Thoracic and lumbar fractures: Posterior long segment fixation

Based on preoperative planning, the amount of lamina to be removed to achieve enough decompression can be determined beforehand.

A laminectomy is performed to provide full exposure of the tumor, and at least half a level above and below that in order to expose normal tissue planes.

Dissection should start above and below the level of the tumor and then continue into the level affected by the tumor, since the tumor may obscure normal tissue planes.
