Thumb Sprain

Definition
– Any stretch or tear to the ligaments that support the thumb. There are 4 main ligaments that support the thumb, 2 at the distal joint and 2 at the proximal joint. These ligaments are referred to as the ulnar collateral and radial collateral ligaments.

Method Of Injury
– At the proximal joint, injury to the ulnar collateral ligament is referred to as a Skier’s thumb injury
- A complete tear of the UCL of the proximal joint is also known as a Stener Lesion
- Radial collateral ligament injury at the proximal joint is less common but may occur due to a fall on the hand, or a severe rupture of the ulnar collateral ligament
- Ulnar collateral sprain of the distal joint occurs from a sideways force
- Radial collateral sprain of the distal joint occurs from a sideways force

Treatment
– Initially all sprains of the thumb should be treated with the PIER principle (Pressure, Ice, Elevation, Rest)
- X-ray should be taken to rule out any avulsion fracture
- Surgery is necessary if a Stener lesion is present
- RCL injuries of the proximal joint are casted for 6 weeks
- Physiotherapy/Athletic therapy should be done to strengthen joint and surrounding muscles
- Brace/supported for return to activity
