Accuracy of t-EMG stimulation of the middle pedicle track to prevent radiculopathies as a result of misplaced lumbar screws

Accuracy of t-EMG stimulation of the middle pedicle track to prevent radiculopathies as a result of misplaced lumbar screws

•Systematic stimulation prevent the development of postoperative lumbar radiculopathy.•Stimulation of the cortical walls at the middle lumbar pedicle track shows more accuracy in detecting pedicle breaches.•t-EMG thresholds >9 mA in the middle of the pedicle track prevent medial-caudal malpositio...
