title: [Role of US in the management of de Quervain's tenosynovitis: review of 22 cases].
abstract: OBJECTIVE
  To assess the role of US in the management of de Quervain's tenosynovitis.
  
  
  METHODS
  Using a high-frequency transducer (12 MHz), sagittal and axial images were obtained of the first extensor compartment. The US features of 22 symptomatic patients were reviewed (positive Finkelstein's maneuver).
  
  
  RESULTS
  US findings included tendon thickening and synovial sheath thickening with peritendinous edematous changes resulting in a peritendinous hypoecoic halo in all patients. An intertendinous septum was identified in two patients.
  
  
  CONCLUSIONS
  US can confirm the suspected diagnosis and provide follow-up of lesions. It can confirm the presence of an intertendinous septum and provide guidance at the time of steroid injection. It can increase the rate of conservative management by demonstrating the absence of septum.
