We are experienced in testing the different types of problems that can cause your finger pain. Our specialists use a variety of tendon gliding techniques to determine the extent of the damage. The core of the assessment involves testing of the tendon’s ability to move & slide. We develop a certain dexterity to detect a pulley problem.
If your test results prove that we suspect that you may have another problem relating to the tendon, we will require further investigation. The first on the list will be a Sonar.
X-rays will be an unnecessary test, as the bones are still normal, and the joints are not influenced. So X-rays will be redundant in this case.
This is a very useful tool to see in detail the extent of the damage, but any skilled hand therapist will be able to diagnose a trigger finger without an expensive MRI.
Sonar (Diagnostic Ultrasound):
A sonar can determine the thickness, and degree of swelling of the tendon. Even better, the sonographer will be able to show you a live video that shows the thickened part of the tendon as it is unable to glide through the pulley. This is called a functional sonar.
