Kummel disease refers to avascular necrosis of which structure?

Kummel disease is avascular necrosis of the vertebral body. It typically follows a minor spine trauma and presents later as vertebral collapse with back pain, sometimes with an intravertebral vacuum cleft seen on imaging. This vertebral focus distinguishes it from avascular necrosis occurring in other bones such as the femoral head, humeral head, or metatarsal head, which are not described by this condition. Therefore, the vertebral body is the correct site.
