The results in seventy-nine adolescent patients (ninety-five curves) who had idiopathic scoliosis treated with the Wilmington brace are reported. The average follow-up was two years and six months (range, one to nine years). Before treatment, all of the patients had a curve that measured 20 to 39 degrees and a Risser sign of zero or 1. Although the magnitude of the curve was generally reduced by about 50 per cent with the initial application of the brace, a gradual loss of this initial improvement was observed both during active treatment and after the patient was weaned from the brace. Although twenty-seven (28 per cent) of the curves had progressed more than 5 degrees at follow-up, Lonstein and Carlson reported that the projected probability of progression of untreated 20 to 29-degree curves is 68 per cent. Thirty-six per cent of the thoracic curves, 16 per cent of the thoracolumbar and lumbar curves, and 28 per cent of the double major curves had progression of more than 5 degrees. However, only 11 per cent of the patients had a curve that progressed sufficiently to warrant fusion. Our findings indicate that the Wilmington brace favorably alters the natural history of 20 to 39-degree idiopathic curves.
报告了79例接受威尔明顿支具治疗的特发性脊柱侧弯青少年患者（95个弯曲）的结果。平均随访时间为两年零六个月（范围为1至9年）。治疗前，所有患者的弯曲度为20至39度，Risser征为0或1。尽管初次使用支具时弯曲度通常降低约50%，但在积极治疗期间以及患者停用支具后，均观察到最初改善情况逐渐丧失。尽管27个（28%）弯曲在随访时进展超过5度，但朗斯汀和卡尔森报告称，未经治疗的20至29度弯曲进展的预计概率为68%。36%的胸段弯曲、16%的胸腰段和腰段弯曲以及28%的双主弯进展超过5度。然而，只有11%的患者弯曲进展到足以需要进行融合手术。我们的研究结果表明，威尔明顿支具可有利地改变20至39度特发性弯曲的自然病程。
