What is the main use of casting in medical treatment?

The primary purpose of casting in medical treatment is to provide complete immobilization of limbs. This immobilization is crucial for promoting proper healing of fractures and broken bones by preventing movement in the affected area. When a limb is casted, it helps to stabilize the bone in the correct alignment, reducing the risk of complications such as malunion or nonunion of the fracture.

Casting plays a vital role in the healing process by creating an environment that allows the bone to heal naturally while minimizing discomfort for the patient. The rigidity of the cast restricts mobility, which is necessary for bones to knit back together correctly. This method is widely used in orthopedic treatment, underscoring its importance in ensuring successful recovery from skeletal injuries.
