====== En Bloc Spondylectomy ======

===== En Bloc Spondylectomy vs. Posterior Vertebral Column Resection =====

==== Definitions ====

**En Bloc Spondylectomy (EBS):**  
Surgical removal of an entire vertebral segment (vertebral body, pedicles, and posterior elements) in one piece. The primary goal is to achieve oncologic margins in spinal tumors.

**Posterior Vertebral Column Resection (pVCR):**  
Removal of one or more vertebral segments through a posterior-only approach, typically in a piecemeal fashion, to correct severe spinal deformities.

| **Main Goal**                        | Oncologic resection with margins           | Correction of severe deformity                 |
| **Type of Resection**               | One-piece (en bloc)                        | Fragmented (piecemeal)                         |
| **Indications**                     | Primary or metastatic spinal tumors        | Congenital kyphosis, post-traumatic deformity, scoliosis |
| **Surgical Approach**               | Anterior, posterior, or combined (360º)    | Posterior-only                                 |
| **Oncologic Application**           | Yes                                        | No                                             |
| **Deformity Correction**            | Limited                                    | Primary goal                                   |

==== Key Differences ====

  * EBS is aimed at curative treatment of vertebral tumors with wide margins.
  * pVCR is used for severe, rigid spinal deformities requiring vertebral resection and spinal cord decompression.
  * EBS often involves combined approaches, while pVCR is performed solely via a posterior approach.

==== Conclusion ====

Although both involve vertebral resection, **they are not equivalent**.  
Each serves a **distinct purpose** with different surgical techniques and goals.
