Vertebral Column: Regions and Curvature01:16

Vertebral Column: Regions and Curvature

The vertebral column or spine is a flexible column that supports the head, neck, and body and  allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...
General Structure of a Vertebra01:30

General Structure of a Vertebra

A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous column.

Area of Science:

  • Orthopedic Surgery
  • Spinal Deformity Correction
  • Vertebral Column Resection

Background:

  • Posterior vertebral column resection (PVCR) is a surgical technique for addressing various spinal deformities.
  • Experience with PVCR in a diverse patient cohort is presented.

Purpose of the Study:

  • To evaluate the efficacy of PVCR in correcting severe spinal deformities.
  • To present surgical outcomes and complications associated with PVCR.

Main Methods:

  • Retrospective review of 37 patients undergoing PVCR between 2015 and 2018.
  • Analysis of demographic data, operative details, blood loss, and neurological status.
  • Preoperative and postoperative spinal curvature measurements using X-ray.

Main Results:

  • PVCR was performed for congenital, tumor, posttraumatic, revision, and infectious spinal deformities.
  • Significant reduction in mean kyphosis angle from 67.65° to 7.42° in advanced deformities (P < 0.001).
  • Overall mean curvature decreased from 55.1° to 3.5° (P < 0.001).

Conclusions:

  • PVCR is an effective surgical option for correcting severe spinal deformities.
  • The procedure demonstrates significant efficacy across various patient populations and etiologies.
  • PVCR can be safely applied to correct substantial spinal curvature.
