From October 1995 to December 2006, the authors used NITINOL staples for 65 osteosyntheses of the scaphoid. Indications were 15 unstable fractures, 47 nonunions, and three partial necroses. 61 out of 65 scaphoids healed without further surgery, three of the 61 patients showed a delayed healing. Two of the four nonunions were related to the use of the NITINOL staples. Seven staples were removed, one for loosening. NITINOL shape memory staples have proven to be very helpful for osteosynthesis in fractures and nonunion of the scaphoid, if the prerequisites are given for their use.
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.
