influence of the mechanical and anatomical changes in the congenital hip dislocation

ABSTRACT

This paper will demonstrate the effect of the anatomical and the mechanical changes which are the cause or the result of a dislocated hip in influencing the treatment of this condition. The contents of this paper are based on observation and a studies made on two hundred and ten hips treated when the deformity was established and covers the Period between Oct 1982 and the end of 1988. The paper demonstrates that two forms of dislocation were encountered. In one, the hip is basically normal, and the changes seen were the result of the malalignment of the joint, while in the other type the hip is abnormal and so the changes that result are the effect of this abnormality. Based on these findings a treatment guide was made to avoid errors encountered, because of an inadequate correction, or a faulty correction which results in serious failures, that require a second or even a third correction, with all the drawbacks of repeated surgeries in this area
