[Late results of conservative treatment of perthes disease.].
The objective of the submitted work was to assess the long-term prognosis of Perthes disease. From the originally invited 142 patients 72 attended the check-up examination, complete X-ray documentation was assembled only in 32 patients with 38 affected hip joints. The time interval which had elapsed since the onset of the disease was on average 17 years. The authors evaluated the clinical and X-ray picture of the hip joints and assessed retrospectively the affection of the head according to Catterall's method, incl. signs of a head associated with risk. Treatment provided during the sixties and beginning of the seventies did not meet the principles of modern "containment" therapy. It comprised bed rest, application of a plaster spike and aftertreatment with a Thomas splint. During late check-up examinations Wiberg's angle, the epiphyseal index, the index of overlapping of the head, the distance of the head from the floor of the acetabulum and the height of the peak of the greater trochanter above the centre of the head of the femur were assessed. In addition to assessment of these partial X-ray parameters the authors evaluated the spherical properties of the head by Mose's method and subjectively the X-ray picture, using a three grade scale (satisfactory, feasible, poor). In the majority of assessed parameters the authors found a statistically significant correlation with the retrospective classification of the original X-ray pictures classified according to Catterall. The clinical picture was satisfactory in the majority, the authors did not find painful restriction of movement, while almost half the patients reported occasional subjective complaints as regards the hip joint. On the X-ray changes in the overgrowth of the greater trochanter were more marked than changes of the spherical character of the head and the extent of decentering. The follow-up of the group will continue to obtain a longer time interval from the onset of the disease. Key words: Perthes disease, late results, Catterall's classification.
