Stenosing tenosynovitis refers to the adhesion of the tendon to its tendon sheath. MRI and ultrasound may show loculated tendon sheath fluid. Ultrasound may show fixation of the tendon and sheath.
De Quervain disease is a stenosing tenosynovitis of the first dorsal wrist compartment. The extensor pollicis brevis tendons is most commonly involved, but the abductor pollicis longus tendon can also be involved.
Patients with os trigonum syndrome commonly have stenosing tenosynovitis of the flexor hallucis longus tendon.
