatment groups: Group A underwent manipulative reduction followed by splinting the elbow in a flexed and supinated position for 2 days; group B underwent manipulative reduction only. Both groups were examined 2, 5, and 10 days later. None of the 33 patients in group A had a pulled elbow at follow-up. Four (13%) of 31 patients in group B had a pulled elbow 2-5 days later. Immobilizing the elbow for 2 days after manipulative reduction improves the success of treatment of a pulled elbow.
