Early Postoperative Iatrogenic Neuropraxia After Lumbar Disc Herniation Surgery: Analysis of 87 Cases

-BACKGROUND: Postoperative early neuropraxia after lumbar disc herniation surgery is common. The emergence of new paresthesia findings with increased sensory and motor deficits in the postoperative period suggests iatro-genic neuropraxia. This study aimed to discuss the causes and prognosis of iatrogenic neuropraxia detected in the early postoperative period in patients who have been operated on for lumbar disc herniation.-METHODS: Cases with postoperative iatrogenic neuro-praxia were determined retrospectively. Deficits were evaluated at intervals of 0-2 hours, 2-12 hours, 12-24 hours, and 24-48 hours. The cases were evaluated in 2 groups as those who underwent aggressive discectomy and simple discectomy. In addition, the treatment results were compared between the 2 groups as the cases that were treated and not treated with methylprednisolone.-RESULTS: The iatrogenic neuropraxia rate was signifi-cantly higher in patients who underwent aggressive dis-cectomy. Although it was observed that paresthesia findings improved more rapidly in cases treated with methylprednisolone, no difference was found between the 2 groups in terms of its effects on the motor deficit.-CONCLUSIONS: Iatrogenic neuropraxia is a finding whose cause cannot be determined by quantitative criteria. It is common in patients who underwent aggressive dis-cectomy. Methylprednisolone treatment is effective in recovering the paresthesia finding faster and may show that the radicular injury is in the neuropraxia stage in the early period.
