The paralytic theory, which received the support 294 of William J. Little, the father of orthopedic surgeryin England. Because of the similarity between thecongenital and the acquired forms it was assumed thatcongenital deformities were due to the same nerve-lesions that produced acquired clubfoot. Microscopicexamination, however, does not reveal the changes inthe brain and cord in cases of congenital clubfoot that. Fig. 236.—Bilateral congenital equinovarus.

The elec-trical reactions are not changed from the normal, and thevoluntary motion, the color and temperature of the skinand the muscles are quite different from what is foundin paralytic clubfoot. Further, paralytic clubfoot is the result of years of 295 malposition, no case becoming really deformed in soshort a period as nine months. In offering the aboveobjections to the paralytic theory we do not mean tosay that a case of paralytic clubfoot which has beenpresent from birth may not have antedated birth. We
