High Purity Medical Tantalum Rod

Benefits of high purity medical tantalum rods: Not only is tantalum harmless to the human body, but human muscles can also grow on it. For example, porous tantalum coatings are used in the construction of orthopedic implants because tantalum can form a direct bond between hard tissue. This is medically called bio-soluble.

Porous tantalum rods are used in medicine as porous tantalum rods. Porous tantalum rods are honeycomb-like three-dimensional rod-like structures characterized by the cancellous structure of human bone, with an average pore size of 430 nm and a porosity of 75 to 80. 110 GPa), thus avoiding stress masking effects. The porous tantalum rods were prepared by Zimmer. Porous tantalum rod implantation is mainly used for the treatment of early to mid-stage ischemic necrosis of the femoral head. Femoral head necrosis is a disease affecting the function of the femoral head due to the destruction of blood flows in the head, which can occur at any age, but mostly in young people. For the treatment of early femoral head necrosis, the main methods are to reduce the pressure in the femoral head, increase the blood supply of the femoral head, and prevent or slow down the deformation of the femoral head. Porous tantalum rods have a good supporting effect on the area of femoral head necrosis, avoiding femoral head collapse, and have the potential to recanalize the ischemic necrotic area of the femoral head. Porous tantalum can promote cell proliferation and improve the osteogenic capacity of osteoblasts. Clinical trials have shown that the early clinical results of tantalum metal implants for early femoral head necrosis are satisfactory, and the postoperative success rate is significantly higher than that of fibular bone grafting. Compared with traditional surgery, porous tantalum rod implantation has the advantages of simple operation, short operation time (average operation time is 36 min), less bleeding (average bleeding is 70 mL), less trauma, quick postoperative recovery, and short hospitalization time (average is l0 d). Therefore, tantalum rod implantation provides a new option for clinical treatment of early femoral head necrosis.

In our country, aseptic necrosis of the femoral head is a common disease, and its population is very large, ranking first in the world. The early clinical manifestation is hip joint pain, the late femoral head collapse can be manifested as severe pain in the hip joint, obstacles to travel, and seriously affecting the quality of life of patients. There are many methods of quality aseptic necrosis of the femoral head, including drug and surgical treatment, but the efficacy is uncertain. At present, there are many methods to treat osteonecrosis of the femoral head according to different stages in domestic hospitals, especially for patients with early osteonecrosis of the femoral head, pure tantalum rods are implanted, and the effect of early treatment of femoral head necrosis is good.

 The rod is made of tantalum metal. It has a large hole spacing, similar to that of human bone trabeculae. The elasticity of the rod is similar to that of human bone, and the rod has good Biocompatibility, therefore also known as the metal bone trabecula, it can make the human body bone tissue good grow into the metal pure tantalum rod of the gap so that the human bone and the metal tantalum rod integrated, this is good support for the femoral head that is about to collapse. Using this characteristic, the time of femoral head collapse can be delayed, the time of total hip replacement can be delayed, and even the possibility of a total hip replacement can be avoided.

 The reconstruction rod is mainly used to treat stage I or stage II of avascular necrosis of the femoral head. The greatest advantage of the operation is that the trauma is small, only a small incision is needed on the outside of the thigh, and a pure tantalum rod is put into the body, in addition, the operation is guided by fluoroscopy, and the pure tantalum rod can be accurately placed in the required position to achieve good biological fixation and mechanical support.
