There is some disagreement about whether idiopathic congenital talipes equinovarus (CTEV) increases the risk of neonatal developmental dysplasia of the hip (DDH). This study aimed to investigate the incidence of DDH in our infants with idiopathic CTEV.
We conducted an observational cohort study over a three-year period to assess the relationship between idiopathic CTEV and DDH. All neonates younger than six weeks with idiopathic CTEV who were treated in our medical centre were admitted to this study. Each subject underwent hip ultrasound examination using the Graf method at the age of six weeks. DDH was diagnosed when a hip was type IIa(-) or worse according to the Graf classification of sonographic hip type.
A total of 184 patients were diagnosed with idiopathic CTEV and underwent hip sonography. In total, seven hips of five individuals underwent treatment (four girls and one boy). The results indicated that 2.7% of babies (five of 184) with idiopathic CTEV had DDH. However, we did not find any statistically significant difference (p = 0.5776) in the Pirani scores between the DDH group and group with normal hips.
This study revealed that the idiopathic CTEV group had a greater incidence of DDH in comparison with the general population. It is recommended that hip sonography be undertaken particularly in patients with idiopathic CTEV.
关于特发性先天性马蹄内翻足（CTEV）是否会增加新生儿发育性髋关节发育不良（DDH）的风险，目前存在一些争议。本研究旨在调查我们患有特发性 CTEV 的婴儿中 DDH 的发病率。
我们进行了一项为期三年的观察性队列研究，以评估特发性 CTEV 与 DDH 之间的关系。在我们的医疗中心接受治疗的所有年龄小于 6 周的特发性 CTEV 新生儿均纳入本研究。每个受试者均在 6 周龄时采用 Graf 法进行髋关节超声检查。根据超声髋关节分型的 Graf 分类，当髋关节为 IIa（-）或更差时，诊断为 DDH。
共有 184 例患者被诊断为特发性 CTEV 并接受髋关节超声检查。共有 7 髋 5 例（4 名女孩和 1 名男孩）接受了治疗。结果表明，2.7%（5/184）患有特发性 CTEV 的婴儿患有 DDH。然而，我们并未发现 DDH 组与正常髋关节组之间的 Pirani 评分存在统计学差异（p=0.5776）。
本研究表明，特发性 CTEV 组的 DDH 发病率高于一般人群。建议对特发性 CTEV 患者特别进行髋关节超声检查。
