<b>Background:</b> Sonographic techniques are simple and safe. The utility and clinical value of dynamic sonographic evaluation of the glenohumeral joint in infants with brachial plexus injury (BPBI) has been described since the late 1990's. However, this technique remains an underutilized tool in most imaging practices. Brachial plexus injury during the birthing process can lead to glenoid dysplasia, posterior shoulder subluxation and significant morbidity if left untreated. Imaging evaluation of the degree of deformity is paramount to guide clinical treatment and the follow-up of complicated cases. Imaging techniques include MRI, CT and US. Shoulder ultrasound provides a dynamic, noninvasive method of evaluation. It has also been our experience that this imaging technique can be mastered by the Sonographer and supported with accurate interpretation by the Radiologist. <b>Purpose:</b> Describe the imaging features of glenohumeral joint dysplasia due to BPBI with emphasis on ultrasound technique. Review step-by-step dynamic sonographic evaluation of the glenohumeral joint in BPBI with emphasis on correct positioning of the patient to ensure consistency and reproducible quality imaging. Improve both confidence and independent evaluation of patients through this presentation by the sonographer. Read More

Chronic nonbacterial osteomyelitis (CNO) is an aseptic auto-inflammatory condition that affects children and presents with insidious bone pain. Children present with a variable clinical spectrum of disease with either unifocal or multifocal pain and acute (duration &lt; 6months) or chronic (&gt;6 months) symptoms. The disease course may be recurrent. In some cases, patients endure multiple lesions over a course of exacerbations and remissions. Bone lesions are often in symmetrical regions. Interestingly, clinically asymptomatic bone lesions are discovered during the imaging evaluation. Patient symptoms and clinical course may mimic other diseases, making CNO often difficult to diagnose with a consequent delay in diagnosis. Children with CNO may also develop arthritis and demonstrate similar cytokine profiles with children with juvenile idiopathic arthritis (JIA), suggesting at least a partial common disease pathway.
