Recently, the Tianjin hospital doctor for a 56-year-old man from Heilongjiang Province successfully conducted the first domestic "3D print sternum stalk malignant tumor resection of customized prosthesis functional reconstruction", for its successful removal for many years, has grown into adult Fist-sized rare sternal calcaneal chondrosarcoma, and the use of both intensity, individualized and histologically compatible 3D print custom prosthesis, completely retains the patient's bilateral thoracolumbar joints, shoulder and upper limb function. It is understood that such surgical methods and reconstruction methods, the domestic has not been reported in the literature.
The patient was hit by a tricycle by a tricycle 20 years ago with a sternal pain, but with the pain gone, I did not care. 7 years ago, he found a bulging before the sternum out of the package, but no obvious swelling and pain, still not diagnosis and treatment. 4 months ago, the tumor was significantly increased, accompanied by local pain, increased after the event. He went to Tianjin Hospital, thoracic surgery, was diagnosed with sternal calculi chondrosarcoma, mass has reached the size of human fist.
According to Wang Dongbin, director of the department, surgical resection is the first choice for the treatment of sternal tumors, but the incidence of sternal chondrosarcoma is low, can refer to the literature very little, and the difficulty of the operation is quite large: First, the sternum close to both sides of the clavicle, , The tumor is not active, such a huge malignant tumor can be a complete resection is a difficult; second, the tumor behind the aortic arch and its branches, the left arm and vein were pressure phenomenon, indicating that the tumor may be involved in large blood vessels, Surgery, there is a large risk of bleeding; third, the sternum and mass resection, the bilateral clavicle and sternal body will form a huge defect between, which will cause the chest wall softening collapse, thoracic activity damage and upper limbs, Department of activities disorders, the quality of life of patients will be greatly affected.
Surgery, the doctor carefully operation, careful dissection and treatment of blood vessels, tumor and the rear of the blood vessels were successfully separated one by one, complete removal of the tumor; application of 3D printing technology to simulate the patient's own sternal shape, size, thickness and other customized individual sternum Body, used to repair the thoracic bone resection after chest wall defects, restore chest integrity. In addition, in order to help patients save the cost of surgery, the use of patients with autologous tendon reconstruction of the sternoclavicular joints, to maximize the patient's shoulder and upper limb function, to achieve the functional reconstruction of the bony. Patients after successful rehabilitation, appearance, limb function and ordinary people is no different
