How Doctors Diagnose Jersey Finger: The Imaging Techniques
Published: Sep 14, 2024
Imaging techniques play a crucial role in confirming a jersey finger diagnosis and guiding treatment.
X-ray: The First Step
An X-ray is usually the first imaging test ordered to look for any avulsion fractures associated with jersey finger. It helps identify whether there is a bony fragment at the base of the finger, which can indicate the type of injury. However, X-rays might not show soft tissue damage, so further imaging might be necessary.
MRI: A Detailed View
An MRI provides more detailed images of the soft tissues, revealing the extent of tendon retraction and any associated injuries. It is particularly useful for chronic cases where the injury might not be immediately apparent. MRI is a powerful tool for visualizing the precise location of the tendon rupture.
Ultrasound: A Dynamic Option
Ultrasound can be used to evaluate jersey finger, offering a real-time look at the tendons. This technique is especially useful for identifying partial tears and can sometimes be more accurate than physical examination. It also helps in assessing the tendon's condition after surgery.
