Risk factors of recurrent disc herniation.

C Reith1, G Lausberg

Summary

Recurrent disc herniation is the primary reason for reoperation (62%). Factors like short pain-free intervals and long pre-operative symptoms correlate with longer reoperation times and higher risk scores for disc prolapse recurrence.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Orthopedics

Background:

  • Disc herniation often requires reoperation.
  • Understanding reoperation causes is crucial for patient outcomes.

Purpose of the Study:

  • To analyze the causes of disc herniation reoperations.
  • To identify risk factors for recurrent disc prolapse.

Main Methods:

  • Review of 100 cases undergoing disc herniation reoperation.
  • Analysis of reoperation causes: recurrence, pseudorecurrence, nerve root issues.
  • Evaluation of reoperation timing and pre-operative factors.
  • Development and application of a risk score for prolapse recurrence.

Main Results:

  • Recurrent disc herniation at the same level accounted for 62% of reoperations.
  • Pseudorecurrence (24%) and nerve root involvement (14%) were other causes.
  • 44% of reoperations occurred within two years, 69% within five years.
  • Longer intervals between operations were associated with short post-operative pain-free periods and prolonged pre-operative symptoms.
  • A risk score identified 64% of patients as belonging to a high-risk group for prolapse recurrence.
  • Patients with short reoperation intervals exhibited high-risk scores.

Conclusions:

  • Recurrent disc herniation is the leading cause of reoperation.
  • A validated risk score can identify patients at high risk for recurrence.
  • Timing of reoperation and pre-operative symptom duration are significant factors.
