Abstract
Disc herniation produces a compressive lesion od adjacent spinal nerve root (SNR). Routine electrodiagnostic tests evaluate indirect effects of compression of SNR. Surgical manipulation during herniated disc removal may produce additional, mostly transient SNR malfunction, known as "battered root synrome". Monitoring of SNR function during disc removal is possible by continuous direct detection of compound action potential from the SNR. Potentially harmfull manipulation can be recognised and stopped in time. In H-reflex, direct epidural detection of P1 and P2 waves from the root enables selective evalvation of ventral and dorsal root separately. Initial degree of SNR compressive lesion will be intraoperatively evaluated (presence / absence, amplitude, latency, midpotential interval of P1 and P2 waves.) and later correlated to preoperative clinical signs and symptoms, electrodiagnostic tests (EMG). Prognostic value of H reflex could be determined. Monitoring of SNR function during disc removal will enable recognition of harmful manipulations, resulting in refinement of surgical technique and decreasing perioperative morbidity.
