The analysis of complications after surgery with use of various fixation devices testifies to the need of conducting studies aimed at the definition of indications to the choice of fixation device for treatment of distal femur fractures. In the paper the comparative data of surgical treatment results of patients with distal femur fractures by means of bone fixators with angle stability (Gr. І; n=14) and locking intramedullary rod (Gr. ІІ; n=13) are given. On the basis of results analysis indications for the choice of fixation device are formulated and grounded.
