In adults, a tibiofibular clear space (i.e., distance from the incisura fibularis to the medial fibula) of > or = 6 mm or a loss of tibiofibular overlap has been reported to correlate with injury to the distal tibiofibular syndesmosis. We reviewed anteroposterior (AP), lateral, and mortise ankle radiographs from 106 children (50 boys, 56 girls) aged 1-15 years in an attempt to assess whether these criteria are applicable to children. The incisura was detectable at a mean age of 8.2 years for girls and 11.2 years for boys. The range of tibiofibular clear space among the 48 children with a detectable incisura was 2-8 mm; seven (23%) of these 48 children had a clear space of > or = 6 mm in one or more views. The mean age at which the tibiofibular overlap began to appear on the AP view was 5 years for both genders, whereas on the mortise view, it was 10 years for girls and 16 years for boys. The criteria used to evaluate the integrity of the distal tibiofibular syndesmosis in adults do not apply to children in this normal study population.
据报道，在成人中，胫腓间隙（即从腓骨切迹到腓骨内侧的距离）≥6 mm或胫腓重叠缺失与下胫腓联合损伤相关。我们回顾了106名年龄在1至15岁的儿童（50名男孩，56名女孩）的踝关节前后位（AP）、侧位和斜位X线片，试图评估这些标准是否适用于儿童。女孩平均在8.2岁时可检测到腓骨切迹，男孩平均在11.2岁时可检测到。在48名可检测到腓骨切迹的儿童中，胫腓间隙范围为2至8 mm；这48名儿童中有7名（23%）在一个或多个视图中胫腓间隙≥6 mm。胫腓重叠在AP视图上开始出现的平均年龄，男女均为5岁，而在斜位视图上，女孩为10岁，男孩为16岁。在这个正常研究人群中，用于评估成人下胫腓联合完整性的标准不适用于儿童。
