From Probe to Practice https://amsku.com Transistor (https://transistor.fm) https://feeds.transistor.fm/from-probe-to-practice From Probe to Practice is a weekly podcast on musculoskeletal ultrasound — diagnostic scanning, ultrasound-guided injections, and how MSK ultrasound changes the way clinicians practice regenerative and musculoskeletal medicine. Hosted by Colin Rigney and Ryan Martin, founders of the Advanced MSK Ultrasound Center, who have trained clinicians for years and bring the reps to prove it. This is not a 45-minute monologue on probe physics. It's a high-energy dialogue about what actually happens inside a practice: the diagnostic gaps nobody mentions, the injections that miss and why, the referrals you didn't need to make, the business of integrating ultrasound, and the case studies that only come from tens of thousands of scans. Plus, in Ryan's words, "a lot of dirt on each other." Every episode is built around one promise: take something you learned from a podcast on Friday and implement it on Monday. For physicians, regenerative medicine clinicians, sports medicine providers, anyone preparing for the RMSK exam — and anyone who works alongside them. Because you can't diagnose what you can't see.

He grew up watching his dad, his partner at Sellers Sports Medicine and Family Practice, cover sports from the sideline, then trained at Creighton and in the sports medicine fellowship at UNLV, where the rule was that the better diagnostician you are, the better proceduralist you will be. Tom explains how point of care ultrasound unlocked prompt care in his clinic: an exam and a scan on the same day instead of weeks of x-rays, physical therapy and an MRI that insurance denies. He walks through why he is team ultrasound, with no injection anywhere in the body that is not image guided, and how a suprascapular nerve block before a supraspinatus PRP keeps lidocaine out of the tissue. Asked where his field will be in 10 years, he sees better orthobiologics, energy modalities like laser and shockwave, and way less surgery, because his favorite thing to say is you don't need surgery. Plus why none of what he does is magic, the osteopathic principle of the body's innate ability to heal, the book Who Not How, and why you can't learn MSK ultrasound in a weekend seminar.

Is it going to take your job? Ryan Martin and Colin Rigney spent a long time tracing and measuring hundreds of patellar tendon, Achilles and plantar fascia scans by hand to help train an AI, and they explain what that taught them: the algorithms run on statistics, imaging is variable, and it all still comes down to the human input. AI will make smart people smarter, but you still need deep sono anatomy to know whether to trust what it tells you, and the human element stays at the center of care. Then the second topic: dynamic or it didn't happen. The advantage ultrasound has over MRI, CT and x-ray is the ability to assess tissue in motion, yet most cases on social media are static images. Why physical therapists, athletic trainers and sports medicine physicians pick up dynamics faster, why the biggest gap is anatomy, and why, if you are not using dynamic capability, you are just taking pictures.

MRI and ultrasound are complementary tools, and the skill is knowing which one to use and when. Second, palpation theater: "my hands are history enough", why precision is the most important lever in needle-guided orthobiologics, and the question to ask any clinician who relies on special tests alone: why would you not want that information?

Colin Rigney is joined by Matthew Gillogly, founder and CEO of Mavrix Profit System and author of Out of the System. Matthew is not a physician: he built three cash pay clinics, sold them, and now helps doctors leave insurance dependency and build practices they actually own. They talk about the squeeze on doctors and patients, private equity in healthcare, and why Matthew sees no future in insurance-based care. Then the business of a cash pay practice: why it is not only for the wealthy or the big city, who the core patient is, how to price so that price signals your skill, and why volume medicine is a false gospel when the true cost of a PRP injection is higher than most clinics charge. Just as important is the internal shift: Dr Janet Ang's first year in her own practice, two-way doors, the future self, and why "I'm trying" keeps doctors stuck. Matthew previews his opening keynote for the AMSKU Annual Global Summit '26 on 5 December: what the next 10 years hold for regenerative medicine and the doctors who choose agency over their lives.

]]> Is insurance a physician's lifeline, or a leash? Colin Rigney is joined by Matthew Gillogly, founder and CEO of Mavrix Profit System and author of Out of the System. Matthew is not a physician: he built three cash pay clinics, sold them, and now helps doctors leave insurance dependency and build practices they actually own. They talk about the squeeze on doctors and patients, private equity in healthcare, and why Matthew sees no future in insurance-based care. Then the business of a cash pay practice: why it is not only for the wealthy or the big city, who the core patient is, how to price so that price signals your skill, and why volume medicine is a false gospel when the true cost of a PRP injection is higher than most clinics charge. Just as important is the internal shift: Dr Janet Ang's first year in her own practice, two-way doors, the future self, and why "I'm trying" keeps doctors stuck. Matthew previews his opening keynote for the AMSKU Annual Global Summit '26 on 5 December: what the next 10 years hold for regenerative medicine and the doctors who choose agency over their lives.

Ryan Martin and Colin Rigney make their predictions. They start with AI assisted diagnosis: why AI will make smart clinicians smarter and expose the ones who use it poorly, why you should not rely on it 100 percent yet, and who takes the liability when an algorithm reads the image. Then robotic blood draws and needle guidance, what could replace today's injections, and why regenerative medicine will be market driven. On point of care, Colin makes the case that AI can already take a history more consistently than a human and that one appointment should send a patient home with all the answers, while Ryan pictures an AI guided ultrasound delivered to the patient's door. They close on the independent MSK clinic: same day diagnosis and treatment becoming the standard, and why corporate healthcare and the high-touch independent practice can both grow.

Why Training Beats the Objection full fe3fbdb2-1d1b-4a6c-98a4-9f30a7f429ac https://share.transistor.fm/s/3ecc3ee6 "It's so user dependent." It is the objection Ryan Martin and Colin Rigney hear more than any other about bringing MSK ultrasound into practice. In this episode they take it head on. X-rays are position dependent, MRI is reader dependent, surgery has its errors too, and every one of them is learned as a system. Ultrasound is no different: a systematic scan, enough reps with feedback, and a mentor beside you. They share how an ER physician got comfortable with a technical procedure in about 50 reps, how a resident went from no ultrasound at all in February to ultrasound guided PRP and bone marrow procedures a few months later, and why you cannot learn a hands-on skill from YouTube alone.

What this episode covers:

  • Why user dependence is the objection that comes up most about MSK ultrasound
  • Operator dependence in every modality: x-ray positioning, MRI reading, surgery
  • Ultrasound as a system: shining a flashlight under the skin and working your checkpoints
  • Plays are made to be broken, once you know the playbook
  • Not operator dependent, system dependent
  • How many reps it really takes: 50 and a backboard to learn from
  • The road to mastery goes through incompetency

What this episode covers:

  • Why a cuff fails anteriorly to posteriorly, and what that means for your scan order
  • The elongated myotendinous junction that gets called a bursal sided tear
  • Cortical irregularity across the middle facet, and why it is not a Hill-Sachs
  • Where the infraspinatus overlaps the supraspinatus, and the echogenicity change that fools people early in their scanning
  • Anisotropy versus pathology when the two tendons sit 30 to 45 degrees oblique
  • Assessing fatty atrophy in the posterior fossa, using teres minor as the landmark
  • Treating the whole organ rather than one tendon

A weekend course can hand you momentum. It cannot hand you competence. Colin Rigney and Ryan Martin come off a weekend of teaching and take the question straight on: I did a weekend course, what are your thoughts?

The answer starts with intent. Where is your skill set right now, why are you adding this one, and what do you actually want to be able to do at the end of it? Two clinicians can sit at the same table for the same two days and walk away with completely different things, and the difference is almost never the course.

Then there is the objection underneath all of it. "I don't have time." Ryan's answer is that you have time, everybody has time, and what you are really describing is a priority. That answer tells you more about the intent than any registration form does.

To be clear, because the hosts are: good weekend courses exist and both of them teach at them. A weekend is a launchpad. The reps after it are the actual work.

The Monday-morning takeaway: before you book the next course, write down what you want to be able to do when it ends. If you cannot name that, another weekend will not get you there. If you can, you have just turned a course into a starting point.

Every tissue has a signature. Bone is bright white. Tendon and ligament are fibrillar, like a guitar string. Nerve in short axis is a bundle of grapes, or a honeycomb. Muscle is sinuated and feathery. Fat is marbled. Learn those cold and pathology announces itself, because pathology is a departure from a picture you already hold.

Skip that step and the screen will hand you a diagnosis you invented. Tip the probe a few degrees and a normal tendon goes dark, and dark reads as pathology. As Ryan Martin puts it, you check the contralateral side, you do everything right, and really all it was was a difference in how you held the probe.

Colin Rigney and Ryan Martin spend this episode on reading echo texture and the pattern recognition underneath it. Also in this episode: how to tell nerve from tendon when they look identical in short axis (make the tendons glide and watch what stays still), how to separate a fat pad from the quad tendon by pushing on the skin, the three questions Colin asks at every tendon-bone interface, why a cortical change on the infraspinatus means something different from the same change on the supraspinatus, the little dip before the enthesis that will let you invent a tear at the critical zone, and why an isolated infraspinatus tear is rare enough to make you look again.

Tip the probe a few degrees off perpendicular and less sound comes back to it. Less sound back means a darker picture. A darker tendon reads as hypoechoic, and hypoechoic reads as torn. The image still looks fine. The finding is invented.

Colin Rigney and Ryan Martin spend this episode on the two things that decide whether you can trust what is on your screen: anisotropy, the artifact that fools everyone early and that experienced scanners turn into a tool, and the vocabulary underneath it — hyperechoic, hypoechoic, anechoic, homogeneous, heterogeneous — which most clinicians use loosely and the RMSK exam does not.

Also in this episode: how to toggle the probe to make peroneus longus and brevis wink at you one at a time, how far off 90 degrees you can be before it costs you (about five degrees, and it is obvious by fifteen), why the Achilles is the tendon most people position wrong, Dr. Joel Sellers' wall test for telling homogeneous from heterogeneous, what a denervated muscle looks like as it loses water and takes on fat, and why the contralateral side is the cheapest control you have.

If you can't diagnose it, you can't inject it."

Dr. Greg Zakas trained in physical medicine and rehabilitation, did an interventional pain fellowship, and spent years in clinics where the model was opioids first and procedures second. He came out the other side as a full-time regenerative orthopedics physician. This is the whole route, told honestly — including the $400,000 of debt that shaped which specialty he picked, the forty-to-fifty-patient days that made real conversations impossible, and the VA research that settled the opioid question for him.

Colin Rigney and Ryan Martin take him through the part most clinicians get wrong: the assumption that ultrasound-guided injection is the hard skill. Zakas argues the needle work is the easy half. What separates practitioners is whether they can see the thing they are treating in the first place — and he makes the case that in trained hands, diagnostic ultrasound matches MRI for finding rotator cuff tears.

Also: why showing a patient their own tear on the screen builds more trust than any explanation, how the ability to talk about ultrasound and the ability to do it feed each other, why he refused to post about anything he had not seen dozens of times, and what he would tell a physician who is ten years behind him and wondering whether it is too late.

The Monday-morning takeaway: the diagnostic skill is the bottleneck, not the needle. If you are getting your orthobiologic into the joint but not to the lesion, more injection practice is not the fix.

Which frequency? And what should you actually be doing before the probe touches the patient?

Colin Rigney and Ryan Martin open From Probe to Practice with the decisions that quietly set the ceiling on every MSK ultrasound exam you run — probe selection, frequency, gain, and the positioning nobody talks about until an injection goes sideways.

Ryan's rule, from his mentor Wayne Smith: "Scan everything with a linear probe until you cannot." Colin's version of the same idea: "Ultrasound is an extension of your clinical brain." Both come back to intent — why are you scanning, and will it change what happens to this patient?

Also in this episode: a case from that same morning where a patient's anterior hip sat almost 12 cm deep and the linear probe simply could not reach it, why the curvilinear's crossing arrays can make a straight bone look curved, what to do when your clinic owns exactly one probe, and the scouting habit that prevents the most common avoidable injection problem.

The Monday-morning takeaway: always scout in the position you're going to inject in. A shoulder scouted seated and injected supine is a different shoulder.

Colin Rigney and Ryan Martin — the founders of the Advanced MSK Ultrasound Center — introduce From Probe to Practice: what it is, who it's for, and why they built a show about musculoskeletal ultrasound that deliberately isn't a lecture.

This is not a 45-minute monologue on probe physics. It's two people who've trained clinicians for years talking about how MSK ultrasound actually works inside a practice — the diagnostic gaps nobody mentions, the injections that miss and why, the referrals you didn't need to make, the business of integrating it, and the case studies that only come from tens of thousands of reps. Plus, in Ryan's words, "a lot of dirt on each other."

Guests this season include Greg Zakas and Don Buford, among others from across regenerative and musculoskeletal medicine. Stay to the end for a look at what's coming.
