One, cerclage wire
Cerclage wires are commonly used in cerclage and semi-cerclage.
Indications and Biomechanical Characteristics
Cerclage can increase the stability of long oblique fractures, spiral fractures and comminuted fractures.
The misuse of the cerclage wire may lead to the collapse of the fracture fragment and the loosening of the fracture wire, which will further delay the union.
The change in mechanical tension caused by the wire and the load depends on the degree and alignment of the wire.
Orthopedic wire fixation is usually not used for short oblique or transverse fractures, and should be prohibited when the dog's score is below average.
Apparatus and Auxiliary Materials
The cerclage wire ranges from 0.64mm to 0.1mm, 0.64mm for cats and small dogs, and 0.1mm for large dogs.
Apply
The cerclage wire is wrapped around the bone with a wire guide when a small area of soft tissue is exposed.
2. Related complications
Cerclage wires have been largely replaced by other internal fixation devices, but are still useful for temporary stabilization of long bone fractures.
One concern is that when a wire is used for cerclage, the blood supply to the bone may be reduced because the cerclage compresses the surrounding blood vessels annularly.
