Titanium metal, with its unique physical and chemical properties, has shown a wide range of applications in orthopedics. In addition to the wave-formed curved foot riding nail and patellar aggregates introduced in the previous two issues, titanium also plays an important role in a variety of areas such as spinal orthopedic rods, intramedullary pins, intramedullary nails, pressurized splints, and artificial joints.
In spinal orthopedics, titanium-nickel alloy spinal rods have become an important tool in the treatment of scoliosis. The most important features of these rods are their excellent elasticity and recovery. During surgery, the surgeon can fix the titanium-nickel rods to each vertebral spinous process, spreading the force gently and greatly reducing the risk of fracture. After surgery, the patient does not need to be immobilized in a cast, reducing inconvenience and pain during recovery. Even more amazingly, when the titanium-nickel alloy rods are warmed, their restorative power can be utilized to correct scoliosis to a certain curvature. Due to the limitation of the residual curvature of the spine, the titanium-nickel alloy rods do not completely return to the original straight shape after correction, so it still produces continuous orthopedic force on the spine, which ensures the stability and durability of the therapeutic effect.
