A Musculoskeletal Ultrasound Perspective

Dry needling has become an increasingly common intervention in musculoskeletal rehabilitation and sports medicine. Clinicians frequently use this technique to address myofascial trigger points, tendon pathology, and neuromuscular dysfunction.

However, one important question remains:

What lies beneath the needle?

As clinicians, our understanding of anatomy has traditionally relied on surface landmarks, palpation, and anatomical models. While these tools remain essential, musculoskeletal ultrasound now allows clinicians to visualize anatomy in real time providing a deeper understanding of the tissues we treat.

In recent years, ultrasound has become an increasingly valuable tool in guiding musculoskeletal interventions, including dry needling.

Understanding Dry Needling

Dry needling involves inserting a thin, solid filament needle into muscle or connective tissue structures to influence neuromuscular function and pain. The technique is commonly used to address:

• Myofascial trigger points

• Muscle hypertonicity

• Tendinopathy

• Neuromuscular dysfunction

• Chronic musculoskeletal pain

Unlike acupuncture, which is based on traditional Chinese medicine principles, dry needling is typically applied using anatomical and neurophysiological frameworks.

When performed appropriately, dry needling can be integrated with other rehabilitation strategies such as therapeutic exercise, manual therapy, and motor control training.

The Anatomical Challenge

Many of the muscles targeted in dry needling lie in close proximity to important anatomical structures, including:

• Peripheral nerves

• Major blood vessels

• Pleura and lung tissue

• Joint capsules

• Neurovascular bundles

For example:

Rhomboid region

The pleura and lung are located deep to the intercostal space.

Anterior scalene region

The brachial plexus and subclavian vessels pass between the scalene muscles.

Posterior tibialis

The tibial nerve and posterior tibial artery lie adjacent to the target muscle.

Popliteus

The popliteal artery and tibial nerve lie immediately posterior to the muscle.

These anatomical relationships highlight why a detailed understanding of deep anatomy is critical when performing invasive techniques.

Cadaveric studies examining dry needling procedures have demonstrated that variations in needle length, insertion angle, and anatomical landmarks can significantly affect the accuracy and safety of needle placement.

The Role of Musculoskeletal Ultrasound

Musculoskeletal ultrasound provides clinicians with a real-time view of soft tissue anatomy. Unlike static imaging modalities, ultrasound allows dynamic visualization of muscles, tendons, nerves, and vessels during movement and intervention.

For procedures such as dry needling, ultrasound offers several advantages:

Ultrasound and Clinical Decision Making

It is important to emphasize that ultrasound does not replace clinical reasoning. Instead, it complements a clinician’s understanding of anatomy, biomechanics, and rehabilitation.

This combination of assessment and intervention represents a growing area of musculoskeletal practice often referred to as interventional musculoskeletal ultrasound.

The Future of Musculoskeletal Practice

As musculoskeletal ultrasound continues to expand within physical therapy, sports medicine, and orthopedic practice, its role in diagnostic assessment and procedural guidance will likely continue to grow.

For clinicians interested in advanced musculoskeletal practice, ultrasound offers an opportunity to bridge the gap between anatomical knowledge and real-time visualization.

Ultimately, the goal is not simply to perform procedures but to understand the anatomy beneath the skin.

When clinicians can see what lies beneath the needle, clinical decision making changes.

About Our Courses

At Pura Health, our ultrasound courses focus on helping clinicians develop a deeper understanding of musculoskeletal anatomy using real-time imaging.

Participants learn:

• Musculoskeletal ultrasound fundamentals

• Regional scanning protocols

• Anatomical recognition under ultrasound

• Principles of ultrasound-guided procedures

Through hands-on training and small-group instruction, clinicians gain practical skills that can be integrated directly into clinical practice.
