Learn MSK Sono

Reposting an interesting MSK ultrasound case from my colleague (and co-director of our upcoming course) 👇

This is exactly the kind of real-world, case-based learning we focus on—understanding pathology, thinking through the diagnosis, and applying it directly in clinical practice.

Our upcoming course is officially sold out 🙌
Thank you to everyone who signed up—really looking forward to it.

If you’re interested in attending a future course, send me a message with your email . I’ll make sure you’re the first to hear when new courses open.

Small group. Big skills. 💪🖥️

See it. Follow it. Question it. 👀

The superficial peroneal nerve is small and easy to overlook—but when it becomes enlarged at the point where it exits the crural fascia, it’s often a sign of entrapment.

📍 Where to find it:
• Between the peroneus longus and extensor digitorum longus
• Distal lateral leg as it becomes more superficial
• Pierces the crural fascia (anterior to the fibula)
• Becomes subcutaneous just above the ankle

⚠️ Important:
Entrapment often occurs right where the nerve pierces the fascia and transitions to a superficial location.

In this case:
• Focal enlargement at the fascial exit
• Clear caliber change on long axis
• Increased cross-sectional area

⚠️ Symptoms can be subtle:
• Burning or tingling along the lateral lower leg
• Dorsal foot paresthesia
• Worse with activity
• Often no motor deficit

➡️ Easy to mistake for tendon or lateral ankle pathology

🎥 Watch the video to see how this looks on ultrasound.

Pro tip:
Use a cine loop and follow the nerve dynamically—this is where you’ll catch subtle abnormalities.

👉 Follow the nerve
👉 Compare sides

If it catches your eye… there’s usually a reason.

👶 🦴 Did you know pediatric MSK ultrasound looks very different from adult imaging?

One commonly misunderstood finding is the immature epiphysis.

I made a quick video explaining the ultrasound appearance and why it’s important to recognize.

Pediatric MSK Ultrasound Tip 👶

When imaging children with MSK ultrasound, understanding normal skeletal development is essential.

Pediatric anatomy looks very different from adults, and recognizing these differences helps prevent misdiagnosis.

🦴 Immature Epiphysis

In children, the epiphysis (the rounded end of a long bone) is largely composed of cartilage before it fully ossifies.

🔍 Key concepts:

• The epiphysis is covered by articular cartilage

• Early in development, epiphyseal cartilage is continuous with joint cartilage

• Vascular supply within the cartilage helps support bone formation (ossification)

🖥 Ultrasound appearance:

Because the epiphysis is mostly cartilage, children often show larger hypoechoic cartilage regions on ultrasound compared with adults.

🧠 Takeaway: Always consider skeletal maturity when interpreting pediatric MSK ultrasound.

💬 Question:

In the skeletally immature patient, the Achilles tendon inserts onto which type of ossification center of the calcaneus?

Have you ever had to evaluate the on and didn’t know where to start?

The pectoralis is not part of a standard shoulder ultrasound protocol, so there are not a lot of resources out there on how to scan it.

Do you know which deformity presents as a hard on the ?

The answer is: Haglund’s deformity

Haglund’s deformity is a prominence that forms at the insertion onto the posterosuperior aspect of the .

The patient may present with the following symptoms:

🔹 Palpable lump on the back of the heel
🔹Skin discoloration in area of lump
🔹 Heel pain
🔹 Posterior ankle swelling

On ultrasound, the lump will appear as multiple growths of bone extending outwards from the surface of the posterosuperior calcaneus. This is called exostosis. The Achilles tendon should also be scanned in the long and short axis and power should be utilized to document and hyperemia present within the tendon or surrounding bursae,

Associated ultrasound findings may include:

🔹An underlying calcaneus spur
🔹 Achilles tendinosis and/ or tears
🔹Retrocalcaneal and/ or superficial calcaneal
bursitis
