INTRAMEDULLARY NAILING SYSTEM OF VARIABLE ANGLE TO TREAT FEMUR FRACTURES

The cephaiomedelfary nailing system of the invention can be used to solve three main problems, namely: reducing fractures, improving assembly biomechanics such that the load axis is as favorable as possible for the fracture line, and preventing femoral neck collapse as well as offset and limb length loss, hence avoiding the possibility of reduced abductor power. The system is based on a specific screw channel geometry and the placement of an additional locking screw, allowing the nail to turn through 360 degrees and facilitating nail Insertion through the screw. 本发明的头状髓内钉系统有助于解决三个主要问题：复位骨折、改善装配生物力学以确保负荷轴尽可能有利于骨碎片、并防止股骨颈塌陷以及偏移和肢体长度损失，从而避免外展肌力量降低的可能性。该系统基于特定的螺钉通道几何形状和设置额外的锁定螺钉，允许钉子360°转动并便于通过螺钉插入钉子。
