Sprains [Wrist]
Overview
When this type of injury occurs, and a patient sustains a wrist sprain, the ligaments of the wrist are stretched beyond their normal limits. A ligament is made of tough, fibrous tissue that holds the bones together around a joint. The ligaments around the wrist joint help to stabilize the position of the hand and allow controlled motions.
Classification
As they differ from person to person, wrist sprains are graded according to the severity of the injury:
- Grade I: Mild injury, the ligaments are stretched, but no significant tearing has occurred.
- Grade II: Moderate injury, the ligaments may be partially torn.
- Grade III: Severe wrist sprain, the ligaments are completely torn, and there may be instability of the joint.
