A simple fracture, also known as a closed fracture, occurs when a bone breaks but does not pierce the skin. This type of fracture is typically caused by trauma, such as a fall or a direct blow. The broken bone may be aligned or misaligned, but there is no open wound associated with the injury. Treatment for a simple fracture usually involves immobilization with a cast or splint to allow the bone to heal properly. In some cases, pain relief and physical therapy may be recommended. Healing time varies depending on the location and severity of the fracture, as well as the individual's overall health.
