Effusion in the Hip Joint on Ultrasound: Measurement of the Anterior Recess and Threshold in mm
The provided SOURCE FRAGMENTS lack information directly related to the measurement of the anterior (anterosuperior) recess of the hip joint, the methodology for assessing effusion in this joint, and specific millimeter thresholds at which effusion is interpreted as pathological. Therefore, key numerical parameters of the topic cannot be provided without the risk of introducing unverified data.
What is Missing in the Source
The following critically important positions for the topic are not presented in the source and require [clarification] according to specialized guidelines:
| Parameter | Status in the Source |
|---|---|
| Threshold of anterior recess thickness (mm) | [clarify] — absent in fragments |
| Measurement methodology (plane, reference point) | [clarify] — absent in fragments |
| Asymmetry criterion with the healthy side | [clarify] — absent in fragments |
| Reference values in children/adults | [clarify] — absent in fragments |
Related Data Available in the Source
From the available fragments, only the general topic of quantitative assessment of joint effusion by ultrasound on the example of another joint is indirectly related to the topic of joint effusion: the bibliography mentions a study on the detection and quantification of effusion in the shoulder (glenohumeral) joint and the reliability of ultrasound (Zubler V, Mamisch-Saupe N, Pfirrmann CW et al., Eur Radiol, 2011). However, specific methodologies, values, and thresholds are not provided in the text fragments, and data on the hip joint are completely absent.
Thus, it is impossible to provide a methodologically correct answer indicating the anterior recess and millimeter threshold based on the provided source. It is recommended to supplement the request with specialized fragments (e.g., on MSK-US of the hip joint).
Frequently asked questions
