  • Title: Sonographic evaluation of hip effusion in children. Improved visualization with the hip in extension and abduction.
    Author: Chan YL, Cheng JC, Metreweli C.
    Journal: Acta Radiol; 1997 Sep; 38(5):867-9. PubMed ID: 9332246.
    Abstract:
    PURPOSE: To assess the difference in the sonographic appearance of hip effusions when the hip was placed in the extended and abducted position as compared to a neutral position. MATERIAL AND METHODS: Twenty-one consecutive children (aged 2-14 years) with hip pain or limping were examined for hip effusions by means of ultrasound. The capsule-femoral-neck distance, the presence of joint fluid, and the shape of the anterior capsule were compared in hips in slight extension and abduction with those in hips in a neutral position. RESULTS: Of the 11 positive hip effusions, the maximal distance between the capsule and femoral neck was significantly larger (p < 0.005) in the extended and abducted hip position than in the neutral hip position, with a mean difference of 1.6 mm. Convex bulging of the anterior capsule was more confidently diagnosed in 3 hip effusions in the extended and abducted hip, and better visualization of fluid between the capsule and femoral neck was achieved in 4 joint in this posture. CONCLUSION: The study demonstrated an improvement in the sonographic detection of hip effusion in the extended and abducted position compared to the neutral position.
