| Summary: | Post-traumatic osteonecrosis of the vertebra was first described in 1895 by the German surgeon Hermann Kummell. This disease characterized by the development of kyphotic deformity in the spine was identified prior to the emergence of radiography. The most widely accepted hypothetical pathophysiology is avascular osteonecrosis. Affected vertebrae is usually seen in the thoracolumbar region extending from T8 to L2. This disease is seen rare in the lumbosacral region. The primary aims of surgical treatment of Kummell's disease are neural decompression, stabilization and normal sagital balance of the spinal column. It can be treated by anterior reconstriction, posterior stabilisation, kifoplasty ve vertebroplasty. In this report, We review the clinical features and the diagnostic tools of Kummell's disease and also treatment options accompanied by a case report with kummel disease in L5 spine.
