Ankylosis

Ankylosis is the abnormal stiffness or fusion of a joint. As a result, the affected joint loses part or all of its normal movement.

In some cases, ankylosis develops gradually over time. However, it may also occur after injury, inflammation, surgery, or disease.

The condition can affect any joint in the body. Nevertheless, it is commonly seen in the spine, hip, knee, and shoulder.

What Causes Ankylosis?

Several conditions can lead to ankylosis.

Common causes include:

  • Ankylosing spondylitis
  • Severe arthritis
  • Joint infection
  • Trauma
  • Prolonged immobilization

Over time, these conditions may cause the joint surfaces to become rigid. Consequently, normal movement becomes difficult.

Why is Ankylosis Important?

Ankylosis can significantly affect daily activities.

For example, a person with knee ankylosis may have difficulty walking. Similarly, shoulder ankylosis can make dressing and grooming challenging.

Therefore, early identification and treatment are important.

Ankylosis in Physiotherapy

Physiotherapists assess ankylosis by examining joint movement, pain, and functional limitations.

Treatment may include:

  • Range of motion exercises
  • Stretching exercises
  • Strengthening exercises
  • Functional training
  • Patient education

Although complete joint fusion cannot always be reversed, physiotherapy can improve function and maintain mobility in surrounding joints.

Everyday Example

A person with severe arthritis may gradually lose the ability to fully bend or straighten the knee. This loss of movement may eventually lead to ankylosis.

Clinical Pearl

Fibrous ankylosis allows a small amount of movement. In contrast, bony ankylosis results in complete joint fusion and almost no movement.

Frequently Asked Questions

What is ankylosis?

Ankylosis is the abnormal stiffness or fusion of a joint that restricts normal movement.

Can physiotherapy treat ankylosis?

Physiotherapy can help improve function, maintain mobility, and reduce disability associated with ankylosis.
