Significance of endogenic factors in the location of fractures of the proximal femur.

The significance of endogenic factors in the localization of the fractures of the proximal femur was studied in 373 patients, with 402 fractures. A statistically significant relation was found between muscular disturbances of the affected leg and trochanteric fractures, while the incidence of femoral neck fractures was high in osteoporotic but physically active individuals.
