Below-Elbow Versus Initial Above-Elbow Casting for Distal Radius Fractures

The goal of this clinical trial was to compare two casting strategies for adults with a broken wrist, also called a distal radius fracture. The study included people whose treating team had determined that treatment without surgery was appropriate. Their fracture was first put back into position without surgery. The main questions were: * Does starting treatment with a below-elbow cast or an above-elbow cast affect how well the fracture stays in position? * Does cast length affect early elbow or shoulder pain and stiffness? * Does it affect grip strength, arm and wrist muscle recovery, wrist function, or long-term disability? Researchers compared a below-elbow cast used from the start with an above-elbow cast used for the first 2 weeks and then changed to a below-elbow cast. Participants: * were randomly assigned to one of the two casting strategies * wore a cast for 4 weeks, followed by a splint and rehabilitation * had x-rays and clinical assessments during the first 12 weeks * were scheduled for bilateral grip-strength and machine-based muscle-strength testing at cast removal and at 12 weeks * were invited to complete a clinical and functional follow-up assessment at approximately 5 years
