When it comes to injuries of the collateral ligament in the metacarpal-phalangeal joint of the thumb, the best results have proved to be obtainable from primary surgery. Secondary ligament surgery according to Strandel, in its modification by Bäuerle and Reill, has its clear-cut indication and ensures restoration of thumb functionality. Arthrodesis is an alternative that should be chosen with generosity.

The antibodies of 50 old people of the age over 70 years were determined against ds-DNA and denaturized ds-DNA by the immune-fluorescence method, and it can be stated that denaturized ds-DNA antibodies are traceable in 16% of these sera. Such antibodies could not be found in control tests of seras of young people. However, the old people did not show may clinical symptom typical of the disease caused by these antibodies. In particular, there were no indications of an auto-immune disease, for that reason, these antibodies are to be considered as optional pathological ones.
