The Scottish Rite abduction orthosis for the treatment of Legg-Perthes disease. A radiographic analysis.

We evaluated a consecutive series of thirty-four patients who had had Legg-Perthes disease to determine the results of treatment with the Scottish Rite weight-bearing abduction orthosis. All patients had been older than six years at the time of the onset of the symptoms, had been in the fragmentation phase of the disease when they were first seen, and had had Catterall group-III or IV involvement. Although comparison of this series with those reported previously is difficult due to the variability of the presentation of data in the literature, this orthosis does not appear to offer an advantage compared with other methods of management, or with no treatment, for patients such as those whom we studied.
