Locoregional Parameters: Possible Predictor of Global Sagittal Imballance in Degenerative Spondylolisthesis Patients

Original language description

AIM Global sagittal spine imbalance is of interest in patients with degenerative spondylolysis L4-5.The following study aims at finding the correlation between selected local and regional parameters and the presence of global sagittal imbalance of the spine. The study tries to identify which local and regional findings contribute to development of global sagittal imbalance. MATERIAL AND METHODS The group of 40 consecutive patients planned during last 3 years for open decompression and stabilization for degenerative spondylolisthesis, subgroup of fully ballanced and subgroup, where global sagittal disbalance was measured (according to SVA and SVA / SFD), were defined. In these patient subgroups values of followoving parameters were calculated: degree of shift (measured by Mayerding), angular position in segment L4 / 5, percentage of lordosis L4- S1 to the lumbar lordosis, pelvic incidence and patient age. These values had been statistically compared in patients with and without a global imbalance. All measurements were made on lateral full-body radiographs in standardized position of the patient using the JIVEX digital browser software. RESULTS The presence of global sagittal imbalance correlated with finding of segmental L4-5 kyphosis and the decrease of the value of L4-S1 lordosis and also that of lumbar lordosis. The other paramaters did not reach the degree of statistical significance. CONCLUSION The global sagittal imbalance should be expected in those patients with degenerative L4-5 spondylolisthesis where L4-5 segmental kyphotisation, decrease in the lordosis of two presacral segments and loss of the lumbar lordosis is identified.
