The treatment of DDH with the method of Hoffmann—Daimler is based on the following principal: By placing the hip in flexion, the resultant L force is redirected and the femoral head is pulled gradually caudally and causes it to travel back to the acetabulum .
reduction forces acting on hip
Simultaneously all anatomic changes gradually fully reverse25 where at the end the femoral head reduces (phase A). These principal is the same for all successful functional treatments, like Pavlik method.The hip capsule if we want to give an example behaves as the mouth of a boa where it can distentted way far of the original size …….

By placing the hip in flexion, the resultant L force is redirected and the femoral head is pulled gradually caudally and causes it to travel back to the acetabulum (fig2 b). Simultaneously all anatomic changes gradually fully reverse25 where at the end the femoral head reduces (phase A).
