TO THE EDITOR:
We read "Use of the Milwaukee Brace for Progressive Idiopathic Scoliosis" (78-A: 557567, April 1996), by Noonan et al., with considerable interest. We were particularly struck by the difference between their analysis of results and ours5.
As the details in both articles are reviewed, the reason for the difference becomes clear. First, Noonan et al. reviewed the results for 102 patients, although those for only eighty-eight were analyzed statistically since they, unlike us, eliminated patients who had curves of more than 45 degrees. A statistically valid comparison of this small group of eighty-eight patients with the 1020 patients in our study is difficult, especially when the results have to be subdivided according to age, curve, magnitude, and compliance.
Second, the duration of treatment with the brace in their study (one year and eight months) was much shorter than that in ours (three years and eight months).
