Abstract

The invention discloses a bone carrying device for a large segmental bone defect of a tibia. The device comprises a main intramedullary screw, a fixed support, a plurality of fixed screws, and a plurality of carrying needles capable of moving axially along the main intramedullary screw, wherein the main intramedullary screw can be axially nailed into the sclerotin and has the size matched with that of the anatomical structure of the human tibia; locking holes matched with the common fixed screws are formed in two ends of the main intramedullary screw; fixed screw holes are formed in two ends of the main intramedullary screw; the rear ends of the fixed screws are connected with the fixed support; the front ends of the fixed screws are in matched connection with the fixed screw holes in the main intramedullary screw; one end of each carrying needle is implanted into a bone needing to slip; and the other ends of the carrying needles are connected onto the fixed support.

Description

technical field

[0001] The invention relates to a device for treating the bone defect of large segment of tibia by 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, ...
