OBJECTIVE To describe the demography, types of injuries and their management in all non-disaster spinal injury patients admitted to the Spine Unit of a tertiary care hospital in Pakistan from 2001-2008. STUDY DESIGN Case series. PLACE AND DURATION OF STUDY Spine Unit, Orthopaedic Department, Combined Military Hospital, Rawalpindi, from April 2001 to December 2008. METHODOLOGY Data of all ...

OBJECTIVE The purpose of this study was to evaluate the efficacy of implant removal of percutaneous short segment fixation after vertebral fracture consolidation in terms of motion preservation. METHODS Between May 2007 and January 2011, 44 patients underwent percutaneous short segment screw fixation due to a thoracolumbar burst fracture. Sixteen of these patients, who underwent implant remov...

STUDY DESIGN An experimental biomechanical study. PURPOSE This study aims to investigate the behavior of a lamina injury in lumbar burst fractures during reduction maneuvers. OVERVIEW OF LITERATURE Lumbar burst fractures are frequently accompanied by a lamina fracture. Many researchers concluded that any reduction maneuver will close the fractured lamina edges and possibly crush the entrapp...

Study Design Case report. Objective The objective of this study was to report a case of an unstable C1 burst fracture in the setting of a vertebral artery anomaly at the craniovertebral junction. Methods A 55-year-old man was admitted to the hospital with severe neck pain after falling approximately 15 feet and landing on his head. Computed tomography scan of the cervical spine revealed an unst...

BACKGROUND The "gold standard" for instrumentation of unstable thoracolumbar fracture-dislocations is pedicle screw and rod fixation. Although traditional treatment supports long-segment posterior fixation (LSPF), more recent studies show short-segment posterior fixation (SSPF) may be effective, but incur higher failure rates. Here, we evaluated the effectiveness of SSPF in the management of un...

BACKGROUND Burst fracture is a common thoracolumbar injury that is treated using posterior pedicle instrumentation and fusion combined with transpedicular intracorporeal grafting after reduction. In this study, we compared the outcome of these two techniques by using radiologic imaging and functional outcome. METHODS Sixty-one patients with acute thoracolumbar burst fracture were operated wit...

To investigate wall-thinning impact on axial load resistance of Zircaloy-4 cladding rods after a LOCA transient, tensile samples have been machined as-received tubes with reduced thicknesses between 370 and 580 ?m. After high temperature oxidation under steam at 1200 °C measured ECR ranging from 10 to 18% water quenching, were axially loaded until fracture. These tests modeled using fracture me...

PURPOSE Previous studies have proved that vascular endothelial growth factor (VEGF) has a dual role in the promotion of new bone formation and blood vessel repair during fracture healing. However, how to introduce VEGF to a fracture site safely and effectively is still a challenge. This study aimed to prepare a VEGF-loaded nanographene coated internal fixation screw and to evaluate its effects ...
