To analyze the surgical results of AO type C distal femoral fractures using locking compression plate.

From February 2006 to June 2008, 14 patients 15 cases were included. Injury mechanisms, combined injuries, radiologic and clinical results and postoperative complications were analyzed.

The mean age was 59.6 (30~77) years. The mean follow up period was 25 (12~40) months. AO types were 3 of C1, 5 of C2 and 7 of C3. Injury mechanisms were 9 of traffic accident, 5 of slip down and 1 of fall from a height. Four cases were combined with other extremity injuries or fractures. The mean radiologic union was obtained at postoperative 15 (13~20) weeks. The mean Neer's functional score was 74.2 (58~97); 3 of excellent, 5 of satisfactory and 7 of unsatisfactory. Postoperative complications were 2 of infection and 1 of nonunion. There were no mechanical failures or fixation loss with locking compression plate at the final follow up.

Internal fixation using locking compression plate for AO type C distal femoral fractures provided excellent fixations. At the final follow up, the clinical results were variable. The affecting factors on the final results seemed to be joint congruencies after anatomical reduction and active rehabilitation.
