Summary
This study shows that extraforaminal lumbar interbody fusion (ELIF) is a feasible minimally invasive technique for degenerative lumbar disorders, validated by digital simulation and cadaveric studies.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Degenerative lumbar disorders require effective surgical treatments.
- Minimally invasive techniques aim to reduce surgical trauma and improve recovery.
- Extraforaminal lumbar interbody fusion (ELIF) is an emerging technique.
Purpose of the Study:
- To investigate the feasibility of a novel extraforaminal lumbar interbody fusion (ELIF) approach.
- To evaluate ELIF using digital simulation and cadaveric studies.
- To assess ELIF as a minimally invasive technique for degenerative lumbar disorders.
Main Methods:
- Surgical simulation using Mimics software.
- Cadaveric validation of the ELIF procedure and anatomical measurements.
- Documentation of anatomical measures for ELIF approach.
Main Results:
- Digital simulation vividly demonstrated the ELIF procedure.
- Cadaveric study confirmed the feasibility of the ELIF approach.
- ELIF utilizes a lateral access (8-9 cm from midline) with a 9 cm depth, facilitating screw and cage placement.
Conclusions:
- Extraforaminal lumbar interbody fusion (ELIF) is feasible based on simulation and cadaveric findings.
- Further biomechanical studies are necessary.
- Investigate ELIF's potential to preserve posterior tension bands, enhance stability, and expedite recovery.
