Trauma Cannulated Screw
Cannulated screw is a common internal fixation device in orthopedic surgery.
Working process
During the operation, the Kirschner wire with the hole matching the hollow screw is first drilled into the bone of the fracture site, and then the hollow screw is screwed into the fracture site through the guidance of the Kirschner wire. Finally, the Kirschner wire is pulled out to complete the fixation of the fracture site. In many cases of fracture of the neck and femur, the healing cycle is long, and it usually takes about 30 months to remove the cannulated screws. At this point, the bone and the surface of the cannulated nail are closely connected and firmly connected in the nail path, which leads to defects easily generated by conventional nail removal methods, causing secondary injury at the fracture healing site and causing pain to the patient. Percutaneous cannulated screw internal fixation for femoral neck fractures has the advantages of small trauma, good healing, low rate of femoral head necrosis, and good stability.
