Rigid Immobilization for Displaced Fractures
We suggest rigid immobilization in preference to removable splints when using non-operative treatment for the management of displaced distal radius fractures.

Rationale
For the purposes of this recommendation we considered rigid immobilization to be any form of immobilization that was firm (e.g. plaster, fiberglass) and not intended for self-removal, and less-rigid immobilization was any type of wrap or brace that either incompletely immobilized the wrist or was intended to be removed by the patient.  

Five Level II randomized controlled trials met the inclusion criteria.47-51  There were significant differences in pain at 5-6, 8 and 24 weeks in favor of casting. All other durations of follow-up did not have significant differences between patients treated with rigid immobilization or less-rigid immobilization. Radial nerve symptoms occurred more often in patients treated with less-rigid immobilization and no other complications were significantly different.
