A constant rotational speed can be restored by fitting a second joint in a way such that when the first joint increases its speed the second joint decreases its speed.
要实现等速，必须以某种方式安装第二个万向节，这样第一个万向节使转速增大，第二个万向节就使转速减少。
Conclusions: By complete subtalar release, rotational reduction of the talocalcaneal joint can be accomplished in total correction of deformity.
结论：距下完全松解术，跟骨与距骨之间得到充分旋转复位，而使畸形得到较好的纠正。
