Differentiational correction of muscles of external rotators of femur in congenital dislocation

External rotatory contracture in hip joint appears in some cases in the process of correction of the proximal part of femur. Incomplete and low dislocations of femur are stated to be characterized by absolute shortening of short external rotators and high forms of dislocations — by shortening of middle gluteal muscle. The methods of correction of the length of these muscles in the process of treatment of the dislocation of femur are suggested. The comparative analysis of treatment results of the congenital dislocation of femur in 159 persons by the methods, developed by the authors and traditional methods is presented. The positive result of the treatment is received in 95,4% patients.
