Original Title: First Clinical Application of 3D Printed Titanium Alloy Femoral Head Support Rod Imitating Human Bone Structure Sunshine Network-Sunshine News (Ren Weifeng, Dang Jinggang, reporter Xiong Xiwen/Tu), based on the image data of femoral head necrosis area, through digital individualized design, 3D printing of titanium alloy femoral head support rod imitating human bone structure. Recently,Titanium 6Al4V wire, Xijing Hospital successfully implanted a titanium alloy support rod with gradual change of human bone structure into patients with femoral head necrosis, effectively alleviating pain symptoms and improving joint function. After searching, it is the first time in the world to use the gradient support rod imitating human bone structure to treat femoral head necrosis,titanium seamless tube, which provides a new scheme for the treatment of femoral head necrosis. Li Wei (a pseudonym), 42, from Yulin, Shaanxi Province, suffered from left hip pain six months ago, titanium filler rod ,titanium plate gr7, which was significantly aggravated when squatting or tired. However, there has been no targeted treatment, resulting in the aggravation of symptoms and difficulty in walking. After arriving at Xijing Hospital, he was diagnosed as bilateral femoral head necrosis after examination, with a large necrotic area. After consultation, the expert team decided to apply a series of innovative achievements to implant titanium alloy femoral head support rods imitating human bone structure. Before the operation, the Department of Orthopaedics of Xijing Hospital 3D printed the titanium alloy femoral head support rod imitating the human bone structure. The operation was performed by Professor Fan Hongbin, Department of Orthopaedics, Xijing Hospital. Because the lesion destroyed the bone of the weight-bearing part of the femoral head and the necrotic area was large, in addition to the implantation of titanium alloy support rods, artificial bone containing bone marrow stromal cells was also implanted as a filler. According to Professor Fan Hongbin, the whole operation is minimally invasive, the implantation process is smooth, only 30 minutes, avoiding joint replacement, achieving minimally invasive and precise operation, and saving the cost of surgery. On the day of the operation,titanium round bar, the pain around the hip joint was significantly relieved, and the joint function recovered satisfactorily one week after the operation. It is reported that the 3D printing titanium alloy femoral head support rod has been patented by the state, which provides a new solution for the treatment of femoral head necrosis and is expected to benefit more patients with femoral head necrosis in the near future.
