It would have carried us far beyond the intent of this modest paper to outline in detail the clinical symptoms of the affections of single joints, their earliest states, their clinical course and the influence of injuries or even the therapy which is so successful in the treatment of static diseases. Whoever is interested in these matters may read my extensive book on static joint diseases (F. Enke Stuttgart, 1911). In this paper I simply wished to point to a few too little known pictures of diseases which have as their cause anomalies of the statics of the bones and joints. Furthermore it was my idea to ask my American orthopedic colleagues to join us in the investigation of a field which is worthy to be separated, because of successful therapy, from the general collection of chronic arthritis and which, if thoroughly worked out by orthopedists may become one of the main fields of orthopedic surgery, as our material proves (about 4000 cases of static arthritis in somewhat more than nine years). In practice the early recognition of the disturbance of the statics of a joint is extremely important, because of the fact that at times extremely severe troubles may be caused by such disturbances. Negligence of the disease, causing it to be confounded with rheumatism, gout and other chronic affections of the joints, may lead to the most grave therapeutic errors and may be the cause of patients going for years and decades from one physician to another, from one bath to another, seeking for a cure while an expert will at once succeed if, guided by the significance of incongruence of the articular surfaces which has been briefly outlined in this paper, he is led to make the right diagnosis and to apply the correct therapy.
