Prolonged bisphosphonate (BP) treatment is associated with some complications, such as atypical femoral fractures (AFFs). Recent studies showed
that atypical fractures also occurred in other bones, especially in the atypical fracture of the proximal ulna (AFPU). Although, AFPUs frequently
share the same characteristics of atypical fractures as AFFs, such as fracture configuration and high risk of non-union, there is still limited evidence
of the role of non-operative treatment in AFPU. The aim of the present study was to present an interesting case involving an 80-year-old female
presented with non-displaced AFPU after receiving long-term BP medication and had been treated with a conservative method for 2.5 years, and
to review the literature regarding the available AFPU treatment options. To the best of the authors’ knowledge, the present case report introduced
new insight of the outcome of non-operative treatment for AFPU.
