[Evaluation and prognosis of changes in the femur end of the hip in hip dislocation].

Long-term observations proved the necessity of careful control of the development of femur head epiphysis in case of dislocated hip joint. The occurrence of femur head necroses can be greatly reduced by a sparing functional treatment. Endogenously conditioned constructive disturbances, which can be found in 5 to 7 p.c. of all cases, have to be clearly distinguished from head necroses.
