Summary
Posterior lumbar interbody fusion (PLIF) with threaded fusion cages offers effective lumbar stabilization. This technique demonstrates high fusion rates and excellent patient outcomes, making it a reproducible surgical option.
Area of Science:
- Spine surgery
- Orthopedic surgery
- Neurosurgery
Background:
- Posterior lumbar interbody fusion (PLIF) has gained recognition as a preferred technique for lumbar stabilization.
- Preserving or restoring disc height is crucial for improving intervertebral foramen patency.
Purpose of the Study:
- To evaluate the efficacy and outcomes of posterior lumbar interbody fusion (PLIF) using threaded fusion cages (TFCs).
Main Methods:
- Utilized threaded fusion cages (TFCs) for immediate stabilization and preservation of disc height.
- Employed specialized instrumentation designed for safety and reproducibility.
- Assessed outcomes using the Prolo scale for functional and economic evaluation.
Main Results:
- Achieved a 94% fusion rate at one year post-procedure.
- 83% of cases were rated as good to excellent on the Prolo scale (economic and functional).
- The procedure demonstrated a rapid learning curve and reduced operator dependency.
Conclusions:
- Threaded fusion cages (TFCs) provide immediate stabilization and long-term fusion in PLIF.
- The associated instrumentation enhances safety and reproducibility.
- PLIF with TFCs is an effective and reproducible technique for lumbar stabilization with favorable patient outcomes.
