What are the risk factors for broken bones not healing?
In some cases, certain risk factors make it more likely that a bone will fail to heal. When a broken bone fails to heal it is called a "nonunion." A "delayed union" is when a fracture takes longer than usual to heal. For bone healing to happen, the bone needs adequate stability and blood supply. Good nutrition also plays a role in bone healing.
What does it mean when a fracture does not heal?
Table of Contents. A nonunion occurs when a broken bone does not heal. Bones have a tremendous capacity for healing themselves, and with proper treatment, most all fractures will heal without complication. However, some fractured bones have difficulty healing.
Why do bones take so long to heal?
In some cases, certain risk factors make it more likely that a bone will fail to heal. When a broken bone fails to heal it is called a "nonunion." A "delayed union" is when a fracture takes longer than usual to heal. Bone Healing For bone healing to happen, the bone needs adequate stability and blood supply.
What happens if a bone isn’t set properly?
It is possible that when a bone is set, it isn’t set exactly right. This is why follow-up appointments are very important, so the doctors can monitor the progress of the healing. When a bone doesn’t heal properly, this is called a malunion. In cases where the bone heals completely when it hasn’t been properly set, there are a few issues of concern.
What happens if a bone doesn't heal properly?
If the two ends of the broken bone are not lined up properly, the bone can heal with a deformity called a malunion. A malunion fracture occurs when a large space between the displaced ends of the bone have been filled in by new bone.
Why do some bones not heal?
When the broken bone fails to heal it is called a “nonunion.” For bone healing to happen, the bone needs adequate stability and blood supply. Nonunions happen when the bone lacks adequate stability and/or blood flow. Determining the cause of a nonunion is critical to determining the proper treatment.
Can you live with a nonunion fracture?
But for 5–10% of individuals with a broken bone, the fracture will fail to heal under the usual treatment. The prolonged pain and disability caused by these non-union bone fractures can have profoundly negative consequences in many areas of life.
Can bones heal without treatment?
Bones are very flexible and can withstand a lot of physical force. However, if the force is too great, bones can break. A broken bone or fracture can repair itself, provided that the conditions are right for the break to heal completely.
What helps bones heal quickly?
The three key steps to faster bone healing are:Alignment of the broken bone fragments.Stability and support at the fracture site through immobilization.Healthy lifestyle choices that promote healing.
What foods help broken bones heal faster?
Iron helps your body make collagen to rebuild bone. It also plays a part in getting oxygen into your bones to help them heal. Good sources: Red meat, dark-meat chicken or turkey, oily fish, eggs, dried fruits, leafy green veggies, whole-grain breads, and fortified cereals.
Can a nonunion heal without surgery?
Some nonunions can be treated nonsurgically. The most common nonsurgical treatment is a bone stimulator. This small device delivers ultrasonic or pulsed electromagnetic waves that stimulate healing The patient places the stimulator on the skin over the nonunion from 20 minutes to several hours daily.
How long can a delayed union take to heal?
Most fractured bones in adults heal within 3-6 months. A nonunion, is when a bone has not healed within 6-9 months. The healing process at this point has stopped and further progress is unlikely.
Can nonunion be fixed?
Many surgeons will treat nonunions by resetting the bone with internal fixation, using plates, screws or nails to keep the broken ends of the bone lined up with each other (reduced) and adding bone graft to improve healing at the fracture site.
Do bones hurt as they heal?
Sub-Acute Pain While the Bone is Healing After about a week or two, the worst of the pain will be over. What happens next is that the fractured bone and the soft tissue around it start to heal. This takes a couple of weeks and is called subacute pain.

Many people who fracture will eventually heal and recover to the point where they no longer experience any pain. However, some people may continue to experience pain long after the fracture and soft tissues have healed.
What causes bone nonunion?
Causes. Nonunions happen when the bone lacks adequate stability, blood flow, or both. They also are more likely if the bone breaks from a high-energy injury, such as from a car wreck, because severe injuries often impair blood supply to the broken bone.
Can malunion be fixed?
Malunion treatment Treatment of a malunion often depends on how the injury occurred. If a bone is misshapen enough to cause a disfigurement, you may need surgery to repair or correct it. Correcting the alignment of the bone is more important if it will cause too much stress on a joint that attaches to that bone.
Why Do broken bones Hurt years later?
Some people may continue to experience pain long after the fracture and soft tissues have finished healing. This is what we call chronic pain. Chronic pain may be caused by nerve damage, the development of scar tissue, aggravation of underlying arthritis, or other causes.
What should you drink to make your bones stronger?
Milk. Fortified soy and other fortified plant-based beverages. Fatty fish like salmon and sardines.
Why is malunion fracture so common?
The most common cause of malunion fracture is because it didn’t receive the correct treatment, or the patient didn’t follow the instructions properly after the fracture cast. In the past, the most common cause used to be non-operative treatment with a cast. Never taking medical treatment for the broken bone.
Why does malunion cause pain?
It may be due to improper alignment or wasn’t set correctly, or the bone twisted itself by any means and healed in that position. Malunion may lead to shorter bone length than usual, twisted bones or bent bones.
What are the common fractures that result in malunion?
Some of the common fractures in the body that might result in malunion are wrist fractures (distal radius), hand bones fractures (metacarpals), and fractures to fingers or thumbs (phalanges) and foot & ankle fractures.
Can a broken bone heal?
If you had a fracture, most of the time it heals properly with proper treatment and without any complications. Occasionally, broken bones may heal in the wrong direction, forming a “malunion” even after treatment. This mal-alignment of bones can cause pain and various cosmetic problems as well.
Why is it important to follow up on a bone?
This is why follow-up appointments are very important, so the doctors can monitor the progress of the healing . When a bone doesn’t heal properly, this is called a malunion. In cases where the bone heals completely when it hasn’t been properly set, there are a few issues of concern. The bone may not be completely straight;
Is a bone straight?
The bone may not be completely straight; it may have turned or twisted a bit during the healing process. The bone may also end up being shorter than it would have been had it not be broken. This may be a very small difference or it may be noticeable.
What happens if you break a bone and it is not set properly?
Separation of the fractured ends of the bone: The bones may not have been set close enough for a union, or may have separated after stabilization. Inadequate stabilization of the fracture : Stabilization is one of the key parts of treating broken bones. If the fracture wasn't able to be set properly, a nonunion might result.
Why are broken bones considered nonunion?
The reason is that the blood flow to these bones is poor even in normal daily life, and therefore, they are a 'set-up' for a nonunion.
What are the problems with nonunion bones?
The problem broken bones for nonunion include: Scaphoid fractures. Talus fractures. Femoral neck fractures. Fifth metatarsal ("Jones") fractures.
What to do if you feel pain after a fracture?
Your doctor will do imaging studies and look for a gap at the fracture site. She might follow up at intervals to see if healing progresses over months. She'll look for the cause with tests for anemia, infection, and diabetes. 1
How to treat a fractured pelvis?
Treatment may involve surgery to remove the infection, to better stabilize the fracture, or to stimulate bone growth with bone graft. If the cause is a lack of good stabilization, you may need internal fixation with metal plates, rods, and screws. External fixation with a rigid frame is used for some nonunions. Bone grafts may use your own bone tissue, often from the iliac crest of the pelvis, or from a donor. 1
What is a nonunion fracture?
A nonunion occurs when a broken bone does not heal. Bones have a tremendous capacity for healing themselves, and with proper treatment, most all fractures will heal without complication. However, some fractured bones have difficulty healing. When a bone is slow to heal, we call this a "delayed union.". When a bone does not heal, we call this ...
What fills the space created by the fracture?
haemorrhage: blood and surrounding cells fill the space created by the fracture.
What is fracture displacement?
fracture displacement: the bone heals, but in an incorrect alignment. This gets partially corrected over time, but the correction mechanism is limited, especially in adults.
Can leg length discrepancy cause back pain?
Dr. Haller: Yeah, really, patients can become symptomatic for a couple centimeters of leg length discrepancy. And most commonly, the symptoms associated with that are back pain, hip pain, and if it's also, it can get some knee pain if it's in the tibia bone or shin bone.
Can you rotate a bone?
Dr. Haller: It's pretty similar. Again, you do an osteotomy or a cut or re-break the bone and you can rotate the bone and fix it with plate and screws or with a rod down the middle of the bone.
Can family members tell if a bone is rotated in or out?
Dr. Haller: Most commonly people will present saying that their family members noticed that they have either a limb length discrepancy or they walk funny or one leg is rotated in or out. Normally it's family members that notice the most and will point the patient to either an orthopedic surgeon or general practitioner to take an X-ray. And then it can be pretty obvious that the bone is not quite the same as the other side.
Is One Leg Longer Than the Other?
Dr. Haller: Commonly you do see a leg length discrepancy with these, and that's picked up on the long standing X-ray.
What is the nonunion rate of a bone?
The researchers found a nonunion rate of 4.93% overall with substantial variation from bone to bone. The lowest nonunion bone rates were in metacarpal at 1.47% and radius at 2.10%. The highest nonunion rates were in scaphoid at 15.46%, tibia+fibula at 13.95%, and femur at 13.86%.
How many fractures did the National Team of Orthopaedic Surgeons examine?
To better understand the risk factors that contribute to the failure of fractured bones to heal, a national team of orthopaedic surgeons examined health records from 90.1 million patients. Their goal was to describe the epidemiology of fracture nonunion in adults using the information available to physicians at patient presentation. They focused on patients 18-63 years old, representing 6,725 patients with 309,330 fractures. They researched risk factors likely to be of general concern to orthopaedic surgeons and pooled data to identify 45 variables of interest.
How Does a Bone Heal?
The bone healing process is the same in all broken bones. This is true whether a bone has been cut as part of a surgical procedure or fractured through an injury.
What Can Hinder Bone Healing?
A wide variety of factors can slow down the healing process. These include:
How Long Does Bone Healing Take?
Bone generally takes six to 12 weeks to heal to a significant degree. In general, children's bones heal faster than those of adults. The foot and ankle surgeon will determine when the patient is ready to bear weight on the area. This will depend on the location and severity of the fracture, the type of surgical procedure performed and other considerations.
What Helps Promote Bone Healing?
The surgeon may offer advice on diet and nutritional supplements that are essential to bone growth. Smoking cessation and adequate control of blood sugar levels in people living with diabetes are important. Smoking and high glucose levels interfere with bone healing.
Why is immobilization important for fractured bones?
For all patients with fractured bones, immobilization is a critical part of treatment because any movement of bone fragments slows down the initial healing process. Depending on the type of fracture or surgical procedure, the surgeon may use some form of fixation (such as screws, plates or wires) on the fractured bone and/or a cast to keep ...
What is bone remodeling?
In remodeling, bone continues to form and becomes compact, returning to its original shape. In addition, blood circulation in the area improves. Once adequate bone healing has occurred, weightbearing (such as standing or walking) encourages bone remodeling.
What is the process of producing bone?
This provides the initial structural stability and framework for producing new bone. Bone production begins when the clotted blood formed by inflammation is replaced with fibrous tissue and cartilage (known as soft callus).
Why does bone not heal?
These chemicals are called growth factors . When a bone breaks, they are normally produced in the body in a certain sequence. Other chemicals can decrease the chance of the bone healing. Researchers are concentrating on synthesizing these chemicals and determining the ideal way either to block the negative factors or increase the positive factors to the injured bone. Someday, physicians may be able to inject the chemicals directly into the nonunion to promote healing.
What is it called when a broken bone fails to heal?
In some cases, certain risk factors make it more likely that a bone will fail to heal. When a broken bone fails to heal it is called a "nonunion.". A "delayed union" is when a fracture takes longer than usual to heal.
What is bone graft?
Bone grafts also provide fresh bone cells and the naturally occurring chemicals the body needs for bone healing. During the procedure, a surgeon makes an incision and removes (harvests) pieces of bone from different areas on the patient. These are then transplanted to the nonunion site.
How long does pain last after a nonunion?
Patients with nonunions usually feel pain at the site of the break long after the initial pain of the fracture disappears. This pain may last months, or even years. It may be constant, or it may occur only when the broken arm or leg is used.
Can a nonunion happen?
Blood Supply. Nonunions are more likely to happen if the injured bone has a limited blood supply. Some bones, such as toe bones, have inherent stability and excellent blood supply. They can be expected to heal with minimal treatment.
Does smoking gum cause bone to heal?
Use of tobacco or nicotine in any form (smoking, chewing tobacco, and use of nicotine gum or patches) inhibits bone healing and increase the chance of a nonunion
Can bone grafts be used to repair nonunion?
Although bone graft substitutes do not provide the fresh bone cells needed for normal healing, they do provide a scaffold chemicals needed for growth. Depending on the type of nonunion, any of the above materials, or a combination of materials, may be used to fix the nonunion.
