Posterior lumbar interbody fusion with specialized instruments.
Clinical Orthopaedics and Related Research
|March 1, 1985
Summary
Posterior lumbar interbody fusion (PLIF) using specialized instruments and bone grafts showed good outcomes in 74% of patients. While technically demanding, PLIF effectively stabilizes the spine, though 11% required reoperation for complications.
Area of Science:
- Spine surgery
- Orthopedics
- Neurosurgery
Background:
- Posterior lumbar interbody fusion (PLIF) is a surgical technique for spinal stabilization.
- Previous experience with PLIF in 342 patients informed current practices.
Purpose of the Study:
- To evaluate the outcomes of PLIF performed with specialized instruments and allogeneic bone grafts.
- To assess the safety and efficacy of the PLIF procedure.
Main Methods:
- PLIF was performed on 100 patients between 1979 and 1982.
- Specialized surgical instruments including mortising chisels, cannulated reamers, curettes, and impactors were utilized.
- Allogeneic preserved bone grafts were used for fusion.
Main Results:
- No deaths, infections, or thrombophlebitis were reported postoperatively.
- Excellent or good operative results were achieved in 74% of patients.
- Reoperation was required in 11% of cases for pseudarthrosis, graft extrusion, graft fracture, or hematoma.
Conclusions:
- PLIF is a technically demanding procedure that effectively stabilizes the spine and restores architecture.
- The use of specialized instruments and allogeneic bone grafts in PLIF can yield favorable outcomes.
- Potential complications such as pseudarthrosis and graft extrusion necessitate careful patient selection and surgical technique.
