“…With long term brace treatment there is a reduction in lung volumes, probably due to external compression of the chest wall 25. However, brace treatment for 2 years did not reduce lung volumes 26.…”

Background-Pulmonary function in patients with adolescent idiopathic scoliosis many years after posterior spinal surgery or brace treatment has not been documented. Methods-A consecutive group of patients treated by posterior fusion or a brace at least 20 years previously was investigated. 90% attended a clinical follow up. Lung volumes were determined before treatment in 251 patients, 1.4 years after surgery in 141 patients, and 25 years after surgery or start of brace treatment in 110 patients. Vital capacity (VC) was calculated as percentage predicted according to height and age and the results were corrected for loss of height due to scoliosis. Scoliosis angles were measured and smoking habits were recorded. An age and sex matched control group was also examined with the same questionnaire and pulmonary function tests. Results-VC increased from 67% predicted immediately before surgery to 73% (p<0.001) after surgery and to 84% (p<0.001) at the present follow up, mean change 10.8% (95% CI 9.5 to 12.1). In the brace treated patients VC increased from 77% predicted before treatment to 89% (p<0.001) 25 years after start of treatment, mean change 12.3% (95% CI 10.5 to 14.1). The mean Cobb angle at the present follow up study was 40°in both surgically and brace treated patients. The present results of lung volumes did not correlate with pretreatment or post-treatment Cobb angles or smoking habits.

“…As expected, preoperative brace treatment duration was negatively, but the sagittal Cobb's angle of the thoracic curve was positively associated with both the FVC% and FEV1%. In consideration of the harmful effect of bracing on pulmonary function, [ 12–15 ] it is not difficult to understand the longer time of the brace wearing, more aggravated pulmonary function was present. Therefore, the duration of brace wearing should be timely adjusted according to the pulmonary function test.…”

“…In accordance with the improvement in curve progression, the study of Pehrsson et al [12] indicated bracing also could significantly improve pulmonary function such as vital capacity (3.8 ± 0.7 L vs 3.4 ± 0.6 L, P < 0.05) and forced expiratory volume in 1 s (FEV1: 3.1 ± 0.5 L vs 2.9 ± 0.5 L, P < 0.05). However, some studies reveal that wearing a brace may aggravate pulmonary function, [ 12–15 ] which may be attributed to increased stiffness of the thoracic cage and restricted growth in the lung tissues [16] . These studies indicate a controversial conclusion about the influence of bracing on pulmonary function and further study is needed.…”

“…These studies indicate a controversial conclusion about the influence of bracing on pulmonary function and further study is needed. Importantly, most of the literatures focused on comparing the results between before and after brace, [ 12 15 ] only the study of Yu et al [14] aimed to observe the differences between preoperative brace treatment and without preoperative brace treatment. Nevertheless, only female AIS patients were included in the study of Yu et al [14] …”

Pulmonary function changes and its influencing factors after preoperative brace treatment in patients with adolescent idiopathic scoliosis

et al. 2016

Background:The aim of the study was to retrospectively investigate the changes in pulmonary function and its influencing factors in patients with adolescent idiopathic scoliosis (AIS) undergoing preoperative brace treatment or not.Methods:Total 237 AIS patients (43 boys, 194 girls) who underwent operations and had a complete record of pulmonary function tests were enrolled and were divided into preoperative brace treatment group (brace treatment group, n = 60) and without preoperative brace treatment group (control group, n = 177). The pulmonary function parameters were compared between the 2 groups. Multiple linear regression analysis was performed to explore whether the variables, including age at operation, height, coronal Cobb's angle of main curve, number of involved vertebrae, sagittal Cobb's angle of thoracic curve, brace treatment time per day and brace treatment duration, influenced pulmonary function in the brace treatment group.Results:No significant differences were observed in both predicted and actually measured value of forced vital capacity (FVC) and predicted value of forced expiratory volume in 1 s (FEV1) between 2 groups (P > 0.05), but actually measured FEV1, the percentage of actually measured and predicted value of FVC (FVC%) and FEV1 (FEV1%) were significantly lower in the brace treatment group than those in the control group (P < 0.05). Importantly, the above changes in actually measured FEV1 and FEV1% were obvious in AIS patients presented with a main thoracic curve (P < 0.05), but not in patients with a primary thoracolumbar/lumbar curve. Multiple linear regression analysis indicated that only the sagittal Cobb's angle of the thoracic curve was positively, but preoperative brace treatment duration was negatively associated with both the FVC% and FEV1% (P < 0.05).Conclusion:Preoperative brace treatment may deteriorate pulmonary function in AIS patients with thoracic curve. The small sagittal Cobb angle and longer brace treatment duration may be risk factors for reduced pulmonary function.

In addition, Boston brace has been shown to reduce lung volume and pulmonary compliance compared to pre-brace levels 71. Brace wear has been found to have no effect on bone mineral densitometry 72…”

Adolescent idiopathic scoliosis is the most common spinal deformity encountered by General Orthopaedic Surgeons. Etiology remains unclear and current research focuses on genetic factors that may influence scoliosis development and risk of progression. Delayed diagnosis can result in severe deformities which affect the coronal and sagittal planes, as well as the rib cage, waistline symmetry, and shoulder balance. Patient's dissatisfaction in terms of physical appearance and mechanical back pain, as well as the risk for curve deterioration are usually the reasons for treatment. Conservative management involves mainly bracing with the aim to stop or slow down scoliosis progression during growth and if possible prevent the need for surgical treatment. This is mainly indicated in young compliant patients with a large amount of remaining growth and progressive curvatures. Scoliosis correction is indicated for severe or progressive curves which produce significant cosmetic deformity, muscular pain, and patient discontent. Posterior spinal arthrodesis with Harrington instrumentation and bone grafting was the first attempt to correct the coronal deformity and replace in situ fusion. This was associated with high pseudarthrosis rates, need for postoperative immobilization, and flattening of sagittal spinal contour. Segmental correction techniques were introduced along with the Luque rods, Harri-Luque, and Wisconsin systems. Correction in both coronal and sagittal planes was not satisfactory and high rates of nonunion persisted until Cotrel and Dubousset introduced the concept of global spinal derotation. Development of pedicle screws provided a powerful tool to correct three-dimensional vertebral deformity and opened a new era in the treatment of scoliosis.
