How effective is fracture casting for distal radius fracture?

The distal radius is the end of the forearm bone next to the wrist. A cast supports the wrist and forearm, limiting movement while the fracture knits. It may work well when the pieces can be positioned and kept in a useful relationship. A fracture that involves the wrist joint, is significantly displaced, or shifts after casting may need a different approach.

Swelling often changes during early healing. A splint may be used first, followed by a cast when the fit is safer. Follow-up examination and imaging help the clinician check that the wrist position is being maintained. Stiffness, reduced grip and weakness can persist after immobilisation and are addressed gradually.

Rest the arm on pillows when swelling rises, keep the cast dry, and move the fingers and elbow if those movements are permitted. Avoid lifting, pushing or using the injured hand for support. Keep review appointments, since a cast that becomes loose may no longer support the wrist properly. Later exercises should follow the plan given by your clinician.

Seek urgent assessment if fingers become cold, blue, pale, numb or hard to move, or if swelling and pain keep increasing. Arrange prompt review for a wet, broken, tight or rubbing cast, or for a new loss of finger movement. Severe pain out of proportion to the injury needs immediate attention.

Ask whether the fracture enters the wrist joint, how stable its position is, when you can use the hand, and when repeat images are needed. Ask which finger exercises are safe and how stiffness will be managed after the cast is removed.
