Objectiveto evaluate spinopelvic balance using the pelvic incidence, sacral slope and pelvic tilt among patients with lumbar disk hernias who underwent surgical treatment.Methodsthirty patients at the spinal services of Hospital Santa Casa de Misericórdia de Vitória and Hospital Vila Velha were evaluated by measuring their spinopelvic balance from the angles of pelvic tilt, sacral slope and pelvic incidence, with their respective means, on simple lateral-view lumbopelvic radiographs that needed to encompass the lumbar spine, sacrum and proximal third of the femur.Resultsthe spinopelvic balance measurements obtained from the mean angles of the population studied, for pelvic incidence, sacral slope and pelvic tilt, were 45°, 36.9° and 8.1°, respectively. The confidence interval for the mean pelvic incidence was from 41.9 to 48.1 (95% CI), thus including a reference value that characterized it as low, for an asymptomatic population, thus confirming that the sample was extracted from a population with this characteristic.Conclusionamong these patients with lumbar disk hernias who underwent surgical treatment, the average spinopelvic balance was found to have pelvic incidence lower than what has been reported in the literature for an asymptomatic population.
Objective:We compared gains in range of motion in patients who underwent manipulation within 12 weeks of total knee arthroplasty (TKA) and after this period. We also evaluated maintenance of the arc obtained from knee manipulation in late follow-up, along with factors associated with poorer outcomes. Method:The study was divided into two groups according to the time after TKA; the surgeries took place between January 2008 and December 2014. Results:When comparing the range of motion between early and late manipulations, the group that underwent manipulation within 12 weeks of the TKA exhibited better outcomes, but these were not statistically significant. We observed that 14.3% of cases retained the same range attained at the time of manipulation. In late evaluation after manipulation, 47.7% of the sample had a range of less than 90 degrees. The significant risk factors for recurrence of knee stiffness in the long term are poor range of motion before TKA and before manipulation, female sex, and secondary arthritis. Conclusion:Women previously diagnosed with secondary osteoarthritis and poor range of motion before TKA or manipulation are at higher risk for late stiffness. Level of Evidence III, Retrospective Comparative Study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations –citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
