OBJECTIVE: Ankle sprain severity is difficult to assess initially in the emergency department, yet it governs treatment decisions. Ultrasonography readily shows fluid present in the talocrural joint, which is difficult to assess by physical examination. The purpose of this study was to evaluate the prevalence of ultrasonographic talocrural joint effusion ...

Ultrasonography (US) of the elbow is an increasingly utilized modality for a variety of diagnoses. US is advantageous in many cases because of the ability to perform a dynamic examination while obtaining patient feedback. Furthermore, US is cost effective, widely available, and beautifully demonstrates superficial soft tissue structures. Finally, US ...

Entheses are sites where tendons, ligaments, joint capsules or fascia attach to bone. Inflammation of the entheses (enthesitis) is a well-known hallmark of spondyloarthritis (SpA). As entheses are associated with adjacent, functionally related structures, the concepts of an enthesis organ and functional entheses have been proposed. This is important in ...

Ankle impingement syndromes are categorised according to their anatomical site around the tibiotalar joint. Anterolateral, anterior and posterior ankle impingement has been extensively described in the orthopaedic and radiology literature with more recent studies describing posteromedial and anteromedial impingement. This article aims to demonstrate the potential spectrum of imaging findings ...

Contracture of the gastrocnemius musculature is a prevalent finding in the setting of foot and ankle pathology. Tightness of the posterior musculotendinous structures in the leg limits ankle range of motion and affects an equinus posture of the foot. Increased contact pressures are generated in the plantar foot with weightbearing. ...

For extramedullary tibial alignment in total knee arthroplasty, it is important to localize the center of the ankle mortise. Malpositioning of alignment jigs can produce varus or valgus implantation and can lead to inferior clinical and radiologic outcomes. In a cadaver study, we investigated the accuracy of palpable tendons as ...

Tuberculosis involving the soft tissue from adjacent bone or joint is well recognized. However, primary tuberculous pyomyositis, tuberculous bursitis, and tuberculous tenosynovitis are rare entities constituting 1% of skeletal tuberculosis. Tuberculous tenosynovitis involves most commonly the tendon sheaths of the hand and wrist, and tuberculous bursitis occurs most commonly around ...
