The philosophy of the PFNA blade with better fixation through an increased implant-bone-interface and smaller cross-section, compaction of cancellous bone as well as an antirotational fixation, seems to show advantages compared to the double screw system of the PFN.
There are many cases in the literature that describe atypical femur fractures under antiresorptive therapy. Other localizations of fractures of this genesis, especially if occurring bilaterally, are rare. This case reports about the diagnosis, treatment and process of a 76-year old patient, who within a 4‑month period suffered from bilateral distal tibial shaft fractures, after years of treatment with bisphosphonates, strontium ranelate and denosumab.
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.
