A sprained thumb is an injury to a ligament of the thumb. A ligament is a soft tissue that connects bones to help stabilize joints. The most injured ligament in the thumb is the ulnar collateral ligament. This ligament helps connect the thumb to the hand towards the index finger.
Our team at OrthoNeuro can help you accurately diagnose whether or not you have a sprained thumb due to a recent injury. Give us a call today for a diagnosis and a personalized treatment plan for you.
Signs of sprained thumb may include:
A jammed thumb may also have similar symptoms. However, most people with a jammed thumb can still use and move their thumb.
These symptoms may also be synonymous with a fractured or broken thumb, so it is important to go to a physician to determine the specific injury and whether or not it is a severe sprain.
A sprained thumb is common with sports injuries or falls, especially when the thumb is bent in an awkward and extreme position.
Ligaments can withstand a small amount of stretching, but when they have overstretched, this results in a partial or complete tear of the ligament. One or more ligaments may be affected by the thumb.
“Skiers Thumb” is a common sprained thumb ligament injury amongst skiers. This occurs when skiers fall and land on their hand/pole, tearing the ulnar collateral ligament.
To diagnose, your provider will complete a thorough medical history. They also may:
Immediately after injuring the thumb, follow P.R.I.C.E. – protection, rest, icing, compression, elevation, until you can see your provider. The sooner you see a provider, the better your recovery will be. Waiting too long to see a provider may result in permanent damage to the thumb.
Non-surgical treatments include immobilizing the thumb joint with a cast, bandage, and splint until it heals. Ice packs can aid in easing pain or swelling.
Surgical treatments may be indicated if the ligament is completely torn or if there is an associated avulsion fracture. Avulsion fractures occur when the torn ligament pulls fragments of the bone away with it. After surgery, typically, the thumb will then be cast to heal.
Remember, every patient and sprain is different. Make sure to speak with a hand surgeon to determine the best treatment option for you.
Recovery differs from patient to patient but typically can range from 6-12 weeks until total recovery from the point of treatment. Physical therapy is usually necessary after either non-surgical or surgical treatment to re-strengthen the thumb.
Athletes should have a pain-free full range of motion, total recovery of strength, and functional ability of the thumb before returning to their respective sport. Athletes may also wear protective splinting or taping when they return to sport, especially if the injury is severe.
Whether returning to work or a sport, please make sure to be cleared by your provider before doing so.
