Primary myelofibrosis is a chronic clonal stem cell disorder that results in a build-up of marrow fibrosis and dysfunction, hypermetabolic states, and myeloid metaplasia. The clinical and radiological consequences can be quite diverse and range from the manifestations of osteosclerosis and extramedullary haematopoiesis to thrombohaemorrhagic complications from haemostatic dysfunction. In addition, there is the challenge of identifying less well-recognised sites of extramedullary haematopoiesis and their site-specific complications. The intent of this article is to illustrate the spectrum of primary myelofibrosis as declared though multimodality imaging, with examples of both common and rarer disease manifestations.
Scaphoid non-union develops in 10% of scaphoid fractures. There is sparse literature on fixation methods other than screws. We compared union rates following fixation of scaphoid non-union using screw fixation and a novel method of plate fixation. Retrospective study. Union rates were assessed at 3 months post-operatively by a musculoskeletal radiologist. 15 patients underwent screw fixation and 15 underwent plate fixation. 86% union rate with screw fixation and 72% plate fixation united. There was no significant difference. Screw fixation and plate fixation in our institution both provide union rates that are consistent with the literature.
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.
