Why don't you cast a nondisplaced rib fracture?

A nondisplaced rib fracture typically does not require casting because the ribs are surrounded by muscles and have a natural ability to heal without immobilization. Casting can restrict breathing and lung expansion, potentially leading to complications like pneumonia. Instead, treatment usually focuses on pain management and encouraging deep breathing exercises to maintain lung function. Additionally, rib fractures generally heal well with conservative care.
