Manual force con-tinuously applied may be supposed to stretch the resistant parts,and although much less power is exerted it is really more effec-tive than the sudden and momentary force of the wrench orosteoclast, because it may be continued until the deformity hasbeen overcorrected, while complete correction by mean& of in-struments may necessitate several operations.

The wrenching may or may not be preceded by ten-otomy, a point to be decided by the resistance of the parts. Asa rule, division of the tendo Achillis alone is necessary.
