Fractures and joint injuries can range from simple closed fractures to more complex open or comminuted fractures. The aim of treatment is to save life and restore function. Diagnosis involves history, clinical exam, and imaging like x-rays. Treatment depends on the fracture type but generally involves closed or open reduction and fixation using conservative splinting or surgical methods like plates/screws. Factors like adequate blood supply and immobilization influence healing. Children's fractures have special considerations due to the physis.
