For bone metastasis, an endoprosthesis should be used in patients with a good prognosis , which is in contrast to the approach for AFFs. This difference is associated with the fact that bone metastasis is malignant, whereas AFFs are not tumors.
IMN has been generally known as a standard method for displaced AFFs, but delayed union or nonunion is problematic.

For treating the displaced AFF, we could select either IMN or prosthetic reconstruction.
Radiographic findings of the patient were found to be consistent with AFF and she was admitted to the physical medicine and rehabilitation clinic.
AFF related with BPs usage is well defined in the literature and the risk of AFF increases with the prolonged therapy.
As the assays were carried out after fracture, increased levels of bone turnover markers have been reported in AFF cases in the literature (14).
In the literature, the treatment of AFF is based on post-fracture approaches and there are few studies on incomplete AFF treatment (16).
AFF are one of the adverse events associated with long-term use of BPs.
