Post therapeutic lower extremity rotational profiles in children with DDH.
OBJECTIVE
The purpose of this study was to investigate post-therapeutic lower extremity rotational profiles in children with developmental dislocation of the hip (DDH), the differences between these values and those of normal children, and the relationship between these differences and clinical and radiological results.


METHODS
In 82 lower extremities of 64 patients, the foot-progression angle was measured clinically and the transmalleolar axis angle photographically, and hip rotations and thigh-foot angle were measured both clinically and photographically. The data obtained were compared with Staheli's data for normal children. In addition, clinical and radiographic data were compared within subgroups and with Staheli's data. Student's t-test and one-way ANOVA were used for statistical evaluation.


RESULTS
The medial rotation of the hip, the average clinical value was 44.66 masculine, and the photographic value was 42.28 masculine. Lateral rotation of the hip, the average clinical value was 38.01 masculine, and the average photographic value was 37.29 masculine. Thigh-foot angle, his angle was clinically 8.23 masculine and photographically 9.68 masculine. Angle of the transmalleolar axis, the photographic average was 21.59 masculine. Foot-progression angle, the clinical average was 10.70 masculine. It was determined that the lower extremity rotational profiles of children with DDH treated after walking did not differ from those of normal children, but that the internal and external hip rotations of McKay type III and IV patients were below those of normal children and of McKay type I and II patients.


CONCLUSIONS
Lower extremity rotational profiles in children with DDH who received appropriate treatment were the same as those for normal children.
