15+ years of pain. One precise diagnosis.

For years, she was told her lateral hip pain was simply “bursitis.”

A detailed examination and diagnostic MSK ultrasound revealed the actual pathology: severe gluteus medius and gluteus minimus tendinosis.

Now we have a target.

This is the TenJet procedure, performed under real-time MSK ultrasound guidance to precisely target the pathologic tendon tissue.

Diagnose precisely. Treat precisely.

Elite athletes require precision.

This college athlete presented with a persistent re**us femoris injury that had not responded as expected.

Using diagnostic MSK ultrasound, I was able to precisely localize the pathology to the mid-muscle belly of the re**us femoris, with no involvement of the musculotendinous junction.

Once the pathology was confirmed, I used the same real-time ultrasound guidance to precisely target the abnormal tissue with high-concentration, double-spin PRP.

Diagnose precisely. Target precisely. Treat precisely.

MSK ultrasound is more than imaging—it is an integral part of the treatment process.

15+ years of lateral hip pain — and the pathology was finally identified with ultrasound.

A complete history, physical examination, and dynamic MSK ultrasound revealed severe gluteus medius and gluteus minimus tendinosis.

This is why I don’t believe in simply treating the area that hurts. Identify the structure. Confirm the pathology. Then build the treatment plan.

Diagnostic MSK ultrasound allows us to see the pathology in real time and correlate it directly with the patient’s clinical presentation.

Don’t just treat the pain. Diagnose the pathology.

This 40-year-old, highly active hairstylist had been dealing with persistent upper back/periscapular pain for 5 years.

She tried to live with it, but for someone who uses her upper body all day, every day, it was miserable.

Using diagnostic MSK ultrasound, we were able to identify the abnormal fascia and myofascial tissues involving the trapezius and rhomboid region.

At her previous visit, we performed a targeted ultrasound-guided anesthetic injection to confirm that we were treating the right pain generator. The result supported our diagnosis.

Today, we targeted those same areas with high-volume, double-spin PRP under ultrasound guidance.

This is where MSK ultrasound becomes more than just imaging.

See it. Confirm it. Target it.

This 68-year-old long-distance runner had been unable to run for several months because of persistent lateral hip pain.

She had never had an ultrasound evaluation of the gluteal tendons. Using diagnostic MSK ultrasound, we identified the areas of gluteal tendon pathology and were able to target the abnormal tendon directly.

We proceeded with high-concentration, double-spin PRP (LR Platelet-Rich Plasma) to the areas of tendinosis—at her very first visit.

We don’t treat the age of the patient. We treat the patient in front of us, and build the plan around their goals.

For her, the goal isn’t simply to “feel better.” It’s to get back to running marathons.

This is expert-level, ultrasound-guided treatment of gluteal tendinopathy. With the pathology identified under high-resolution musculoskeletal ultrasound, I’m able to precisely target and debride the diseased portions of the gluteus medius and gluteus minimus tendons with TenJet and dynamic ultrasound.

For patients with chronic lateral hip pain caused by gluteal tendinopathy, this is one of the most advanced minimally invasive treatment options available. No blind treatment. No guessing. See it. Target it. Treat it.

This 30-year-old patient presented with a 2-year history of persistent mid-back myofascial pain despite extensive conservative treatment.

When conventional approaches have been exhausted, I believe the next step is not simply another injection—it is a more precise evaluation of the pain generator.

Using high-resolution musculoskeletal ultrasound, I evaluated the symptomatic fascial and myofascial structures dynamically and in real time, identifying the areas most consistent with her pain.

We then proceeded with an ultrasound-guided fascial injection, allowing precise treatment of the targeted tissue under direct visualization.

This is where advanced MSK ultrasound can make a significant difference:
identify the pain generator → precisely target the abnormal tissue → treat under real-time ultrasound guidance.

Her symptoms improved immediately following the procedure.

At Mississippi Motion, we use MSK ultrasound not simply to guide a needle, but as a diagnostic tool to identify and treat musculoskeletal and fascial pain with precision.

Four structures. One comprehensive ultrasound evaluation. One treatment session.

I first used diagnostic ultrasound to identify the pathology in the quadriceps tendon, patellar tendon, pes anserinus, and IT band—then immediately transitioned to ultrasound-guided TenJet treatment of each affected structure.

This is the advantage of combining advanced musculoskeletal ultrasound with minimally invasive tendon treatment: see the pathology, target the pathology, treat the pathology.

The gluteal tendons were successfully treated one week prior.

At Mississippi Motion, we treat the root cause.

Before the TenJet procedure, we verify the pathological tendon(s) with a detailed exam and MSK ultrasound evaluation.

Quadriceps tendon insertion.
Patellar tendon origin and insertion.
Pes anserinus insertion.
IT band insertion.

The technology is cutting-edge.
The diagnosis is exact.

Pain at the base of the thumb can make lifting a child, opening a jar, gripping a golf club, or simply texting miserable.

In this case, I performed a focused physical exam, confirmed the diagnosis with musculoskeletal ultrasound, and delivered a precise ultrasound-guided injection directly to the inflamed tendon sheath.

Why ultrasound guidance? Confirms the diagnosis. Improves accuracy. Avoids nearby nerves and vessels. Allows treatment exactly where it’s needed.

If you’ve had thumb-side wrist pain that won’t go away, don’t ignore it—getting the correct diagnosis is the first step toward getting pain free.
