“…Joint selection was based mainly on the fact that these are the most common peripheral joints involved in JIA (3,6). Since many MSUS publications focused on pediatrics have included the hip joint, we decided not to include it in the present study (7,8). The children were divided into 4 groups according to age-related changes reported previously by Roth et al (5) and based on the knowledge of appearance of bone ossification as detected by radiography (9)(10)(11)(12).…”

Objective. The Outcome Measures in Rheumatology Ultrasound Task Force has recently started to work on the validation and standardization of musculoskeletal ultrasound (MSUS) examination in children in order to improve its applicability to joint examination. Methods. This was a prospective multicenter study performed by 4 experts in pediatric MSUS, who independently collected representative images using predefined scanning procedures of 4 joints (knee, ankle, wrist, and second metacarpophalangeal joint) in different predefined age groups. Researchers were allowed to use their own settings (B-mode and Doppler) in order to get the best quality image and highest sensitivity for low blood flow. Images were evaluated for quality parameters and an atlas was created with the best images. An equipment comparative study was performed by a single examiner using 2 different types of machines. Results. Sixty-four healthy children were scanned. The quality of evaluated images, obtained by predefined scanning positions, was highly comparable among the examiners. The B-mode images clearly showed age-related variations of joint findings, while Doppler images showed the presence of blood flow, particularly within the epiphyseal cartilage of the children at a younger age. There was a high to good level of consistency between images obtained from the 2 different ultrasound machines. Conclusion. The study shows a systematic method for ultrasound examination of children at different age groups. Additionally, a baseline collection of images was developed, showing blood vessels in the joints examined. The present study could provide a framework for ongoing MSUS studies as well as for clinical practice in pediatric rheumatology.

“…A hip joint effusion is diagnosed with the presence of anechoic or hypoechoic distention of the anterior recess of the hip capsule over the femoral neck [26]. Labral pathology may also be rudimentarily identified as a hypoechoic cleft or detachment in an otherwise hyperechoic, smooth, triangular-shaped labrum.…”

Hip arthroscopy is one of the fastest growing surgical procedures performed by orthopaedic surgeons, with the number of hip arthroscopies expected to double in 2013. The increase in surgical prevalence is at least in part due to an increased awareness of prearthritic hip pathology. The diagnoses of prearthritic hip conditions are made through a comprehensive history, physical examination, and selection of appropriate diagnostic imaging modalities. The purpose of this review article is to provide the practicing orthopaedic surgeon with an overview of the imaging modalities available for the diagnosis of prearthritic hip pathology, with a focus on literature supporting advancements in imaging techniques and new applications of existing modalities.

“…3). This can be explained by the fact that the thickness of these layers, measured at histological examination, is approximately 0.025 mm, which exceeds the spatial resolution of US [4]. A US sign that is always present in patients affected by this pathology is joint effusion in the hip joint anterior recess (Fig.…”

KEYWORDSTransient synovitis; Hip; Hip pain; Ultrasonography.Abstract We describe the ultrasound (US) appearance of transient synovitis. Transient synovitis of the hip typically occurs in 3 to 8-year-old children. The onset is clinically characterized by acute hip pain and limp with limited joint mobility, and the leg is usually held in a position of flexion and external rotation to avoid pain. US image is characterized by joint effusion in the hip joint anterior recess, as described in the literature. Our experience confirms the importance of the technique with which the US examination is performed. In order to obtain the best diagnostic information the hip must be examined with the patient in the supine position and the hip joint in a neutral position (abduction of the hip with extension and slight external rotation) by means of an anterior approach along the long axis of the femoral neck in the parasagittal plane.Sommario Viene descritto l'aspetto ecografico della sinovite transitoria dell'anca. La sinovite transitoria dell'anca colpisce tipicamente i pazienti di età pediatrica, compresa tra 3 ed 8 anni; il suo esordio è clinicamente caratterizzato da un'insorgenza acuta di dolore all'anca e zoppicamento con limitata motilità articolare ed atteggiamento antalgico in flessione ed extra-rotazione. L'aspetto ecografico è caratterizzato da versamento articolare a livello del recesso anteriore dell'anca, come descritto in letteratura. La nostra esperienza conferma l'importanza della tecnica di esecuzione dell'ecografia, infatti per ottenere le migliori informazioni diagnostiche l'anca deve essere esaminata a paziente supino con l'articolazione in posizione indifferente (estensione e lieve extra-rotazione) mediante una scansione anteriore secondo un piano para-sagittale rispetto all'asse lungo del collo del femore. ª

Anterior Joint Capsule of the Normal Hip and in Children with Transient Synovitis: US Study with Anatomic and Histologic Correlation

Abstract: Increased thickness of the anterior joint capsule in transient synovitis is caused entirely by effusion. There is no US evidence for additional capsule swelling or synovial hypertrophy.
