RESUMEN
CASE: Spinal deformity associated with Guillain-Barre syndrome (GBS) is not commonly reported. We present a 6-year-old girl who developed kyphoscoliosis after being diagnosed GBS. She had extensive motor deficits requiring 2 hospitalizations and treatment with IV immunoglobulin therapy. Five months after diagnosis, she presented to our clinic with a 15° coronal scoliosis and a 65° thoracic kyphosis. At 6-month follow-up, kyphosis progressed to 77° with no significant change in the coronal curve. At 1 year, sagittal alignment was within normal limits and the coronal curve had completely resolved. CONCLUSION: Spinal deformity in GBS can resolve spontaneously.

PURPOSE: New evidence highlights the significance of 3D in-brace correction for Adolescent Idiopathic Scoliosis (AIS) patients. This study explores how axial parameters relate to treatment failure in braced AIS patients. METHODS: AIS patients (Sanders 1-5) undergoing Rigo-Chêneau bracing at a single institution were included. Axial vertebral rotation (AVR) was determined by utilizing pre-brace and in-brace 3D reconstructions from EOS® radiographs. The primary outcome was treatment failure: surgery or coronal curve progression > 5°. Minimum follow-up was two years. RESULTS: 75 patients (81% female) were included. Mean age at bracing initiation was 12.8 ± 1.3 years and patients had a pre-brace major curve of 31.0° ± 6.5°. 25 patients (76% female) experienced curve progression > 5°, and 18/25 required surgical intervention. The treatment failure group had larger in-brace AVR than the success group (5.8° ± 4.1° vs. 9.9° ± 7.6°, p = 0.003), but also larger initial coronal curve measures. In-brace AVR did not appear to be associated with treatment failure after adjusting for the pre-brace major curve (Hazard Ratio (HR):0.99, 95% Confidence Interval (CI):0.94-1.05, p = 0.833). Adjusting for pre-brace major curve, patients with AVR improvement with bracing had an 85% risk reduction in treatment failure versus those without (HR:0.15, 95% CI:0.02-1.13, p = 0.066). At the final follow-up, 42/50 (84%) patients without progression had Sanders ≥ 7. CONCLUSIONS: While in-brace rotation was not an independent predictor of curve progression (due to its correlation with curve magnitude), improved AVR with bracing was a significant predictor of curve progression. This study is the first step toward investigating the interplay between 3D parameters, skeletal maturity, compliance, and brace efficacy, allowing a future prospective multicenter study. LEVEL OF EVIDENCE: Retrospective study; Level III.
RESUMEN
PURPOSE: Early onset scoliosis (EOS) patient diversity makes outcome prediction challenging. Machine learning offers an innovative approach to analyze patient data and predict results, including LOS in pediatric spinal deformity surgery. METHODS: Children under 10 with EOS were chosen from the American College of Surgeon's NSQIP database. Extended LOS, defined as over 5 days, was predicted using feature selection and machine learning in Python. The best model, determined by the area under the curve (AUC), was optimized and used to create a risk calculator for prolonged LOS. RESULTS: The study included 1587 patients, mostly young (average age: 6.94 ± 2.58 years), with 33.1% experiencing prolonged LOS (n = 526). Most patients were female (59.2%, n = 940), with an average BMI of 17.0 ± 8.7. Factors influencing LOS were operative time, age, BMI, ASA class, levels operated on, etiology, nutritional support, pulmonary and neurologic comorbidities. The gradient boosting model performed best with a test accuracy of 0.723, AUC of 0.630, and a Brier score of 0.189, leading to a patient-specific risk calculator for prolonged LOS. CONCLUSIONS: Machine learning algorithms accurately predict extended LOS across a national patient cohort and characterize key preoperative drivers of increased LOS after PSIF in pediatric patients with EOS.
RESUMEN
OBJECTIVE: Severe scoliosis can affect thoracic organs, potentially leading to cardiovascular abnormalities. Thus, echocardiograms have been suggested for use in preoperative screening in patients with significant scoliosis. However, the utility of preoperative heart screenings in patients without known or suspected heart problems is not well understood. This study aims to find the incidence of cardiac findings in patients with severe scoliosis ≥90° without cardiac history. METHODS: A single-institution retrospective chart review was performed. Inclusion criteria were scoliosis patients with curves ≥90 degrees and a screening echocardiogram performed within 6 months of spine surgery. Patients with a previous cardiac history, diagnosis associated with cardiac comorbidities (eg, connective tissue disease), or major coronal curves <90 degrees were excluded. Echocardiogram reports and perioperative clinical notes from involved services (including orthopaedics, cardiology, and anesthesia) were reviewed. Any postoperative use of vasopressors and reasons for their use were recorded. RESULTS: Overall, 50 patients met the inclusion criteria. The mean age at surgery was 14.0 ± 4.9 years old (range: 2 to 33). The mean major curve was 108 ± 19 degrees (range: 90 to 160 degrees). A normal echocardiogram was seen in 38 (76%), whereas 6 patients (12%) had mild dilation of the aortic sinus or root, 4 (8%) had mild valvular regurgitation, 1 patient had a small atrial septal defect, and 1 had a trace pericardial effusion. No patient had any changes made to their perioperative plan and one patient was advised to see a cardiologist postoperatively. Postoperatively, 8 patients (16%) received vasopressors to raise blood pressure to meet preset goal MAP, but only one of these 8 had a positive echocardiogram (mild valvular insufficiency), which was not seen as a contributing factor to the use of pressors. CONCLUSIONS: This study suggests that screening echocardiograms for patients without a cardiac history or related symptoms does not contribute to the evaluation of perioperative risk or anesthetic management. Creating clear, evidence-based guidelines for the utilization of perioperative testing, like echocardiograms, can reduce the social, time, and financial burdens on families. Such guidelines are vital for appropriate risk assessment and proper utilization of health care resources. LEVEL OF EVIDENCE: Level III.

BACKGROUND: The complexity of health care delivery systems presents a unique challenge for the perioperative space. In the area of arthroplasty procedures, the shift of complex patients into ambulatory surgery centers and reimbursement that is no longer commensurate with the inflated costs of performing these procedures have created difficulties for hospitals and physicians alike. Thus, there is a critical need to optimize perioperative workflows while maintaining high-quality care provision. METHODS: Our institution implemented the Comprehensive Unit-based Safety Program (CUSP) to improve the quality and efficiency of total knee and hip arthroplasties (TKAs and THAs). This initiative involved extensive collaboration with clinical and administrative teams, as well as 5 intervention-driven workgroups. First-case on-time start rates and duration of first-case delays, case length, anesthesia preparation, in-room patient preparation, operation, patient exit, and room turnover after CUSP implementation were analyzed using independent samples median testing, Mann-Whitney U testing, and a percentage-point difference calculation. RESULTS: After CUSP arthroplasty implementation, first-case on-time start rates increased from 43 to 81%. Statistically significant decreases were observed in median times for first-case delays, case length, in-room patient preparation, operation, patient exit, and room turnover for TKAs and THAs, but not anesthesia preparation. CONCLUSIONS: The implementation of CUSP arthroplasty for TKAs and THAs resulted in significant improvements in nearly all efficiency metrics, as well as preventions of patient safety missteps. These results exemplify the versatility of CUSP as a quality improvement method that can maintain patient safety and perioperative efficiency in the arthroplasty service of a large-scale medical center.

BACKGROUND CONTEXT: Intraoperative neurophysiological monitoring (IONM) is used to reduce the risk of spinal cord injury during pediatric spinal deformity surgery. Significant reduction and/or loss of IONM signals without immediate recovery may lead the surgeon to acutely abort the case. The timing of when monitorable signals return remains largely unknown. PURPOSE: The goal of this study was to investigate the correlation between IONM signal loss, clinical examination, and subsequent normalization of IONM signals after aborted pediatric spinal deformity surgery to help determine when it is safe to return to the operating room. STUDY DESIGN/SETTING: This is a multicenter, multidisciplinary, retrospective study of pediatric patients (<18 years old) undergoing spinal deformity surgery whose surgery was aborted due to a significant reduction or loss of IONM potentials. PATIENT SAMPLE: Sixty-six patients less than 18 years old who underwent spinal deformity surgery that was aborted due to IONM signal loss were enrolled into the study. OUTCOME MEASURES: IONM data, operative reports, and clinical examinations were investigated to determine the relationship between IONM loss, clinical examination, recovery of IONM signals, and clinical outcome. METHODS: Information regarding patient demographics, deformity type, clinical history, neurologic and ambulation status, operative details, IONM information (eg, quality of loss [SSEPs, MEPs], laterality, any recovery of signals, etc.), intraoperative wake-up test, postoperative neurologic exam, postoperative imaging, and time to return to the operating were all collected. All factors were analyzed and compared with univariate and multivariate analysis using appropriate statistical analysis. RESULTS: Sixty-six patients were enrolled with a median age of 13 years [IQR 11-14], and the most common sex was female (42/66, 63.6%). Most patients had idiopathic scoliosis (33/66, 50%). The most common causes of IONM loss were screw placement (27/66, 40.9%) followed by rod correction (19/66, 28.8%). All patients had either complete bilateral (39/66, 59.0%), partial bilateral (10/66, 15.2%) or unilateral (17/66, 25.8%) MEP loss leading to termination of the case. Overall, when patients were returned to the operating room 2 weeks postoperatively, nearly 75% (40/55) had monitorable IONM signals. Univariate analysis demonstrated that bilateral SSEP loss (p=.019), bilateral SSEP and MEP loss (p=.022) and delayed clinical neurologic recovery (p=.008) were significantly associated with having unmonitorable IONM signals at repeat surgery. Multivariate regression analysis demonstrated that delayed clinical neurologic recovery (> 72 hours) was significantly associated with unmonitorable IONM signals when returned to the operating room (p=.006). All patients ultimately made a full neurologic recovery. CONCLUSIONS: In children whose spinal deformity surgery was aborted due to intraoperative IONM loss, there was a strong correlation between combined intraoperative SSEP/MEP loss, the magnitude of IONM loss, the timing of clinical recovery, and the time of electrophysiological IONM recovery. The highest likelihood of having a prolonged postoperative neurological deficit and undetectable IONM signals upon return to the OR occurs with bilateral complete loss of SSEPs and MEPs.
RESUMEN
PURPOSE: In 2018, Best Practice Guidelines (BPGs) were published for preventing wrong-level surgery in pediatric spinal deformity, but successful implementation has not been established. The purpose of this study was to evaluate BPG compliance 5 years after publication. We hypothesized higher compliance among BPG authors and among surgeons with more experience, higher caseload, and awareness of the BPGs. METHODS: We queried North American and European surgeons, authors and nonauthors, and members of pediatric spinal study groups on adherence to BPGs using an anonymous survey consisting of 18 Likert scale questions. Respondents provided years in practice, yearly caseload, and guideline awareness. Mean compliance scores (MCS) were developed by correlating Likert responses with MCS scores ("None of the time" = no compliance = MCS 0, "Sometimes" = weak to moderate = MCS 1, "Most of the time" = high = MCS 2, and "All the time" = perfect = MCS 3). RESULTS: Of the 134 respondents, 81.5% reported high or perfect compliance. Average MCS for all guidelines was 2.4 ± 0.4. North American and European surgeons showed no compliance differences (2.4 vs. 2.3, p = 0.07). Authors and nonauthors showed significantly different compliance scores (2.8 vs 2.4, p < 0.001), as did surgeons with and without knowledge of the BPGs (2.5 vs 2.2, p < 0.001). BPG awareness and compliance showed a moderate positive correlation (r = 0.48, p < 0.001), with non-significant associations between compliance and both years in practice (r = 0.41, p = 0.64) and yearly caseload (r = 0.02, p = 0.87). CONCLUSION: Surgeons reported high or perfect compliance 81.5% of the time with BPGs for preventing wrong-level surgery. Authorship and BPG awareness showed increased compliance. Location, study group membership, years in practice, and yearly caseload did not affect compliance. LEVEL OF EVIDENCE: Level V-expert opinion.

PURPOSE: Mehta casting is a potentially curative intervention for early-onset scoliosis (EOS) that typically requires multiple anesthetics. The Food and Drug Administration (FDA) reported that >3 hours of anesthesia under the age of 3 years old may alter brain development; however, no standard exists for the duration of anesthesia during casting. The purpose of this study is to quantify the variability in anesthesia during Mehta casting. We hypothesize that significant institutional variability exists and may be attributed to modifiable factors. METHODS: An EOS registry was used to identify patients who underwent at least one Mehta casting procedure. Anesthesia exposure was quantified, and site variability was assessed by patient characteristics, cast placement, procedure type, and equipment used. RESULTS: Our cohort consisted of 208 patients from 5 institutions (age 2.6±1.4 y). There were 1097 Mehta casting procedures, with 5.4±3.6 castings per patient. Of these patients, 106 (51%) were female, with an average age of 2.11±1.29 years old at the time casting was initiated. Patient etiologies included 154 idiopathic (74.0%), 22 syndromic (10.6%), 18 congenital (8.7%), 11 neuromuscular (5.3%), and 3 unknown (1.4%). Anesthesia time was 69±31 minutes and varied significantly between sites (59±14 to 117±46 min; P <0.001). Cumulative anesthesia time for patients under 3 years was 320±197 minutes with 120/161 (74.5%) patients exceeding 3 hours. Anesthesia time was lower after the FDA warning in 2016 compared with pre-2016 (71±30 vs. 66±32, P =0.008). CONCLUSIONS: Patients undergoing Mehta casting are at significant risk of exceeding 3 hours of anesthesia, which the FDA has stated may be harmful for children <3 years. Significant site variability indicates that standardization protocols should be developed to encourage best practices and minimize anesthetic times. LEVEL OF EVIDENCE: Prognostic Level II.

PURPOSE: Best Practice Guidelines (BPGs) were published one decade ago to decrease surgical site infection (SSI) in pediatric spinal deformity. Successful implementation has not been established. This study evaluated surgeon compliance with items on the BPG. We hypothesized that BPG authors and surgeons with more experience, higher caseload, and awareness of the BPG would have higher compliance. METHODS: We queried North American and European surgeons, authors and non-authors, and members of various spine study groups on adherence to BPGs using an anonymous survey. Mean compliance scores (MCSs) were developed by correlating Likert responses with MCSs ("None of the time" = no compliance = MCS 0, "Sometimes" = weak to moderate = MCS 1, "Most of the time" = high = MCS 2, "All the time" = perfect = MCS 3). RESULTS: Of the 142 respondents, 73.7% reported high or perfect compliance. Average compliance scores for all guidelines was 2.2 ± 0.4. There were significantly different compliance scores between North American and European surgeons (2.3 vs 1.8, p < 0.001), authors and non-authors (2.5 vs. 2.2, p = 0.023), and surgeons with and without knowledge of the BPGs (2.3 vs. 1.8, p < 0.001). There was a weak correlation between BPG awareness and compliance (r = 0.34, p < 0.001) and no correlation between years in practice (r = 0.0, p = 0.37) or yearly caseload (r = 0.2, p = 0.78) with compliance. CONCLUSIONS: Compliance among our cohort of surgeons surveyed was high. North American surgeons, authors of the BPGs and those aware of the guidelines had increased compliance. Participation in a spine study group, years in practice, and yearly caseload were not associated with compliance. LEVEL OF EVIDENCE: Level V-expert opinion.

BACKGROUND: Assessing the quality of life (QOL) of children with early onset scoliosis (EOS) has been discussed recently. Therefore, the study aimed to apply and correlate the 24-item Early Onset Scoliosis Questionnaire (EOSQ-24) with the 50-item Childhood Health Questionnaire (CHQ-PF50) to find predictive factors impacting QOL. METHODS: Cross-sectional study involving a population of caregivers of patients with EOS. The sample consisted of 72 patients. Two research assistants applied the Portuguese version of the EOSQ-24 and CHQ-PF50 in 3 treatment centers. The EOSQ-24 assesses the subjective response of children with EOS from the parent's point of view. The CHQ is a self-administered questionnaire or parental proxy assessment of the psychological and social status of children aged 5 to 18 years. RESULTS: Of 72 patients, 41 (56.9%) were females, mean age of 11.9 ± 4.2 years. The most common scoliosis was of neuromuscular origin (32%). The CHQ-PF50 showed that family-related items had significant scores. The most affected subcategory was physical function (45.5), and the least affected was mental health (90.8). Thus, the CHQ-PF50 PhS summary index was 27, and the CHQ-PF50 PsS was 71.7. Moreover, the critical categories for the EOSQ-24 questionnaire were daily life and physical function (45.1 and 47.8, respectively), and the least affected categories were transfer and pulmonary function (70.8 and 68.9, respectively). Four subcategories showed a strong correlation between both questionnaires: general health (r = 0.749, P < 0.001), physical function (r = 0.645, P < 0.001), bodily pain (r = 0.714, P < 0.001), and mental health (r = 0.424, P < 0.001). Using CHQ-PF50 as a dependent variable in multiple regression analysis (P = 0.028), the only variable affecting the scores was syndromic scoliosis (P = 0.019; 95% CI -27.4 to -2.5). CONCLUSION: A strong correlation between both questionnaires was seen for general health, physical function, bodily pain, and mental health. Syndromic scoliosis was a predictor of worse QOL according to the CHQ-PF50.
RESUMEN
BACKGROUND: Surgical site infection (SSI) is a major potential complication following pediatric spinal deformity surgery that is associated with significant morbidity and increased costs. Despite this, SSI rates remain high and variable across institutions, in part due to a lack of up-to-date, comprehensive prevention, and treatment protocols. Furthermore, few attempts have been made to review the optimal diagnostic modalities and treatment strategies for SSI following scoliosis surgery. The aim of this study was to systematically review current literature on risk factors for SSI in pediatric patients undergoing scoliosis surgery, as well as strategies for prevention, diagnosis, and treatment. METHODS: On January 19, 2022, a systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies reporting risk factors for acute, deep SSI (<90 d) or strategies for prevention, diagnosis, or treatment of SSI following pediatric scoliosis surgery were included. Each included article was assigned a level of evidence rating based on study design and quality. Extracted findings were organized into risk factors, preventive strategies, diagnostic modalities, and treatment options and each piece of evidence was graded based on quality, quantity, and consistency of underlying data. RESULTS: A total of 77 studies met the inclusion criteria and were included in this systematic review, of which 2 were categorized as Level I, 3 as Level II, 64 as Level III, and 8 as Level IV. From these studies, a total of 29 pieces of evidence (grade C or higher) regarding SSI risk factors, prevention, diagnosis, or treatment were synthesized. CONCLUSIONS: We present an updated review of published evidence for defining high-risk patients and preventing, diagnosing, and treating SSI after pediatric scoliosis surgery. The collated evidence presented herein may help limit variability in practice and decrease the incidence of SSI in pediatric spine surgery. LEVEL OF EVIDENCE: Level III-systematic review.

PURPOSE: It is currently unknown how treatment preferences differ between a senior group of U.S. spinal surgeons, a new generation of U.S. surgeons, and non-U.S. surgeons with regard to the treatment of early-onset scoliosis (EOS). The purpose of this study was to evaluate clinical consensus and uncertainty among treatment options for patients with EOS to understand how they compare between these three cohorts. METHODS: 11 senior pediatric spinal deformity surgeons in the U.S., 12 "junior" surgeons in the U.S., and 7 surgeons practicing in non-U.S. countries were invited to complete a survey of 315 idiopathic and neuromuscular EOS case scenarios. Treatment options included: conservative management, distraction-based methods, growth guidance/modulation, and arthrodesis. Consensus was defined as ≥ 70% agreement, and uncertainty was < 70%. Chi-squared and multiple regression analyses were performed to evaluate the associations between case characteristics and consensus for different treatments. RESULTS: Although all 3 cohorts of surgeons chose conservative management most frequently, the non-U.S. cohort of surgeons chose distraction-based methods more often, particularly for neuromuscular cases. In both U.S. surgeon cohorts, there was consensus for conservative management in idiopathic patients aged 3 or younger regardless of other factors, whereas non-U.S. surgeons selected distraction-based methods for some of these patients. CONCLUSION: Just as research studies are being conducted to find approaches to optimally manage the EOS population, future research efforts should focus on identifying the reasoning behind treatment preferences in different cohort of surgeons, as this will allow the interexchange of information which can ultimately improve EOS care.

PURPOSE: This study sought to investigate associations between upper instrumented vertebra (UIV) location and the risk of proximal junctional kyphosis (PJK) at 2 years following posterior spinal fusion (PSF) for Scheuermann's kyphosis (SK). METHODS: In this retrospective cohort study, SK patients who underwent PSF and reached 2 years postop were identified in a multicenter international registry, excluding those with anterior release, prior spine surgery, neuromuscular comorbidity, post-traumatic kyphosis, or kyphosis apex below T11-T12. Location of UIV as well as the number of levels between UIV and preoperative kyphosis apex was determined. Additionally, the degree of kyphosis correction was evaluated. PJK was defined as a proximal junctional angle ≥ 10° that is ≥ 10° greater than the preoperative measurement. RESULTS: 90 patients (16.5 ± 1.9 yo, 65.6% male) were included. Preoperative and 2-year postoperative major kyphosis was 74.6 ± 11.6° and 45.9 ± 10.5°, respectively. Twenty-two (24.4%) patients developed PJK at 2 years. Patients with UIV below T2 had a 2.09 times increased risk of PJK when compared to those with UIV at or above T2, adjusting for distance between UIV and preoperative kyphosis apex [95% Confidence Interval (CI) 0.94; 4.63, p = 0.070]. Patients with UIV ≤ 4.5 vertebrae from the apex had a 1.57 times increased risk of PJK, adjusting for UIV relative to T2 [95% CI 0.64; 3.87, p = 0.326]. CONCLUSION: SK patients with UIV below T2 had an increased risk of developing PJK at 2 years following PSF. This association supports consideration of UIV location during preoperative planning. LEVEL OF EVIDENCE: Prognostic Level II.

OBJECTIVE: The focus of this modified Delphi study was to investigate and build consensus regarding the medical management of children with moderate and severe acute spinal cord injury (SCI) during their initial inpatient hospitalization. This impetus for the study was based on the AANS/CNS guidelines for pediatric SCI published in 2013, which indicated that there was no consensus provided in the literature describing the medical management of pediatric patients with SCIs. METHODS: An international, multidisciplinary group of 19 physicians, including pediatric neurosurgeons, orthopedic surgeons, and intensivists, were asked to participate. The authors chose to include both complete and incomplete injuries with traumatic as well as iatrogenic etiologies (e.g., spinal deformity surgery, spinal traction, intradural spinal surgery, etc.) due to the overall low incidence of pediatric SCI, potentially similar pathophysiology, and scarce literature exploring whether different etiologies of SCI should be managed differently. An initial survey of current practices was administered, and based on the responses, a follow-up survey of potential consensus statements was distributed. Consensus was defined as ≥ 80% of participants reaching agreement on a 4-point Likert scale (strongly agree, agree, disagree, strongly disagree). A final meeting was held virtually to generate final consensus statements. RESULTS: Following the final Delphi round, 35 statements reached consensus after modification and consolidation of previous statements. Statements were categorized into the following eight sections: inpatient care unit, spinal immobilization, pharmacological management, cardiopulmonary management, venous thromboembolism prophylaxis, genitourinary management, gastrointestinal/nutritional management, and pressure ulcer prophylaxis. All participants stated that they would be willing or somewhat willing to change their practices based on consensus guidelines. CONCLUSIONS: General management strategies were similar for both iatrogenic (e.g., spinal deformity, traction, etc.) and traumatic SCIs. Steroids were recommended only for injury after intradural surgery, not after acute traumatic or iatrogenic extradural surgery. Consensus was reached that mean arterial pressure ranges are preferred for blood pressure targets following SCI, with goals between 80 and 90 mm Hg for children at least 6 years of age. Further multicenter study of steroid use following acute neuromonitoring changes was recommended.
RESUMEN
PURPOSE: The purpose of this study was to determine the feasibility and efficacy of a United States multi-site randomized control trial (RCT) of the Schroth-based therapy program in Risser 0 patients with mild adolescent idiopathic scoliosis (AIS) curves. METHODS: Six sites enrolled 98 Risser 0 patients with single AIS curves between 12° and 24°. Patients were randomized to Exercise:Control group in a 2:1 ratio. Exercise group patients were instructed on the Schroth-based method and a home exercise program of 75 min/week for 1 year. RESULTS: Enrollment across 6 institutions averaged 2.2 patients per month over 45 months. Patient attrition was 42% after 1 year (41/98) and 52% after 2 years (51/98). Exercise group patients were significantly younger (11.6 vs 12.5 years) without differences in the baseline Cobb angle (16.2° vs 17.1°). Self-reported exercise adherence averaged 82% at 6 months and 63% at 1 year (n = 35). A significantly lower frequency of patients was braced in the Exercise group after 1 year (26% vs 55%, p = 0.03) but not after 2 years (48% vs 63%, p = 0.31). Curve magnitude changes between groups were not significant after 1 and 2 years. CONCLUSION: Performing a multi-site RCT for mild AIS in the United States is challenging with slow enrollment and high attrition. Young patients with small curves have difficulty adhering to the intensive demands of Schroth-based therapy. LEVEL OF EVIDENCE: II.

BACKGROUND: The term "Tweener" is colloquially used to refer to early-onset scoliosis (EOS) patients whose age and development make them candidates for multiple surgical options. The purpose of this study was to establish expert consensus on a definition to formally characterize the Tweener population. METHODS: A 3-round survey of surgeons in an international EOS study group was conducted. Surgeons were provided with various patient characteristics and asked if each was part of their definition for Tweener patients. Responses were analyzed for consensus (≥70%), near-consensus (60% to 69%), and no consensus (<60%). RESULTS: Consensus was reached (89% of respondents) for including chronological age in the Tweener definition; 8 to 10 years for females and 9 to 11 years for males. Surgeons agreed for inclusion of Sanders score, particularly Sanders 2 (86.0%). Patients who have reached Sanders 4, postmenarche, or have closed triradiate cartilage should not be considered Tweeners. Bone age range of 8 years and 10 months to 10 years and 10 months for females (12 y for males) could be part of the Tweener definition. CONCLUSIONS: This study suggests that the Tweener definition could be the following: patients with open triradiate cartilage who are not postmenarche and have not reached Sanders 4, and if they have one of the following: Sanders 2 or chronological age 8 to 10 years for females (9 to 11 y for males) or bone age 8 years and 10 months to 10 years and 10 months for females (12 y for males). This definition will allow for more focused and comparative research on this population. LEVEL OF EVIDENCE: Level V-expert opinion.

BACKGROUND: The study sought to evaluate the utility of a single supine radiograph in determining curve flexibility in early-onset scoliosis (EOS) patients. METHODS: EOS patients with upright (standing/seated), supine, and side-bending radiographs who underwent spinal deformity surgery were identified. Coronal parameters included: proximal thoracic (PT) curve, main thoracic (MT) curve, and thoracolumbar/lumbar (TL/L) curve. Each radiograph was measured twice by 2 different raters. Correlation coefficients were utilized to investigate associations between the different radiographs. Interrater Correlation Coefficient (ICC) assessed intrarater and interrater reliability. RESULTS: Thirty-seven EOS patients were identified (age at diagnosis: 7.0±2.9 y, preoperative age: 13.0±2.9 y; 73% female; etiologies: 54% idiopathic, 30% syndromic, and 16% neuromuscular). Supine PT and MT curve measurements were highly associated with corresponding side-bending measurements (PT: r=0.75, P<0.001; MT: r=0.80, P<0.001), and TL/L curves were very highly associated (TL/L: r=0.92, P<0.001). The mean absolute differences between supine and side-bending measurements were PT: 11.3±7.8 degrees, MT: 14.8±8.3 degrees, and TL/L: 16.2±7.6 degrees, where the side-bending was on average smaller than the supine measurement. The intrarater reliabilities were excellent, with an ICC ranging from 0.93 to 0.96 for side-bending films and 0.94 to 0.97 for supine films. The interrater reliability was excellent with ICC value of 0.88 for side-bending films and 0.93 for supine films. CONCLUSIONS: A single, preoperative supine radiograph was highly predictive of side-bending radiographs in patients with EOS. Supine curves measured an average of 15 degrees larger than bending curves in the MT and TL/L region. A single supine film may eliminate the need for effort-related, dual side-bending radiographs. LEVEL OF EVIDENCE: Level II-retrospective study.

PURPOSE: While the C-EOS system helps organize and classify Early Onset Scoliosis (EOS) pathology, it is not data-driven and does not help achieve consensus for surgical treatment. The current study aims to create an automated method to cluster EOS patients based on pre-operative clinical indices. METHODS: A total of 1114 EOS patients were used for the study, with the following distribution by etiology: congenital (240), idiopathic (217), neuromuscular (417), syndromic (240). Pre-operative clinical indices used for clustering were age, major curve (Cobb) angle, kyphosis, number of levels involved in a major curve (Cobb angle) and kyphosis along with deformity index (defined as the ratio of major Cobb angle and kyphosis). Fuzzy C-means clustering was performed for each etiology individually, with one-way ANOVA performed to assess statistical significance (p < 0.05). RESULTS: The automated clustering method resulted in three clusters per etiology as the optimal number based on the highest average membership values. Statistical analyses showed that the clusters were significantly different for all the clinical indices within and between etiologies.

CONCLUSION: An automated method to cluster EOS patients based on pre-operative clinical indices was developed identifying three unique, data-driven subgroups for each C-EOS etiology category. Adoption of such an automated clustering framework can help improve the standardization of clinical decision-making for EOS.
