 Introduction: Atypical femoral fractures are are a special type of femoral fracture in respect to thefracture pattern, anatomical location, low energy trauma. Over recent years, reports have suggested a direct relationship between long–term use of bisphosphonates and the development of such fractures but mechanism is still unclear, the recent increase in reporting of such fractures in patients under long–term usage of bisphosphonates justifies the need for research into the association between the two. Case series: We intend to report three such cases that presented to our institution.All patients presented with the characteristics of atypical femoral fractures which included low energy trauma, anatomical location, transverse or short oblique configuration with a medial spike, no comminution and lateral cortical thickening.patients underwent surgical fixation and were followed–up till union of the fracture. Conclusion: Identifying this specific fracture and treating it with caution is necessary as they tend to take more time to heal in comparison with high energy trauma femoral fracture. Educating physicians and surgeons regarding this type of fracture is of prime importance both in prevention as well as treatment of this type of fracture, which contributes to significant reduction of morbidity and mortality to the patient. careful prescription of bisphosphonates for patients with definite indications and proper monitoring during follow–up would be another justifiable preventive measure.
