Reduction (orthopedic procedure)

Sometimes a bone breaks. It can move out of place. A doctor can fix this. This is called a reduction.

Doctors use pictures to see the bone.

They look at the bone before and after. This shows if it is straight.

In one way, the doctor does not cut the skin. They move the bone from the outside. This is a closed reduction.

In another way, the doctor must cut the skin. This is an open reduction. They might use tools to hold the bone.

Doctors also help with the pain. They use medicine to help you relax. This helps the bone heal well.

Sometimes a broken bone moves out of place. This is called a displaced fracture. A doctor can fix this using a reduction. This is a way to put bones back where they belong. A reduction can also fix a dislocation. That is when two bones in a joint move apart.

Doctors use X-rays to see the bones. They take one picture before they start. They take another picture after they finish. This shows if the bones are straight.

There are two main ways to do this. In a closed reduction, the doctor does not cut the skin. They move the bone from the outside. In an open reduction, the doctor must cut the skin. This is a surgery. They might use hardware to hold the bone in place. This is called fixation.

Doctors use medicine to help with pain. They may use local anesthesia to numb one spot. This helps the patient stay calm and relaxed. This makes it easier to move the bones. Some people might need general anesthesia to sleep during surgery.

Sometimes a broken bone moves out of place. This is called a displaced fracture. A doctor must fix this so the body can heal well. This medical task is called a reduction. It is also known as setting the bone. A reduction can also fix a dislocation. A dislocation happens when two bones in a joint move apart. Doctors want the bones to reach their normal anatomical position.

Doctors follow a few steps to make the bones straight. First, they use X-ray imaging to see the bones. They take a picture before they start the work. This confirms how the bones are misaligned. After the reduction, they take another X-ray. This second picture shows if the bones are in the right spot. For dislocations, doctors often use traction. Traction is a sustained pulling pressure on the bone. This helps relax the muscles and creates space.

They can use human strength or pulleys and weights.

There are two main ways to do a reduction. The first way is called a closed reduction. In this way, the doctor moves the bone from the outside. They do not have to open the skin. This is not a surgery. It often happens in an emergency department. A common example is a distal radial fracture in the wrist. The second way is an open reduction. This is a surgical procedure where the skin is opened. Doctors move the bone from the inside. They might use hardware for fixation to hold the bone.

Medicine helps the patient stay calm and comfortable. For closed reductions, doctors use local anesthesia or sedatives. They might use a hematoma block for forearm fractures. This is when they inject lidocaine into the fracture site. They use ultrasound to guide the needle. For open reductions, an anesthesiologist uses general anesthesia. This makes the patient sleep in an operating room. Doctors often use drugs like midazolam or fentanyl. In adults, they might use propofol or etomidate. These help reduce stress and relax the body.

Reductions are very important for healing properly. However, there are some risks to keep in mind. A reduction might cause damage to nerves or blood vessels. Sometimes the reduction is not successful on the first try. This might mean the doctor needs more medicine or surgery. Open reductions also carry risks like infection or hardware failure. After a closed reduction, a person may feel pain. This pain usually lasts for two to three weeks. It can stay as mild pain for up to six weeks.

Reduction is a medical procedure used to restore correct anatomical alignment. This process is necessary when an injury causes a fracture or a dislocation. A fracture occurs when a bone breaks into segments. If these segments are no longer in their proper place, it is called a displaced fracture. A dislocation is different because it involves a joint. It happens when two connecting bones move out of their normal position. Doctors must perform a reduction to ensure effective healing for both types of injuries. Some medical providers may also call this process "setting the bone."

To ensure the bones are placed correctly, doctors use specific steps. First, they use confirmatory imaging, such as an X-ray, before the procedure. This imaging confirms exactly how the bones are misaligned. Once the reduction is finished, the medical team takes another X-ray. This second image confirms that the bones have achieved their proper anatomical positioning. This careful process of checking before and after is vital for accuracy.

There are two main categories of fracture reductions: closed and open. A closed reduction is when alignment is achieved through external manipulation. This means the doctor moves the bone from the outside without opening the skin. Because it does not require an incision, it is not considered a surgical procedure. These are often performed in an emergency department. A common example of a bone requiring this is a distal radial fracture, which is a break in the wrist.

An open reduction is a different, more complex approach. This is a surgical procedure where the skin is opened to allow for internal manipulation. During an open reduction, the doctor works directly on the bone. After the fracture site is reduced, doctors often use a process called fixation. Fixation involves using fixed hardware to maintain the bone's alignment while it heals. This can include internal fixation (ORIF) or external fixation (OREF). However, some fractures may not require fixation even after an open reduction.

When reducing a dislocation, doctors often apply a technique called traction. Traction is a sustained pulling pressure applied to the distal bone of the dislocated joint. This pressure helps to relax the surrounding musculature. By relaxing the muscles, the doctor creates space for the bone to move back into its anatomical position.

This pulling can be done using human strength. Alternatively, a system of pulleys and weights can be used to apply the necessary force.

Managing pain and stress is a major part of the procedure. For open reductions, an anesthesiologist typically administers general anesthesia in an operating room. Closed reductions often use multimodal pain medications, sedatives, or local anesthesia. Doctors frequently aim for a state of conscious sedation. This helps reduce patient stress and relaxes the body for better manipulation. In children, ketamine and midazolam are common choices, often paired with fentanyl. Adults may receive propofol, midazolam, etomidate, or fentanyl. For forearm fractures, doctors might use a hematoma block. This involves injecting lidocaine into the fracture site using ultrasound guidance.

While reductions are essential, they do carry certain risks and complications. There is a possibility of further damage to the fracture or the dislocation itself. The procedure could also damage surrounding structures like nerves, muscles, or blood vessels. If a reduction is unsuccessful, doctors may need multiple attempts. This could lead to a longer need for medication or a switch to surgery. Open reductions specifically carry risks of infection, hardware failure, or adverse reactions to general anesthesia. After a closed reduction, patients should expect pain for two to three weeks. This may continue as milder pain for up to six weeks.
