Limited Torsion Above the Epididymis.—As we have seen, this is the operation by which the division of the spermatic cord is effected by torsion made upon a given point in its length, and limited by the use of special instruments.

We have already called attention to the difficulty of the operation of free torsion, which requires a great deal of strength, and which, besides, may be accompanied by a serious inflammatory condition of the parts, through rough manipulations of the cord. It is for this reason that this mode of procedure must have been reserved for small animals, as, if performed upon the larger kinds, it can only be by men whose muscular force is sufficient to enable them to overcome and bring into subjection the struggling subjects of their operations.
