(INT SOC ADVANCEMENT SPINE SURGERY-ISASS, 2021-01-01) Pizones, Javier; Moreno-Manzanaro, Lucia; Vila-Casademunt, Alba; Fernandez-Baillo, Nicomedes; Sanchez-Marquez, Jose; Talavera, Gloria; Obeid, Ibrahim; Alanay, Ahmet; Kleinstuck, Frank; Pellise, Ferran; Sanchez Perez-Grueso, Francisco Javier; ESSG
Background: There is scarce information available about adult congenital spine deformity (ACSD) in the literature, especially its impact after the pediatric age. The aim was to define ACSD characteristics and to establish the drivers for surgical intervention. Methods: Cross-sectional study of data collected in an adult deformity multicenter database. Only ACSD patients were included. Demographic and radiographic data, as well as patient-reported outcome measures, were assessed. Conservatively (C) vs surgically (S) treated patients were compared using Student t test, chi(2), and Mann-Whitney U test. Results: Fifty-two patients were included. They were young adults (x = 37.7 years), mostly female (71\%). Among them. 60\% had single hemivertebrae (HV), 35\% had multiple HV, and 5\% had segmentation defects. Also. 75\% had mainly corona' deformity (Cobb 625 degrees +/- 29.6) and 25\% had sagittal deformity. Mean Oswestry Disability Index (ODI) was 29.6\% +/- 17 and mean Scoliosis Research Society 22-item survey (SRS-22) total score was 3.2 +/- 0.8. Of note, mean SRS-22 self-image score was 2.8 +/- 0.9 and 36-item Short Form Health Survey (SF-36) physical function score was 40.9 +/- 11. Thirty patients were treated conservatively (C), whereas 22 patients underwent surgery (S). No differences were found regarding age, type or location of the deformity, comorbidities, or radiographic parameters. Operated patients had worse Core Outcome Measurement Index (COMI) back scores (C: 3.8 +/- 2.4 vs S: 6.7 +/- 2.4
Adult Spinal Deformity Over 70 Years of Age: A 2-Year Follow-Up Study
(INT SOC ADVANCEMENT SPINE SURGERY-ISASS, 2019-01-01) Karabulut, Cem; Ayhan, Selim; Yuksel, Selcen; Nabiyev, Vugar; Vila-Casademunt, Alba; Pellise, Ferran; Alanay, Ahmet; Sanchez Perez-Grueso, Francisco Javier; Kleinstuck, Frank; Obeid, Ibrahim; Acaroglu, Emre; Grp, European Spine Study
Background: Treatment of adult spinal deformity (ASD) in elderly patients remains controversial. The aim of this study was to identify the factors leading to the surgical treatment by comparing the baseline characteristics of operative versus nonoperative patients, to evaluate the safety and efficacy of surgery, and to compare operative and nonoperative management of elderly ASD patients at the end of the 2-year follow-up period. Methods: Retrospective review of a multicenter, prospective ASD database was performed. Patients over 70 years of age with ASD who were scheduled to undergo surgical treatment and who were treated and/or followed without surgical intervention participated in the study. Demographic, clinical, surgical, and radiological characteristics and health-related quality-of-life (HRQOL) (Core Outcome Measures Index {[}COMI], Oswestry Disability Index {[}ODI], Short-Form-36 Mental Component Summary {[}SF-36 MCS], Short-Form-36 Physical Component Summary {[}SF36-PCS], and Scoliosis Research Society-22 {[}SRS-22]) parameters of such group of patients were evaluated pre-and posttreatment. Results: A total 90 patients (females: 71, males: 29
Relative lumbar lordosis and lordosis distribution index: individualized pelvic incidence-based proportional parameters that quantify lumbar lordosis more precisely than the concept of pelvic incidence minus lumbar lordosis
(AMER ASSOC NEUROLOGICAL SURGEONS, 2017-01-01) Yilgor, Caglar; Sogunmez, Nuray; Yavuz, Yasemin; Abul, Kadir; Boissiere, Louis; Haddad, Sleiman; Obeid, Ibrahim; Kleinstuck, Frank; Sanchez Perez-Grueso, Francisco Javier; Acaroglu, Emre; Mannion, Anne F.; Pellise, Ferran; Alanay, Ahmet; Grp, European Spine Study
OBJECTIVE The subtraction of lumbar lordosis (LL) from the pelvic incidence (PI) offers an estimate of the LL required for a given PI value. Relative LL (RLL) and the lordosis distribution index (LDI) are PI-based individualized measures. RLL quantifies the magnitude of lordosis relative to the ideal lordosis as defined by the magnitude of PI. LDI defines the magnitude of lower arc lordosis in proportion to total lordosis. The aim of this study was to compare RLL and PI - LL for their ability to predict postoperative complications and their correlations with health-related quality of life (HRQOL) scores. METHODS Inclusion criteria were >= 4 levels of fusion and >= 2 years of follow-up. Mechanical complications were proximal junctional kyphosis/proximal junctional failure, distal junctional kyphosis/distal junctional failure, rod breakage, and implant-related complications. Correlations between PI - LL, RLL, PI, and HRQOL were analyzed using the Pearson correlation coefficient. Mechanical complication rates in PI - LL, RLL, LDI, RLL, and LDI interpreted together, and RLL subgroups for each PI - LL category were compared using chi-square tests and the exact test. Predictive models for mechanical complications with RLL and PI - LL were analyzed using binomial logistic regressions. RESULTS Two hundred twenty-two patients (168 women, 54 men) were included. The mean age was 52.2 +/- 19.3 years (range 18-84 years). The mean follow-up was 28.8 +/- 8.2 months (range 24-62 months). There was a significant correlation between PI - LL and PI (r = 0.441, p < 0.001), threatening the use of PI -LL to quantify spinopelvic mismatch for different PI values. RLL was not correlated with PI (r = -0.093, p > 0.05)
