PURPOSE To assess magnetic resonance (MR) imaging findings after acute lateral patellar dislocation (LPD) with emphasis on the medial patella restraints and to describe a medial patellar impaction deformity. MATERIALS AND METHODS Knee MR images obtained within 8 weeks after LPD were evaluated for medial retinacular and medial patellofemoral ligament(More)
BACKGROUND The goals of this study were to (1) define the epidemiology of acute patellar dislocation, (2) determine the risk of subsequent patellar instability episodes (subluxation and/or redislocation) during the study period, and (3) identify risk factors for subsequent instability episodes. STUDY DESIGN Prospective cohort study. METHODS The authors(More)
Anterior knee pain is a common symptom, which may have a large variety of causes including patellofemoral pathologies. Patellofemoral maltracking refers to dynamic abnormality of patellofemoral alignment and has been measured using plain film, computed tomography (CT) and magnetic resonance imaging (MRI) using static and kinematic techniques. Patellar(More)
INTRODUCTION An increase in the incidence and severity of acute osteoarticular infections in children was perceived after the emergence of community-associated methicillin-resistant Staphylococcus aureus (MRSA) in our community. This study was performed to describe changes in the epidemiology and clinical features of acute osteoarticular infections. (More)
PURPOSE To assess magnetic resonance (MR) imaging signs and overall accuracy of MR imaging for detection of osseous invasion by soft-tissue sarcoma, with histopathologic correlation as the reference standard. MATERIALS AND METHODS Preoperative MR images (1.5 T, transverse and longitudinal planes, T1 and T2 weighted) of 56 osseous sites in 51 patients who(More)
Localization and pathologic diagnosis of optic nerve tumors have been greatly improved by high resolution computed tomography and magnetic resonance imaging. Radiologic differentiation of the most common tumors of the optic nerve (meningioma and glioma) can be made by using these new imaging modalities. Early diagnosis of optic nerve lesions has resulted in(More)
RESEARCH DESIGN AND METHODS — We studied 36 consecutive patients who presented to the Diabetic Foot Clinic over the last 5 years with a red, hot swollen foot and a skin temperature 2°C compared with the same site on the contralateral foot and who had no previous treatment. There was no evidence of any skin breakdown or ulceration. Foot skin temperatures(More)
The objective of this study was to determine whether radiographic damage is different in British black African patients with rheumatoid arthritis compared to Caucasian patients. Data on demographics, disease- and disability-related variables were obtained from all black African patients and their age-, gender- and disease-duration-matched Caucasian(More)
