A closed reduction is a medical procedure that realigns a broken bone or dislocated joint without any surgical incision. Your doctor physically pushes or pulls the bone back into its correct position through the skin, then immobilizes it with a cast or splint so it can heal properly. It’s one of the most common ways fractures are treated, especially when the bone fragments haven’t shifted too far apart or pierced through the skin.
How the Procedure Works
The basic principle is straightforward: a doctor uses their hands to manipulate the bone or joint back into alignment. The main technique involved is called traction, which means applying a steady pulling force along the length of the bone to separate the fragments enough to reposition them. Often, an assistant applies counter-traction (pulling in the opposite direction) to stabilize the limb while the doctor works.
For dislocated joints like shoulders, there are over twenty different maneuvers a doctor might use, each involving some combination of traction, leverage, and rotation. For a shoulder dislocation, this could mean slowly pulling your arm outward while rotating it, or having you lie face down while weights gently pull the joint back into place over 10 to 20 minutes. The specific technique depends on the type and direction of the dislocation.
For fractures, the doctor feels the bone fragments through the skin and applies pressure to guide them back together. The goal is to restore the bone’s natural alignment closely enough that it can heal in the correct position. For a wrist fracture, for example, a successful reduction means the bone shortening is less than 1 millimeter and the bone’s natural angle is restored.
Pain Management During Reduction
Repositioning a bone is painful, so you’ll receive some form of anesthesia beforehand. The approach depends on the fracture’s severity and location. A common first-line option is a hematoma block, where numbing medication is injected directly into the blood that collects around the fracture site. This is simple and quick, though it doesn’t eliminate pain entirely. About 37% of patients given a hematoma block still report significant pain during the procedure.
A nerve block, which numbs the entire region by targeting the nerves supplying that area, tends to work better. Only about 15% of patients receiving a nerve block report significant pain. General anesthesia, where you’re fully unconscious, provides the best conditions for the doctor to work but is generally reserved for complicated cases or situations where an open surgical reduction might be needed. For children, conscious sedation in the emergency department is the most common approach.
When Closed Reduction Is Used
Closed reduction works best for fractures where the bone fragments are still relatively close together, the pieces aren’t rotated out of position, and the surrounding ligaments and soft tissue structures are intact. Ankle fractures, wrist fractures, and many arm fractures in children are commonly treated this way. Joint dislocations, particularly of the shoulder, are almost always treated with closed reduction first.
Several factors determine whether a closed reduction will work or whether surgery (called open reduction) is necessary instead. These include the fracture pattern, how far the bone fragments have shifted, whether the bones are stable enough to hold their position after being realigned, and the patient’s overall health. If a closed reduction can’t achieve or maintain adequate alignment, the next step is typically open reduction with internal fixation, where a surgeon makes an incision and uses plates, screws, or pins to hold the bone in place.
What Happens Afterward
Once the bone is back in position, your doctor will immobilize the area with a cast, splint, or brace. The type and duration depend on the fracture. Ankle fractures, for instance, have historically been treated with a longer cast above the knee for two to three weeks, then switched to a shorter below-the-knee cast for another three to four weeks or more. Knee injuries typically get a long leg splint at a slight bend. Your doctor will take X-rays immediately after the reduction to confirm the bone is properly aligned.
Follow-up imaging is critical because bones can shift out of position during the early weeks of healing. A typical schedule involves a check at two to three weeks. If pins were placed through the skin to help hold the bone (a technique sometimes combined with closed reduction), they’re usually removed around three weeks, with X-rays taken at that visit to confirm alignment and healing. Additional follow-up visits happen as needed based on how the fracture looks.
Success Rates and Risks
Closed reduction has a strong track record, particularly in children. A study of pediatric fractures managed with closed reduction in the emergency department found that 99.2% had a satisfactory final outcome. Success rates were higher for upper extremity fractures (arms and wrists) than lower extremity fractures (legs and ankles), and outcomes improved with the treating doctor’s experience level. Fractures that were successfully reduced on the first attempt were far less likely to need a second manipulation later.
The main risk is that the reduction doesn’t hold, and the bone shifts back out of alignment during healing. This is why follow-up X-rays are so important. More serious but less common complications include nerve or blood vessel injury during the manipulation itself. In children’s elbow fractures, for example, nerve injuries occur in 2% to 6.5% of cases during the reduction or pinning process, with the median nerve being most vulnerable. The artery in the upper arm can also be stretched or trapped during manipulation. These complications are uncommon, and the procedure’s lower overall risk compared to surgery is one of the primary reasons doctors attempt closed reduction first whenever the fracture pattern allows it.
Closed Reduction in Children vs. Adults
Children’s bones are more flexible and have thicker outer coverings, which means their fractures often respond better to closed reduction than adult fractures. Children also have active growth plates that give their bones remarkable remodeling ability. A slight imperfection in alignment that would be unacceptable in an adult may correct itself naturally as a child grows. This is why closed reduction is attempted more aggressively in pediatric patients, and why the success rates are so high. In adults, the margin for acceptable alignment is tighter, and fractures that can’t be reduced precisely enough are more likely to require surgery.
