Arm, shoulder and hand injuries

DeQuervain's Syndrome

What is the DeQuervain's syndrome?

DeQuervain's syndrome is when the two tendons that move your thumb become thickened. These two tendons lie together in a small compartment in the outer part of your thumb, just below your wrist.

The changes are due to excessive thumb and wrist movement which creates friction, irritation and swelling of the tendons and their supporting sheath. It is usually associated with repetitive activity.

It is also common after having a baby when new forces through your thumb and wrist occur with lifting your baby.

What may I experience?

  • Localised tenderness
  • Swelling at the base of  your thumb
  • Difficulty with gripping, lifting and/or pinching
  • Irritation/ hypersensitivity of radial nerve

To help better assess your injury, fill in the DASH questionnaire.

What should I do?

You need to wear a custom made splint to rest the tendons for three to six weeks. Occasionally, the splint needs to be worn for up to three months.  You will learn about how to alter the activites that produced the pain.

You will also need to look at ways to temporarily rest your hand. Usually, three to six weeks of therapy is required to aide in the reduction of pain, educate you in ways to alter activities which aggravate the injury and provide you with stretching and strengthening exercises. You will also be given a home program to follow.

What can I expect?

Recovery time is dependent on the severity of the injury and the activities of the patient. In most cases, after wearing a splint for three weeks, pain should be significantly reduced. Sometimes a splint is required for up to three months.

Because DeQuervains is a mechanical injury it is essential that there is a change in the way certain activities are performed. The activity that aggravated the condition must not be continued to be carried out in the same way. If the therapists instructions are ahedered to, you can expect to remain pain free once treated.

Dislocations of the thumb and fingers are common. Dislocations occur when a large force, usually hyperextension, pushes the bone out of its normal joint position.

Wrist Instability

Wrist instability occurs when one or more of the wrist ligaments have lost integrity, are lax, or damaged. This alters the normal wrist mechanics of the carpal bones and hence affects your hand function.

Triangulo-fibro Cartilage Complex

Your triangulo-fibro cartilage complex (TFCC) is a structure that sits as a sling to hold the outside of your wrist together.
