title: Intra-articular hip injections using ultrasound guidance: accuracy using a linear array transducer.
abstract: OBJECTIVE
  To describe the accuracy of sonographically guided intra-articular hip injections with a linear array transducer.
  
  
  METHODS
  Retrospective review.
  
  
  METHODS
  Private outpatient clinic.
  
  
  METHODS
  A single experienced operator performed 11 ultrasound-guided intra-articular hip injections by using a linear array transducer. Intra-articular placement was confirmed with contrast agent and fluoroscopy.
  
  
  METHODS
  Assessment of injected contrast within the hip joint via fluoroscopic imaging.
  
  
  RESULTS
  All 11 sonographically guided hip injections were accurately placed within the hip joint by the use of a linear array transducer (100% accuracy).
  
  
  CONCLUSIONS
  This retrospective review suggests that physicians who use a linear array transducer can accurately perform intra-articular hip injections in an outpatient setting.
