Evaluation of Metal Artifact Reduction software in Computed Tomography
Introduction: The image quality of computed tomography (CT) can be seriously lowered by metal implants of patients. These implants are known to exert a significant impact on diagnostic accuracy due to artifacts. The current study aimed to assess the usefulness of Metal Artifact Reduction (MAR) software in the reduction of metal artifacts, in comparison to iterative rec...
متن کاملWear Reduction in Total Ankle Arthroplasty Using Highly Crosslinked UHMWPE
Introduction: Bearing couples within total ankle arthroplasty (TAA) typically utilize cobalt chromium alloys articulating on ultrahigh molecular weight polyethylene (UHMWPE). Articulation of these surfaces during in vivo loading can generate UHMWPE wear particles, which may then result in osteolysis and component loosening [1]. Osteolysis has been observed following TAA in 15-22% of patient pop...
متن کاملChallenges in total ankle arthroplasty.
In the past, total ankle arthroplasty was largely abandoned due to poor survivorship most often caused by loss of bone support. High complication rates were also reported. Despite this, there is renewed interest in ankle arthroplasty and encouraging results are seen in survivorship with midterm follow-up. The procedure, however, remains more challenging than total hip or total knee arthroplasty...
متن کاملHeterotopic ossification after total ankle arthroplasty.
We evaluated the incidence of heterotopic ossification following total ankle replacement to determine whether the degree of ossification was associated with the clinical outcome. We evaluated 90 ankles in 81 consecutive patients who underwent total ankle replacement, and heterotopic ossification was assessed according to proportional involvement of the ankle joint. Correlation analysis was used...
متن کاملSalvage arthrodesis for failed total ankle arthroplasty
BACKGROUND AND PURPOSE Total ankle arthroplasty (TAA) has gained popularity in recent years. If it fails, however, salvage arthrodesis must be reliable as a rescue procedure. We therefore investigated the clinical, radiographic, and subjective outcome after salvage arthrodesis in a consecutive group of patients, and concentrated on the influence of the method of fixation on union rate and on sa...
