CT-Guided Posterior Lumbar Interbody Fusion and Distraction. A Case Report.
We performed CT-guided posterior interbody fusion (PIF) with pedicle screw fixation and distraction to treat degenerative lumbar L4-L5 spondylolisthesis with severe left sciatica. The patient was suffering from L4 nerve root compression related to neural foramina stenosis. The dedicated tools to perform a CT-guided percutaneous PIF technique are described. The procedure was easy to apply with a total surgical time of 90 minutes. The neural foramina were investigated by CT scan reconstruction on sagittal plane demonstrating marked widening after PIF application. The left leg pain completely disappeared in two weeks and the patient remained painless at the three month follow-up control. To our knowledge, there are no other papers on CT-guided PIF procedure in the literature.
