Ultrasound abnormalities in septic arthritis are associated with functional outcomes.

Objectives: To describe the ultrasound abnormalities seen in septic arthritis and to assess their associations with clinical, biological, and radiological outcomes.

Methods: We prospectively included 34 patients with septic arthritis of a native joint (knee, n=19; shoulder, n=6; hip, n=4; ankle, n=3; or wrist, n=2). Ultrasonography was performed to record synovial-membrane thickness and vascularity, joint effusion, and abnormalities of adjacent soft tissues, at baseline then 4days, 2weeks, and 3months later.

Similar outcome despite slight clinical differences between lumbar radiculopathy induced by lateral versus medial disc herniations in patients without previous foraminal stenosis: a prospective cohort study with 1-year follow-up.

Background Context: It has been claimed that lumbar radiculopathy induced by foraminal disc herniations had poorer outcome and different clinical features, including: 1-more progressive onset, but shorter duration between the first sign and request of medical care; 2-more severe radiculopathy; 3-less frequent/severe back pain; 4-less limitation of straight leg raising (SLR); 5-more frequent neurologic deficiencies; 6-poorer outcome.

Purpose: To check whether this still holds true when including only patients without other reasons for foraminal stenosis, that is, whether patients with medial disc herniations had different features and outcome than those with more lateral disc herniations.

Study Design: All patients hospitalized to treat a lumbar radiculopathy within a 6-month period in two French rheumatology units in 2012 were included in this prospective study each time computed tomography scan or magnetic resonance imaging had already been performed and showed clear disc bulging/herniation but no features of medial or lateral spinal stenosis.

Three-dimensional versus two-dimensional ultrasonographic assessment of peripheral enthesitis in spondylarthritis.

To compare the intra- and interobserver reliability of three-dimensional (3D) volumetric versus conventional two-dimensional (2D) power Doppler ultrasonography (US) in the assessment of peripheral enthesitis in spondylarthritis (SpA). Sixteen patients with SpA according to ASAS criteria were included. Two rheumatologists (one experimented in musculoskeletal US (sonographer 1) and one beginner (sonographer 2)) performed independently a 2D US scoring of the enthesis using the Madrid Sonographic Enthesis Index score followed by a 3D acquisition of the same entheseal sites.
