Improperly Healed Broken Bones
A malunion fracture is a condition that occurs when the ends of a broken bone do not line up properly as the bone heals. The condition can cause a bone that is twisted, rotated or bent. It may change the length and make the bone shorter than normal. If left untreated, malunion fractures can cause joint instability, arthritis and loss of function.
Malunion fractures happen more often in severe breaks than in minor fractures. They can result when the fractured bone does not get enough oxygen or nutrients to promote healing. Insufficient stability during healing can also lead to malunion fractures.
Symptoms, Diagnosis and Outlook
Malunion fractures can occur in any broken bone. Symptoms tend to begin after the bone’s initial healing and vary depending on the affected bone and severity of the malunion.
Common symptoms include:
- Pain, discomfort and bone tenderness
- Swelling and tenderness in the affected area
- Visible deformity like twisted, bent or shortened bone
- Difficulty bearing weight
- Decreased function
- Inability to flex the affected joint
To diagnose a malunion fracture, the orthopaedic specialists at Penn State Health conduct a thorough physical examination and review your medical history. Additional testing may include:
- Computed tomography (CT) scan
- Magnetic resonance imaging (MRI) scan
- Range of motion and symmetry assessment
With proper treatment, many malunion fractures are able to heal correctly. Depending on the location and severity of the break, you may require physical therapy to regain muscle strength, range of motion and function.
