Osteoporotic Distal Femur Fractures: An Overview

BackgroundDistal femur fractures in geriatric patients present a significant challenge due to age-related factors, including osteoporosis, comorbidities, and diminished functional reserve. These injuries have high morbidity and require nuanced management strategies to optimize outcomes. In the current chapter, we have reviewed the challenges associated with these intricate injuries and the potential solutions for their favorable outcomes.MethodWe reviewed the published literature on epidemiology, pathophysiology, clinical presentation, and current treatment modalities for distal femur fractures in the elderly population, with a focus on advances in surgical techniques, rehabilitation strategies, and outcomes.DiscussionOperative treatment remains the mainstay, tailored to fracture patterns, patient comorbidities, and bone quality. Locking plates offer strong fixation in osteoporotic bone, while intramedullary nails, especially the newer generation ones, provide better biomechanical stability for unstable fracture types. Total knee replacement and distal femur replacement is a viable option in severe cases with comminution or poor bone quality.ConclusionDistal femur fractures in the elderly are complex injuries with high morbidity and mortality. Early surgical intervention, optimized postoperative care, and a focus on addressing osteoporosis are key to improving outcomes and minimizing the long-term impact of these fractures on the vulnerable population. Favorable fracture healing can be achieved with plates, nails and their combinations as long as they are judiciously used.
