✨ TUESDAY TIP: Neonatal Hip Ultrasound ✨
Normal Graf Alpha & Beta Angles

Before measuring, make sure you have an optimal standard coronal image:

✓ Straight iliac wing
✓ Sharp acetabular promontory
✓ Femoral head at its widest diameter
✓ Labrum clearly visible

📐 Baseline: Place the baseline along the straight lateral edge of the iliac wing.

🔵 Alpha angle: Evaluates the bony acetabular roof.
Normal: α ≥ 60°

🟡 Beta angle: Evaluates the cartilaginous roof and labrum.
Common normal target: β < 55°

💎 Clinical Pearl: Optimize first and measure second. Never force angles onto a suboptimal image—accurate measurements begin with the correct imaging plane.

🔍 The Overlooked A2 Pulley

Finger pain and stiffness aren’t always caused by an A1 pulley problem.

This week’s case features a rower presenting with finger pain and stiffness. Ultrasound demonstrated focal hypoechoic thickening of the A2 pulley surrounding the flexor tendons at the level of the proximal phalanx.

Watch this week’s Reel to learn what to look for, how to measure and compare the pulley, and why dynamic ultrasound is so important.

Measure it. Compare it. And most importantly—watch it move.

🚨 That “ganglion cyst” on the back of the wrist may not be a ganglion cyst at all…

Could it actually be a carpal boss? 🤔

This is one of the most common pitfalls I see when scanning the dorsal wrist. The ultrasound findings can look very different once you know exactly what to look for—and one simple technique can make all the difference.

🎥 In this week’s Tuesday Tips with Jamie, I cover:
✅ How to distinguish a carpal boss from a ganglion cyst
✅ The ultrasound features that separate the two
✅ The most common scanning mistake
✅ A simple anatomical trick to improve your diagnostic confidence
✅ Ultrasound and X-ray correlation

If you perform MSK ultrasound—or you’re learning wrist anatomy—you won’t want to miss this one.

🔍 Tuesday Tips with Jamie

Empty Cubital Tunnel? Where Did the Ulnar Nerve Go? 🤔

Have you ever scanned the cubital tunnel and couldn’t find the ulnar nerve behind the medial epicondyle?

Before assuming something is wrong, always ask about a history of ulnar nerve transposition. Surgical history completely changes where you should be looking. After transposition, the ulnar nerve is moved anterior to the medial epicondyle, and dynamic MSK ultrasound allows us to evaluate not only the nerve’s appearance but also how well it glides in its new location.

During your examination, look for:
✅ Smooth nerve gliding
✅ Stable anterior position without
compression or instability
✅ Preserved fascicular pattern

Be alert for:
🔴 Restricted movement
🔴 The nerve appearing stuck within
postoperative scar tissue, limiting its
normal movement
🔴 Kinking or recurrent compression
🔴 Enlargement or loss of the normal
fascicular pattern

🎥 I put together a quick Reel demonstrating these concepts and what to look for during a dynamic examination.

🦴 Tuesday Tips with Jamie | What Is an Enthesophyte?

Have you ever noticed a bright bony projection at a tendon attachment while scanning and wondered what you were seeing?

One common answer is an enthesophyte—a chronic bony outgrowth that develops where a tendon or ligament attaches to bone.

Recognizing enthesophytes on ultrasound is an important skill because they can easily be mistaken for other abnormalities if you’re unfamiliar with their appearance.

In today’s quick educational reel, I review:
✔️ What an enthesophyte is
✔️ Its characteristic ultrasound appearance
✔️ How to differentiate it from osteophyte and calcific tendinitis
✔️ A few scanning pearls to help build confidence during your MSK exams

Don’t Miss the Fluid Hiding in the Recesses 🦵💧

Most missed knee effusions aren’t absent… they’re just not where you looked.

Fluid moves freely throughout the joint — so if you’re only checking the suprapatellar recess, you’re leaving blind spots.

⸻

🔍 What we’re covering in this video:
• Medial & lateral parapatellar recesses
• Short + long axis views
• Where fluid loves to hide

⸻

📌 Key Takeaways:
• Fluid is mobile — position matters
• Don’t stop at the suprapatellar recess
• Always check medial + lateral recesses
• Use short AND long axis
• Mild flexion helps redistribute fluid

🎯 Complete scan = fewer missed effusions

⸻

🧠 Quick Scan Protocol:
• Suprapatellar recess — short & long axis
• Lateral parapatellar recess — short & long axis
• Medial parapatellar recess — short & long axis

👉 Assess with the knee in mild flexion

👉 Add Power Doppler:
• Evaluate synovium for hyperemia
• Increased Doppler signal → suggests active synovitis
• Helps differentiate simple effusion vs inflammatory process
