Neural decompression in challenging cases: advantages and disadvantages

Area of Science:

• Spinal surgery
• Orthopedics
• Neurosurgery

Background:

• Degenerative disc disease is a common cause of low back pain.
• Minimally invasive surgical techniques are increasingly utilized for spinal conditions.
• Extreme lateral interbody fusion (LLIF) offers indirect neural decompression via disc space distraction and cage placement.

Purpose of the Study:

• To review the potentials and limitations of LLIF for lumbar degenerative disc disease.
• To provide a comprehensive overview of current literature on LLIF.
• To aid clinical decision-making regarding LLIF application.

Main Methods:

• A literature search was conducted using PubMed.
• Inclusion criteria focused on English-language articles.
• The review synthesizes existing published data on LLIF outcomes.

Main Results:

• LLIF is demonstrated as an effective method for decompressing foraminal and central canal stenosis.
• Current literature indicates less consistent outcomes for LLIF in treating lateral recess stenosis.
• The technique achieves neural decompression by indirectly widening the disc space with an interbody cage.

Conclusions:

• LLIF is a valuable tool for specific types of lumbar spinal stenosis.
• Further research may be needed to clarify LLIF's efficacy in lateral recess stenosis.
• This review aims to enhance informed patient selection and surgical planning for LLIF.
