What Happens If A Bone Fracture Is Left Untreated?

Updated October 19 2026

Bone fractures are common after accidents and falls, and they happen to everyone regardless of age. While many fractures can be treated with immobilization and rest, there are many that ignore the symptoms and hope the pain disappears.

This is a huge problem for your health. Leaving a bone fracture untreated can seriously affect a person in many ways, which we will discuss below.

If you suspect a broken bone, do not wait to get help. You can visit our  emergency room near Memorial , without an appointment. .

How Do Bones Heal?

When a bone breaks, the body initiates a complex healing process to repair the damage. The healing process typically involves the following four stages-

  • Hematoma formation
  • Inflammation
  • Callus formation
  • Remodeling

A blood clot forms at the fracture site during the hematoma formation stage, which provides a framework for forming new bone tissue. In the inflammation stage, the body sends immune cells to the area to remove damaged tissue and debris. The callus formation stage involves the formation of new bone tissue and stabilizing the fracture with the formation of a callus. In the final remodeling stage, the callus is replaced with new bone tissue, restoring the bone’s strength and function.

Possible Complications When A Bone Begins Healing

While the bone healing process is typically straightforward, complications can arise. One common complication is delayed healing which occurs when the bone fails to heal correctly. It can result from various factors, such as inadequate immobilization, poor blood supply, or infection.

Another complication is malunion, which occurs when the bone heals in a misaligned position, leading to deformity and functional impairment. Infection can also occur, further delaying the healing process and increasing the risk of nonunion.

Finally, complex fractures, such as those involving multiple bone fragments or injuries to the surrounding tissues, may be more challenging to heal and require more intensive treatment.

Impact Of Nonunion/Delayed Union Of Bones After A Fracture

Getting emergency care for fractures at Memorial Village Emergency Room is crucial to preventing healing complications. The impact of nonunion or delayed union of bones after a fracture can be significant and can lead to various complications, including-

  • Chronic pain: The pain can be severe and persistent, and it may affect your ability to perform daily activities, work, or engage in physical activities.
  • Deformity: The bones may heal misaligned or malpositioned, leading to a visible disfigurement or functional impairment.
  • Reduced mobility: The affected limb or joint may become stiff, and the range of motion may be limited, leading to difficulties in daily activities.

A nonunion or delayed union can also result in the need for additional surgeries, prolonged recovery time, and higher healthcare costs.

Treating these complications often involves surgery to promote bone healing, such as bone grafting, external fixation, or internal fixation. However, treatment success largely depends on the severity and duration of the complication.
