Technical note: Identifying and aspirating hip effusions
Berman L., Fink AM., Wilson D., McNally E.
Ultrasound has become a routine investigation in the investigation of the painful hip in children. It has been recommended that all effusions demonstrated by sonography be drained. Based on the experience of 800 hip aspirations, the authors describe an approach to the demonstration and aspiration of hip effusions with some of the pitfalls that result in false positive and false negative diagnoses.
