PURPOSE To determine the accuracy of magnetic resonance (MR) arthrography in assessing the anterolateral recess of the ankle. MATERIALS AND METHODS Thirty-two patients with chronic ankle pain prospectively underwent gadolinium-enhanced MR arthrography of the tibiotalar joint. All underwent clinical examination and were included if anterolateral(More)
BACKGROUND The functional outcomes following ankle arthrodesis are not known. The purpose of the present study was to compare the intermediate-term clinical results for a group of patients in whom an ankle arthrodesis had been performed with use of modern surgical techniques with the findings for a group of healthy gender and age-matched controls on the(More)
BACKGROUND Surgical treatments for end-stage ankle arthritis include total ankle replacement and ankle arthrodesis. Although arthrodesis is a reliable procedure, ankle replacement is often preferred by patients. This prospective study evaluated intermediate-term outcomes of ankle replacement and arthrodesis in a large cohort at multiple centers, with(More)
OBJECTIVE To retrospectively review the outcomes of percutaneous flexor tenotomies of diabetic claw toes with ulcers or pending ulcers. METHODS We undertook a retrospective chart review between January 1999 and June 2005 to identify those patients who had undergone a percutaneous flexor tenotomy for diabetic claw toe deformities. We identified 34 toes in(More)
BACKGROUND Current operative outcome scales are based on pain and function, such as the Ankle Osteoarthritis Scale (AOS). Outcomes based on patient expectation and satisfaction may be more useful. The purpose of this prospective cohort study was to evaluate associations between patient expectation, satisfaction, and outcome scores for ankle fusion and total(More)
BACKGROUND Patient-reported outcome measures are increasingly used evaluating clinical care. Many measures used to assess operative hindfoot interventions vary in content, and some have not been psychometrically validated in this population. The purpose of this study was to compare measurement properties of 6 lower-extremity patient-reported outcome(More)
UNLABELLED Gait analysis, the systematic study of human walking, is a field that has been studied for well over 100 years. With the technological and scientific advancements of the last several decades, there has been substantial improvement in our understanding of the mechanics of human walking. Particularly important has been the advancement in(More)
BACKGROUND End-stage ankle arthrosis is one of the leading causes of chronic disability in North America. Information on this condition is limited. The amount of pain and the reduction in health-related quality of life and function have not been quantified with use of universal outcome measures. The purpose of the present study was to compare the extent of(More)
The "hepatic arterial buffer response" hypothesis states that the hepatic artery is not controlled by liver parenchymal cell metabolic activity. Bile salts stimulate liver metabolism (elevate bile formation) and dilate the hepatic artery. The present data show that the vascular and metabolic effects in cats anesthetized with pentobarbital sodium are(More)
