[Perthes' disease: a roentgenological clinic study (author's transl)]. / M. Perthes. (Röntgenologisch-klinische Studie).

Perthes' disease (a condition also known as Legg-Calvé-Perthes disease), or osteochondrosis of the head of the femur, has been repeatedly subdivided into several stages and subjected to classifications which are hardly satisfactory in practice. Catterall has presented a new group classification on the basis of untreated cases of Perthes' disease, which has been combined in the present paper with Somerville's subdivision into different stages. This subdivision into groups and stages was examined for feasibility and practical usefulness via 51 cases of Perthes' disease. It was found that both systems of grouping and classification sometimes required repeated correction in the course of the disease. Hence, this subdivision remains unsatisfactory, especially when therapeutic consequences are expected to be drawn. Cases for Perthes' disease treated by the authors are described and compared with the data given in medical literature.

Features resisting primary treatment of congenital club foot.

The aims of this study were: (1) to see whether the number of relapses of hindfoot deformity in congenital club foot in the first year of life could be reduced by operative treatment, and (2) to try by surgery to pinpoint features of congenital club feet that make them resistant to treatment. As compared to treatment of 95 feet with manipulation and plaster cast only or with heel cord tenotomy added, early tenotomy of both the heel cord and the tibialis posterior tendon in 23 feet markedly reduced the number of relapses of hindfoot deformity, and the need for additional treatment. The results indicate that the achilles and the tibialis posterior tendons, and their corresponding muscles, are the main dynamic features that need to be dealt with when treating the hindfoot deformity in congenital club foot.
