Pedicle screw malposition following spinal lumbar injury
Pedicle screws are the main type of instrumentation used in the lumbar spine via the posterior approach. The accuracy of their insertion is always a concern because the malposition of screws is associated with a potential risk of iatrogenic injury of any neurovascular structure they pass. Fortunately, spinal cord and cauda equina injuries are rare. This 18-year-old paraplegic woman presented mo...
متن کاملDesign and performance of spinal fixation pedicle screw system.
Pedicle screw-rod bilateral constructions are extensively used in spinal fixation. In this study, the common cause for failure of bilateral constructions has been determined to be the high stress concentration at the rod-setscrew interface. In order to overcome this problem, a design modification has been made by using a supplementary part (shoe) between rod and setscrew. Performance comparison...
متن کاملPedicle screw surface coatings improve fixation in nonfusion spinal constructs.
STUDY DESIGN Biomechanical and histologic analysis. OBJECTIVE To compare the strength of the bone-screw interface of standard uncoated pedicle screws with screws treated with hydroxyapatite (HA), titanium plasma spray (TPS), and a composite HA-TPS coating. SUMMARY OF BACKGROUND DATA Transpedicular screw fixation has become the gold standard in the treatment of various thoracolumbar spinal c...
متن کاملaccuracy and complications of pedicle screw insertion for lumbar and thoracolumbar fractures
background: the accuracy of pedicle screw placement is essential for lumbar and thoracolumbar spine fracture fixation. purpose: the aim of the present study was to assess the accuracy of the pedicle screw placement with conventional c-arm fuoroscopy-guided in these patients. methods: a retrospective review identified patients who underwent operative management with thoracolumbar instruments at ...
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...
