On April 19, 2022, the Department of Osteopathy and Oncology of Xi’an Honghui Hospital successfully performed resection of a humeral malignant tumor for a 13-year-old patient3D printingProsthetic reconstruction.
Xiaoxin (pseudonym) suffered from a tumor in the middle and upper segment of the right humerus. After several tossing and turning, she went to Xi’an Red Cross Hospital for medical treatment. The biopsy was diagnosed as osteosarcoma of the middle and upper segment of the right humerus.
According to Yang Tuanmin of the Department of Osteopathy and Oncology, osteosarcoma is a highly malignant primary tumor of the long bones of children. The treatment principle is as follows:OperationCombined chemotherapy and radiotherapy.Due to the large tumor size, nobiologyReconstruction is possible, and there is no related tumor prosthesis. Limb salvage is very difficult and has always been a problem in the industry, so amputation is generally chosen.
For a 13-year-old girl, amputation will inevitably bring a huge shadow to the child’s mind. At the same time, after Xiaoxin’s parents expressed their strong willingness to save the limb, they finally decided to choose the limb salvage plan. In response to Xiaoxin’s specific condition, Yang Tuanmin of the Department of Osteopathy and Oncology was appointed to lead the team members Wang Zhichou, Huang Guilin, Shao Yuxiong, Li Zhengzheng and other attending physicians. After careful case discussion, it was decided that after neoadjuvant chemotherapy, the right humerus bone tumor was surgically removed. .play3D printingexistorthopedicsField advantages, design individualized 3D printed titanium alloy prosthesis of upper humerus, combined with artificial shoulder joint technology, retain part of normal bone and length of affected limb, and realize humerus reconstruction.
Preoperatively, through precise computer-aided design, imaging data mirroring, and titanium alloy 3D printing, the 3D printed imitation bone trabecular end and osteotomy end of the prosthesis can fit perfectly, enabling bone ingrowth and achieving biological reconstruction. Effect. This preserves the joint and reduces the incidence of prosthesis loosening. At the same time, the void structure is conducive to soft tissue ingrowth. On the day of the operation, with the cooperation of the Department of Anesthesiology, Yang Tuanmin appointed the team to work closely and perform precise operations to complete a series of operations such as tumor resection, 3D printing prosthesis implantation, and soft tissue reconstruction. It took 3 hours to successfully complete the hospital’s first 3D-printed humeral prosthesis for the treatment of humeral osteosarcoma.
At present, Xiaoxin is in good health and is doing active functional exercises, striving to achieve a normal life as soon as possible.
