Possible effects of lumbar stabilization surgery on sagittal alignment, disability and quality of life

Abstract

Background In order to restore the individual's health in lumbar stabilization surgeries, it is aimed to bring the sagittal alignment closer to normal values, to eliminate the findings, and thus to increase the quality of life of the individual by reducing the disability level. The aim of this study is to measure the effects of lumbar region stabilization surgeries performed in our clinic on some angular values in the spine, disability and quality of life. Preoperative (preop) and postoperative (postop) radiographs of 30 individuals over the age of 40 who applied to our clinic with various lumbar region complaints and underwent lumbar stabilization surgery between the years 2020–2022 were taken. Lumbar lordosis, pelvic tilt, sacral slope and pelvic inclination angles were measured from the images obtained. The Visual Analog Scale was used to measure the pain of individuals, the Oswestry Disability Index to measure the disability level, and the Nottingham Health Profile questionnaire to measure the quality of life. Preop and postop data were analyzed with the SPSS 23.0 program and p < 0.05 was considered significant. Results The lumbar lordosis angles of individuals who underwent lumbar stabilization surgery approached normal values and the difference between preop–postop lumbar lordosis angle averages was significant (p < 0.05); It was observed that the harmony between the lumbar lordosis and pelvic inclination angles increased, the pain decreased and the difference between preop–postop pain values was significant (p < 0.05), disability levels decreased and quality of life increased. Conclusions The decrease in the level of disability and the increase in the quality of life seen in individuals who underwent lumbar stabilization surgery were associated with the decrease in pain; The changes in angular values are considered to be clinically significant.
