Pseudoarthrosis: Signs, Causes, And How To Treat
Pseudoarthrosis, also known as a false joint, occurs when a bone fracture fails to heal properly. This can result from various factors, such as poor blood supply, infection, or inadequate support during the healing process. Without proper treatment, pseudoarthrosis can lead to ongoing pain and limited mobility.
It is essential to consult with a healthcare provider for an accurate diagnosis and appropriate management. By understanding the causes of pseudoarthrosis, individuals can take proactive steps to promote healing and prevent further complications.
Symptoms of Pseudoarthrosis
You may notice difficulty moving the joint, abnormal sensations, and changes in the way you walk or stand. If left untreated, it can lead to deformity or disability. Seeking medical advice is crucial to address these symptoms and prevent further complications.
- Pain and swelling around the site of a previous bone fracture that doesn't improve with rest or pain medication.
- Difficulty bearing weight on the affected limb due to instability and weakness in the bone.
- Visible deformity or abnormal movement at the site of the injury, such as a noticeable gap between bone ends.
- Persistent tingling or numbness in the area, indicating potential nerve involvement from the non-healed bone.
- Recurring episodes of fracture despite proper healing time, leading to ongoing issues with mobility and function.

Other contributing factors include excessive movement at the fracture site, poor surgical technique, and inadequate postoperative care. These various factors can lead to the failure of bones to heal properly, resulting in pseudoarthrosis.
- Pseudoarthrosis can be caused by inadequate stabilization of the fracture site during the initial treatment, leading to improper bone healing.
- Smoking and poor nutrition can contribute to pseudoarthrosis by impairing the body's ability to form new bone tissue.
- Infection at the fracture site can interfere with the bone healing process and result in the development of pseudoarthrosis.
- Certain medical conditions such as diabetes or osteoporosis can delay or prevent proper bone fusion, increasing the risk of pseudoarthrosis.
- Excessive movement or weight-bearing on the affected bone before it has adequately healed can disrupt the formation of a stable union, resulting in pseudoarthrosis.
Types of Pseudoarthrosis
There are two main types of pseudoarthrosis: hypertrophic and atrophic. Hypertrophic pseudoarthrosis occurs when there is excessive bone formation at the site of a broken bone, leading to instability.
On the other hand, atrophic pseudoarthrosis is characterized by a lack of bone formation, resulting in a non-union of the broken bone. Both types can cause pain and limited mobility, requiring medical attention.
- Hypertrophic pseudoarthrosis is characterized by an excessive formation of fibrous tissue at the site of a non-union fracture, leading to abnormal movement and instability in the affected bone.
- Atrophic pseudoarthrosis occurs when there is a lack of adequate blood supply to the fracture site, resulting in poor bone healing and the formation of a false joint that lacks stability and function.
- Oligotrophic pseudoarthrosis is a type of non-union fracture where there is limited callus formation and inadequate bone bridging, causing persistent pain and impaired mobility in the affected limb.
Risk Factors
Risk factors for pseudoarthrosis include smoking, diabetes, obesity, poor nutrition, advanced age, and certain medical conditions such as osteoporosis and rheumatoid arthritis.
- Smoking is a significant risk factor for pseudoarthrosis, as it can impair blood flow to the bones and hinder the body's ability to heal properly.
- Diabetes can increase the likelihood of pseudoarthrosis due to its impact on blood circulation and the body's ability to fight infections, both crucial factors in bone healing.
- Poor nutrition, particularly a lack of essential nutrients like calcium, vitamin D, and protein, can impede the bone's ability to mend and increase the risk of pseudoarthrosis.
- Obesity puts excess strain on the bones and can interfere with the healing process, making individuals with higher body mass indexes more susceptible to developing pseudoarthrosis.

Diagnosis of Pseudoarthrosis
Your doctor will assess your symptoms, examine the area, and order X-rays or MRI scans to look for signs of incomplete bone healing. A bone scan may also be done to confirm the diagnosis.
- X-rays are commonly used to diagnose pseudoarthrosis by visualizing the affected bone area for signs of non-union or abnormal bone formation.
- CT scans provide detailed cross-sectional images of the bone, allowing healthcare providers to identify any structural abnormalities associated with pseudoarthrosis.
- MRI scans use magnetic fields and radio waves to produce high-resolution images of the bones, soft tissues, and surrounding structures, aiding in the detection of pseudoarthrosis complications.
- Bone scans involve injecting a radioactive tracer into the bloodstream to highlight areas of abnormal bone metabolism, which can help identify pseudoarthrosis.
Treatment for Pseudoarthrosis
Treatment options for pseudoarthrosis include surgery to stabilize the bone, bone grafting to promote healing, and the use of bone stimulators to enhance bone growth. Physical therapy and lifestyle modifications may also be recommended to improve mobility and strength.
- Surgical intervention is a common treatment option for pseudoarthrosis, involving the stabilization of the affected bone with internal fixation hardware such as plates, screws, or rods to promote proper bone healing.
- Bone stimulators, which use electromagnetic fields or ultrasound waves to stimulate bone growth, may be utilized as a non-invasive treatment for pseudoarthrosis to enhance bone fusion.
- Bone grafting procedures, where bone tissue is transplanted from another part of the body or donated bone material is used, can help promote bone fusion and healing in cases of pseudoarthrosis.
