Evaluate the efficacy of pedicle screw and plate instrumentation in facilitating lumbar and lumbosacral autogenous bone graft fusion in adult degenerative spondylolisthesis.
Enrolled 18 adult patients with grade I or II degenerative spondylolisthesis across three clinical sites.
Performed autogenous bone graft fusion across three levels or fewer using pedicle screw and plate fixation, assessing outcomes after 2 years.
Statistically compared fusion rates against historical control cohorts fused without pedicle screw instrumentation.
Achieved a 2-year fusion rate of 89% in patients receiving pedicle screw and plate instrumentation with autogenous bone graft.
Demonstrated that patients treated with pedicle screw instrumentation were >3 times more likely to fuse than comparable patients treated without fixation.

Implication

Multicenter study reveals high fusion rates with pedicle screw fixation in degenerative spondylolisthesis, suggesting substantial benefits over non-instrumented bone grafting.
