Diferenciación de sinovitis transitoria y artritis séptica de cadera con criterios clínicos y ecográficos
ABSTRACT IntroductionUltrasound does not distinguish between different types of synovitis. The aim of this study was to evaluate its contribution, together with several clinical data, in the diagnosis of septic arthritis (SA) and transient synovitis (TS) of the hip.

ABSTRACT: To determine standard reference values for musculoskeletal ultrasonography in healthy adults. Ultrasonography was performed on 204 shoulders, elbows, hands, hips, knees, and feet of 102 healthy volunteers (mean age 38.4 years; range 20-60; 54 women) with a linear probe (10-5 MHz; Esaote Technos MP). Diameters of tendons, bursae, cartilage, erosions, hypoechoic rims around tendons and at joints were measured with regard to established standard scans. Mean, minimum, and maximum values, as well as two standard deviations (2 SD) were determined. Mean values +/-2 SD were defined as standard reference values. Hypoechoic rims were normally present in joints and tendon sheaths owing to physiological synovial fluid and/or cartilage. Similarly, fluid was found in the subdeltoid bursa in 173/204 (85%), at the long biceps tendon in 56 (27%), in the suprapatellar recess in 158 (77%), in the popliteal bursae in 32 (16%), and in the retrocalcaneal bursa in 49 (24%). Erosions of >1 mm were seen at the humeral head in 47 (23%). Values for important intervals were determined. The correlation between two investigators was 0.96 (0.78-0.99). The reliability of follow up investigations was 0.83 (0.52-0.99). Fluid in bursae as well as hypoechoic rims within joints and around tendons are common findings in healthy people. This study defines standard reference values for musculoskeletal ultrasonography to prevent misinterpretation of normal fluid as an anatomical abnormality.Annals of the Rheumatic Diseases 08/2004; 63(8):988-94. · 9.11 Impact Factor

ABSTRACT: Intraarticular steroid therapy in juvenile chronic arthritis (JCA) is performed because of high local efficacy with few side effects. Imaging is used for initial evaluation and for monitoring of treatment response. The aim of this study was to compare imaging findings in diseased hips and knees before and after therapy. A prospective study was performed on 10 patients (15 joints) scheduled for intraarticular therapy. Pretherapeutic assessment included clinical work-up, radiographs, ultrasound (US), and magnetic resonance imaging (MRI) of affected joints. Following therapy, clinical and sonographic examinations were performed at 1 week and 1 month. MRI was repeated at 1 month. MRI and US demonstrated pannus formation and effusion, but differentiation was less distinct on US. Popliteal cysts and lymph nodes were visible in both modalities. MRI additionally revealed articular cartilage loss and subchondral cysts, not shown by US. Epiphyseal overgrowth and osteopenia were best seen radiographically. At present MRI is the best tool to assess the inflammatory changes of the joints in JCA. Initial staging of the joints may be done with plain films and MRI. US is useful to assess effusion and pannus and may be used to monitor treatment response.Pediatric Radiology 02/1994; 24(8):558-63. · 1.57 Impact Factor

ABSTRACT: Arthrotomy of the hip joint followed by a variable period of drainage or continuous irrigation and drainage is considered the accepted treatment of septic arthritis of the hip joint (SAHJ). The authors reviewed the results of a cohort of children with SAHJ with repeated aspirations of the hip joint. Thirty-four children diagnosed with SAHJ were treated with repeated aspirations of the hip joint. The aspirations were performed under ultrasound guidance and topical anesthesia or under sedation. After the aspiration the joint was irrigated using the same needle, and the procedure was repeated daily. Six of the patients were operated on and then treated with aspirations because of drain dislodgement or clogging. Twenty-eight of the patients were treated primarily with repeated aspirations. Four of those patients did not improve and underwent arthrotomies, and 24 were treated only by repeated aspirations and healed completely. The mean number of aspirations was 3.6 (range 3-5), and 75% of the patients resumed walking after 24 hours. The mean follow-up time was 7.4 years (range 3-18). No complications were seen. Repeated aspiration is a safe and efficacious method of treatment for SAHJ. This method of treatment is not associated with surgery and its complications and prevents scarring of the skin and the need for general anesthesia. Faster return to normal activity was noted in this series.Journal of Pediatric Orthopaedics 01/2004; 24(3):266-70. · 1.16 Impact Factor
