This study evaluated the ability of routine 1.5-T MRI scans to visualize the anterolateral ligament (ALL) and describe its path and anatomic relations with lateral knee structures. Thirty-nine 1.5-T MRI scans of the knee were evaluated. The scans included an MRI knee protocol with T1-weighted sequences, T2-weighted sequences with fat saturation, and proton(More)
PURPOSE To evaluate the epidemiology of injuries and abnormalities of the anterolateral ligament (ALL) by magnetic resonance imaging (MRI) in cases of acute anterior cruciate ligament (ACL) injury. METHODS MRIs of patients with acute ACL injury were evaluated. Acute injuries of the ACL were considered in cases in which the patient reported knee trauma(More)
OBJECTIVE To evaluate the presence of the anterolateral ligament (ALL) of the knee in magnetic resonance imaging (MRI) examinations. METHODS Thirty-three MRI examinations on patients' knees that were done because of indications unrelated to ligament instability or trauma were evaluated. T1-weighted images in the sagittal plane and T2-weighted images with(More)
BACKGROUND Anatomic and magnetic resonance imaging (MRI) studies have recently characterized the knee anterolateral ligament (ALL). So far, no study has focused on confirming whether the evaluated MRI parameters truly correspond with ALL anatomy. PURPOSE To assess the validity of MRI in detecting the ALL using an anatomic evaluation as reference. STUDY(More)
BACKGROUND Recent anatomical studies have identified the anterolateral ligament (ALL). Injury to this structure may lead to the presence of residual pivot shift in some reconstructions of the anterior cruciate ligament. The behavior of the length of this structure and its tension during range of motion has not been established and is essential when planning(More)
STUDY DESIGN Prospective cross-sectional study. OBJECTIVE To analyze the association of tomographically identified axial gouty lesions with clinical and laboratory characteristics. SUMMARY OF BACKGROUND DATA Axial gout might be more common than previously thought. The true relationship of these lesions to symptoms or other gout-associated features is(More)
OBJECTIVE To evaluate the effect of complete absence of muscle contractions on normal human cartilage in the presence of joint motion. METHODS Patients with complete acute spinal cord injuries were enrolled. All patients underwent magnetic resonance imaging (MRI) on both knees as soon as their medical condition was stable and at six months after the(More)
Posterior cruciate ligament avulsion fracture from its tibial insertion is a rare pathology in children. It is usually caused by high-energy traumas and its diagnosis is not always easy. Late diagnosis leads to late treatment, which can result in suboptimal results. We present a case of a 13-year-old boy hit by a car, who had a delay in diagnosis and(More)
Few studies have used MRI to identify the ALL. As it was shown that it is not possible to precisely characterize this ligament in all examination, it is important to identify concomitant lesions that can help in diagnosing ALL abnormalities. It is important to characterise this injury due to its association with anterolateral knee instability. Thus, the(More)
INTRODUCTION Purposes of this study were: evaluate complications and length of stay of patients admitted with diagnosis of ischemic stroke (IS) in the acute or subacute phase, in a general Neurology ward in São paulo, Brazil; investigate the influence of age, risk factors for vascular disease, arterial territory and etiology. METHODS Data from 191 IS(More)
