Core Tip	This retrospective study shows that approximately one in ten elderly patients sustaining a proximal femoral fracture (PFF) will later experience a contralateral fracture. The second fracture frequently reproduces the same fracture pattern as the first, and multivariate analysis confirms that the initial fracture type is an independent predictor of the contralateral fracture pattern. Most second fractures occur within a 2-5 years interval after the first event. These findings suggest that patients with a first PFF represent a clearly identifiable high-risk population in whom targeted secondary prevention strategies should be prioritized.
