Scoliosis in osteogenesis imperfecta: identifying the genetic and non-genetic factors affecting severity and progression from longitudinal data of 290 patients

BackgroundScoliosis is widely prevalent among osteogenesis imperfecta (OI) patients, and is progressive with age. However, factors affecting scoliosis in OI are not well known.MethodsWe retrospectively retrieved longitudinal radiographic and clinical records of consecutive OI patients seeking treatments at our hospital from 2014 to 2022, graded their pre-operative spinal conditions into four outcome groups, estimated their progression rates, and descriptively and inferentially analyzed the genetic and non-genetic factors that may affect the outcomes and progression rates.ResultsIn all, 290 OI patients met the inclusion criteria, where 221 had genetic records. Of these 221, about 2/3 had mutations in COL1A1 or COL1A2, followed by mutations in WNT1 (9.0%), IFITM5 (9.0%) and other OI risk genes. With an average age of 12.0 years (interquartile range [IQR] 6.9–16.1), 70.7% of the cohort had scoliosis (Cobb angle > 10°), including 106 (36.5%) mild (10°–25°), 40 (13.8%) moderate (25°–50°), and 59 (20.3%) severe (> 50°) scoliosis patients. Patients with either COL1A1 and COL1A2 were strongly biased toward having mild or no scoliosis, whereas patients with mutations in IFITM5, WNT1 and other recessive genes were more evenly distributed among the four outcome grades. Lower-limb discrepancy, bone mineral density (BMD) and age of first drug used were all significantly correlated with severity outcomes. Using multivariate logistic regression, we estimated that each year older adds an odds ratio of 1.13 (95% confidence interval [CI] 1.07–1.2) in progression into advanced stages of scoliosis. We estimated a cohort-wide progression rate of 2.7 degrees per year (95% CI 2.4–3.0). Early-onset patients experienced fast progressions during both infantile and adolescent stages. Twenty-five of the 59 (42.8%) patients with severe scoliosis underwent spinal surgeries, enjoying an average Cobb angle reduction of 33° (IQR 23–40) postoperatively.ConclusionThe severity and progression of scoliosis in osteogenesis imperfecta were affected by genetic factors including genotypes and mutation types, and non-genetic factors including age and BMD. As compared with COL1A1, mutations in COL1A2 were less damaging while those on IFITM5 and other recessive genes conferred damaging effects. Progression rates were the fastest in the adolescent adult age-group.

Pediatric Sleep Questionnaire for Sleep Apnea in Newly Diagnosed Adolescent Idiopathic Scoliosis Patients.

Close association has been established between obstructive sleep apnea (OSA) and adolescent idiopathic scoliosis (AIS), with PSQ being employed as a screening method for OSA. A cross-sectional study was conducted among patients aged from 10 to 16 years who presented to a scoliosis outpatient clinic. Patient demographics, radiological assessments, and PSQ scores were gathered. A total of 299 patients were included in the study, with 28.7% males and 71.2% females. The average Cobb angle was 6.20°. PSQ scores revealed a prevalence of 33.4% for significant obstructive sleep apnea. Patients diagnosed with AIS exhibited a prevalence of 32.9% with positive PSQ results. Among those undergoing adenoid and/or tonsil surgery, 27% had positive PSQ scores. Factors such as genetics, abnormal biomechanical forces, environmental factors including melatonin, and intermittent hypoxia were explored for their potential contribution to AIS etiology. The aim of the study is to underscore the importance of early detection and intervention in OSA cases and highlights the effectiveness of the PSQ, as a screening tool in identifying sleep disorders. The findings underscore the complex relationship between OSA and AIS, and moreover any spinal curvature is in relation with OSA.

Determining the factors associated with a prolonged length of stay for adolescent idiopathic scoliosis patients undergoing posterior spinal instrumentation and fusion in a single-payer health care system: are these factors different than those in the United States?

Rapid recovery pathways (RRP) for adolescent idiopathic scoliosis patients undergoing posterior spinal instrumentation and fusion (PSIF) have been shown to be successful in reducing hospital length of stay (LOS). Although the majority of patients are discharged within 3 days, some patients require longer hospital admission. Previous studies in the United States have identified predictors of prolonged LOS for this patient population. The goal of this project was to determine if these predictors are the same for Canadian scoliosis patients and to identify those features which are different under this single-payer system. A RRP for scoliosis surgery was implemented in March 2015 at a single, tertiary referral children's hospital in Canada. Previously identified features, along with numerous other patient factors, were collected. Spearman correlations were used to determine the factors most associated with hospital LOS and those factors were used in a multivariable regression model. A total of 161 patients were included in the analysis. Of the previously identified patient factors, only receiving a peri-operative transfusion was found to be significant (ρ = 0.24; p = 0.002). None of the other pre-identified variables were found to be significantly correlated with LOS. Variables not previously examined that were found to be significantly correlated with hospital LOS included ASA status (ρ = 0.19, p = 0.046), fusion involving both the thoracic and lumbar spine (ρ = 0.18, p = 0.025), and receiving celecoxib on post-operative day 1 (ρ = - 0.16; p = 0.038). The features that had the greatest association with LOS through multivariable regression was receiving a blood transfusion (B = 0.48; 95%CI 0.096-0.89; p = 0.017). In this study, we found that many of the features found to be significantly correlated with prolonged hospital LOS in the United States are not transferable to the Canadian healthcare system. This is important for the Canadian, and other surgeons in a single-payer system, in order to identify pre-operative or immediate post-operative factors that may extend patient LOS following PSIF and plan resources accordingly.

Validity and reliability of the adapted Dutch version of the Brace Questionnaire (BrQ).

The Brace Questionnaire (BrQ) is a disease-specific health-related quality of life (HRQOL) instrument for measuring perceived health status of scoliosis patients undergoing brace treatment. The purpose of this study is to evaluate the validity and reliability of a translated and culturally adapted Dutch version of the BrQ. The original Greek BrQ was translated into Dutch and a cross-cultural adaptation and validation processes were conducted. Subsequently, 80 adolescent idiopathic scoliosis (AIS) patients undergoing active brace treatment were included from 4 scoliosis centers to evaluate the validity and reliability of the Dutch version of the BrQ. The questionnaire's floor and ceiling effects, internal consistency, and test-retest reliability were assessed. Concurrent validity was evaluated by comparing the BrQ with the revised Scoliosis Research Society 22-item questionnaire (SRS-22r) scores. The mean total BrQ score was 75.9 (standard deviation [SD] 11.3) and the mean domain scores varied between 3.4 (SD 0.9) and 4.2 (SD 0.7) for the domains "vitality" and "bodily pain," respectively. There were no floor and ceiling effects for the total BrQ score. The BrQ showed satisfactory internal consistency in most subdomains with a Cronbach's α ranging between 0.35 for the domain "general health perception" and 0.89 for the domain "self-esteem and aesthetics." Excellent test-retest reproducibility was observed for the total BrQ score (ICC 0.91), and the BrQ was successfully validated against the SRS-22r. The translated and culturally adapted Dutch version of the BrQ is a valid and reliable HRQOL instrument for AIS patients undergoing brace treatment.

A targeted antibody-based array reveals a serum protein signature as biomarker for adolescent idiopathic scoliosis patients

BackgroundEvident adolescent idiopathic scoliosis (AIS) incurs high treatment costs, low quality of life, and many complications. Early screening of AIS is essential to avoid progressing to an evident stage. However, there is no valid serum biomarker for AIS for early screening.MethodsAntibody-based array is a large-scale study of proteins, which is expected to reveal a serum protein signature as biomarker for AIS. There are two segments of the research, including biomarkers screening and validation. In the biomarkers screening group, a total of 16 volunteers participated in this study, and we carried out differentially expressed proteins screening via protein array assay between No-AIS group and the AIS group, through which GeneSet enrichment analysis was performed. In the validation group with a total of 62 volunteers, the differentially expressed proteins from screening group were verified by Enzyme-Linked immunosorbent assay (ELISA), and then multiple regression analysis.ResultsIn our study, there were twenty-nine differentially expressed proteins in AIS, through Protein array assay and GeneSet enrichment analysis in the biomarkers screening group. Then the expression of FAP, CD23 and B2M decreased as the degree of AIS increased via ELISA in validation group (FAP, p < 0.0001; CD23, p = 0.0002; B2M, p < 0.0001). Further, the results of multiple regression analysis showed that FAP, CD23 are linked to Cobb angle, whereas B2M were excluded because of multicollinearity.ConclusionsAltogether, we found that serum protein FAP and CD23 are intimately related to AIS, suggesting FAP and CD23 are expected to serve as the serum biomarkers, which significantly facilitate frequent longitudinal monitoring as to keep track of disease progression and tailor treatment accordingly.

Mean platelet volume and neutrophil/lymphocyte ratio in adolescent idiopathic scoliosis: can they be predictive value in diagnosis?

In our study, we evaluated whether mean platelet volume (MPV) and neutrophil lymphocyte ratio (NLR) are predictive values in the diagnosis of Adolescent Idiopathic Scoliosis in patients diagnosed with scoliosis in our clinic. Approximately 15000 patients who applied to our spine outpatient clinic with the suspicion of scoliosis between 2011 and 2018 were reviewed retrospectively. 292 patients were included in the study. The patients were divided into 3 groups. Group 1; control group group 2; group with the possibility of developing scoliosis under follow-upand group 3; the patient group diagnosed with scoliosis. Spinal curvature degrees of the patients were measured using the Cobb method. The MPV and NLR values of the patients were compared with the degree of curvature measured by the cobb method. NLR was 2.17 ± 2.10 K/ul in Group 1, 2.42 ± 1.76 K/ul in Group 2, and 2.72 ± 3.91 K/ul in Group 3. Although the NLR of the 3rd group was higher than the other 2 groups, it was not statistically significant. (p &gt; 0.05). MPV was 7.90 ± 1.07 fL in Group 1, 7.95 ±1.39 fL in Group 2, 8.33 ± 1.37 fL in Group 3.MPV was higher in Group 3 and was found to be statistically significant (p=0.024). After adjusting for the effects of gender and age variables on the groups, the difference in MPV between groups became more significant (p=0.017) . While there was no statistically significant difference between the groups in terms of NLR, it was observed that MPV was statistically significantly higher in patients with AIS.Could this relationship be a promising inflammatory marker for AIS? We think that this question should be answered by studies involving larger patient and control groups.

Clinician-led mental health conversations significantly associated with outcomes for scoliosis patients.

The psychological impact of idiopathic scoliosis has been well established in the literature. While the diagnosis of scoliosis is concerning, bracing often compounds patients' stress, and patients have expressed wanting to discuss their feelings with their healthcare providers. Counseling can be an effective coping strategy for adolescents facing chronic illness, but it has not been studied in individuals diagnosed with scoliosis. To assess the frequency and effect of counseling and clinician-led mental health discussions on individuals diagnosed with scoliosis in childhood and adolescence. Cross-sectional study. Community-based research, online. Individuals diagnosed with scoliosis in childhood and adolescence. The online survey included the SRS-22r, the BSSQ-Brace, questions about demographics, mental health, the Scolios-us Mentor Program, and general scoliosis experience. The survey was distributed to Scolios-us Mentor Program participants and to scoliosis clinicians to provide to their patients. Responses about mental health, experiences with healthcare providers, and counseling were analyzed for group differences and associations. Fifty-five subjects participated in the study, with a median age of 13 (IQR: 3). Our results indicate that mental health is not being discussed as much as it is desired. A desire to discuss mental health was associated with lower function (P=0.005), mental health (P<0.001), SRS-22r total scores (P=0.002), and BSSQ-Brace scores (P=0.015). Subjects who engaged in a mental health discussion with one or more scoliosis healthcare providers exhibited higher management scores (P=0.002). Only 18.2% of subjects sought counseling, and two-thirds of these subjects found counseling to be very or extremely helpful. Mental health is not discussed by scoliosis providers as often as patients desire it, and a desire to have these conversations is negatively associated with several clinical outcomes. Although clinicians are not regularly talking about mental health, the positive associations of mental health discussions with clinical outcomes are encouraging. The ability to acknowledge the desire to discuss mental health, begin these discussions, and refer patients to a mental health professional may improve patient outcomes.

A feasibility study of applying two-dimensional photogrammetry for screening and monitoring of patients with adolescent idiopathic scoliosis in clinical practice

Standing posteroanterior radiographs have been the golden standard to quantify the severity of scoliosis deformity. However, it exposes ionizing radiation to scoliosis patients, and cannot be used for routine screening and monitoring. This study aimed to develop a protocol of measuring postural indexes by using the noninvasive and radiation-free two-dimensional (2D) photogrammetry method and identify its clinical value in scoliosis screening and monitoring. The five postural indexes were measured from the posterior view of 110 participants. One-way ANOVA with post hoc Tukey HSD/Games–Howell analysis was used to compare the differences between the participants in the scoliosis group and the non-scoliosis group. Pearson coefficients of correlation were analyzed to identify the relationships between Cobb angles and each of the five quantitative postural indexes. Based on 2D photogrammetry, the postural indexes of C7 deviation (p = 0.02), shoulder alignment (p < 0.001), scapula alignment (p < 0.001), waist angle discrepancy (p < 0.001), and PSIS alignment (p < 0.001) could significantly differentiate scoliosis and non-scoliosis patients during screening. The waist angle discrepancy (r = 0.4, p = 0.01; r = 0.8, p = 0.03; r = 0.7, p = 0.01) and shoulder alignment (r = 0.6, p = 0.03) had moderate to strong positive correlations with the Cobb angles, which supported their clinical values in monitoring scoliotic curvature changes of adolescent idiopathic scoliosis (AIS) patients.

Metabolic Imbalances and Bone Remodeling Agents in Adolescent Idiopathic Scoliosis: A Study in Postmenarcheal Girls.

The causes and mechanisms underlying adolescent idiopathic scoliosis (AIS) remain unclear, and the available information regarding metabolic imbalances in AIS is still insufficient. This investigation aimed to evaluate the concentrations of specific bone remodeling-related agents in postmenarcheal girls diagnosed with AIS. The study encompassed thirty-six scoliosis patients and eighteen age-matched healthy individuals assigned to the control group. The patients underwent clinical and radiological examinations to assess the degree of the spinal deformity, type of curvature, and skeletal maturity. Blood and urine samples were collected from all participants and serological markers were measured using an enzyme-linked immunosorbent assay. Our study results demonstrated that the balance of phosphate-calcium and parathormone levels seems normal in individuals with AIS. Furthermore, no statistically significant differences were observed in the content of Klotho protein, osteocalcin, osteoprotegerin, C-terminal telopeptide of type I collagen (CTX), sclerostin, and alkaline phosphatase. Nevertheless, the serum levels of vitamin D (25-OH-D) were lowered, while N-terminal propeptide of type I procollagen (PINP), and fibroblast growth factor-23 (FGF23) were increased in the AIS group, with p-values of 0.044, 0.001, and 0.022, respectively. This finding indicates the potential involvement of these factors in the progression of AIS, which necessitates further studies to uncover the fundamental mechanisms underlying idiopathic scoliosis.

Radiographic and clinical outcomes after definitive spine fusion for skeletally immature patients with idiopathic scoliosis.

To assess the intermediate-term radiographic and clinical outcomes of skeletally immature idiopathic scoliosis (IS) patients that underwent definitive fusion (DF). A retrospective review of patients with IS who were Risser 0 with open tri-radiate cartilages at the time of DF with minimum 5-year follow-up. Outcomes included Scoliosis Research Society (SRS)-30 scores, major Cobb angle, pulmonary function tests (PFTs), and unplanned returns to the operating room (UPROR). Adding-on was defined as progression of the major Cobb angle > 5° or tilt of the lowest instrumented vertebra > 5°. Thirty-two patients (78% female, mean age 12.2 ± 1.3years old, mean preoperative major Cobb 64.8° ± 15.9) were included. Of these patients, 20 (62.5%) experienced adding-on and 6 (18.8%) required a revision surgery to correct their progressive spinal deformity. Adding-on was associated with lower 5-year postoperative SRS scores for appearance (3.7 ± 0.7 vs 4.4 ± 0.3, p = 0.0126), mental health (4.2 ± 0.6 vs 4.6 ± 0.3, p = 0.0464), satisfaction with treatment (4.0 ± 0.8 vs 4.7 ± 0.4, p = 0.0140), and total score (4.0 ± 0.4 vs 4.4 ± 0.2, p = 0.0035). The results of the PFTs did not differ between groups. Patients experienced an average of 0.53 UPROR/patient. DF in skeletally immature patients results in a high rate of adding-on, which adversely affects Health-Related Quality of Life. However, reoperation rates, both planned and unplanned, remain lower when compared to patients undergoing growth-friendly treatment.

An Analysis of Scoliosis in Autism Spectrum Disorder.

Children with autism/Asperger are grouped into the diagnosis of autism spectrum disorder (ASD). It remains uncertain whether children with ASD and scoliosis have radiographic and clinical outcomes similar to idiopathic scoliosis (IS) patients. A single-center, retrospective review of a prospective scoliosis registry evaluated patients who had a posterior spinal fusion±Anterior Spinal Fusion and an underlying diagnosis of ASD between 1990 and 2021. A 2:1 match with AIS patients by age and sex was compared using demographic, radiographic, intraoperative, and SRS-22/30 variables. Thirty patients with ASD (63% male, mean age at surgery 14.6±2.5y) met inclusion criteria, with a follow-up of 2.46±1.00 years. Despite no differences in curve magnitude preoperatively, patients with ASD had a higher percent correction at 2-year follow-up (66% vs. 57%, P =0.01) and improved mean curve magnitude (20±10 degrees) at 2-year follow-up compared with IS patients (27±11 degrees, P <0.01). ASD patients had less lumbar lordosis preoperatively (40±12 vs. 53±14, P <0.01), but there were no significant differences in sagittal parameters at 2-year follow-up. There were no significant differences in the rate of complications at 2-year follow-up between ASD and AIS cohorts. Although patients with ASD exhibited decreased lordosis compared with IS patients preoperatively, their radiographic outcomes at 2-year follow-up were the same. In addition, ASD patients maintained greater curve correction than IS patients at 2 years follow-up. Prognostic retrospective study.

Postoperative complications following Schwab-grade-I versus Schwab-grade-II PCO in treating severe rigid kyphoscoliosis patients: comparative matched-group outcomes with minimum 2-year follow-up

BACKGROUND CONTEXTStandard partial facetectomies, (Smith-Petersen Osteotomy, (SPO), (Schwab-grade-I) and complete facet resection also known as Ponte osteotomy, (PO), (Schwab-grade-II) are narrowly akin and collectively appreciated as posterior column shortening osteotomies (PCOs). The former is considered a gentler osteotomy grade than the latter. The spine literature provides very little information on their comparison regarding perioperative complications and major curve correction rate outcomes. PURPOSETo determine whether Schwab-grade-I PCO (SPO) and Schwab-grade-II PCO (PO) are comparably safe in the surgical management of severe rigid scoliosis or kyphoscoliosis patients. STUDY DESIGN/SETTINGRetrospective single-center comparative clinical study. PATIENT SAMPLEA total of 38 patients with severe rigid scoliosis or kyphoscoliosis were propensity score matched in this study, (SPO-treated); n=21 (55.30%) and (PO-treated); n=17 (44.70%), who underwent primary spinal deformity corrective surgery, respectively. OUTCOME MEASURESOutcomes included demographics, baseline pulmonary functional outcomes, perioperative complications incidence, hospital costs, Oswestry disability index (ODI), and the Scoliosis Research Society-22 (SRS-22) questionnaire scores. METHODSFollowing approval by the Institutional Review Board (IRB) of Beijing Chaoyang Hospital-Affiliated Capital Medical University in Beijing, out of a total of 82 consecutive surgical patients with complete data demonstrating severe and/or rigid spinal deformity, a pool of 38 of the 82 (46.3%) propensity-matched adult (≥18 years) patients with severe rigid scoliosis or kyphoscoliosis defined with a preoperative major curve magnitude of ≥80° on anteroposterior plain radiographs, and flexibility of <25% on bending plain radiographs who underwent primary spinal deformity corrective surgery were retrospectively evaluated. The patients were dichotomized into two osteotomy groups: standard (partial) facetectomy (SPO-treated), n=21 with an average age of 24.67 years, (Schwab-grade-I PCO) and complete facet excision, (PO-treated), (ie, Schwab-grade-II PCO), n=17 with an average age of 23.12 years. The minimum follow-up period was 2 years. Primary outcomes included baseline demographics and clinical features. Secondary outcomes included perioperative [intraoperative, immediate, and 2-year postoperative] complication rates. Tertiary outcomes included perioperative ODI and SRS-22 scores. Statistical analyses were carried out by Student t-test and Pearson's Chi-square test (Fisher's Exact Test), through Python statistical software package. Statistical significance was set at (p<.05). RESULTSOf the 38 matched severe rigid scoliosis or kyphoscoliosis patients, 55.30% (n=21) were SPO-treated and 44.70% (n=17) were PO-treated patients, respectively. The overall average age of patients was 23.97 years, with a female incidence of 76.32%. Major curve correction rates were 49.19% and 57.40% in SPO-treated and PO-treated patients, respectively, (p>.05). Immediately following surgery, comparable overall complication rates of 28.57% (n=6/21) versus 29.41% (n=5/17) were observed in the SPO-treated and PO-treated patients, respectively, (p=.726). We observed incidences of 9.52%, (n=2/21) versus 5.88%, (n=1/17) for surgical intensive care unit (SICU) admission, and incidences of 4.76%, (n=1/21) versus 5.88%, (n=1/17) for cardiopulmonary events in SPO-treated versus PO-treated patients following corrective surgery, respectively, (p>.05). The incidences of neurological deficits in the SPO-treated and PO-treated patients were respectively, 14.29%, (n=3/21) versus 17.65%, (n=3/17) immediately following surgery, (p>.05), and 0.00%, (n=0/21) in SPO-treated versus 14.28%, (n=3/21) in PO-treated patients at ≥2 years postoperative, (p<.05). Among the three patients that reported neurological deficits in the PO-treated group at ≥2 years postoperative, two patients had pre-existing baseline neurological deficits. The ODI score in the PO-treated group was significantly inferior at a minimum 2-year follow-up, (p<.05). CONCLUSIONSIn the current study, both SPO-treated and PO-treated patients demonstrated statistically comparable surgical complications immediately following corrective surgery. Severe rigid kyphoscoliosis patients with preexisting baseline neurological deficits were more inclined to sustain neurological morbidity following corrective surgery. PCO corrective techniques are warranted as safe options for treating patients with severe rigid spine deformity phenotypes.

Pregnancy and Childbirth After Spinal Fusion for Adolescent Idiopathic Scoliosis.

Little data exist on pregnancy and childbirth for adolescent idiopathic scoliosis (AIS) patients treated with a spinal fusion. The current literature relies on data from patients treated with spinal fusion techniques and instrumentation, such as Harrington rods, that are no longer in use. The objective of our study is to understand the effects of spinal fusion in adolescence on pregnancy and childbirth. Prospectively collected data of AIS patients undergoing posterior spinal fusion that were enrolled in a multicenter study who have had a pregnancy and childbirth were reviewed. Results were summarized using descriptive statistics and compared with national averages using χ 2 test of independence. A total of 78 babies were born to 53 AIS patients. As part of their pre-natal care, 24% of patients surveyed reported meeting with an anesthesiologist before delivery. The most common types of delivery were spontaneous vaginal delivery (46%, n=36/78) and planned cesarean section (20%, n=16/78). Compared with the national average, study patients had a higher rate of cesarean delivery ( P =0.021). Of the women who had a spontaneous vaginal birth, 53% had no anesthesia (n=19/36), 19% received intravenous intermittent opioids (n=7/36), and 31% had regional spinal or epidural anesthesia (n=11/36). spontaneous vaginal delivery patients in our study cohort received epidural or spinal anesthesia less frequently than the national average ( P <0.001). Of those (n=26 pregnancies) who did not have regional anesthesia (patients who had no anesthesia or utilized IV intermittent opioids), 19% (n=5 pregnancies) were told by their perinatal providers that it was precluded by previous spine surgery. The majority of AIS patients reported not meeting with an anesthesiologist before giving birth and those who had a planned C-section did so under obstetrician recommendation. The presence of instrumentation after spinal fusion should be avoided with attempted access to the spinal canal but should not dictate a delivery plan. A multidisciplinary team consisting of obstetrician, anesthesiologist, and orthopaedic surgeon can provide the most comprehensive information to empower a patient to make her decisions regarding birth experience anesthesia based on maternal rather than provider preference.

Corrective Maneuvers Used in Different Scoliosis Deformities With the Experience of 72 Operated Patients.

This study aimed to show the correction maneuvers used in scoliosis surgery and give hints and tips on achieving optimal correction with the help of visual content. Seventy-two scoliosis patients with 96 major curves operated between 2011 and 2018 evaluated retrospectively. Seven different correction maneuvers (Ucar convex rod rotation technique, cantilever technique, convex double-rod rotation technique, convex double-rod translation technique, double-rod rotation with coronal bending, convex rod rotation with coronal bending, direct vertebral rotation) were used in these surgeries alone or together. Each method is explained with figures and videos. Type of scoliosis, follow-up time, age, preoperative and postoperative degree of curvature, amount of correction, surgical time, amount of transfusion, hemoglobin level, and hospital stay were evaluated. The mean follow-up was 42.5 (24-108) months, and the mean age was 15.8 (12-29) years. The mean preoperative scoliosis angle of the patients was 75.9 (50-139) degrees, and the final follow-up was 15.6 (5-40) degrees. The scoliotic deformity correction rate was 79.3%. The mean preoperative thoracic kyphosis of the patients was 58.7 (12-110) degrees, and the final follow-up was 41.2 (25-62) degrees. The mean surgical time was 293 (160-440) minutes. The mean hospitalization length was 5.8 (2-21) days. The blood delivered to patients during surgery and postoperative was 715 (300-1800)mL. There was a statistically significant difference between the preoperative and final follow-up scoliosis angle ( P =0.000). Providing an ideal correction without damaging the spinal cord depends on correctly applying the correction maneuvers. The use of correction maneuvers alone or in combination in the appropriate order will shorten the duration of the case, decrease the amount of bleeding, shorten the hospital stay, increase the amount of correction, and reduce complications.

Current Knowledge on the Different Characteristics of Back Pain in Adults with and without Scoliosis: A Systematic Review.

Patients with scoliosis have a high prevalence of back pain (BP). It is possible that scoliosis patients present with specific features when experiencing back or leg pain pathology. The aim of this systematic review is to report the signs, symptoms and associated features of BP in patients with scoliosis compared to adults without scoliosis during adulthood. From inception to 15 May 2023, we searched the following databases: PubMed, EMBASE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Scopus. We found 10,452 titles, selected 25 papers for full-text evaluation and included 8 in the study. We found that scoliosis presents with asymmetrical pain, most often at the curve's apex, eventually radiating to one leg. Radiating symptoms are usually localised on the front side of the thigh (cruralgia) in scoliosis, while sciatica is more frequent in non-scoliosis subjects. These radiating symptoms relate to rotational olisthesis. The type and localization of the curve have an impact, with lumbar and thoracolumbar curves being more painful than thoracic. Pain in adults with scoliosis presents specific features: asymmetrical localization and cruralgia. These were the most specific features. It remains unclear whether pain intensity and duration can differentiate scoliosis and non-scoliosis-related pain in adults.

Novel Enhanced Recovery After Surgery Pathway Reduces Length of Stay and Postoperative Opioid Usage in Adolescent Idiopathic Scoliosis Patients Undergoing Posterior Spinal Fusion.

The goal of this study was to compare our institution's recently implemented enhanced recovery after surgery (ERAS) protocol to previous post-operative management for adolescent idiopathic scoliosispatients undergoing posterior spinal fusion, specifically assessing length of stay, opioid consumption, and pain scores. This is a retrospective analysis that compares the length of stay, opioid consumption, and pain scores of patients undergoing posterior spinal fusion for adolescent idiopathic scoliosis. Patients were analyzedprior to the implementation of our ERAS protocol, deemed the traditional pain pathway (TPP), to those who underwent the ERAS pathway. All patients undergoing posterior spinal fusion for adolescent idiopathic scoliosis were included. Patients were excluded if they weighed less than 40kg, had significant comorbidities, or had non-idiopathic causes of scoliosis. We examined 22 patients in the TPP cohort and 20 in the ERAS cohort. Length of stay in the ERAS cohort was significantly reduced compared to the TPP by 1.7 days (P<0.01). Overall opioid consumption was also significantly reduced in the ERAS with 1.4 ± 0.7 morphine equivalents (ME)/kg compared to the TPP 2.4 ± 1.1 ME/kg (P < 0.01). We found no difference inpain scores between the two groups. Implementation of an ERAS pathway at our institution significantly reduced length of stay and opioid consumption in adolescent idiopathic scoliosis patients undergoing posterior spinal fusion. These outcomes reduce morbidity and costs associated with posterior spinal fusion and provide an overall improvement in the quality of care for our patients.

The incidence and interrelationship of hemivertebra and concomitant cardiac abnormalities in congenital scoliosis

BackgroundCongenital scoliosis(CS) is associated with multiple organs defect, and cardiac abnormalities have been reported commonly associated with CS. Hemivertebra is caused by the failure of vertebral formation, which is a major constitute of CS. Till now, few studies focus on the incidence and interrelationship of hemivertebra and concomitant cardiac abnormalities in congenital scoliosis. We aimed to analyze the cardiac defect in CS patients with or without hemivertebra, and further explore the incidence of cardiac defect between different types of hemivertebra.MethodsThe ultrasonic cardiography (UCG) results of surgically treated congenital scoliosis (CS) patients between 2015 and 2018 were retrospectively analyzed. Patients were divided into hemivertebra group and non-hemivertebra group according to preoperative CT. Patients with hemivertebra was further divided into sub-group by single/multiple or fully/partially/mixed segmented hemivertebra. Demographic information, radiographic data and cardiac abnormalities were statistically compared between groups.ResultsA total of 329 patients were analyzed, including 216 patients with hemivertebra and 113 patients without hemivertebra. UCG results were abnormal in 89 cases (27.1%), including 41 males(12.5%) and 48 females(14.6%). Hemivertebra group had comparable incidence of cardiac abnormalities with non-hemivertebra group (p = 0.517). No significant difference in the incidence of UCG abnormalities between single and multiple hemivertebra group (P = 0.246). Binary logistic regression analysis showed that female sex with multiple hemivertebra was a risk factor for abnormal UCG (P = 0.009, OR = 3.449). Cardiac abnormalities was comparable among fully, partially and mixed segmented hemivertebra group(P = 0.264). In abnormal UCG, 33 patients with hemivertebra had non-valvular abnormalities, and 48.5% (16/33) were septal defects. 28 patients had valvular abnormalities, most of them were mitral valve abnormalities, especially mitral valve redundancy, prolapse and insufficiency(82.1%, 23/28). No significant difference between the incidence of non-valvular and valvular abnormalities in patients with hemivertebra (P = 0.581).ConclusionsThe incidence of abnormal UCG results was approximately 28.2% in CS patients with hemivertebra. Female patients with multiple hemivertebra had a higher risk of UCG abnormalities. Mitral valve abnormalities were the most common abnormality of UCG found in CS patients with hemivertebra.Trial registrationretrospectively registered.

Association of scoliosis with skeletal jaw asymmetry

ObjectiveThe objective of this study was to evaluate the relationship between scoliosis and skeletal jaw asymmetry. MethodsThe subjects were one hundred and thirty-eight (43 male, 95 female) patients with jaw deformity, who underwent surgical orthodontic treatment at Cyubu Rosai Hospital from April 2017 to March 2022, without congenital disease or scoliosis treatment history. Posteroanterior cephalograms and posteroanterior chest radiographs obtained before surgery were used to evaluate horizontal displacement of the jawbone, Cobb angle of scoliosis, respectively. Actual values of spines curved to the right and left of the body and of displacement of the mandible in these directions were both deemed positive and negative, respectively. Correlations between absolute values of spine and jaw displacement, namely values without regard to their direction, and correlations between actual values of spine and jaw displacement were analyzed using Spearman, non-parametric, and Pearson, parametric, tests respectively. ResultsTwenty-two patients (15.9 %) had Cobb angle > 10°. Although there was no significant correlation between Cobb angle and Me angle in the actual values (p = 0.606), there was a significant correlation in the absolute values (p = 0.023). ConclusionsThis study suggests a relationship between horizontal deviation of the mandible and scoliosis in patients with jaw deformity, albeit not necessarily in the same direction.
