Abstract:
The calcar femorale, first identified by Merkel in 1874, plays a pivotal role in the weight-bearing capacity of the proximal femur, and its structural integrity is crucial for the efficient distribution of mechanical loads. Originating at the vertical ridge where the pubofemoral ligament anchors, this bony prominence extends laterally behind the neutral axis from the medial to lateral aspects. Its presence is not merely an anatomical curiosity but significantly influences the biomechanics of the hip joint by providing additional strength and support against compressive forces encountered during activities such as walking or jumping. Despite its clear description in orthopedic texts, misconceptions persist about its exact function and importance. This article delves into the nuanced anatomy and biomechanical properties of the calcar femorale, offering a detailed literature-based examination that demonstrates its relevance in clinical practice. The review highlights how the robustness of the calcar femorale contributes to the prevention of femoral neck fractures as well as the stabilization of hip prostheses. Furthermore, the indispensable role of the calcar femorale in surgical outcomes is discussed, especially in the context of fracture repair and joint replacement, thus illustrating its enduring significance in contemporary medical applications.
摘要:
股骨calcar,默克尔于1874年首次确认,在股骨近端的承重能力中起着举足轻重的作用,其结构完整性对于有效分配机械载荷至关重要。起源于股韧带锚定的垂直脊,这种骨突出在中性轴后面从内侧到外侧横向延伸。它的存在不仅是解剖学上的好奇心,而且还通过提供额外的强度和支撑来抵抗诸如步行或跳跃之类的活动期间遇到的压缩力,从而显着影响髋关节的生物力学。尽管它在骨科文献中有明确的描述,关于它的确切功能和重要性的误解仍然存在。本文深入研究了股骨cal的细微差别的解剖学和生物力学特性,提供详细的基于文献的检查,证明其在临床实践中的相关性。该评论强调了股骨cal的坚固性如何有助于预防股骨颈骨折以及髋部假体的稳定。此外,讨论了股骨calcar在手术结果中不可或缺的作用,特别是在骨折修复和关节置换的背景下,从而说明其在当代医学应用中的持久意义。
