In a study in rabbits it was found that normal displacement of the site of insertion of a ligament or a tendon during growth in relation to the central part of the diaphysis of a tubular bone was inhibited when a metal wire was fixed in the metaphysis between the site of insertion and the epiphyseal plate. It was established from the change in site of metal wires implanted into the ligaments that the maximum increase in length of a growing ligament or tendon occurred in the position close to the site of insertion (Fig. 6). The results support the view propounded earlier in an autoradiographic study of the mechanism of displacement of the site of insertion, namely that two parellel processes are going on in the insertion area during growth. Firstly, the ligaments and tendons grow in length in proportion to the growth of the adjacent metaphysis of the bone, and secondly, newly formed tendon or ligament tissue is incorporated into the bone. Sixty rabbits were used for these experiments and twenty-nine unoperated animals served as controls.
