Septic arthritis of acromioclavicular (AC) joint is a rare entity. It is generally seen in patients who are immunocompromised. Only 15 cases have been reported till now, with only one case series of 6 patients. We report a case of septic arthritis of AC joint in an immunocompetent child. A 9 years old girl presented with history of pain in left shoulder for 4 days associated with fever. No history suggestive of any immunocompromised state was complained. On local examination, a swelling of around 3 cm in diameter was found over left AC joint region with raised local temperature, tenderness on palpation and positive response in fluctuation test...

In juvenile idiopathic arthritis (JIA), imaging is increasingly used in clinical practice. In this paper we discuss imaging of the knee, the clinically most commonly affected joint in JIA. In the last decade, a number of important steps have been made in the development of imaging outcome measures in children with JIA knee involvement. Ultrasound is undergoing a fast validation process, which should be accomplished within the next few years. The validation processes of MRI as an imaging biomarker for clinical trials in the JIA knee are at an advanced stage, with important data available on the feasibility, reliability and validity of the Juvenile Arthritis MRI Scoring system...

Inflammatory arthritis is characterized by chronic inflammation in the synovium, associated with degradation of cartilage and erosion of juxta-articular bone. The bone loss and joint destruction mediated by aberrant immunological responses resulting in proinflammatory cytokine release and various immune cell activation are known as osteoimmunology. Areas covered: A structured literature search including Medline and PubMed, Cochrane meta-analyses and abstracts of international congresses was performed to review joint damage in inflammatory arthritis in terms of pathogenesis, novel imaging assessment and prevention...

Ultrasound is becoming more prevalent as physicians gain comfort in its diagnostic and therapeutic uses. It allows for both static and dynamic evaluation of conditions and assists in therapeutic injections of joints and tendons. Proper technique is necessary for successful use of this modality. Appropriate coding for physician reimbursement is required. We discuss common wrist and hand pathology for which ultrasound may be useful as an adjunct to diagnosis and treatment and provide an overview of technique and reimbursement codes when using ultrasound in a variety of situations...

BACKGROUND: A continuous adductor canal block provides analgesia after surgical procedures of the knee. Recent neuroanatomic descriptions of the thigh and knee led us to speculate that local anesthetic deposited in the distal thigh close to the adductor hiatus would provide superior analgesia compared to a more proximal catheter location. We therefore tested the hypothesis that during a continuous adductor canal nerve block, postoperative analgesia would be improved by placing the perineural catheter tip 2-3 cm cephalad to where the femoral artery descends posteriorly to the adductor hiatus (distal location) compared to a more proximal location at the midpoint between the anterior superior iliac spine and the superior border of the patella (proximal location)...

The morphology of the pretendinous cord in Dupuytren's disease is poorly described in vivo and especially with respect to recurrence after treatment. This prospective study was designed to describe the morphology of Dupuytren's cords by ultrasound and to identify possible correlation between the ultrasonographic characteristics of these cords and the clinical outcomes two years after treatment. Thirty-nine patients with a contracture of at least 20° in the metacarpophalangeal (MCP) joint, who were scheduled for local treatment by either injectable collagenase clostridium histolyticum (CCH) or percutaneous needle fasciotomy (PNF), were examined by ultrasound...

This paper examines the effect of ultrasonic vibration (USV) on grain size and interrupted porosity in Gas Tungsten Arc (GTA) spot-welded copper. Grain size was refined by perpendicularly attaching a transducer to the welded sheet and applying USV to the weld pool for a short time (0, 2, 4, and 6 s) in addition improvements to the degassing process. Results illustrate a significant reduction of grain size (57%). Notably, USV provided interaction between reformations (fragmentation) and provided nucleation points (detaching particles from the fusion line) for grains in the nugget zone and the elimination of porosity in the nugget zone...

INTRODUCTION: Hip dysplasia is characterized by reduced acetabular coverage of the femoral head leading to an increased mechanical load on the hip joint and the acting hip muscles. Potentially, the muscles and tendons functioning close to the hip joint may present with overuse-related ultrasonography findings. The primary aim was to report the prevalence of muscle-tendon-related abnormalities detected by ultrasonography in 100 patients with symptomatic hip dysplasia. The secondary aim was to investigate correlations between muscle-tendon-related abnormalities detected by ultrasonography and clinically identified pain related to muscles and tendons...

BACKGROUND: Adductor canal block (ACB) is a peripheral nerve blockade technique that provides good pain control in patients undergoing total knee arthroplasty which however does not relieve posterior knee pain. The recent technique of an ultrasound-guided local anesthetic infiltration of the interspace between popliteal artery and the capsule of posterior knee (IPACK) has shown promising results in providing significant posterior knee analgesia without affecting the motor nerves. MATERIALS AND METHODS: A prospective study was conducted from September 2016 to March 2017 in a total of 120 patients undergoing unilateral total knee arthroplasty...
