I am having surgery to repair a torn ligament in my wrist. The doctor is going to put my whole arm in a cast for six weeks. Is this really necessary for a small tear in the wrist?
Treating wrist injuries can be very difficult. Early and careful treatment is important. The choice of treatment depends on the location and severity of the injury. A long arm cast is usually used to avoid stress to the repaired ligament. The doctor will place your forearm in a specific position (sometimes with the hand facing up or facing down), depending on the location of the tear.
Four to six weeks is about how long it takes for soft tissues to heal with enough strength to withstand the forces of everyday movement. Don't be surprised by any stiffness in your wrist and forearm when the cast comes off. Usually, a short course of physical therapy with range of motion and strengthening exercises will help you get back to normal.
