[Hormonal tendolysis in animal experiment]

After testing a new method of postoperative immobilisation the tendon of the m. flexor digit. longus of 49 adult rabbits was tenotomised and resewn. Comparing to a control-group a distinctly less accentuated reaction and scarring of the connected tissues as well as calcified reactionless necrosises can be found in the histology depending of the dosage of the postoperative cortison-treatment. The cellular alterations are described in details. For a definite judgement rupturing-tests will be necessary.
