The use of dynamic ultrasonography (US) in diagnosing traumatic and nontraumatic extensor tendon dislocations in fingers of three subjects is reported. Dynamic US of the clenched fist in two patients with traumatic injury revealed dislocated but grossly intact tendons surrounded by soft-tissue edema; magnetic resonance (MR) imaging in one patient ...

The complexity of foot and ankle anatomy and function is unique in the musculoskeletal system. Understanding the complex anatomy alone is a daunting task, not to mention transferring that understanding to the two-dimensional planes encountered on imaging studies. When evaluating sports injuries in the foot and ankle, the interpreting radiologist ...

With the advent of imaging advancements there has been renewed interest in the foot and ankle. However, many of the basic functions and biomechanical considerations of the bones, joints, and specialized tissues of the normal and dysfunctional foot and ankle remain unfamiliar to many radiologists. This article focuses on the ...

Many abnormalities seen in the elbow result from trauma, often from sports such as baseball and tennis. Elbow problems are frequently related to the medial tension-lateral compression phenomenon, where repeated valgus stress produces flexor-pronator strain, ulnar collateral ligament sprain, ulnar traction spurring, and ulnar neuropathy. Lateral compression causes osteochondral lesions ...

Dislocation of the flexor hallucis longus tendon is an exceptional occurrence. To our knowledge, this is the first case ever reported of an intermittent dislocation in a 17-year-old woman; she was a synchronised swimmer. She consulted for a right internal retro-malleolar syndrome. Voluntary "snap" was triggered by a mechanism which ...

Connective Tissue (CT) is a ubiquitous component of all major tissues and structures of the body (50% of all body protein is CT), including that of the blood, vascular, muscle, tendon, ligament, fascia, bone, joint, IVD's (intervertebral discs) and skin. Because of its ubiquitous nature, CT is an often overlooked ...

We report a patient with a locked left thumb in association with de Quervain's disease. While bathing her baby 1 month after giving birth a 32-year-old woman suddenly noticed that she could not radially abduct her left thumb. Magnetic resonance imaging showed thickening of the abductor pollicis longus tendon with ...

The most widely used clinical magnetic resonance imaging techniques for the diagnosis of parenchymal disease employ heavily T(2)-weighted sequences to detect an increase or decrease in the signal from long T(2) components in tissue. Tissues also contain short T(2) components that are not detected or only poorly detected with conventional ...

We report a patient with duplicate extensor pollicis longus tendons, who complained of inability to extend the thumb fully because of impingement of the musculotendinous junction of the duplicate tendons. Extension of the thumb recovered completely after Lister's tubercle was excised and the extensor retinaculum was released. Selective windowing with ...

Foot pain is a common cause of equine lameness and there have been significant limitations of the methods available for the diagnosis of the causes of foot pain (radiography, nuclear scintigraphy and ultrasonography). Until recently, magnetic resonance imaging (MRI) in the horse has been limited to examination of cadaver limbs. ...

The importance of enthesitis in the pathogenesis of spondyloarthropathy (SpA) is now well recognized. Several entheses comprise more than simply the insertion site, and they are part of a complex biomechanical organ to resist shear and compression. It is also evident that tendons that wrap around bony pulleys form an ...

Soft-tissue and osseous impingement syndromes of the ankle can be an important cause of chronic pain, particularly in the professional athlete. The main impingement syndromes are anterolateral, anterior, anteromedial, and posterior impingement. These conditions arise from initial ankle injuries, which, in the subacute or chronic situation, lead to development of ...

Osteochondral lesions of the talus are common injuries, especially in the athletic population. Although multiple etiologies exist, lateral lesions have a higher incidence of association with a specific traumatic event. It has been postulated that lateral lesions are produced when the anterolateral aspect of the talar dome impacts the fibula ...

Previous investigators have not found magnetic resonance imaging (MRI) to be helpful in the diagnosis of interosseous-lumbrical tendon adhesions of the hand. We present 2 cases in which preoperative magnetic resonance images correlated with the clinical diagnosis and intraoperative finding of adhesions between the interosseous-lumbrical tendons at the level of ...

This review article discusses new magnetic resonance techniques for imaging collagen containing structures such as intervertebral discs, tendons, and ligaments. The semisolid collagen in tendons and ligaments is not normally demonstrable with magnetic resonance imaging but may be visualized with magic angle imaging and other techniques. This allows these structures ...

Hindfoot pain from tendon pathology is common and seen in a wide range of patients from young athletes to older sedentary individuals. Magnetic resonance (MR) is an excellent technique for imaging tendons and for identifying injuries that can be treated with surgery. MR also demonstrates the presence of bone marrow ...

Foot pain and disability may curtail the performance of simple routine tasks, work-related duties, and athletic activities. Disorders of the plantar fascia are commonly encountered in the diagnostic evaluation of subcalcaneal heel pain. The approach to imaging the ankle and foot has undergone significant amendment with the introduction of magnetic ...

The term "ankle impingement" encompasses a broad range of conditions that are typically post-traumatic and often chronic. Various forms of mechanical impingement can result from synovial proliferation, bone spur formation, or ligamentous scarring and hypertrophy. Since symptoms and physical findings can mimic a variety of disorders, accurate diagnosis may remain ...

As with other parts of the musculoskeletal system, the soft tissues of the foot can be affected by a wide variety of pathologic entities including trauma, congenital abnormalities, infections, and neoplastic disorders. While plain radiographs are usually the initial examination for evaluation of pathology, magnetic resonance imaging (MRI) is critical ...

There are many conditions that have the potential to produce the symptom of pain in the metatarsal and midfoot regions. Pathologic processes that cause pain include post-traumatic disorders, circulatory disorders, arthritides, neuroarthropathy, and conditions that result in a biomechanical imbalance in the foot. Magnetic resonance (MR) imaging is a powerful ...

We present the case of a patient with long-standing rheumatoid arthritis and an acute onset of total dysfunction of the posterior tibial tendon. On MRI, a rupture of the tendon was apparent. Intraoperatively, however, massive tenosynovitis with stricture of the tendon was identified as the cause of posterior tibial tendon ...
Schmid Marius R - - 2002
BACKGROUND: Chronic overload is considered the main cause of patellar tendinitis, but it has been postulated that impingement of the inferior patellar pole against the patellar tendon during knee flexion could be responsible. HYPOTHESIS: The role of the patellar pole in patellar tendinitis can be determined by dynamic magnetic resonance ...
