Study of Chance Type Fracture

Abstract

We have had experience in treating 18 cases of Chance type fractures. The dominant feature of this fracture is a horizontal fracture involving the posterior element with little or no compression of the vertebral body. In our cases, 4 cases had bony fragments retropulsed from posterior wall. These may be classified to burst fracture. Two cases had rotation and displacement of the vertebral body. These may be classified to fracture dislocation. Surgical treatment with transpedicular fixation was done in 9 cases. For cases with burst fracture, combined anterior decompression and fusion was done.
