Scheuermann's kyphosis. Results of surgical treatment by posterior spine arthrodesis in twenty-two patients.

Twenty-two patients with Scheuermann's kyphosis were treated with correction, Harrington instrumentation (in twenty-one), and posterior spine fusion. This procedure relieved pain and corrected deformity in all patients but loss of correction of 5 degrees or more occurred in sixteen of the twenty-two patients, including all those whose initial kyphosis was greater than 70 degrees. The incidence of complications was so high that this procedure should ordinarily be performed only for disabling pain or spinal cord compression.
