What Causes Flexion Contracture

By March 16, 2023No Comments

Flexion contracture is a medical condition that can occur in various parts of the body, including the knees, elbows, wrists, fingers, and toes. It is characterized by the inability to fully extend a joint due to the tightening of the muscle-tendon unit.

There are several possible causes of flexion contracture:

1. Trauma: Injuries to the muscles, tendons, or ligaments surrounding a joint can lead to flexion contracture. For example, a severe knee injury may cause the quadriceps muscle to become stiff and shorten, resulting in a flexed knee.

2. Neurological conditions: Diseases or injuries that affect the nerves that control muscle function can cause flexion contracture. For example, conditions such as cerebral palsy or stroke can affect muscle tone, leading to contractures.

3. Prolonged immobilization: Keeping a joint in a fixed position for an extended period can cause the muscle-tendon unit to shorten, resulting in contracture. This can occur due to conditions such as joint fractures, burns, or even prolonged bed rest.

4. Inflammatory conditions: Certain inflammatory conditions, such as rheumatoid arthritis, can cause joint inflammation and damage that leads to flexion contracture.

5. Muscular dystrophy: This is a genetic condition that leads to progressive muscle weakness and degeneration. Over time, the muscles may shorten and become stiff, resulting in contractures.

Treatment of flexion contracture varies depending on the cause and severity of the condition. In some cases, stretching and physical therapy may be helpful in reducing contractures. In more severe cases, surgery may be necessary to release the tightened muscle-tendon unit.

It is essential to recognize the signs of flexion contracture early to prevent further deterioration of the affected joint. Seeking medical attention promptly can help to prevent complications and improve overall outcomes.
