Straight-line graphs for the prediction of growth of the upper extremities.

Abstract

A simple graphic method was used for the prediction of growth and the determination of when a corrective procedure should be performed to equalize the lengths of the upper extremities. Straight-line graphs, similar to those described by Moseley for the lower extremities, were constructed for the radius, ulna, and humerus. The data for the current study were derived from a multidisciplinary, longitudinal study of growth in 244 healthy children (123 boys and 121 girls)--from infancy to skeletal maturity--and from previously constructed graphs depicting remaining growth. The use of this method can simplify the planning of an equalization procedure for an upper extremity.
