BACKGROUND: Bisphosphonates reduce the overall risk of fractures among patients with osteoporosis, and this beneficial effect is long-lasting. However, since bisphosphonates inhibit bone remodeling, they may enhance the formation and propagation of micro-cracks over time and patients may therefore be prone to atypical fatigue fractures, mainly in the subtrochanteric region and femoral shaft. OBJECTIVES: To present two cases of subtrochanteric fractures related to bisphosphonate treatment, and review the current literature. CONCLUSIONS: Despite the overall beneficial effect of bisphosphonates, further research is required to prevent this significant complication.
