Optimizing Lordosis Preservation in Monosegmental Lumbar Spondylodesis: Evaluating the Efficacy of a Novel non-invasive Technique Using Intraoperative Hip Hyperextension
Description
This study evaluates a new intraoperative technique for lumbar spondylodesis, using hip hyperextension and an inflatable bladder to maintain lordosis. In 100 patients, significant improvements in Distal Lordosis and Sacral Slope were observed, demonstrating the technique’s efficacy in preserving lordosis during spinal fusion.

Between January 2020 and December 2021, 100 consecutive patients scheduled for monosegmental spondylodesis including L4 and L5 (L3/4 (5), L4/5 (91) or L5/S1 (4), were enrolled. Exclusion criteria were spondylolysis, infection, previous spondylodesis operation, spinal fractures, malignancies, or lumbar scoliosis (Cobb angle > 20°). Descriptive statistics, including mean and standard deviation (±), were calculated for the lumbar lordosis angles in the specified table positions. The Shapiro–Wilk test was used to assess the normality of data distribution to include parametric and/or parametric tests. A p-value of less than 0.05 was considered statistically significant.
