Chronic foot pain is a common and often disabling clinical complaint that can interfere with a patient's routine activities. Despite careful and detailed clinical history and physical examination, providing an accurate diagnosis is often difficult because chronic foot pain has a broad spectrum of potential causes. Therefore, imaging studies play ...

Many patients present to their physician's office with the chief complaint of pain at the Achilles tendon. This review discusses the pathology, diagnosis, and treatment of Achilles tendinopathy. Achilles tendinopathy is generally caused by chronic stress to the tendon, leading to a defective arrangement of collagen fibers in the Achilles ...

We report a case of the flexor digitorum profundus tendon rupture of the little finger, which was predisposed by an anatomic variation of the tendon. Intraoperative findings and magnetic resonance imaging of the opposite hand suggested that the flexor digitorum profundus tendons of the ring and the little finger bifurcated. ...

Quadriceps tendon ruptures are an uncommon knee injury. The diagnosis is often complicated by a limited examination secondary to edema and pain, the insensitivity of radiographs, and the unavailability of non-emergent magnetic resonance imaging. A delay in diagnosis and treatment has been shown to cause significant morbidity. A case report ...

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 ...

Eventration of the diaphragm is a rare condition where the muscle is permanently elevated, but retains its continuity and attachments to the costal margins. It is seldom symptomatic and often requires no treatment, but may be confused with a traumatic rupture of the diaphragm. We present a 51-year-old man with ...

Musculoskeletal ultrasound (US) has an increasingly important role in the assessment of spondyloarthritis (SpA) not only for its ability to detect synovial and tendon involvement but also for the accurate imaging of enthesitis, the clinical hallmark feature of SpA. As already known, most cases of enthesitis are subclinical in SpA ...

The characteristic pathological finding in carpal tunnel syndrome (CTS) is noninflammatory fibrosis of the synovium. How this fibrosis might affect tendon function, if at all, is unknown. The subsynovial connective tissue (SSCT) lies between the flexor tendons and the visceral synovium (VS) of the ulnar tenosynovial bursa. Fibrosis of the ...

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 ...
