Fracture fixation helps in stabilizing the fractured bone, returning to mobility and complete functioning, and enabling faster healing of the damaged bone. Fractures are usually treated in two ways – conservatively or with internal or external fixation. In treating a fracture conservatively, it involves closed reduction for restoring the alignment of the bone and immobilising the reduced fracture fragments in a splints, brace or a plaster cast.
Internal fixation involves usage of different devices that are characterized into pins, wires, plates, screws, and intramedullary nails or rods. In some cases, clamps and staples are also used for fracture fixation or osteotomy.
Talking about external fixators, they are based on the splinting principle and are of three types – ring fixator, uniplanar fixator, and hybrid fixator.
When long bones are fractured, the most appropriate way to get the broken bone fragments back together is by inserting a nail or rod through the hollow passage in the middle of the bone that usually has some marrow. To keep the fracture from rotating or shortening, screws are attached at both ends of the rods. Screws also help to hold the rods in place until complete healing of the fractured bone. Rods/nails and screws may be left inside post healing but removed surgically in children or young adults.
External fixators work as a stabilizing frame that holds the damaged bones in place. Metal pins or screws are inserted into the broken bone through tiny incisions made in the skin and muscle. The screws and pins are attached to a bar on the exterior of the skin. As the pins are inserted into the damaged bone, these fixators differ from splints and casts which depend entirely on external support.
In most cases, this kind of fixation is performed as a temporary solution for the fractures especially when there is a loss or skin and tissue over the fracture. As they are applied easily, external fixators are mostly used for patients having multiple injuries and are unable to hold for longer surgery due to co-morbid conditions and injuries. Using external fixator to treat fractures provides perfect temporary stability. It works well for the period during which the patient gets prepared for the main surgery.
Certain things are considered while choosing the right internal or external fixators for treating fractures, such as the location, age of the patient, type of fracture, medical history of the patient, etc. If the chosen fixators are not compatible with the body, it may lead to infection and other rare side-effects.
