Study Design: Single-center retrospective study
Objective: To clarify whether an occupancy rate of pedicle screw (ORPS) <80% in an upper instrumented vertebra (UIV) is a risk factor for UIV fracture (UIVF).
Summary of Background data: The ratio of the length of the pedicle screw to the anteroposterior diameter of the vertebral body at the UIV is defined as ORPS. Previous studies showed that the stress on the UIV is most reduced when ORPS is >80%. However, it remains unclear whether these results are clinically valid.
Methods: A total of 297 patients who had undergone adult spinal deformity surgery were included in the study. UIVF incidence was assessed and a logistic regression analysis was conducted to uncover the risk factors for UIVF. The group with an ORPS ≥80% and <80% was defined as the H (n=198) and L (n=99) group, respectively.
Results: The mean age of both groups was 69 years. The average ORPS in the L and H groups was 70% and 85%, respectively. The incidence of UIVF was 30% in group L and 15% in group H (P<0.01). Additionally, the 99 patients in group H were subdivided into two groups, according to whether the screws penetrated the anterior wall of the vertebral body: 68 patients had no penetration (group U), while it was present in 31 patients (group B). A total of 10% and 26% of the patients in the U and B groups, respectively, experienced 1 UIVF (P<0.05). Logistic regression analysis of possible UIVF risk factors revealed an odds ratio of 3.9 for ORPS <80% (P=0.007, 95% confidence interval 1.4-10.5).
Conclusion: To reduce UIVF, screw length should be set with a target ORPS of 80% or higher. If the screw is long enough to penetrate the anterior wall of the vertebral body, the risk of UIVF is greater. |
