Acetabular and pelvic fracture accounts for 1.5% of fractures in adults and 2-5% of fractures requiring hospital admission. Several national-level epidemiological studies have been conducted outside France, but French national data are not known. We therefore assessed all patients admitted for acetabular or pelvic fracture in France between 2006 and 2016. The study objectives were: 1) to determine incidence of acetabular and pelvic fracture, 2) to determine progression in incidence between 2006 and 2016, and 3) to determine progression in treatment. Incidence of acetabular and pelvic fracture in France is increasing. The following data for the period 2006-2016 were collated from the French national health insurance (CPAM: Caisse Primaire d’Assurance Maladie ) database: gender, age, type of treatment, and geographical distribution by administrative area ( Département ). Two-tailed Student tests were used for comparison of means for numerical variables between independent samples; linear regression was used to analyze correlations; and the Chi 2 test was used to compare percentages of categoric variables. There were 32,614 acetabular and 164,694 pelvic fractures, with male predominance for the acetabulum and female predominance for the pelvis. Mean age at acetabular fracture was 66 ± 22 years (range, 1-108 years), and 74 ± 20 years (range, 1-112 years) for pelvic fracture. The rate of acetabular fracture increased to 3,301 in 2016 from 2,316 in 2006, with a strong increase in the rate of pelvic fracture, to 18,902 in 2016 from 10,806 in 2006. Incidence of acetabular fracture per 100,000 increased from 3.67 in 2006 to 4.95 in 2016, and from 17.06 to 23.18 in over-75 year-olds. Incidence of pelvic fracture per 100,000 increased from 17.1 to 28.33, and from 129.30 to 210.69 in over-75 year-olds. Linear regression predicts incidence per 100,000 of 5.9 for acetabular fracture and of 41 for pelvic fracture by 2030 in young subjects and 32 and 309 respectively in over-75 year-olds. Management was surgical for acetabular f...
