Effects of splitting the iliac apophysis on subsequent growth of the ilium: a rabbit study

We wished to determine if splitting the iliac apophysis in a skeletally immature animal would affect subsequent growth of the ilium. Thirty-two rabbits were divided into six groups. One group was the sham group; the other five groups received different types of surgical splitting and repair of the iliac apophysis. The results suggested that any splitting of the iliac apophysis in an immature animal significantly affects subsequent growth of the ilium. The type of repair apparently does not affect the amount of growth retardation. Using electrocautery to split the iliac apophysis has a significantly greater effect on growth of the ilium.
