Abstract: Background: Incidence of distal femur fractures is approximately 37/ one lakh person-years. Distal femoral fractures mainly arise from two different injury mechanisms by high energy trauma and low energy trauma.
Objective: To find out the causes of Non Union of distal femur and progress of such nonunion.
Methodology: Total 35 cases of distal femur fracture nonunion satisfying inclusion and exclusion criteria treated and followed up in post graduate institute of swasthiyog pratishthan, miraj from May 2012 to September 2014 are taken in the study and all patients were followed up according to post-operative follow up protocol.
Results: Among the 35 cases 31 were male and 04 were female. The mean age of case presenting to us at the detection of Non Union was 38.5 years. Symmetrical distribution of cases in the age group from 20-49 years which accounted for 29 cases (82.85%). Right limb was involved in more number of cases. Accidents were noted to be the main cause of primary fractures. Most of the cases had a compound injury initially. Aseptic Non Union was seen in 60% and infected Non Union in 40% of cases. The most common cause of non-union was found to be infection
