Rim resection in a patient w/ overcoverage. A pitfall in arthroscopic management of pincer impingement is to assess extent of osseous trimming. Over-resection of acetabular rim can destabilize hip w/ risk of postoperative anterior dislocation #radiology #orthopaedics #sportsmed

Pincer-type FAI w/ extended anterior overcoverage. Other terms used to characterize this type of proximal acetabular linear overcoverage include anterosuperior overhang & cephalad retroversion, cont. reading on pg 492 of Stoller's #TheHip #radiology #orthopaedics #sportsmedicine

Prominent and coarse collagen fibers directed in a parallel and circumferential direction to the meniscal periphery allow this middle layer to resist tensile forces, continue reading on page 168 of Stoller’s Orthopaedics & Sports Medicine: The Knee.

Idealized structure of meniscal fibrocartilage with peripheral circumferential & perforating fibers. The middle layer of the meniscus functions in load transmission across the joint. continue reading on pg 168 of Stoller’s #Orthopaedics & #SportsMedicine: #TheKnee #MRI #radiology

In abduction, tendon layers may separate, and as abnormal force distribution increases, the interstitial tear propagates from the footprint bone bed laterally to an intratendinous horizontal plane medially.

Idealized interstitial tear plane in which collagen layers of the rotator cuff tendon are not tensioned, improving visualization of fluid signal intensity between tendon layers, continue reading on page 271 of Stoller's The Shoulder #StollerMSKcourse #radiology #orthopaedics #MRI

When the blistered articular cartilage of the acetabular roof is probed, it elevates off the substrate subchondral bone causing a “wave effect”. There is continuity of chondral delamination w/ chondrolabral junctional pathology, continue reading on page 574 of Stoller’s The Hip

“Wave effect” of acetabular roof articular cartilage arthroscopically viewed from central compartment. “Wave sign” at arthroscopy represents fatigue injury of the collagen fibers within deep radial zone. #orthopaedics #Hip #MSK #MRI #SportsMedicine #StollerMSKcourse

Mini-Fellowship Workshop Description (8 AMA PRA category 1 credits): 1 day workshop course in which Dr. Stoller reviews entire DICOM MRI cases of all 6 appendicular joints on a full workstation projected in front of a small group audience, stollerMSKcourse.com

(6 SAM credits & 18 AMA PRA category 1 credits) Dr. Stoller delivers 18 didactic lectures on the entire spectrum of orthopaedic MR imaging of the joints.A checklist emphasis is used to enable participants to understand the proper approach to cases as well as interpretation pearls

Decreased anteversion may lead to decreased internal rotation + anterior femoroacetabular impingement, continue reading on page 180 of Stoller's Orthopaedics & Sports Medicine: The Hip #StollerMSKcourse #TheHip #orthopedics #imaging #MRI #magneticresonanceimaging #radiology

High femoral anteversion (with decreased external rotation) can be associated with a posterior extra­ articular femoroacetabular impingement.

Anteversion is defined by the angular delta/difference between the axis of the femoral neck & transcondylar axis of the knee. In femoral anteversion, the femoral neck is directed anteriorly relative to the femoral diaphysis, resulting in internal rotation of the lower extremity.

@morrisonMSK Outstanding lectures as always. Thank you!

Honored to be speaking at the Stoller course in Las Vegas- an awesome course!! stollermskcourse.com @DavidStollerMD #radiology
