Trans-Endplate Pedicle Pillar System in Unstable Spinal Burst Fractures: Design, Technique, and Mechanical Evaluation
BACKGROUND Short-segment pedicle screw instrumentation (SSPI) is used for unstable burst fractures to correct deformity and stabilize the spine for fusion. However, pedicle screw loosening, pullout, or breakage often occurs due to the large moment applied during spine motion, leading to poor outcomes. The purpose of this study was to test the ability of a newly designed device, the Trans-Endpla...
متن کاملA comparative analysis of the efficacy of short-segment pedicle screw fixation with that of long-segment pedicle screw fixation for unstable thoracolumbar spinal burst fractures
The indications for operative treatment and type of stabilization procedures for the treatment of thoracolumbar burst fracture remain controversial. As surgical reconstruction for the thoracolumbar burst fracture, both long-segment pedicle screw fixation and short-segment pedicle screw fixation including fractured vertebral body have been used widely. The present study evaluated the efficacy of...
متن کاملManagement of unstable thoracolumbar spinal fractures by pedicle screws and rods fixation.
BACKGROUND The thoracolumbar junction is the most common area of injury to the axial skeleton. Forces along the long stiff kyphotic thoracic spine switch abruptly into the mobile lordotic lumbar spine at the thoracolumbar junction. Goals of treatment are to obtain a painless, balanced, stable spine with optimum neurological function and maximum spine mobility. The present prospective study has ...
متن کاملOperative management of unstable thoracolumbar burst fractures.
Operative management of unstable burst vertebral fractures is challenging and debatable. This study of such cases was conducted at the Aga Khan Hospital, Karachi from January 1998 to April 2003. All surgically managed spine injuries were reviewed from case notes and operative records. Clinical outcome was assessed by Hanover spine score and correction of kyphosis was measured for radiological a...
متن کاملPosterior spinal fixation with pedicle screws and rods system in thoracolumbar spinal fractures.
OBJECTIVE To determine the effectiveness of posterior spinal fixation in maintaining the stability of spine and to determine mortality in 6 months after posterior spinal fixation. STUDY DESIGN Quasi experimental study. PLACE AND DURATION OF STUDY Department of Orthopaedics, Jinnah Postgraduate Medical Centre, Karachi and Department of Orthopaedics, Postgraduate Medical Institute, Hayatabad ...
