The advantages of radial tuberosity replacement mainly include the ability to make the elbow joint more stable and prevent radial displacement. The disadvantages are the poor resistance of the prosthesis to infection, susceptibility to periprosthetic trauma, and so on. The specific advantages are as follows: 1. Stabilization of the elbow joint: For severe trauma to the radial tuberosity, radial tuberosity resection has often been used in the past. However, this treatment can lead to localized bone defects, which in turn make the elbow joint unstable. If radial tuberosity replacement is adopted for such patients, it can restore the original anatomical structure, make the elbow joint more stable, and prevent the elbow joint from loosening or osteoarthritis of the elbow joint. 2. Prevent radial displacement: patients with radial tuberosity resection, due to the existence of bone defects in the upper segment, under the continuous stimulation of external force, the radius may gradually appear to be displaced, which may lead to local deformity. In contrast, patients who have undergone radial tuberosity replacement have a much lower probability of this occurring due to the ability to keep the radius stable. The specific disadvantages are as follows: 1. Poor resistance of the prosthesis to infection: the implanted prosthesis is, after all, a foreign body. Once the septic infection occurs around the prosthesis, it is very easy to cause a large number of pathogenic bacteria adhering around the prosthesis. This makes the infection worse and more difficult to treat. In this case, the implanted prosthesis must be removed. 2. Periprosthetic injuries can easily occur. After implanting this kind of prosthesis, if the patient suffers another injury, due to the difference in strength between the prosthesis and the surrounding bone, it is very easy to cause periprosthetic fracture or even dislocation of the prosthesis.
