Musculoskeletal ultrasound

Ultrasound diagnostics is the most frequently used imaging method in medicine.
In orthopaedics, ultrasound is mainly used to examine the locomotor organs, in particular muscles, bursa, tendons, ganglia and joints.

The examination is painless and completely harmless compared to an X-ray. For this reason, we not only use ultrasound for children, but also primarily for injuries prior to an X-ray for diagnostic purposes.
Ultrasound can also be more sensitive than an X-ray:
Do you see a fatigue fracture on these x-rays of an 18-year-old athlete?

No? The fatigue fracture is almost invisible on the x-ray.

But it is clearly visible on the ultrasound images

Some fractures or bone chips are also invisible on x-ray, for example, if they are oriented in the direction of the x-ray beam.
Invisible, "occult" tarsal fracture on X-ray

Ultrasound is also the examination method of choice for tendon injuries such as this complete Achilles tendon rupture

... and often easier and faster to obtain than an expensive magnetic resonance tomography, which also impressively shows the Achilles tendon tear.

In addition, for certain treatments we also use ultrasound to determine the position of cannulae or to locate and focus calcific foci during fragmentation by means of shockwaves.

The visualisation of the spinal canal with the spinal cord can only be achieved with ultrasound in rare cases, as in this postoperative case.
