Case 158 Asset 1 De Quervain's Tenosynovitis

Video Transcription

Video Summary

The transcript explains ultrasound evaluation of De Quervain’s tenosynovitis. It first reviews normal first dorsal compartment anatomy, including possible septation between the abductor pollicis longus and extensor pollicis brevis tendons and their normal fibrillar appearance. It then describes abnormal findings in De Quervain’s disease: tendon sheath thickening, fluid/effusion, peritendinous edema, tendon enlargement, septal and retinacular thickening, hypoechoic tendon changes, loss of fibrillar texture, and increased Doppler flow indicating hyperemia/neovascularity. The key point is that ultrasound often shows both tenosynovitis and tendinopathy in affected wrists.
