⚠️ Educational demonstration only — not an actual surgery, no real patient involved. This is a model used to illustrate hand anatomy for clinicians and patients alike. Ever wonder why your finger “catches” or locks when you bend it? 🖐️ This is trigger finger — caused by the flexor tendon catching on a tight band of tissue called the A1 pulley. The surgical fix is simple: release that pulley (not the tendon!) to restore smooth gliding motion. Education matters — know your anatomy! 💪 #HandTherap
