Nonunion & Malunion Fractures

Specialized treatment for fractures that fail to heal properly, focused on restoring alignment, promoting bone healing, and improving function.

What Are Nonunion and Malunion Fractures?

Nonunion and malunion fractures occur when a broken bone does not heal correctly. A nonunion happens when the bone fails to heal completely, while a malunion occurs when the bone heals in an incorrect position. Both conditions can lead to persistent pain, instability, and reduced function.

These complications may develop after severe fractures, inadequate immobilization, poor blood supply, or other healing challenges. Early diagnosis and treatment can help restore proper bone alignment and promote healing.

Causes of Nonunion & Malunion

Several factors may increase the risk of improper fracture healing, including:

  • Severe or complex fractures
  • Poor bone alignment after injury
  • Inadequate immobilization
  • Smoking or tobacco use
  • Poor blood supply to the bone
  • Infection
  • Bone loss
  • High-energy trauma
  • Certain medical conditions
  • Premature return to activity

These factors can interfere with normal bone healing.


Symptoms of Nonunion & Malunion

Patients with nonunion or malunion fractures may experience:

  • Persistent pain after fracture
  • Delayed healing
  • Visible deformity
  • Limited range of motion
  • Instability at fracture site
  • Difficulty bearing weight
  • Swelling or tenderness
  • Weakness in the affected limb

Symptoms often continue beyond expected healing time.


How Nonunion & Malunion Are Diagnosed

Diagnosis involves clinical evaluation and imaging studies. Testing may include:

  • X-rays to evaluate bone healing
  • CT scans for detailed bone assessment
  • MRI in select cases
  • Physical examination
  • Review of prior fracture treatment

These evaluations help determine the severity and treatment approach.


Treatment for Nonunion & Malunion Fractures

Non-Surgical Treatment

In select cases, non-surgical care may help stimulate healing. Treatment may include:

  • Immobilization
  • Bone stimulation therapy
  • Activity modification
  • Nutritional support
  • Physical therapy

Close monitoring is important during recovery.

Surgical Treatment

Many nonunion or malunion fractures require surgery. Surgical options may include:

  • Realignment of the bone
  • Internal fixation with plates or screws
  • Bone grafting
  • Intramedullary rod placement
  • Removal of non-healed bone tissue
  • Fracture reconstruction

Surgical treatment helps restore alignment and promote healing.


Recovery After Treatment

Recovery depends on fracture severity and treatment approach. Rehabilitation may include physical therapy to restore strength, mobility, and function. Healing may take several weeks to months depending on the location and complexity.

Follow-up imaging helps monitor bone healing.


When to See an Orthopedic Specialist

You should seek evaluation if you experience:

  • Fracture pain that does not improve
  • Delayed healing
  • Persistent swelling
  • Deformity after fracture
  • Difficulty bearing weight
  • Limited mobility

Early treatment may help prevent long-term complications.
