Epidemiology of acetabular fractures in elderly patients and the effect of various management options on the outcomes. A comprehensive narrative review.

Owing to the expected increase in the world's elderly population (>65 years old), and the concomitant osteoporosis in this particular population, fragility fractures of the pelvis and the acetabulum is becoming a real concern, which could be life-threatening. In the current review, we aimed to discuss the various epidemiological characteristics of geriatric acetabular fractures, management options, and the outcomes. For the review synthesis, we searched PubMed to select the most relevant and updated articles published from various areas and institutions. Geriatric acetabular fractures are mainly caused by trivial trauma, constitute about 1.5%-3% of all skeletal injuries, and showed a 2.4-fold increase over the past three decades. Furthermore, these fractures' associated one-year mortality rate ranges from 14% to 25%. Management options differ largely according to the type and severity of the injury if there is an associated skeletal or non-skeletal injury, and preexisting patient comorbidities. These options could be nonoperative or operative (including surgical fixation and acute total hip arthroplasty), and both carry a specific risk in this vulnerable age group. There is controversy among various reports regarding the best management option leading to better function and health-related quality of life (HRQoL) outcomes. In conclusion, the incidence of acetabular fractures in elderly patients is rising. The decision-making on the best management option should consider the patient's fragility, injury severity, poor bone quality, and multiple medical comorbidities. The outcomes related to function, quality of life, and mortality are comparable between operative and nonoperative management options.
