Background: Trans-pedicular screw placements have been an increasingly popular procedure in many neurosurgery and orthopedic departments. Any mistake at performing the technique could be followed by irreversible neurological deficit and damage of Para spinal vital structures as well as less stability for future fusion. Objectives: In this study we tried to show the benefits and capabilities of ...

Background: The purpose of this prospective study was to determine the accuracy of pedicular screw insertion withoutthe use of fluoroscopy.Methods: This study was conducted on patients with spinal diseases in need of pedicular screw fixation and fusion.The included patients suffered from such conditions as vertebral fracture, spinal stenosis, kyphosis, tumor, and pelvicf...

OBJECTIVE Many lumbosacral fixation techniques have been described to offer a more screw-bone purchase. The forward anatomical fixation parallel to the endplate is still the most preferred method. Literature revealed little knowledge regarding the mechanical stability of lumbosacral trans-endplate fixation compared to the traditional trans-pedicular screw fixation method. The aim of this study ...

BACKGROUND The objective of the study was to improve the accuracy of computer-assisted pedicle screw installation in the spine. This study evaluates the accuracy of computer-assisted pedicle screw placement with separate spinal reference clamp placement and registration on each instrumented vertebra for thoracolumbar spine fractures. METHODS Postoperative radiographs and CT scans assessed the...

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 ...

background & aims: thuracolumbar unstable fractures (t, l.u.f) are common after spine truma. posterior pedicular fixation is a technique that is use for fixation of these fractures. this study evaluates the accuracy of pedicular screw placement in t, luf with the assistance of plain radiography in operation rooms. materials & methods: this study is a case-control and analytical study. 35 patien...

BACKGROUND Treatment of unstable upper and middle thoracic spine fractures remains controversial. There is no consensus regarding optimal treatment. OBJECTIVES In this study, we evaluated the efficacy of pedicular screw in the management of middle thoracic spine fractures to correct kyphosis and anterolisthesis and improve neurologic condition of patients. PATIENTS AND METHODS Twenty-five p...
