The authors studied 319 patients with adolescent idiopathic scoliosis treated at the same institution with either a Boston brace or a Charleston bending brace.
To determine if both orthoses are equally effective in stopping curve progression and preventing the need for surgical correction.
Early reports suggest that the Charleston brace may be comparable to the Boston brace in its effectiveness and that both braces positively influence the natural history of idiopathic scoliosis.
Skeletally immature (Risser 0, 1, or 2) patients with idiopathic scoliosis who were 10 years old or older at the time of brace prescription, had curves from 25 degrees to 45 degrees, and had no prior treatment were studied retrospectively. All measurements were collected by a single observer, and all patients were followed up to skeletal maturity.
The Boston brace is more effective than the Charleston brace, both in preventing curve progression and in avoiding the need for surgery. These findings were most notable for patients with curves of 36 degrees-45 degrees, in whom 83% of the those treated with a Charleston brace had curve progression of more than 5 degrees, compared with 43% of those treated with the Boston brace (p < 0.0001).
When given the choice between these two orthoses in the treatment of adolescent idiopathic scoliosis, the authors recommend use of the Boston brace. The Charleston brace should be considered only in the treatment of smaller single thoracolumbar or single lumbar curves.
作者对在同一机构接受波士顿支具或查尔斯顿弯曲支具治疗的319例青少年特发性脊柱侧凸患者进行了研究。
确定这两种矫形器在阻止曲线进展和避免手术矫正方面是否同样有效。
早期报告表明，查尔斯顿支具在有效性方面可能与波士顿支具相当，且两种支具均对特发性脊柱侧凸的自然病程产生积极影响。
对骨骼未成熟（Risser 0、1或2）、支具处方时年龄在10岁及以上、曲线度数为25度至45度且未接受过先前治疗的特发性脊柱侧凸患者进行回顾性研究。所有测量均由一名观察者收集，所有患者均随访至骨骼成熟。
在预防曲线进展和避免手术需求方面，波士顿支具比查尔斯顿支具更有效。这些发现对于曲线度数为36度至45度的患者最为显著，其中接受查尔斯顿支具治疗的患者中有83%曲线进展超过5度，而接受波士顿支具治疗的患者中这一比例为43%（p < 0.0001）。
在青少年特发性脊柱侧凸治疗中，当在这两种矫形器之间进行选择时，作者推荐使用波士顿支具。仅在治疗较小的单一胸腰段或单一腰段曲线时才应考虑使用查尔斯顿支具。
