Application of sonography for arthrocentesis in the hip / 中华超声影像学杂志

ABSTRACT

ObjectiveTo evaluate the value of uhrasonography for arthrocentesis in the hip and the advance of the femoral head/acetabulum as the puncture location in patients without sonographically obvious joint effusion.Methods Forty-three patients diagnosed with ankylosing spondylitis or osteoarthritis were included,82 hip joints were involved and received ultrasounded-guided intra-articular injections.The puncture site was the joint space between the femoral head and the acetabulum.The times,depth,procedure time,side effects and complications of each injection were recorded.ResultsAll 82 hips could be explicitly displayed.The depths from the skin surface to the joint space were (3.4 ± 0.9)cm (left)and (3.1 ± 0.8)cm (right),respectively.Overall,100％ of hip joints were punctured successfully,and 95.1％ of them were succeeded with the first arthrocentesis.The procedure time was (287.9 ± 45.8) s.No side effects or complications were observed.ConclusionsThe sonographic technique could be used as a primary method of image guidance for performing hip arthrocentesis and the joint space between the femoral head and the acetabulum could be a choice of target location for the patients without joint effusion.
