Background:

Fracture of the distal end of the femur are rare, with the litera-

ture reporting a prevalence of 0.5% of all fractures. Incidence rates of distal

femur fractures has only been reported in a small number of studies with the

most resent reporting an overall incidence during a one-year period (2010-

2011) from an adult and well-defined population in Scotland as 7.0/100,000/

year. The literature lacks recent epidemiology studies of the incidence, trauma

mechanism and fracture classification of distal femur fractures.

Purpose / Aim of Study:

To provide up-to-date information concerning the

incidence of distal femur fractures in a large and complete population and to

report on the distribution of fracture classification, trauma mechanisms, and

patient baseline demographics

Materials and Methods:

Retrospective reviews of clinical and radiological re-

cords were performed on distal femur fractures in the Northern Region of Den-

mark between 2005 and 2010.

Findings / Results:

A total of 293 patients were treated for 302 distal femur

fractures. The mean age for males was 44.0 (26.8SD) years, and for females

71.6 (24.0SD) years. The gender distribution was 33.4% males and 66.6% fe-

males. The overall incidence of distal femur fractures was 8.7/100,000/year.

After the age of 60 years a rapid increase in the incidence of distal femoral frac-

tures was observed for both genders with a large female predominance. Low

energy injuries were the most common mode of injury in both genders (97%),

with approximately 61% being the result of a fall from standing height. AO clas-

sification type A was the most common of all fractures (38.6%).

Conclusions:

This study shows an incidence of 8.7/100,000/year of distal fe-

mur fractures. After the age of 60 years a rapid increase in the incidence of dis-

tal femoral fractures was observed for both genders with considerable female

predominance.
