女性青少年特发性脊柱侧凸患者停止支具治疗后的侧凸进展及其相关因素

目的 :分析发育成熟的女性青少年特发性脊柱侧凸(adolescent idiopathic scoliosis,AIS)患儿在停止支具治疗后长期随访中的侧凸进展情况,并探讨其相关因素。方法:回顾性分析于我院门诊就诊符合SRS(scoliosis research society)支具治疗标准的女性AIS患儿130例,初诊年龄11.8±1.4岁(10~14岁)。所有患儿均随访至支具治疗结束后至少2年,且至少具有佩戴支具后初次随访、停止支具治疗时、停止支具治疗后6个月、1年、2年及末次随访时的资料。在每次随访时的全脊柱正位X线片上测量主弯侧凸Cobb角,并评估侧凸进展超过5°的患儿及比例、侧凸进展度数和进展速率。末次随访时侧凸进展超过5°定义为侧凸进展,采用独立样本t检验比较侧凸进展组和非进展组患儿的初诊年龄、月经初潮年龄、初诊Cobb角、初始矫正率、停止支具治疗年龄。结果:与停止支具治疗时相比,停止支具治疗后6个月、1年、2年及末次随访时的侧凸进展超过5°的患儿分别为33例(25.4%)、42例(32.3%)、61例(46.9%)和63例(48.5%);侧凸进展度数分别为2.0°±4.4°、3.2°±5.0°、4.9°±5.5°和5.1°±6.9°;侧凸进展速率分别为0.33°±0.71°/月、0.20°±0.41°/月、0.14°±0.29°/月和0.01°±0.19°/月。停止支具治疗后侧凸非进展组和进展组患儿的初诊年龄、月经初潮年龄、初诊Cobb角、初始矫正率、停止支具治疗时年龄等无显著性差异(P0.05),而停止支具治疗时的Cobb角有统计学差异(P0.05)。结论:行支具治疗的AIS患儿停止支具治疗后仍有较高的侧凸进展风险,停止支具治疗后的6个月内为侧凸进展高风险和高速率期;停止支具治疗时的侧凸Cobb角越大发生侧凸进展的风险越高。     

支具治疗青少年特发性脊柱侧凸的临床随访

目的评价支具治疗青少年特发性脊柱侧凸的临床疗效,分析影响疗效的相关因素,并探讨支具治疗的适应证。方法对79例接受支具治疗的青少年特发性脊柱侧凸患者进行随访,记录患者的Cobb角,侧凸类型,女性患者初潮与否,坐高,站高,Risser征,顶椎旋转度等。结果随访12～60个月,平均23．9个月。末次随访时21例（26．6％）畸形明显进展,40例（50．6％）畸形维持或稍进展,18例（22．8％）畸形改善。初诊时原发弯Cobb角〉45°组侧凸进展率较Cobb角≤35°组高,侧凸改善率较Cobb角≤35°组低（P〈0．05）;顶椎旋转度Ⅲ°以上组侧凸进展率较0～Ⅱ°组高,侧凸改善率较0～Ⅱ°组低（P〈0．05）。侧凸类型、Risser征等参数不同的患者畸形进展和改善的比率均存在不同程度的差别,但差异不具有显著性（P〉0．05）。结论矫形支具能够有效控制或改善轻、中度特发性脊柱侧凸畸形。单独借助Risser征预测侧凸畸形变化趋势并不可靠。初始Cobb角〉45°,顶椎旋转度在Ⅲ°以上的患者,如果支具治疗的效果不佳,应考虑尽早手术矫形。     

青少年特发性脊柱侧凸的治疗

Potential genetic markers predicting the outcome of brace treatment in patients with adolescent idiopathic scoliosis

Purpose  

To investigate whether the predisposition genes previously reported to be associated with the occurrence or curve severity of adolescent idiopathic scoliosis (AIS) play a role in the effectiveness of brace treatment.     

Evolution of the curve patterns during brace treatment for adolescent idiopathic scoliosis

Summary of background data

The curve pattern of idiopathic scoliosis is important for making decisions concerning bracing. However, whether the curve pattern changes during brace treatment have not been fully documented. The aim of this study was to investigate the changes of curve pattern during brace treatment in skeletally immature patients with adolescent idiopathic scoliosis (AIS).

Methods

From January 2002 to January 2011, AIS patients treated with a Boston or Milwaukee brace were recruited after meeting the following inclusion criteria: older than 10 years of age at initiation of bracing; having a Cobb angle of 25°–40°; with a Risser sign 0–2; being regularly followed until the weaning of brace or the necessity of surgical treatment; and without history of previous treatment. A total of 130 female and 11 male AIS patients were included. The mean age was 12.9 years at initiation of bracing, and the female patients were, on average, 2.7 months past menarche. The mean follow-up period was 2.6 years (range 1.0–5.5 years). The definitions of changes in curve patterns were divided into four categories as follows: (1) shift of the apex of the main curve; (2) change in the curve span of more than two vertebrae; (3) change in the main curve type with regard to the apex location; and (4) change of curve direction. The patients were divided into two groups. Group A was comprised of patients who had experienced one or more categories of curve pattern changes, and Group B was comprised of those who had not.

Results

Of these 39 patients, 14 had apex shifting, 2 underwent curve span changes, 22 experienced changes in the main curve type, and one female had both changes in the apex and curve span. At the initiation of bracing, patients in Group A demonstrated significantly lower menarchal status (P = 0.018) and lower Risser grade (P = 0.025) than those in Group B. The difference in the percentage of patients who underwent Boston bracing between the two groups was statistically significant (41.5 % for Group A vs. 24.0 % for Group B, P = 0.023).

Conclusion

Changes in curve pattern can occur during brace treatment. Patients with less skeletal maturity and those treated with a Boston brace are more susceptible to this phenomenon.

目的:比较马方和类马方综合征脊柱侧凸(Marfan syndrome and Marfanoid scoliosis,MMS)患者与青少年特发性脊柱侧凸(adolescent idiopathic scoliosis,AIS)患者肺功能的差异及影响因素。方法:1999年9月~2013年4月我院收治的以胸弯(冠状面)为主的马方及类马方综合征脊柱侧凸患者共85例,其中年龄为11~19岁且临床资料完整的患者共40例(MMS组),男14例,女26例;收集患者术前肺功能指标,包括第1秒最大呼气容积(FEV1)、用力肺活量(FVC)、最大用力呼气峰流量(PEF),数值采用实测值占预计值的百分比,分析肺功能指标与年龄、冠状面Cobb角、胸后凸Cobb角、胸弯柔韧度之间的关系。并与同期住院行脊柱侧凸矫形内固定术的相匹配的80例AIS患者(AIS组)的术前肺功能参数进行比较。采用曼-惠特尼U检验比较两组间的差异,并用Pearson相关性分析对两组患者肺功能指标与患者年龄及相关脊柱侧凸指标进行相关性分析。结果:MMS组患者中肺功能处于中、重度损害的比例(11/40)显著高于AIS组(5/80)(P0.05)。MMS组患者FEV1、FVC均明显小于AIS组患者(P0.05);PEF两组间差异无统计学意义。MMS组患者FEV1、FVC与冠状面Cobb角呈显著性负相关(r=-0.444、-0.524,P0.05);FEV1、FVC、PEF与年龄之间呈正显著性相关(r=0.363,0.326,0.348,P0.05);FVC与胸弯冠状面柔韧度之间呈显著性正相关(r=0.321,P0.05);FEV1、FVC与胸椎后凸角均无显著相关性。AIS组患者FEV1、FVC、PEF等指标与冠状面Cobb角呈显著性负相关(r=-0.338、-0.293、-0.253,P0.05);FEV1、PEF与年龄之间呈显著性正相关(r=0.286、0.341,P0.05);FEV1与胸后凸Cobb角之间呈显著性正相关(r=0.238,P0.05)。两组患者肺功能指标与相关指标间的相关性存在差异。结论:MMS患者肺功能损害较AIS患者严重,其肺功能主要受胸弯冠状面Cobb角、年龄共同影响。     

Results of brace treatment of adolescent idiopathic scoliosis in boys compared with girls: a retrospective study of 102 patients treated with the Boston brace

The aim of the study was to compare the results of brace treatment of adolescent idiopathic scoliosis (AIS) in male patients with matched female patients and to assess the effectiveness of bracing of boys in AIS and to discuss the results with published data. Between 1987 and 1995, 51 consecutive male patients with AIS were treated with the Boston brace. The patients were advised to wear the brace 23 h/day. The medical records of all patients were reviewed. Cobb angles and Risser signs were measured before bracing, in brace, at brace discontinuation and at final follow-up. Everyone of 51 male patients was compared with a female patient who was treated by the same method and matched by Risser sign, curve pattern, curve magnitude and duration of treatment and follow-up time. Compliance with brace was noted at every visit. Fourteen boys had worn the brace only during nighttime or occasionally and were considered non-compliant. Only compliant patients with treatment period > 1 year and follow-up > 1 year after treatment were accepted for the analyses of effectiveness of brace treatment and its prognostic factors. Thirty-three boys met these inclusion criteria. Bracing was considered to have a failure if > 5° progression occurred or if surgery was performed. At the final follow-up study progression > 5° was found in 16/51 (31.4%) of male patients. Corresponding figures of female patients were 11/51 (21.6%), respectively. In compliant boys progression > 5° occurred in 6/33 boys compared with 9/33 girls. The association between risk of progression and correction% in brace was statistically significant. The overall results of brace treatment of idiopathic scoliosis in male patients were inferior compared with matched females. One reason for inferior overall results in boys was poor compliance with brace wear. However, brace treatment in AIS may be recommended with the same principles in both genders.     

Health-related quality of life in patients with adolescent idiopathic scoliosis after treatment: short-term effects after brace or surgical treatment

For treatment of teenagers with progressive adolescent idiopathic scoliosis in an early stage, two options are generally considered: treatment with a brace or observation followed by surgery if necessary. Many doctors and patients prefer conservative treatment (i.e. brace treatment) to surgical treatment, because surgery of the spine is generally considered a drastic intervention. Because potential differences in health-related quality of life (HRQoL) after treatment between braced and surgically treated patients are not well explored, this study aimed to determine whether short-term differences exist in HRQoL between adolescents treated with a brace or treated surgically. A cross-sectional analysis of HRQoL was made of 109 patients with adolescent idiopathic scoliosis who, after completing treatment, filled out the Dutch SRS-22 Patient Questionnaire. All patients had been treated either with a brace or surgery, or with a brace followed by surgery. Patients treated surgically had significantly higher mean scores in the satisfaction with management domain than those treated with a brace. No other consistent differences in HRQoL were found between patients treated with a brace and patients treated surgically. Gender, curve type and curve size had no relevant effect on HRQoL. We conclude that short-term differences in HRQoL after treatment in adolescent patients with idiopathic scoliosis are negligible and cannot support preference of one treatment above the other.
