Final answer:
The signs and symptoms of a closed long bone fracture include swelling, bruising, pain, tenderness, difficulty in moving the limb, and deformity. A complete healing process involves hematoma formation, calli development, and bone remodeling. Prompt and appropriate emergency medical treatment is required for recovery.
Step-by-step explanation:
The signs and symptoms of a single closed long bone fracture include all of the following: swelling and bruising at the site of the fracture, pain and tenderness, difficulty moving the affected limb, and deformity or abnormal shape of the bone. It's important to note that while pain may extend beyond the fracture location due to surrounding muscle or ligament injuries, a full range of motion does not rule out the presence of a fracture. Moreover, while many fractures result in a bruise, this is not always immediate or present at all.
When a bone is fractured, the body initiates a healing process which includes the formation of a hematoma, followed by the development of internal and external calli. Osteoclasts and osteoblasts play essential roles in resorbing dead bone and creating new bone respectively, which eventually leads to the bone remodeling and the completion of the healing process. Understanding these facts about fractures is crucial for proper emergency medical treatment and recovery.
