[Calculating the progression of deformation scoliosis].

The authors have developed a mathematical model for the future prognosis of structural scoliosis which is based on the research on 97 patients with borne structural scoliosis. In order to make this mathematical model reliable, the authors propose a multicentrical research.

[Scoliosis in infancy].

1. The paper deals with 101 patients (52 male, 49 female) who have been treated in the first and second years of life because of resolving scoliosis and could be re-examined later at the age of 15 between 17 years. 2. The clinical and roentgenological findings of seven patients only had been normalized, where as in all other cases low lateral deviations of the spinal column (77 times), frequently at a modified type of curvature (44 times) or structural modifications (77 times, 17 spinal columns without lateral deviations), or not rarely, even both of them, had been found. 3. During development it came to a displacement of the vertex-vertebra on a average of 1-2 vertebrae to caudal. 4. No inspected resolving scoliosis had change over into a progressive scoliosis, a coherence consists not with idiopathic scoliosis of the prepuberty and puberty.

[Surgery of genuine Perthes' disease (author's transl)].

134 children between 3 and 13 years of age (average age 6.4 years) were treated at the Orthopaedic Clinic of the Karl-Marx-University at Leipzig between 1955 and 1977, for genuine Perthes' disease. The treatment consisted of bolting the capitular epiphysis (head) of the femur with a homologous bone chip. Anatomical healing was achieved in 50% of the cases. In almost 15% the results were good. The shape of the head was normal or almost normal, and there was merely a slight medium upward displacement of the trochanter without any functional significance. In 30% of the patients, the head was definitely no longer completely round, and there was a coxa vara symptomatic which, in three cases, was the reason for a surgical displacement of the trochanter. In 5--10% of the hip joints, the deformation had resulted in an incongruence of the head and acetabulum. The average treatment period was 17.1 months. The stage of the disease at the time of surgery did not exercise any influence on the duration and results of the treatment. Likewise, the position of the tip of the bone chip did not exercise any definitely appreciable influence.
