文摘目的探讨扁平足病人中特发性脊柱侧凸(idiopathic scoliosis,IS)的发病情况及影像学特征,分析扁平足病人合并IS的危险因素。方法回顾性分析2021年10月至2023年3月于武汉儿童医院就诊的608例扁平足病人的一般情况和影像学资料,统计扁平足病人中IS的发病率,采用秩和检验比较IS病人与非IS病人、IS中Cobb角>20°病人与Cobb角≤20°病人的一般情况及足影像学参数。采用单因素分析IS病人与非IS病人、IS中Cobb角>20°病人与Cobb角≤20°病人左足外翻角(hallux valgus angle,HVA)、右足HVA、左足(侧位)距骨第1跖骨角(Meary’s angle,MA)、右足MA、HVA差值、MA差值等指标,将P<0.20的指标纳入多因素Logistic回归分析,评估扁平足病人发生IS的危险因素,扁平足合并IS病人Cobb角>20°的危险因素。结果608例扁平足病人中,发生IS的有67例(67/608,11.01%)。扁平足合并IS病人与非IS病人比较,存在双侧外翻角不对称和双侧足弓不对称,差异均有统计学意义(P<0.05)。大于10岁病人(OR=2.866,95%CI:1.683~4.881,P<0.001),女性病人(OR=1.892,95%CI:1.121~3.193,P=0.017),双侧足弓不对称的扁平足病人(OR=1.194,95%CI:1.023~1.393,P=0.025),有更高的IS患病风险。IS病人Cobb角>20°病人左足足弓水平低于Cobb角≤20°病人(P=0.019)。结论IS在扁平足病人中的发病率可能较正常人群发病率高。扁平足合并IS病人存在双侧足形态不对称,包括双侧外翻角不对称及双侧足弓不对称,且双侧足弓不对称是扁平足合并IS的危险因素。
