1. Selected cases of inequality of length of limbs during the growing period may be treated by epiphyseodiaphyseal fusion, arresting growth in the longer limb, and thereby approximating or equalizing limb lengths at the end of the growth period.

2. Angular deformities of the wrist or ankle, the result of disproportion in length of the two bones of the forearm or leg, may be improved by either unilateral or complete arrest of growth in the longer bone at the appropriate age.
