Object:
Clinical and radiographic results were assessed to determine the clinical outcomes and fusion rate in eight consecutive patients selected for minimally invasive transforaminal lumbar interbody fusion (TLIF) in which a percutaneous pedicle screw system was used unilaterally.
Methods:
Eight patients underwent one-level, minimally invasive TLIF in which a percutaneous pedicle screw system was used only on the side where facets were removed for interbody access. Clinical, economic, functional, and radiographic data were recorded preoperatively and at 6 months postoperatively. The mean 6-month change in the modified Prolo Scale score was 7, and osseous interbody bridging assessed on coronal and sagittal computerized tomography studies was seen in all patients.
Conclusions:
The use of unilateral percutaneous pedicle screw instrumentation for the minimally invasive TLIF procedure provides excellent clinical results and is an option in selected patients.
