Many authors postpone triple arthrodesis in skeletally immature patients because they believe it may produce excessive shortening in a foot that is already short. Foot growth rates after triple arthrodesis were examined in this study between a group of skeletally immature patients (<11 years) and a group of more skeletally mature patients (>11 years). The skeletally immature group’s average age at surgery was 9.8 years, with a mean follow-up of 3.4 years, whereas the more skeletally mature group’s average age at surgery was 13.6 years, with a mean follow-up of 2.5 years. There were no statistically significant variations in length or height growth rates between the two groups after triple arthrodesis. In both groups, the rates of pseudoarthrosis and residual deformity were comparable to those found in prior investigations. This study refutes the notion that triple arthrodesis should only be performed on older children to rectify deformity, instability, or pain alleviation.
