Indications for anterior decompression
Indications for decompression during anterior reconstruction includes:
- The presence of a traumatic disc herniation causing neurologic injury (discectomy alone)
- The need to remove a portion or entire vertebral body followed by reconstruction for stability, or for relief of symptomatic neural compression
- Kyphotic angulation with ventral compression.
Corpectomy is performed when the anterior column is severely compromised and/or to remove bone material from the spinal canal. In this procedure diskectomies above and below the fractured vertebra are performed first, allowing visualization of the upper and lower limits of the spinal canal.
