The Medial Collateral Ligament has a deep component made up of two ligaments—the meniscofemoral ligament (MFL) and the meniscotibial ligament (MTL). The MFL is the most frequently injured, with its most likely site to rupture at the femoral insertion (+/- 80%). The MFL primarily provides stabilization against external rotation.... show more

What is the treatment of a deep menisco-femoral full tear ? (And the cost of missing it on MRI)

I love this but also I notice that the MFL is frequently absent in older knees - when would you call it injury and when would you call it degenerate?

Continuation of previous MRI case. A 14-year-old boy with persistent discomfort and occasional joint effusion 3 months after a medial knee sprain of the deep component (same injury 3 years ago). We have already seen the MRI. Ultrasound confirms a residual proximal tear of the deep MFL LCM with an insufficient ligament. Dynamic maneuvers with knee valgus in slight flexion demonstrated an insufficient ligament with meniscal hypermobility with the meniscus penetrating the joint with the knee valgus. The deep MCL component STABILIZES THE MENISCUS!! We can provide essential information for decision-making with dynamic US. #mskrad

Morton's neuroma occurs at the terminal bifurcation of the common plantar digital nerve. The deep transverse metatarsal ligament connects the metatarsals. Below the ligament, we find the nerve, and above the ligament, the bursa. And distal to the anterior free edge of the ligament, the neuroma. It is at this level that the nerve makes a pronounced dorsal turn at the distal free edge of the ligament. We can see this demonstrated in the video/illustration. This explains one of the theories; entrapment between the plantar soft tissues and the ligament. The dorsal approach for me is the best 👍 . We avoid the thick plantar skin. Compressing with the finger on the plantar side and sliding it also lets us differentiate the distinct components, where the ligament remains immobile. We can also mobilize the nerve and see how it imprints against the anterior free edge of the ligament, understanding the pathomechanism. Finally, the Mulder maneuver always helps. #mskrad

The soft tissue components of the biceps pulley system include: •Subscapularis •Supraspinatus •The coracohumeral ligament (CHL) •The superior glenohumeral ligament (SGHL) The subscapularis has superficial and deep fibers that envelope the groove, creating the “roof” and “floor”. They also coalesce with those from the supraspinatus and SGHL/CHL complex. They attach at the lesser tuberosity to create the proximal and medial aspects of the pulley system, with soft tissue extensions serving to further envelope the LHBT in the bicipital groove. #mskrad

Instability of the long head of the biceps tendon (LHBT) is almost always associated with other shoulder pathologies, mainly pathology of the rotator cuff (supraspinatus and subscapularis tear). Therefore, every time we find RC tears, we must explore the stability of the LHBT. The most critical stabilizers are the SGHL, CHL, and the intertwining fibers of the supraspinatus and subscapularis. Here is a case with a high-grade subscapularis tear with continuity of the most superficial fibers/transverse humeral ligament that limits retraction,associated with medial dislocation of the LHBT. With an extension, abduction, and internal rotation maneuvers of the shoulder, we reposition the tendon in the bicipital groove, with subsequent re-dislocation due to external rotation, showing a marked exit snapping, very painful. We can add important dynamic information. #mskrad #MedTwitter

Complete rupture of the flexor digitorum superficialis (FDS) tendon 📍 Distal insertion at the middle phalanx, with retraction to the base of the proximal phalanx. 🧗‍♂️ 20-year-old climber with sudden, sharp pain during climbing. 🔍 Key point of this case: dynamic clinical–ultrasound correlation ▶️ First part of the video (most important): The distal phalanx is actively flexed while blocking the DIP joint. This maneuver isolates the flexor digitorum profundus (FDP), so on ultrasound we should see only FDP excursion — which is exactly what happens. The distal phalanx is flexed without blocking the DIP joint, allowing flexion of the PIP joint. In this situation, both FDP and FDS should normally show excursion. ❌ However, the FDS remains completely still, confirming complete tendon–bone dissociation. ▶️ Second part of the video: 🩻 Final confirmation: • Empty tendon sheath at the expected distal insertion • Retracted FDS tendon stump proximally 🎯 Take-home message: Dynamic ultrasound, combined with proper clinical maneuvers, is crucial to demonstrate functional dissociation and accurately diagnose complete FDS rupture, especially in climbers. #mskrad

#Patriots tackle Will Campbell made it to the #SuperBowl in his rookie season, but clearly was disappointed with his performance in the big game. He also revealed today that a torn ligament in his knee sent him to injured reserve for four games late in the #NFL regular season.

FOR THOSE INTERESTED IN THE SUPRASCAPULAR NERVE CASE AND HOW TO LOCATE IT. Normal Anatomy: To TRACK the SUPRASCAPULAR NERVE with ultrasound, start at the supraclavicular fossa. A high-frequency linear probe is used to identify the SUPERIOR TRUNK of the brachial plexus, which is seen as a “honeycomb” structure BETWEEN THE ANTERIOR AND MIDDLE SCALENE MUSCLES. Locate the suprascapular nerve as a small branch from the superior trunk, then follow it laterally and posteriorly beneath the OMOHYOID MUSCLE. Continue tracing it toward the suprascapular notch, which passes under the superior transverse scapular ligament. KEY LANDMARKS include the scapular spine and coracoid process. Look for signs of hourglass constriction, such as nerve flattening, hypoechoic areas, or fascicular swelling. Proper alignment and dynamic scanning are essential for clear visualization. #mskrad

In India’s illegally occupied Manipur, fighters of the Kangleipak Communist Party (KCP) and its armed wing Miyamgi Fingang Lanmi (MFL) are seen moving freely across the region, a clear sign that New Delhi’s repressive grip is crumbling. The growing strength of Manipur’s liberation movements reflects the deep-rooted desire for freedom among its people. Historically known as Kangleipak, the region continues to resist Indian military occupation and struggle for its rightful independence.

Addressing the European Council, I stated: the world is clearly unstable. But the EU plays a key role in preventing Russia’s war from spreading and in moving toward peace. Its sanctions against Russia remain one of the most effective tools for limiting the aggression.

Cyclops injury. Also known as localized anterior arthrofibrosis, it is almost exclusively a complication of ACL reconstruction, with the appearance of an ovoid nodule most commonly located on the anterior aspect of the ACL graft near the tibial insertion. Risk factors female gender, greater graft volume, bone avulsion lesions, excessive anterior tibial tunnel, and double-bundle ACLR. This case is a 23-year-old man, a high-level athlete, with limited and painful terminal knee extension post-ACLR. The relationship of the cyclops lesion with the limitation of the knee extension during flexion-extension maneuvers can be observed. Undoubtedly, magnetic resonance imaging of the knee is the imaging study of choice. Still, dynamic ultrasound can be an excellent complement to demonstrate to the patient and treating physician its causality. #mskrad

Adhesive capsulitis of the hip: diagnosis A 55-year-old patient with gluteal pain of 6 months' duration associated with decreased range of motion of the hip joint. An AMRI is requested to rule out a tear of the acetabular labrum. The study shows an increase in thickness of the lower and upper bands of the iliofemoral ligament (measuring 13 and 15 mm, respectively) associated with pericapsular edema, consistent with adhesive capsulitis. An ultrasound-guided intra-articular infiltration of 1 cc of Trigon and 1 cc of 2% mepivacaine is performed, and the pain is entirely resolved after five days. Treatment is associated with physiotherapy and rehabilitation, and the range of joint mobility recovers after three weeks. In the article “Capsular ligaments of the hip: anatomic, histologic, and positional study in cadaveric specimens with MR arthrography” (doi: 10.1148/radiol.12111320), the average thickness of the capsular ligaments of the hip joint is described.

Jayden Daniels Right hamstring vs. knee injury His hamstring was stretched in an abnormal position. If his knee is involved, it’s most likely an injury to his (posterior) meniscus. ACL unlikely but possible. You would think it would have been to his left knee the way it bent but no. That was the knee he previously injured. You can see him grab the back of his right leg/knee at the end of the play.

The Lower Traps are a key muscle for shoulder health and function, but most people overlook this key aspect of training it. It has a key role in controlling the rotation of the shoulder blade on the ribcage, especially as the arm goes overhead. Here’s how to effectively train it 💪🏼

An initial analysis from the great Brian Sutterer MD on what may have happened to Conor McGregor: "Didn't see the classic shift you'd expect with an obvious ACL injury. I'd say meniscus is No. 1. An ACL is definitely possible and a concern, but it didn't have the definitive look we've seen in other cases. It would fit with some pre-existing meniscus issues coming into the fight that got worse on the landing."

Clamshells are one of the most overrated glute exercises. The glutes main action is hip extension, but they do have an abduction and external rotation component that the clamshell does train. However, the clamshell has a lot of limitations. A better alternative would be this exercise I modified and cue a bit different from Postural Restoration Institute.

The Syrian Revolution was one of the most important events to take place in the world in the past 15 year. In this decade and a half we've seen so much brutality, so much suffering, so much bloodshed. But also so much courage, determination, strength. And now with the liberation of Homs we can say the Syrian Revolution has prevailed! And the Assad regime with its bloodlust, its terror and its brutality. This modern embodiment of evil has now been defeated. #FreeSyria 💚🤍🖤
