The too-long anterior process (TLAP) increases mechanical stress on the hindfoot and could lead to osteochondral lesions of the talus (OLT) by localized hyper-pressure. The purpose of this study is to investigate an association between TLAP and OLT in children.
This is a retrospective, multicenter, case-control study conducted between 2010 and 2020. The OLT group was compared to a control group (CoG). TLAP is characterized by a distance between the anteromedial process of the calcaneus and the navicular bone (CN) of< 5 mm.
Forty-three feets were included in the OLT group and 92 in the CoG. The OLT group had a lower CN distance on CT than the CoG, a median of 2.8 mm versus 3.75 mm (p = 0.002); 86% of patients (37 feet/43) in the OLT group had a CN distance of< 5 mm (OR=3.0 [1.1; 9.5], p = 0.023) compared to 67% in the CoG.
The OLT group had an increased risk of developing TLAP compared to the CoG.

过长的前距骨突（TLAP）会增加后足的机械应力，并可能通过局部高压导致距骨骨软骨损伤（OLT）。本研究旨在探讨 TLAP 与儿童 OLT 之间的关联。
这是一项回顾性、多中心、病例对照研究，于 2010 年至 2020 年期间进行。OLT 组与对照组（CoG）进行比较。TLAP 的特征是跟骨前内侧突与舟骨之间的距离<5mm。
OLT 组有 43 只脚，CoG 组有 92 只脚。OLT 组 CT 上的 CN 距离比 CoG 组低，中位数为 2.8mm 对 3.75mm（p=0.002）；OLT 组中 86%的患者（37 只脚/43 只）的 CN 距离<5mm（OR=3.0[1.1; 9.5]，p=0.023），而 CoG 组中为 67%。
与 CoG 相比，OLT 组发生 TLAP 的风险增加。
