What is DeQuervain’s?
DeQuervain’s is a condition that effects the tendons on the thumb side of the wrist causing pain.
DeQuervain’s will often become apparent due to pain and swelling over the thumb side of the wrist. The pain will sometimes travel down into the thumb or up into the forearm.
The pain of DeQuervain’s is due to a thickening of the sheath, which causes a tightening over or compression of the tendons, and sometimes swelling in the area. This makes movement of the tendon painful.
Signs and symptoms of DeQuervain’s
It is associated with movement of the wrist or thumb. You will normally notice the pain when you lift up a baby, reach out to grab something with an open thumb or lift the thumb up and down repeatedly. You can also notice pain in positions where your wrist is bent forward and towards the little finger side of your hand. Side-to-side movement of the wrist is another common movement that will cause symptoms. The pain will be even worse if you are holding something heavy or doing something requiring force
What causes DeQuervain’s?
DeQuervain’s is very common in new parents. This is due to holding and lifting a new baby with the thumbs up, combined with an up-and-down movement at the wrist and holding their baby on their hip for sustained periods. DeQuervain’s is also common in work that requires strong or repetitive thumb and wrist movements. Direct trauma such as falling on your wrist or thumb, a sudden twisting force in the area or a direct blow to the side of the wrist can also cause DeQuervain’s.
Treatment for DeQuervain’s
- Splinting. Your physiotherapist or hand therapist will make you a splint to greatly reduce the movement of the thumb tendons. This splint will need to hold the wrist and part of the thumb still, but you will still be able to do everything you need to do with the splint on. The splint will be required for up to six weeks.
- Education on activity modification. Simple adjustments to your activities can be very helpful, like changing the wrist and thumb position you use when you’re lifting things or avoiding static holding positions of the thumb and wrist that are painful. There are many things a physiotherapist can show you that will reduce the pain.
- Exercises. Rehabilitation exercises of the thumb tendons will help reduce the pain and also strengthen the area. Regular exercises are known to be a vital part of treatment and are important to help prevent a recurrence of the condition. Generalised strengthening of the shoulders and elbows can also place less load at your wrist, helping long-term recovery.
- Massage and other soft tissue techniques. Soft tissue techniques to relax the muscles may be incorporated into treatment sessions with your physiotherapist to help reduce the tension in the muscle/tendon unit. This can help the other treatments outlined here.
