📌 Labral Calcification: The MRI Low-Signal Trap

https://youtu.be/hmhqWsh7Vukhttps://youtube.com/shorts/_UNZ5r3dH1M Calcific Labritis (BCP Deposition in the Glenoid Labrum)Why this mattersShoulder calcific tendinitis is commonLabral calcification is rareRare things get miscalledThe common miscalls are expensive: infection or labral tear What it isBasic Calcium Phosphate (BCP) crystal depositionHydroxyapatite-type calciumCan deposit inside the ..

📌 Unstable OCD in Adults: What MRI Is Really Telling You

https://youtu.be/briyKxiAJVQ https://youtube.com/shorts/8ApMUe7aktcWhy This MattersIn adult osteochondritis dissecans, instability is not defined by fragment displacement.It is a biological problem, and MRI allows us to recognize instability before mechanical failure occurs.Core PrincipleIn adults, even ONE MRI instability sign = Unstable OCDWaiting for displacement means the biological window f..

📌 The Gravid Hip: Subchondral Insufficiency Fracture of the Femoral Head (Pregnancy & Puerperium)

https://youtu.be/jz3XQMZ3SKAhttps://youtube.com/shorts/mwgqySnkXEEWhat it is In late pregnancy / early postpartum, severe hip pain with diffuse femoral head BME is often labeled “TOH,” but small-FOV MRI frequently reveals an occult subchondral fracture line.Practical takeaway: TOH and SIF are a spectrum, and the fracture (SIF) is the structural event that drives the edema. MRI: must-mention find..
