Why do you have to wear a cast on broke leg?

A cast provides several important functions in the healing process of a broken leg

1. Immobilization: One of the primary reasons for wearing a cast on a broken leg is to immobilize the affected area. By keeping the bone fragments stable and preventing movement, the cast allows proper healing and prevents complications such as misalignment or improper bone knitting.

2. Protection: A cast provides a protective covering over the injured area, safeguarding it from external impact or injury during the delicate healing process. It shields the sensitive tissues and bone fragments, reducing the risk of further damage or complications.

3. Support: A cast provides support to the injured leg, preventing unnecessary movement or bending that could disrupt the healing bones. It helps bear weight and distribute pressure evenly, reducing strain on the injured area.

4. Alignment: In case of more complex fractures, where there is a need to manipulate or adjust the bone fragments into the correct position, a cast helps maintain the desired alignment. This ensures that the bone heals in the anatomically correct position.

5. Edema control: Some casts are designed to apply gentle compression, which can assist in controlling edema or swelling in the injured leg. By creating a controlled environment, the cast aids in the reduction of swelling and promotes proper circulation.

6. Comfort and pain management: A cast also offers a degree of comfort by securing the injured area and preventing excessive movements that could cause pain. By immobilizing the leg, it reduces discomfort and alleviates the severity of pain, making it easier for individuals to manage their symptoms during the healing process.
