What are some risk factors of nonunion?
Several factors increase the risk of nonunion.
- 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.
- Older age.
- Severe anemia.
- Diabetes.
- A low vitamin D level.
- Hypothyroidism.
- Poor nutrition.
How do you fix nonunion?
Treatment. In some cases, a bone stimulator can be used to treat a nonunion. A bone stimulator is a small device that delivers ultrasonic or pulsed electromagnetic waves to a bone to stimulate healing. The stimulator is placed over the skin near the nonunion for between 20 minutes and several ours each day.
What three common things cause nonunion?
Causes for non-healing or non union fracture include:
- Infection at the site of the fracture.
- Inadequate blood supply to the bone.
- Separation of the ends of the bone (during surgery or after surgery)
- Inadequate surgical stabilization of the bone.
What is infected nonunion?
Background: Although definitions vary, infected nonunion has been defined as a state of failure of union and persistence of infection at the fracture site for 6 to 8 months.>).
What is a non union fracture?
What is a Nonunion? 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.
What happens if a broken bone is not treated?
Delayed Union. 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.
Will a non union eventually heal?
Can a nonunion heal on its own?
Nonunion of fracture will not heal on its own and requires further treatment. Failure to treat a nonunion can lead to long-term pain, deformity, and loss of function in the affected area.
What is the 5th metatarsal?
The fifth metatarsal is the long bone on the outside of the foot that connects to the small toe. Fracture are common in this bone, but can happen in different areas.
What is Masquelet technique?
Abstract. Masquelet technique, which is the use of a temporary cement spacer followed by staged bone grafting, is a recent treatment strategy to manage a posttraumatic bone defect.
How do you treat a non healing fracture?
Most nonunions require surgery. Surgical treatment of nonunion is usually focused on three goals: Establishing a healthy vascular area of bone and soft tissue around the fracture site. This is accomplished by removal of any poorly dead bone or poorly vascularized tissue or scar from the fracture site.
How do you classify non-infected nonunion?
CLASSIFICATION OF NON-INFECTED NON-UNION HYPERTROHIC NON UNION Hypervascular nonunions have shown uptake of strontium-85, which indicates a rich blood supply in the ends of the fragments ATROPHIC NON UNION strontium-85 uptake in these nonunions indicate a poor blood supply in the ends of the fragments 6.
What are the causes of nonunion?

What are the signs and symptoms of chronic infection and nonunion?
3 Diagnosis of chronic infection and infected nonunion 3.1 Clinical and laboratory findings Chronic discharge, pain, erythema (and rarely edema) are typical clinical findings. Discharge is often intermittent and localized in an area of scar tissue, limiting the possibilities of revision.
What is the meaning of non union?
