Introduction:

spinal deformity in adults has become a pathology whose frequency is increasing due to the tendency towards a longer life in the population, as well as to maintain the level of activity of the same.

Objective:

to describe the variability of spinopelvic parameters in patients with chronic-degenerative lumbar pathology with surgical management.

Material and methods:

observational, descriptive, retrospective and longitudinal study of patients with spondyloarthrosis and/or degenerative lumbar spondylolisthesis undergoing orthopedic surgery. The patients were divided into two groups: instrumentation + fusion (IF), and without instrumentation + release (LSI). pelvic incidence (PI), sacral slope (SS), lumbar lordosis (LL), pelvic tilt (PT) and pelvic incidence minus lumbar lordosis (PI−LL) were measured on the baseline radiograph, at one and six months postoperatively. Statistical analysis was performed with Student’s t-test. Statistically significant value was p < 0.005.

Results:

sample 96 patients. At six months follow-up (A versus B), PI: 52.0 ± 10.1 versus 52.2 ± 14.7 (p = 0.932); SS: 34.1 ± 8.3 versus 32.7 ± 11.0 (p = 0.533); LL: 49.4 ± 13.5 versus 49.0 ± 13.2 (p = 0.889); PT: 17.89 ± 7.6 versus 9.4 ± 8.5 (p = 0.402); PI−LL: 2.58 ± 12.4 versus 3.26 ± 13.84 (p = 0.833).

Conclusions:

changes in spinopelvic parameters were observed in both groups, but were greater in the non-instrumented release group, but were not statistically significant.
