摘要

Purpose

Facet joint violation (FJV) is an underreported consequence of screw placement in spine surgery, significantly impacting load-bearing capability of the level. Rates of FJV range from 6.3 to 100% due to variability in surgical techniques, navigation methods, and FJV definitions. This study identifies FJV predictors during lumbar fusion in minimally invasive spine surgery (MISS) and open procedures.

Methods

Literature review was performed according to PRISMA guidelines. PubMed, Web of Science and Scopus were searched using keywords “MIS”, “minimally invasive”, “percutaneous”, “endoscopic”, “open”, “conventional”, “traditional”, “lumbar fusion”, “spine fusion”, “FJV”, “facet joint violation”. The quality of studies was evaluated using the Newcastle-Ottawa Scale (NOS). Odds ratio (OR) for dichotomous values and mean difference (MD) for continuous values were calculated. Patients were divided into minimally invasive spine surgery (MISS) and open subgroups.

Results

Seven retrospective studies reporting 1155 patients and 2309 screws were identified, among which 412 violated the facet joint. Body Mass Index (BMI) ≥ 30 predicted FJV, particularly in the MISS subgroup (OR = 3.73, p < 0.0001). Screw placement at L4 level was associated with lower risk (OR = 0.64, p = 0.0003), while L5 level increased the risk of FJV (OR = 1.85, p < 0.0003). Lower pedicle screw angle (PSA) was another FJV predictor (MD= -5.82, p = 0.0002). In the MIS subgroup, 3D navigation decreased the FJV risk (OR = 0.39, p = 0.001).

Conclusion

BMI ≥ 30, screw placement at L5, and a lower PSA increase the risk of FJV during lumbar interbody fusion. Screw placement at L4 and the use of 3D navigation in MISS are associated with a decreased FJV risk. These findings provide valuable insights for optimizing surgical techniques and reducing FJV incidence in lumbar spine instrumentation.
