Are Bones Repaired By Internal Fixation Weaker After They Heal

A broken bone must exist carefully stabilized and supported until it is strong enough to handle the trunk's weight and movement. Until the last century, providers relied on casts and splints to back up and stabilize the bone from outside the trunk. Today, advances in research and surgery allow providers to internally prepare and stabilize fractured basic.

During a surgical procedure to set a fracture, the bone fragments are first repositioned (reduced) into their normal alignment. They are held together with special implants, such as plates, screws, nails, and wires.

Internal fixation allows shorter hospital stays, enables patients to return to normal activities before, and reduces the incidence of nonunion and malunion (healing in improper position) of cleaved bones.

The implants used for internal fixation are fabricated from stainless steel and titanium, which are durable and strong. If a joint needs to exist replaced, rather than fixed, these implants may be made of cobalt and chrome. Implants are compatible with the body and rarely cause an allergic reaction.

How to plates assist care for cleaved bones?

Plates are like internal splints that concord the broken pieces of os together. They are attached to the os with screws. Plates may be left in place after healing is complete, or they may be removed (in select cases).

How exercise screws aid treat broken bones?

Screws are used for internal fixation more often than any other type of implant. Although the screw is a simple device, at that place are unlike designs based on the blazon of fracture and how the screw will be used. Screws come in different sizes for use with bones of different sizes. Screws tin exist used lone to hold a fracture, as well as with plates, rods, or nails. After the bone heals, screws may exist either left in place or removed.

How do screws and rods aid treat broken basic?

In some fractures of the long bones the best way to hold the bone pieces together is by inserting a rod or nail through the hollow center of the bone that normally contains some marrow. Screws at each cease of the rod are used to proceed the fracture from shortening or rotating, and also agree the rod in place until the fracture has healed. Rods and screws may exist left in the bone after healing is complete. This is the method used to treat the majority of fractures in the femur (thighbone) and tibia (shinbone).

How exercise wires and pins aid treat broken basic?

Wires are frequently used to pin the bones back together. They are often used to concur together pieces of os that are as well small to exist fixed with screws. In many cases, they are used in conjunction with other forms of internal fixation, but they can exist used alone to treat fractures of pocket-sized bones, such every bit those found in the hand or human foot. Wires are normally removed after a sure amount of time, but may be left in permanently for some fractures.
