Study summary

The purpose of this study is to determine whether a sugar-tong splint is as effective as a long-arm cast in maintaining reduction of pediatric forearm shaft fractures in a randomized, prospective manner. Consented participants will be randomly assigned to be treated with either a sugar-tong splint or a long-arm cast (both standard of care treatments) in REDCap. Each participant will have a 50/50 chance of being assign to either treatment.

Read the detailed description

Forearm fractures are very common in the pediatric population and can often be treated with closed reduction and immobilization. Immobilization techniques include long-arm casting, short-arm casting and sugar-tong splinting. At the time of injury casts are usually split into two using a cast saw, known as bivalving, to allow for swelling and are overwrapped at a later time. By design sugar-tong splints allow for swelling and are overwrapped or converted to a cast at a later time. Traditionally long-arm casts have been used as the standard mode of immobilization for forearm fractures. Recent evidence demonstrates that long-arm casting is equivalent to better tolerated short-arm casting as an immobilization choice for distal third forearm fractures.1 Further work has shown that sugar-tong splints are also appropriate for treatment of distal third forearm fractures. No study has compared the efficacy of using a long-arm cast versus a sugar-tong splint for treatment of forearm shaft fractures.

Interventions

  • DeviceLong-Arm Cast

    A long-arm cast is a circumferential wrapping of the arm from the fingers to above the elbow with casting material.

  • DeviceSugar-Tong Splint

    A sugar-tong splint is the application of hard splinting material on the front and back of the arm.
