The commonly used straight intramedullary nail has certain limitations and disadvantages. Following radiographic and metallurgical studies we have developed a curved heat-treated clover-leaf nail using a newly developed precipitation hardening stainless steel (COP). The nail is bent with a slot on the convex side and the radius of curvature is 115 cm which corresponds to the anatomical antero-lateral convexity of the human femur. The nail has been satisfactory in clinical use since 1971 and has provided not only more stable internal fixation but also allowed fixation of fractures beyond the middle third of the shaft.
常用的直形髓内钉有一定的局限性和缺点。经过影像学和金相学研究，我们采用新开发的沉淀硬化不锈钢（COP）研制出一种弯曲的热处理三叶草形髓内钉。该髓内钉在凸侧有一狭槽，其弯曲半径为115厘米，与人体股骨的解剖学前外侧凸度相对应。自1971年以来，该髓内钉在临床应用中效果令人满意，不仅提供了更稳定的内固定，还能固定骨干中下段以上的骨折。
