كتف ثلاثي الأبعاد

A professional YouTube thumbnail with a split-screen design. On the left side, a dark textured charcoal background featuring bold glowing neon white and cyan blue text. At the top, it reads "ROTATOR CUFF REHAB". Directly below it, add beautifully rendered, connected modern Arabic typography that reads "علاج آلام الكتف". Below that, glowing neon yellow text reads: "SCAPULAR INSTABILITY". On the right side, a clean medical anatomical illustration of a human upper back and shoulder from a posterior view, highlighting the scapula and rotator cuff muscles. An intense, localized red glowing circle marks the exact spot of pain on the posterior shoulder cuff, with a clean pointer arrow and the English labels "Supraspinatus" and "Infraspinatus". Extremely clean, high-end clinical aesthetic, no play buttons or extra icons.
