Assessment of the accuracy of three techniques to predict leg length discrepancy.

Three techniques to predict leg length discrepancy were applied to a series of 50 patients with leg length inequality. The methods of Green and Anderson, the Moseley Chart, and a program written by the authors, designed to be run on a relatively inexpensive programmable calculator, were used.The data processed on the calculator produced slightly more accurate results than the Moseley Chart, though not statistically significant. The Green and Anderson technique resulted in the largest errors.
