Collateral ligaments at the wrist
Ligaments are strong ‘elastic bands’ that attach a bone to a bone to stabilise a joint. The collateral ligaments at the wrist lie on either side of the wrist and act as a restraint to sideways movements. The ligaments can be sprained by suddenly overstretching the joint, as in falling onto the hand. Or they may become painful with repetitive overuse in occupational activities or hobbies. The patient will complain of a specific point of tenderness on one side of the wrist and stretching the ligament into the opposite direction will also be painful.
Physiotherapy can help by applying a specific massage technique called frictions across the tender point on the ligament. Ice and electrotherapy may also be used with advice to avoid aggravating activities, if possible, until the pain settles. An injection of steroid may be given if the symptoms persist.
