Abstract
BACKGROUND: There is currently no mandatory set of preoperative examinations for patients undergoing elective lumbar spine surgery for degenerative disorders, making it difficult to account for critical predictors and achieve predictable clinical and radiological outcomes.
AIM: The work aimed to define the scope of preoperative examinations in patients scheduled for decompression and stabilization surgery for degenerative lumbar spine disease.
METHODS: A retrospective cohort analysis was performed to identify predictors of successful outcomes following single-level decompression and stabilization. Based on the identified predictors and their threshold values, a set of essential preoperative examinations for decompression and stabilization surgery planning was developed. The effectiveness of the predictive model and the feasibility of the proposed set of preoperative examinations were assessed in a prospective patient cohort.
RESULTS: Multivariate analysis identified the following as significant predictors of treatment success: preoperative ODI score, preoperative HADS score, DN4 score, presence of interbody fusion, postoperative lower lumbar lordosis angle, bone mineral density in HU, and postoperative segmental angle. The threshold value for lower lumbar lordosis (Low LL, L4–S1) was 26° (sensitivity, 71.7%; specificity, 91.3%); the segmental angle (SL) threshold was 7° (sensitivity, 87.9%; specificity, 70.6%). The proposed set of essential preoperative examinations for single-level decompression and stabilization surgery planning includes clinical scales (ODI, HADS, DN4), standing spinal radiographs, and lumbar CT and MRI. This set of essential preoperative examinations resulted in a 9.3% increase in clinical success rate (from 74.8% to 84.1%).
CONCLUSION: The set of essential preoperative examinations includes three questionnaires (ODI, HADS, and DN4) and three imaging modalities (standing radiographs, lumbar CT, and lumbar MRI), all of which are typically available at specialized spinal surgery centers. This set is recommended for routine use by spine surgeons, given its role in achieving predictable success following single-level decompression and stabilization surgery of the lumbar spine.
