The biomechanical properties of commercially available locked nail systems designed for use in comminuted femoral shaft fractures were compared and evaluated. Ender nails as well as three forms of interlocking nails, Brooker-Wills (B-W), Klenm-Schellman (K-S), and Grosse-Kempf (G-K), were implanted in cadaver femora. The femora were tested in torsion, bending, and axial loading to failure. Two fracture models were tested--a 3 cm subtrochanteric defect and an 8 cm midshaft defect. Results of the testing revealed the three interlocking nails to be comparable to each other and superior to Ender nails in bending and torsion. However, the distally bolted locked nails (K-S, G-K) resisted significantly higher loads than either the distally bladed locked nail (B-W) or Ender nails when tested to failure by axial loading.
对设计用于治疗股骨干粉碎性骨折的市售锁定髓内钉系统的生物力学性能进行了比较和评估。将恩德斯髓内钉以及三种形式的交锁髓内钉，即布鲁克-威尔斯（B-W）钉、克莱姆-舍尔曼哈（K-S）钉和格罗斯-肯普夫（G-K）钉植入尸体股骨中。对股骨进行扭转、弯曲和轴向加载直至破坏试验。测试了两种骨折模型——一种3厘米的转子下缺损和一种8厘米的骨干中段缺损。测试结果显示，三种交锁髓内钉在弯曲和扭转方面彼此相当，且优于恩德斯髓内钉。然而，在轴向加载直至破坏测试中，远端带螺栓的锁定髓内钉（K-S钉、G-K钉）比远端带刃的锁定髓内钉（B-W钉）或恩德斯髓内钉能承受显著更高的载荷。
