We undertook a prospective, single blinded, randomized, controlled trial of one hundred children treated with either an above or below elbow cast for treatment of closed, distal third forearm fractures requiring reduction. The re-manipulation rate in the below elbow group was 2% (95%CI: 0–11%) compared to 6% (95%CI: 2–15%) in the above elbow group, p=0.62. Above elbow casts do not appear to improve fracture immobilization nor reduce the requirement for re-manipulation in pediatric distal third forearm fractures.

Debate exists regarding the benefits of using below elbow casts instead of above elbow casts for maintaining reduction in pediatric distal third forearm fractures. The literature indicates a loss of reduction rate of 14.6% of children treated in an above elbow cast and 2.5% in those treated with a below elbow cast.

We undertook a prospective, single blinded, randomized, controlled trial of one hundred children treated with either an above or below elbow cast for treatment of closed, distal third forearm fractures requiring reduction. Outcome measures included re-manipulation rate, fracture displacement during cast wear, and cast complications. One hundred patients were suitably enrolled; fifty-four received an above elbow cast, forty-six received a below elbow cast. The two groups were similar in terms of age and gender. The above elbow group contained a higher proportion of both bone fractures (41/54) than the below elbow group (27/46).

There were no significant differences between the two cast groups in initial, post-reduction or cast-off fracture angulation; nor any difference in the amount of fracture displacement during cast wear. The number of cast complications was similar between the two groups. The re-manipulation rate in the below elbow group was 2% (95%CI: 0–11%) compared to 6% (95%CI: 2–15%) in the above elbow group, p=0.62.

Above elbow casts do not appear to improve fracture immobilization nor reduce the requirement for re-manipulation in pediatric distal third forearm fractures.
