青少年特发性脊柱侧凸(adolescent idiopathic scoliosis,AIS)是指年龄在1018岁,冠状面上Cobb角>10°伴有椎体的旋转而无其他器质性病变的一种常见病。该疾病能够导致身体外观畸形、疼痛,甚至心肺功能受损,严重影响了患者的身心健康及生活质量。在治疗上,对于轻中度的AIS患者常用定期观察、支具等保守治疗方法,能够有效的延缓侧凸的进展;对于保守治疗无效,达到手术阈值的AIS患者,则建议手术治疗,目前较为常用的手术方法是以椎弓根螺钉内固定系统为代表的后路椎体融合术,往往能够达到较好的临床疗效。近年来,由于物理治疗性脊柱侧凸特异性运动(PSSE)疗法安全有效,越来越受欢迎。目前对于AIS患者治疗的具体适应证正逐渐完善,治疗理念与技术在不断更新,临床疗效也不断得到改善。本文将从保守治疗和手术治疗两方面展开,主要阐述常用的治疗方法在临床上的进展和应用以及所面临的问题,为临床治疗的选择提供参考。 相似文献

青少年特发性脊柱侧凸的选择性融合 总被引:7,自引:0,他引:7
手术治疗青少年特发性脊柱侧凸(adolescentidiopathicscoliosis,AIS)的目的是矫正脊柱畸形、稳定侧凸、重建或保持脊柱的平衡。临床上通常根据冠状面的Cobb角、骨骼发育情况、矢状面变化、椎体旋转程度以及侧凸的自然史来判断是否需手术治疗。一般认为,对处于生长期、Cobb角>50°、非手术治疗无效、疼痛、胸椎前凸及伴有明显外观畸形的患儿应选择手术治疗。自1914年首例采用脊椎融合术治疗侧凸以来,确定AIS手术合适的融合节段一直是众多学者争论的焦点;AIS手术是否成功有赖于对融合节段的正确选择,选择不当易引起脊柱侧… 相似文献

Height of girls with adolescent idiopathic scoliosis 总被引:13,自引:0,他引:13
Mauno Ylikoski 《European spine journal》2003,12(3):288-291
In a Finnish population, the standing height of 1500 consecutive female patients aged 9-24 years (mean 13.9 years) with untreated idiopathic scoliosis of at least 10 degrees in their lateral curves was compared with the standing height of average girls. The mean magnitude of the major curves was 29.4 degrees (range 10 degrees-80 degrees), and that of the minor curves 20.3 degrees (range 0 degrees-66 degrees). A formula for the height loss caused by the lateral curves, and that caused by thoracic kyphosis, was derived. The corrected height of the girls with idiopathic scoliosis was highly significantly (P<0.001) greater than the height of average girls at the age of 11-15, and this high level of significance was present at the age of 11-13, even without correcting for the height loss caused by scoliosis. After maturation, the girls with idiopathic scoliosis were not significantly taller than average girls. On average, the magnitude of thoracic kyphosis did not affect the height of patients with scoliosis as compared with the height of normal girls of the same age. 相似文献

Background contextAbnormal somatosensory evoked potentials (SEPs) have been documented in patients with adolescent idiopathic scoliosis (AIS) with different cure severity. However, few studies investigated whether abnormal SEPs were the cause or effect of idiopathic scoliosis.PurposeThe purpose of this study was to investigate the significance of abnormal SEPs in patients with AIS, and to explore its effect on the etiopathogenesis of AIS.Study design/SettingThis study evaluated SEPs in patients with AIS and congenital scoliosis (CS) with similar curve pattern and severity both in coronal and sagittal planes.Patient sampleFemale patients with AIS and CS in our spine surgery center from 2000 to 2009 were recruited for this study.Outcome measuresRate of abnormal SEPs.MethodsPosterior tibial nerve SEPs (PTN-SEPs) were performed on female patients with AIS and CS. The inclusion criteria were patients with AIS with a Lenke type 1 curve and patients with CS with right thoracic curve (apex between T5 and T12) and normal sagittal profile (kyphosis less than 50° measured from T2 to T12). All patients were evaluated with total spine magnetic resonance imaging, and those with neural axis abnormalities were excluded. The patients with neurological deficits on detailed physical examination were also excluded. Absence of SEPs waveforms or prolongation of peak latency or asymmetrical peak latency were defined as pathological change. The incidence of pathological SEPs and clinical characteristics were compared between patients with AIS and patients with CS.ResultsForty-six patients with AIS and 33 patients with CS were included in this study. There was no significant difference in coronal and sagittal Cobb angle between the two groups. The rate of abnormal SEPs was 32.6% (15/46) and 12.1% (4/33) in AIS and CS groups, respectively, and the difference was statistically significant (p<.05).ConclusionSomatosensory pathway dysfunction could be found in both AIS and CS without neural axis abnormalities, and the patients with AIS tended to have higher rates of somatosensory disorders than patients with CS with similar scoliosis curve, which indicates that both scoliosis curve and primary etiopathogenic factor contribute to the sensory deficit in patients with AIS. 相似文献

Summary The spinal growth in scoliotic segments (T4-L4) of 110 girls with untreated idiopathic scoliosis was measured from two successive radiographs taken at a mean interval of 1.1 years. At the first visit the mean age of the patients was 14 years (range 11–16 years), the mean magnitude of the major curves 24° (range 9°–38°) and that of the minor curves 14° (range 2°–38°). Spinal growth was most rapid at the age of 11–12 years. The progression of the curves (major plus minor) correlated with the spinal growth (r=0.384). The greater the initial curves were, the stronger the correlation was between the spinal growth and the progression of the curves (r=0.046–0.639), and the correlation was more significant in thoracic scoliosis (r=0.560) than in thoracolumbar and lumbar scoliosis (r=0.152). 相似文献

There have been great advances in the conservative and surgical treatment for adolescent idiopathic scoliosis in the last few decades. The challenge for the physician is the decision for the optimal time to institute therapy for the individual child. This makes an understanding of the natural history and risk factors for curve progression of significant importance. Reported rates of curve progression vary from 1.6% for skeletally mature children with a small curve magnitude to 68% for skeletally immature children with larger curve magnitudes. Although the patient''s age at presentation, the Risser sign, the patient''s menarchal status and the magnitude of the curve have been described as risk factors for curve progression, there is evidence that the absolute curve magnitude at presentation may be most predictive of progression in the long term. A curve magnitude of 25° at presentation may be predictive of a greater risk of curve progression. Advances in research may unlock novel predictive factors, which are based on the underlying pathogenesis of this disorder. 相似文献

Adolescent idiopathic scoliosis is a common disease with an overall prevalence of 0.47–5.2 % in the current literature. The female to male ratio ranges from 1.5:1 to 3:1 and increases substantially with increasing age. In particular, the prevalence of curves with higher Cobb angles is substantially higher in girls than in boys: The female to male ratio rises from 1.4:1 in curves from 10° to 20° up to 7.2:1 in curves >40°. Curve pattern and prevalence of scoliosis is not only influenced by gender, but also by genetic factors and age of onset. These data obtained from school screening programs have to be interpreted with caution, since methods and cohorts of the different studies are not comparable as age groups of the cohorts and diagnostic criteria differ substantially. We do need data from studies with clear standards of diagnostic criteria and study protocols that are comparable to each other. 相似文献
