The authors make distant evaluation of functional and radiological outcomes after operative treatment of peritrochanteric femur fractures using dynamic hip stabilizer (DSB) from perticulary to take into consideration complications and failures. It was done basing on clinical material of 1998-2005 years. 142 patients were included to the study, 89 women (62.7%) and 53 men (37.3%), aged between 53-97 years (average 77 years). These patients make up 72.5% of all treated because of peritrochanteric femur fractures. Boyd and Gryffin classification was used for evaluation of type of fracture, Harris criterions was used for evaluation of functional outcomes and Golec's criterions was used for evaluation of radiological outcomes. Obtained outcomes allow confirm usefulness of DSB for treatment of type I and II according to Boyd and Griffin classification. Poor outcomes were obtained in type III and IV.
