We report on an 80-year-old female patient with osteoporotic collapse of the L1 vertebra who developed absolute stenosis of the spinal canal. During preoperative vertebra augmentation with PMMA (polymethylmethacrylate), pulmonary embolism developed due to perivertebral leakage of acrylic cement. According to the literature, leakage of PMMA during (percutaneous) vertebroplasty is a more frequent complication than assumed so far. In view of the favorable prognosis of osteoporotic vertebral compression fractures with noninvasive management, we emphasize the need for clear and individual indications and adequate technical settings.
This report describes the procedures applied to remove a metal foreign body retained inside the ulnar nerve in the distal humerus of a 49-year-old patient. Exemplified by an unfavorable primary treatment this article presents the first description of removal of an foreign body retained within a nerve whereby emphasis is placed on the problems associated with the preoperative and intraoperative localization of the foreign particle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
