DeQuervain’s Tenosynovitis is an overuse injury that causes inflammation and pain of the tendons at the base of the thumb. This can happen to anyone, but is most common in females. It is often associated with a mother carrying a new born baby. It is also common with activities such as computer, videogame use, and texting.
DeQuervain’s tenosynovitis is caused when the tunnel for the tendons at the base of the thumb, also known as the 1st Dorsal compartment, becomes inflamed from injury, overuse, or repetitive activity.
DeQuervain’s tenosynovitis is diagnosed in the office after thorough discussion and physical exam with your orthopedic provider. X-rays are usually taken to rule out arthritis at the base of the thumb.
Surgery for DeQuervain’s tenosynovitis is a successful, minimally invasive procedure. It involves a small incision over the 1st Dorsal Compartment Tendon Sheath. The tendon sheath is then cut to release pressure off the thumb tendons.
In most cases, you can begin moving and using the hand immediately after surgery. Heavy lifting should be avoided for at least 2-4 weeks. Hand therapy is sometimes recommended to improve range of motion of the hand and fingers.
