https://youtube.com/shorts/eIqs_44BGUI OverviewDistal biceps tendinosis is a chronic degenerative condition characterized by collagen disorganization, mucoid degeneration, and tenocyte hypertrophy. Unlike tendinitis, which implies an acute inflammatory process, tendinosis reflects a failed healing response to repetitive microtrauma and mechanical overload.1. Signal CharacteristicsKey Concept:Ten..

Basic StructureDistal biceps tendon is a flat, paratenon-lined, extrasynovial structureNo true tendon sheathFormed by contributions from the short head (SHB) and long head (LHB)Tendon formation begins approximately 7 cm proximal to the elbow2. Myotendinous ConfigurationSHB and LHB gradually coalesce distallyInterdigitating fibers create a “goose quill ap..

https://youtube.com/shorts/w39HxJSCbXc An imaging pitfall radiologists should not missRecurrent pain after tarsal tunnel release is often attributed to residual or recurrent entrapment or a new space-occupying lesion.However, imaging occasionally reveals a different and easily overlooked entity:neuroma in continuity (NIC) of the posterior tibial nerve.Unlike an end-bulb neuroma, NIC occurs after..

https://youtube.com/shorts/ZrOE59qxC2s Why it mattersTarsal tunnel symptoms vary widely because tibial nerve anatomy and branching are highly variable.Accurate MRI-based localization is critical for diagnosis and surgical planning.Tibial nerve: courseThe tibial nerve is the largest branch of the sciatic nerve, traveling with the posterior tibial vessels.It runs deep to the soleus and enters the ..

Medial Malleolus Level: The Key Coronal SliceThis mid-to-posterior coronal slice is a high-yield teaching view, allowing simultaneous evaluation of the tarsal tunnel, peroneal tendons, and major ankle ligaments.Medial Side — Tarsal Tunnel (Anterior → Posterior)Use the classic mnemonic “To..

https://youtube.com/shorts/XWBREO-XWTo Why this mattersScapholunate ligament (SLL) tears are common in distal radius fractures, especially intra-articular and complex patterns.Many are clinically silent at initial reduction, but untreated instability can progress to SLAC wrist.These injuries are often not isolated, frequently associated with lunotriquetral ligament, dorsal intercarpal ligament, ..
