Abstrakt:	Objective  The present study aims to describe outcomes from a series of surgically treated patients with atypical femoral fracture due to bisphosphonates use, in addition to correlate the time of previous medication use with fracture consolidation time, and to compare the consolidation time of complete and incomplete fractures. Methods  This is an observational, retrospective study with 66 patients diagnosed with atypical femur fractures associated with chronic bisphosphonates use. The patients underwent orthopedic surgical treatment at a referral hospital from January 2018 to March 2020. Results  All patients were females, with two bilateral cases. Fracture consolidation occurred in all cases, with an average time of 2.3 months and a follow-up time of 5.8 months. The average time of bisphosphonates use was 7.8 years. There was no correlation between the time of previous bisphosphonates use and the time for fracture consolidation. Consolidation time differed in complete and incomplete fractures. Conclusion  Surgical treatment with a long cephalomedullary nail resulted in consolidation in all patients. The consolidation time was longer in complete fractures when compared with incomplete lesions, and there was no correlation between the time of previous bisphosphonates use and the consolidation time . Level of evidence  Level IV, case series. Competing Interests: Conflito de interesses Os autores declaram não haver conflito de interesses. (Sociedade Brasileira de Ortopedia e Traumatologia.
