    Abstract:
    Objective: To summarize the characteristics of multisystem deformities in patients with Klippel-Feil syndrome (KFS) combined with congenital scoliosis (CS). Methods: Within the framework of the "Deciphering Disorders Involving Scoliosis and Comorbidities (DISCO)" research collaboration, a retrospective analysis was conducted on patients diagnosed with KFS and CS at Peking Union Medical College Hospital between April 2005 and August 2022. Patient data, including imaging examinations and medical records, were collected to summarize the spinal and associated deformities. Results: A total of 82 KFS patients with concurrent CS were included, comprising 42 males and 40 females. The average age was (12.8±8.9) years. Among the KFS patients, there were 31 cases of Type Ⅰ, 12 cases of Type Ⅱ, and 39 cases of Type Ⅲ. The most common location for the major curve of scoliosis was the mid-thoracic segment (42 cases, 51.2%). Hemivertebrae deformities were most frequently observed in the upper thoracic segment (31 cases, 60.8%). There were no statistically significant differences in age, gender, major curve Cobb angle, or region of hemivertebrae occurrence among the different types of KFS (all P>0.05). Apart from spinal vertebral deformities, intraspinal deformities had the highest comorbidity rate (33 cases, 40.2%). The subjects were divided into two groups based on the presence or absence of intraspinal deformity (absence as group G0, presence as group G1), there was a statistically significant difference in the main Cobb angle [M(Q1, Q3)] between the two groups, which was 45.0° (27.5°, 62.0°) and 60.0° (37.5°, 83.5°), respectively (P=0.044). Additionally, a portion of the patients had concurrent cardiovascular system abnormalities (13 cases, 15.9%), craniofacial-ocular-auricular abnormalities (8 cases, 9.8%), genitourinary system abnormalities (7 cases, 8.5%), and gastrointestinal abnormalities (2 cases, 2.4%). Conclusions: Patients with KFS combined with CS commonly present with a major curve of spinal deformity in the mid-thoracic segment and often have comorbidities involving multiple systems. When combined with intraspinal anomalies, the major curve exhibits a greater degree of curvature. 目的： 总结Klippel-Feil综合征（KFS）合并先天性脊柱侧凸（CS）患者的多系统畸形特征。 方法： 在“系统解析脊柱畸形及相关合并症”（DISCO）研究协作组框架下，回顾性分析2005年4月至2022年8月于北京协和医院就诊并被诊断为KFS伴CS患者的临床资料。收集患者的影像学检查、病历资料等，总结脊柱及其他系统伴发畸形的情况。 结果： 共纳入82例合并CS的KFS患者，其中男42例，女40例，年龄（12.8±8.9）岁。Ⅰ型KFS患者31例，Ⅱ型12例，Ⅲ型39例。脊柱侧凸的主弯最常见于中胸段（42例，51.2%）。半椎体畸形最多发于上胸段（31例，60.8%）。KFS各分型间，年龄、性别、主弯Cobb角、半椎体发生区域差异均无统计学意义（均P>0.05）。除脊柱椎体畸形外，椎管内畸形伴发率最高（33例，40.2%）。按是否存在椎管内畸形分为两组（不存在为G0组，存在为G1组）进行比较，两组间主弯Cobb角［M（Q1，Q3）］差异有统计学意义［分别为45.0°（27.5°，62.0°）和60.0°（37.5°，83.5°），P=0.044］。另有部分患者合并心血管系统（13例，15.9%）、面-眼-耳部（8例，9.8%）、泌尿生殖系统（7例，8.5%）及胃肠道（2例，2.4%）畸形。 结论： KFS合并CS的患者畸形主弯最常见于中胸段，常合并多系统畸形。当合并椎管内畸形时，主弯度数更大。.
