Wire internal fixation

The disadvantage of steel wire is that the fixing effect is small and the application range is correspondingly small. The use of stainless steel wire to fix the oblique or spiral folds of the long backbone is not only easy to break, but also can cause bone absorption outside compression. Periosteal blood flow is impaired, thereby losing fixation and affecting fracture healing. However, the steel wire has the characteristics of thin diameter and bendability, and can be looped or fixed through an artificial bone tunnel, which can effectively maintain the reduction of some fractures, which is its advantage. Stainless steel wire internal fixation is mostly used in the following cases [Figure 1]. 1. Transverse fracture of metatarsal bone; 2. Transverse fracture of olecranon process of ulna; 3. Avulsion fracture of terminal phalanx; 4. As an auxiliary fixation of other internal fixation, to fix free bone pieces (such as intramedullary needle fixation and small bone piece fixation with wire) 5. Unstable cervical fracture and dislocation.
