Background:

Degenerative lumbar spondylolisthesis can cause severe sciatica due to L4 nerve root compression.
Neural foramina stenosis is a common cause of nerve root impingement in the lumbar spine.

Purpose of the Study:

To describe and evaluate the CT-guided percutaneous posterior interbody fusion (PIF) technique.
To assess the efficacy of CT-guided PIF in treating degenerative lumbar L4-L5 spondylolisthesis with severe sciatica.

Main Methods:

The study details the specialized tools and procedure for CT-guided percutaneous PIF.
The technique involves pedicle screw fixation and distraction for spinal fusion.
Surgical time was recorded, and CT scan reconstructions were used for foraminal assessment.

Main Results:

The CT-guided PIF procedure was straightforward to perform, with a total surgical time of 90 minutes.
CT scan reconstructions showed significant widening of the neural foramina after PIF.
The patient experienced complete resolution of left leg pain within two weeks, with sustained pain relief at three months.

Conclusions:

CT-guided percutaneous PIF is a feasible and effective minimally invasive surgical option.
This technique successfully decompress L4 nerve roots and alleviates sciatica symptoms.
This represents a novel approach, with no prior literature documenting CT-guided PIF procedures.
