The expandable lateral interbody cage with integrated fixation (eLLIFp) offers a safe, effective, and cost-saving solution for adjacent segment disease after lumbar fusion. This minimally invasive approach improves outcomes and reduces expenses compared to traditional methods.

Area of Science:

  • Spine surgery
  • Orthopedic surgery
  • Minimally invasive spinal procedures

Background:

  • Adjacent segment disease (ASD) is a complication of posterior lumbar fusion.
  • Traditional treatments for ASD carry risks like nonunion, nerve injury, and vertebral fracture.
  • Minimally invasive lateral lumbar interbody fusion is an alternative management strategy.

Purpose of the Study:

  • To evaluate the clinical and radiographic outcomes of the expandable lateral titanium interbody cage with integrated lateral fixation (eLLIFp) for ASD.
  • To compare the cost-effectiveness of eLLIFp to alternative surgical options for ASD.

Main Methods:

  • A prospective, observational study of 33 patients with ASD above previous posterior lumbar fusions.
  • Patients underwent surgery using eLLIFp devices.

  • Clinical outcomes, radiographic results, and total costs were analyzed.

    • Main Results:

    • Significant improvement in all clinical outcomes was observed.
    • The eLLIFp procedure resulted in improved segmental lordosis and disc height.
    • A 94% interbody fusion rate was achieved at 12 months with low complication rates and lower overall costs compared to alternatives.

    Conclusions:

    • eLLIFp is a minimally invasive, low-morbidity, cost-effective option for treating rostral lumbar ASD.
    • It serves as a robust alternative to traditional posterior construct extension surgery.
    • eLLIFp is a safe and effective treatment for selected patients with adjacent segment disease.
