(SPRINGER, 2022-01-01) Bivona, Louis J.; France, John; Daly-Seiler, Conor S.; Burton, Douglas C.; Dolan, Lori A.; Seale, J. Justin; de Kleuver, Marinus; Ferrero, Emmanuelle; Gurd, David P.; Konya, Deniz; Lavelle, William F.; Sarwahi, Vishal; Suratwala, Sanjeev J.; Yilgor, Caglar; Li, Ying
Purpose The Morbidity and Mortality (M\&M) report of the Scoliosis Research Society (SRS) has been collected since 1965 and since 1968 submission of complications has been required of all members. Since 2009, the SRS has collected information on death, blindness, and neurological deficit, with acute infection being added in 2012 and unintentional return to the operating room (OR) being added in 2017. In this report, we use the most recent data submitted to the SRS M\&M database to determine the rate of neurological deficit, blindness, acute infection, unintentional return to the OR, and death, while also comparing this information to previous reports. Methods The SRS M\&M database was queried for all cases from 2013 to 2020. The rates of death, vision loss, neurological deficit, acute infection, and unintentional return to the OR were then calculated and analyzed. The rates were compared to previously published data if available. Differences in complication rates between years were analyzed with Poisson regression with significance set at alpha = 0.05. Results The total number of cases submitted per year varied with a maximum of 49,615 in 2018 and a minimum of 40,464 in 2020. The overall reported complication rate from 2013 to 2020 was 2.86\%. The overall mortality rate ranged from 0.09\% in 2018 to 0.14\% in 2015. The number of patients with visual impairment ranged from 4 to 13 between 2013 and 2015 (no data on visual impairment were collected after 2015). The overall infection rate varied from 0.95 in 2020 to 1.30\% in 2015. When the infection rate was analyzed based on spinal deformity group, the neuromuscular scoliosis group consistently had the highest infection rate ranging from 3.24 to 3.94\%. The overall neurological deficit rate ranged from 0.74 to 0.94\%, with the congenital kyphosis and dysplastic spondylolisthesis groups having the highest rates. The rates of unintentional return to the OR ranged from 1.60 to 1.79\%. Multiple groups showed a statistically significant decreasing trend for infection, return to the operating room, neurologic deficit, and death. Conclusions Neuromuscular scoliosis had the highest infection rate among all spinal deformity groups. Congenital kyphosis and dysplastic spondylolisthesis had the highest rate of neurological deficit postoperatively. This is similar to previously published data. Contrary to previous reports, neuromuscular scoliosis did not have the highest annual death rate. Multiple groups showed a statistically significant decreasing trend in complication rates during the reporting period, with only mortality in degenerative spondylolisthesis significantly trending upwards.
Obeid-Coronal Malalignment Classification Is Age Related and Independently Associated to Personal Reported Outcome Measurement Scores in the Nonfused Spine
(KOREAN SPINAL NEUROSURGERY SOC, 2021-01-01) Kieser, David Christopher; Boissiere, Louis; Bourghli, Anouar; Hayashi, Kazunori; Cawley, Derek; Yilgor, Caglar; Alanay, Ahmet; Acaroglu, Emre; Kleinstueck, Frank; Pizones, Javier; Pellise, Ferran; Perez-Grueso, Francisco Javier Sanchez; Obeid, Ibrahim; Grp, European Spine Study
Objective: To evaluate Obeid-coronal malalignment (O-CM) modifiers according to age, sagittal alignment, and patient-reported outcome measures (PROMs), in the mobile spine. Methods: Retrospective review of a prospective multicenter adult spinal deformity (ASD) database with 1,243 (402 nonoperative, 841 operative) patients with no prior fusion surgery. Patients were included if they were aged over 18 years and were affected by spinal deformity defined by one of: Cobb angle >\_ 20 degrees, pelvic tilt >\_ 25 degrees, sagittal vertical axis >\_ 5 cm, thoracic kyphosis >\_ 60 degrees. Patients were classified according to the O-CM classification and compared to coronally aligned patients. Multivariate analysis was performed on the relationship between PROMs and age, global tilt (GT) and coronal malalignment (CM). Results: Four hundred forty-three patients had CM of more than 2 cm compared to 800 who did not. The distribution of these modifiers was correlated to age. After multivariate analysis, using age and GT as confounding factors, we found that before the age of 50 years, 2A1 patients had worse sex life and greater satisfaction than patients without CM. After 50 years of age, patients with CM (1A1, 1A2) had worse self-image and those with 2A2, 2B had worse self-image, satisfaction, and 36-item Short Form Health Survey physical function. Self-image was the consistent determinant of patients opting for surgery for all ages. Conclusion: CM distribution according to O-CM modifiers is age dependent. A clear correlation between the coronal malalignment and PROMs exists when using the O-CM classification and in the mobile spine, this typically affects self-image and satisfaction. Thus, CM classified according to O-CM modifiers is correlated to PROMs and should be considered in ASD.
Thoracic Scoliosis Screening in Adolescent Patients with Chest Radiographs
(GALENOS YAYINCILIK, 2019-01-01) Eksi, Murat Sakir; Eksi, Emel Ece Ozcan
Aim: School scoliosis screening programs (SSSPs) are valuable and common tools to depict scoliosis prevalence and to take appropriate measures to prevent scoliosis. Prevalence of small angle scoliosis (10-20 degrees) could be underestimated via SSSPs due to inter-rater variability of the physical examination after which possible candidates are sent to radiographic work-up. In this study, we aimed to detect the prevalence of thoracic scoliosis in adolescent patients via analysis of posteroanterior chest radiographs. Methods: Adolescent patients, who had been admitted for reasons other than spine and whose posteroanterior chest radiographs had been obtained, were included in the study. Demographics and chest radiographs were screened through picture archiving and communication system of the hospital. Results: Chest radiographs of 326 (163 female, 163 male) adolescents were evaluated (mean age: 15.54 +/- 2.12 years
