Ultrasound of the Achilles tendon – You can see that!
In the case of an Achilles tendon inflammation, different findings can be observed depending on the severity of the inflammation. It is important to compare both Achilles tendons with each other during the ultrasound examination. Thus, possibly degenerative processes, which are caused by a long-term strain, can be distinguished from acute inflammatory processes.
Normally, the Achilles tendon has a diameter of about half a centimeter. This can be enlarged in the event of inflammation. Especially in chronic Achilles tendon inflammation, the Achilles tendon thickens.
In addition, structural changes can be observed in ultrasound. If, for example, tissue breakdown occurs in the Achilles tendon during a long-lasting inflammation, the tendon is usually less echo-proof and appears darker in the ultrasound. If, on the other hand, calcification and firmer tissue remodelling occur, the Achilles tendon appears lighter to whitish in ultrasound.
A Doppler ultrasound examination can even be used to assess the blood supply to the Achilles tendon. In cases of severe chronic changes, a particularly pronounced new formation of vessels can be observed. Acute Achilles tendon inflammation, on the other hand, often reveals a rather swollen Achilles tendon. This is caused by the many inflammatory cells that are transported to the acute site of inflammation.
MRI of the Achilles tendon
Treadmill analysis is used in the diagnosis of Achilles tendonitis, primarily to identify the cause of the symptoms. For example, malpositions of the ankle joint during walking can be recorded. The treadmill analysis is also used in the therapy of Achilles tendonitis.
Here, the progress of the treatment can be recorded so that, for example, the improvement of an incorrect sequence of movements can be seen. Treadmill analysis plays an important role in the prophylaxis of Achilles tendonitis, especially when buying jogging shoes.
