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 کاملIntraoperative biomechanics of lumbar pedicle screw loosening following successful arthrodesis.
Pedicle screw loosening has been implicated in recurrent back pain after lumbar spinal fusion, but the degree of loosening has not been systematically quantified in patients. Instrumentation removal is an option for patients with successful arthrodesis, but remains controversial. Here, we quantified pedicle screw loosening by measuring screw insertion and/or removal torque at high statistical p...
متن کاملManagement of lumbar artery injury related to pedicle screw insertion.
We report on 2 patients who experienced injury to one of their lumbar arteries related to pedicle screw misplacement. In this report, the lumbar pedicle screw holes were made laterally with resultant injury to the lumbar artery. During surgery, arterial bleeding was controlled with pressure and gauze; however, the patients experienced vital shock after surgery. Vital shock ensued and they were ...
متن کاملCorrelation between low triggered electromyographic thresholds and lumbar pedicle screw malposition: analysis of 4857 screws.
STUDY DESIGN A retrospective analysis of 1078 spinal surgical procedures with lumbar pedicle screw placement at a single institution. OBJECTIVE Based on previously established normative values, triggered electromyographic stimulation (TrgEMG) was re-examined to evaluate its efficacy in determining screw malposition. SUMMARY OF BACKGROUND DATA Threshold values for confirmation of intraosseou...
متن کاملCerebral infarction due to malposition of cervical pedicle screw
RATIONALE Malposition of cervical pedicle screw (CPS) has a risk of vertebral artery (VA) injury which sometimes may cause unexpected and catastrophic outcome. A rare case of delayed onset of cerebral infarction caused by malposition of CPS was reported. PATIENT CONCERNS A 23-year-old man who underwent a posterior cervical reduction and fusion of C4-5 using CPS fixation and allograft for cerv...
