Quick Answer: In Orthopedics, What Is A Malunion?

What is Malunion?

A malunion occurs when a fractured bone heals in an abnormal position, which can lead to impaired function of the bone or limb and make it look like it is ‘bent’. Similarly, a nonunion is the result of a fractured bone failing to heal after an extended period of time – in some cases over a period of 9 to 12 months.

What causes Malunion?

The causes of a malunion are broad, but most often it’s the result of not seeking medical treatment soon enough after a fracture (or not seeking it at all), removing a cast or other immobilizing tool too early, or not aligning bones properly during the immobilization process.

Can a Malunion be fixed?

How long can a union take to heal? Malunion and nonunion fractures can take some time to heal. The exact time of recovery depends on the area of injury and surgery. With the right team of medical professionals, malunion and nonunion fractures can be fixed, and you can return to a normal lifestyle.

How do you know if you have a malunion?

Malunion symptoms include constant pain long after treatment. If severe enough, the condition can cause a deformity and may require surgery to repair or correct it.

Can a displaced bone heal without surgery?

Some fractures stay still enough to heal without a cast or surgical plate. Ribs run parallel to each other, so a fractured rib is supported by the ribs on each side. We also don’t put a bunch of pressure on our ribs, so they heal easily.

What happens if a bone heals wrong?

Broken bones can occasionally heal in the wrong position, forming a “malunion” or “malalignment” after treatment. These misaligned bones can cause further problems and pain in the body.

What type of metal is used for bone repair?

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

What happens if clavicle healed wrong?

As you lift your arm the clavicle elevates rotates and retracts. Thus if your clavicle fractures and heals shortened it can cause abnormal scapula motion and possibly shoulder pain and weakness. The clavicle also protects lung tissue and nerves.

What happens when a fracture doesn’t heal properly?

When a bone fracture is untreated, it can result in either a nonunion or a delayed union. In the former case, the bone doesn’t heal at all, which means that it will remain broken. As a result, swelling, tenderness, and pain will continue to worsen over time.

Can you fix a bone that healed wrong?

In many cases, when a fracture heals in a position that interferes with the use of the involved limb, surgery can be performed to correct it.

What happens if you break a bone and don’t get it fixed?

The broken bone must be properly aligned and held in place, often with a plaster cast, so it heals in the correct position. If you do not receive the correct treatment, you could develop a serious infection or a permanent deformity. You may also have long-term problems with your joints.

What causes bones not to heal?

Causes and Risk Factors Blood brings oxygen, healing cells and growth factors to the bone to allow it to heal. If a fractured bone is left unstable or lacks blood supply, it can lead to a nonunion. Factors including the use of tobacco or nicotine can impede bone healing and increase the risk of nonunion.

Does resetting a bone hurt?

The patient may feel pressure or a crunching sensation but will usually not experience any significant pain.
