Muscle denervation results from a variety of causes including trauma, neoplasia, neuropathies, infections, autoimmune processes and vasculitis. Traditionally, the diagnosis of muscle denervation was based on clinical examination and electromyography. Magnetic resonance imaging (MRI) offers a distinct advantage over electromyography, not only in diagnosing(More)
OBJECTIVE The purpose of this study was to use CT to determine the presence of radiologic parameters associated with cam and pincer femoroacetabular impingement (FAI) in a young population without symptoms. MATERIALS AND METHODS A retrospective review of 50 patients (age range, 20-40 years) with no current or previous hip disorder who underwent CT of the(More)
The double posterior cruciate ligament (PCL) sign is seen on a midline sagittal MR image of the knee as a low-signal-intensity linear band paralleling the antero-inferior part of the PCL. Although the sign has a high specificity for a displaced bucket-handle tear of the medial meniscus, it can be mimicked by several normal and abnormal structures in the(More)
The initial diagnosis of an “ankle sprain” is not always correct. Prolonged pain, swelling and disability sufficient to limit the activity and refractory to treatment following an ankle injury are not typical of an ankle sprain and should alert the clinician of the possibility of an alternative or an associated diagnosis. There are several conditions that(More)
To look for any association between oedema in the superolateral portion of the infrapatellar fat pad and patellar maltracking. We compared two groups of knee MRI with regard to five patellar maltracking parameters. The first group included 100 knees with evidence of oedema in the superolateral aspect of the infrapatellar fat pad (the study group). The(More)
Background and Purpose—The increased risk of stroke and thromboembolism in atrial fibrillation (AF) may be related to a prothrombotic or hypercoagulable state, with abnormalities of hemostasis and platelet activation. To investigate the role of platelets in AF and the influence of antithrombotic therapy, we developed and then applied a new assay to detect(More)
We report a case of complete stress fracture of the ulna and stress reaction of the radius resulting from the use of crutches in an overweight patient with severe lower extremity arthritis. Plain radiograph showed an undisplaced complete fracture of the proximal metaphysis of the ulna. Magnetic resonance imaging (MRI) was performed to exclude a pathological(More)
Pericardial involvement in dermatomyositis is rare and usually asymptomatic. In many instances, a diagnosis of pericardial involvement is not found until autopsy. Renal failure associated with connective tissue disorders can result in or potentially exaggerate pericardial inflammation. We report an unusual case of high-density pericardial effusion in a(More)
Most acute ankle injuries involve the lateral ligament complex. There are several other structures that can be injured during acute ankle trauma and therefore can be responsible for the patient's acute presentation or for continuing pain. Some of these injuries are less common than others and thus can be more frequently missed during the initial patient(More)
