[Electric excitability of the peroneal muscles in congenital equinovarus deformity]
Insights
Infants with congenital club foot show reduced peroneal muscle irritability before surgery. This irritability normalizes after surgical correction, suggesting muscles were stretched and normalized post-operation.

Abstract:
Irritability of the peroneal muscles by stimuli of the rectangular current in infants with congenital club foot was examined. Examinations were performed immediately before surgery in patients in general Ketamine anesthesia. The first group contained children with unilateral congenital club foot and the normal extremity was examined for comparison. In the group of children with bilateral club foot, one of the feet was examined twice about 4 months apart. A decrease of irritability of the peroneal muscles was found before operation. After operation this irritability reached the proper values. The authors think that the peroneal muscles in congenital club foot are stretched and that after correction of deformation their length and tension become normal.
