Computer tomography assessment of pedicle screw insertion in percutaneous posterior transpedicular stabilization

Percutaneous Transpedicular Interbody Fusion Technique in Percutaneous Pedicle Screw Stabilization for Pseudoarthrosis Following Pyogenic Spondylitis.

This report introduces a percutaneous transpedicular interbody fusion (PTPIF) technique in posterior stabilization using percutaneous pedicle screws (PPSs). An 81-year-old man presented with pseudoarthrosis following pyogenic spondylitis 15 months before. Although no relapse of infection was found, he complained of obstinate low back pain and mild neurological symptoms. Radiological evaluations...

Percutaneous Transpedicular Screw Insertion Technique ( Sextant )

Boucher was the first to use screws that crossed through the strongest point of attachment of the facet joint into the pedicle and the body of the vertebra below. He declared a pseudorthrosis rate of 14% to 17% including multilevel fusions (1). The use of pedicle screw–assisted spinal stabilization has become increasingly popular worldwide. Pedicle screw systems engage all three columns of the ...

Low back pain is described as a deep pain surrounding the waist in a “belt style,” frequently seen in the midline, but which may spread to the hips and upper thighs. In recent years, degenerative disc disease has been observed as the most important result of low back pain. Tearing of the disc capsule, including nerve root irritation from the chemical substances that are expelled (chemical nocic...

Posterior Percutaneous Transpedicular Lumbar Dynamic Stabilization

Three column stabilization through posterior approach alone: transpedicular placement of distractable cage with transpedicular screw fixation.

The combination of anterior and posterior instrumentation provides the most stable repair for burst fractures of the thoracolumbar spine. However, the use of both approaches on a trauma patient may increase morbidity. Stabilization of three columns through only one approach can provide an effective outcome. We treated eight patients with burst fracture involving the thoracic or lumbar vertebrae...
