Description

technical field

[0001] The invention relates to a device for treating large-segment bone defects using bone transport. Background technique

[0002] A large segmental defect of a long bone is one in which the fracture does not heal spontaneously or only regenerates 10% of the bone, typically 2-3 times the diameter of the involved long bone. Large-segment bone defects are usually caused by high-energy trauma, infection, tumors, etc., often accompanied by limb shortening, deformity, osteomyelitis, muscle atrophy, and stiffness of adjacent joints. Its repair treatment has always been one of the biggest problems in the field of orthopedics. According to statistics, in Germany, bone graft surgery is one of the top 50 treatments that patients receive most frequently; in the United States, about 800,000 patients need bone graft surgery every year; 3 million cases; large bone defects have brought huge physical and mental injuries and economic burdens to patients, so how to solve th...
