Background: Does posterior cervical herniectomy impact on symptoms related to cervical paramedian/lateral soft disc herniation?
Methods: In a patient series over 15 years operated for single level paramedian/lateral soft disc herniation with posterior cervical approach, perceived radicular and cervical pre- and postoperative symptoms were reconstructed and analyzed.
Results: Out of 105 patients with these characteristics 75 could be recruited for long-term follow-up. Preoperative symptoms included: radicular motor deficit (81.3%); radicular pain (93.3%); radicular sensory deficit (84%); cervical pain (80%) and disturbance of cervical motility (49.3%). Postoperatively radicular motor score improved in all patients (score 5 in 92% and 4 in 8%); sensory disturbance improved in all and radicular pain disappeared in 90% and improved in the others. Cervical pain disappeared in 78% and improved in other 22%, two had new onset moderate cervical pain.
Conclusions: This series confirms safety and efficacy of the posterior approach in relieving motor and sensory symptoms in patients with symptomatic single level, lateral soft disc herniation.
