Imaging of Postoperative Spine

11

and Rod J. Oskouian

11.1\ Overview

The main categories of spine surgery include stabilization, decompression, disc replacement, as well as percutaneous vertebral augmentation and other minimally invasive procedures (Table 11.1).

Postoperative imaging is generally obtained to evaluate the position of implants, adequacy of decompression, fusion status, and potential complications. The imaging findings of spine surgical procedures, devices and implants, and complications are depicted throughout the chapter.

Table 11.1  Main types of spine surgery

 

 

Technique

Description

Stabilization

 

Fusion (spondylodesis)

Uniting portions of the spine via instrumentation and/or graft materials. A

 

variety of approaches can be implemented (anterior, lateral, posterior, etc.)

 

 

Distraction

Halo, traction, interfacet, or interspinous process devices to provide

 

distractive force to vertebral column

Decompression

 

Laminotomy

Partial removal of the lamina on one side

 

 

Hemilaminectomy

Removal of a single lamina with exposure limited to one side of the

(unilateral laminectomy)

interspinous ligament with decompression of one or both sides of the spinal

 

canal

 

 

Total laminectomy

Removal of the bilateral lamina along with the spinous process

 

 

Laminoplasty

Expansion of the spinal canal while preserving the dorsal laminar arch

Corpectomy

Complete or partial removal of the vertebral body

Vertebrectomy (spondylectomy)

Complete or partial removal of the vertebra

Foraminotomy

Expansion of the neural foramen, usually via resection of part or all of the

 

facet

Facetectomy

Resection of part or all of the facet

Discectomy/microdiscectomy

Removal of herniated disc material

 

 

Miscellaneous

 

 

 

Disc and nucleus pulposus

Dynamic reconstruction of the intervertebral disc with artificial disc or

replacement

nucleus pulposus

Dynamic stabilization

Various devices inserted into the disc space, interspinous space, or facet joints

 

 

Vertebroplasty, kyphoplasty,

Minimally invasive injection of cement or device into vertebrae, or sacrum,

skyphoplasty, Kiva implantation,

with or without balloon expansion

and sacroplasty

 

 

 

Nucleoplasty

Radiofrequency ablation of herniated disc

 

 

Epidural blood patch

Minimally invasive closure of dura for treatment of cerebrospinal fluid leaks
