Summary

Posterolateral cage fusion is a viable option for recurrent lumbar disc herniation (RLDH) after prior surgery. This method demonstrated high fusion success and satisfactory clinical outcomes in 14 RLDH patients.

Area of Science:

  • Spine surgery
  • Orthopedic surgery
  • Neurosurgery

Background:

  • Recurrent lumbar disc herniation (RLDH) often requires revision surgery.
  • Posterior interbody fusion after repeated discectomy is challenging due to surgical scarring.
  • Alternative fusion techniques are needed for RLDH when fusion is indicated.

Purpose of the Study:

  • To evaluate the efficacy of posterolateral placement of a single cylindrical threaded cage for interbody fusion in RLDH patients.
  • To assess the safety and clinical outcomes of this specific fusion technique.

Main Methods:

  • A prospective study of 14 RLDH patients who failed conservative treatment.
  • Posterolateral decompression and single cage insertion through the virgin side.
  • Follow-up assessment of fusion success and clinical results.

Main Results:

  • Successful interbody fusion was achieved in 12 out of 14 patients (85.8%).
  • 13 patients (92.9%) reported satisfactory clinical outcomes (6 excellent, 7 good).
  • No dural tears or neurological deficits were observed; minor complications included superficial wound infections and a UTI.

Conclusions:

  • Posterolateral single cage fusion is an effective and safe option for RLDH when interbody fusion is necessary.
  • This technique offers a viable alternative to traditional posterior dual cage insertion, especially in previously operated lumbar spines.
  • High fusion rates and excellent clinical results support its use in selected RLDH cases.
