A recently published article by Song H et al. investigated the risk factors for anteromedial cortical support loss in pertrochanteric fractures treated with cephalomedullary nails. In this Correspondence, we would like to raise some concerns. Specifically, calcar fracture gap and anteromedial cortical support are different concepts in evaluating reduction quality. In addition, calcar fracture gap using immediate postoperative radiographic images has measurement bias. Lastly, explanatory variables selected for multivariable analysis are inappropriate. We would like to discuss and suggest solutions for these problems.
最近，Song H 等人发表了一篇文章，研究了使用股骨近端髓内钉治疗转子间骨折时前内侧皮质支持丢失的风险因素。在这封交流信件中，我们想提出一些关注。具体来说，骺环骨折间隙和前内侧皮质支持是评估复位质量的不同概念。此外，使用即刻术后影像学图像测量骺环骨折间隙存在测量偏倚。最后，多变量分析中选择的解释变量也不合适。我们想对此进行讨论并提出解决方案。
