RESUMEN
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. LEVEL OF EVIDENCE: III.

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.

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.

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.

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.

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.

AIM: To develop and validate a risk calculator based on preoperative factors to predict the probability of surgical site infection (SSI) in patients with cerebral palsy (CP) undergoing spinal surgery. METHOD: This was a multicenter retrospective cohort study of pediatric patients with CP who underwent spinal fusion. In the development stage, preoperative known factors were collected, and a risk calculator was developed by comparing multiple models and choosing the model with the highest discrimination and calibration abilities. This model was then tested with a separate population in the validation stage. RESULTS: Among the 255 patients in the development stage, risk of SSI was 11%. A final prediction model included non-ambulatory status (odds ratio [OR] 4.0), diaper dependence (OR 2.5), age younger than 12 years (OR 2.5), major coronal curve magnitude greater than 90° (OR 1.3), behavioral disorder/delay (OR 1.3), and revision surgery (OR 1.3) as risk factors. This model had a predictive ability of 73.4% for SSI, along with excellent calibration ability (p = 0.878). Among the 390 patients in the validation stage, risk of SSI was 8.2%. The discrimination of the model in the validation phase was 0.743 and calibration was p = 0.435, indicating 74.3% predictive ability and no difference between predicted and observed values. INTERPRETATION: This study provides a risk calculator to identify the risk of SSI after spine surgery for patients with CP. This will allow us to enhance decision-making and patient care while providing valid hospital comparisons, public reporting mechanisms, and reimbursement determinations.

PURPOSE: Studies have shown that bracing is an effective treatment for patients with idiopathic scoliosis. According to the current classification, almost all braces fall in the thoracolumbosacral orthosis (TLSO) category. Consequently, the generalization of scientific results is either impossible or misleading. This study aims to produce a classification of the brace types. METHODS: Four scientific societies (SOSORT, SRS, ISPO, and POSNA) invited all their members to be part of the study. Six level 1 experts developed the initial classifications. At a consensus meeting with 26 other experts and societies' officials, thematic analysis and general discussion allowed to define the classification (minimum 80% agreement). The classification was applied to the braces published in the literature and officially approved by the 4 scientific societies and by ESPRM. RESULTS: The classification is based on the following classificatory items: anatomy (CTLSO, TLSO, LSO), rigidity (very rigid, rigid, elastic), primary corrective plane (frontal, sagittal, transverse, frontal & sagittal, frontal & transverse, sagittal & transverse, three-dimensional), construction-valves (monocot, bivalve, multisegmented), construction-closure (dorsal, lateral, ventral), and primary action (bending, detorsion, elongation, movement, push-up, three points). The experts developed a definition for each item and were able to classify the 15 published braces into nine groups. CONCLUSION: The classification is based on the best current expertise (the lowest level of evidence). Experts recognize that this is the first edition and will change with future understanding and research. The broad application of this classification could have value for brace research, education, clinical practice, and growth in this field.

BACKGROUND: The purpose of this study was to report mortality and associated risk factors in neuromuscular early onset scoliosis following spinal deformity surgery. METHODS: This is a multicenter retrospective cohort study of patients with cerebral palsy (CP), spinal muscular atrophy, myelodysplasia, muscular dystrophy, or myopathy undergoing index spine surgery from 1994 to 2020. Mortality risk was calculated up to 10 years postoperatively. Proportional hazard modeling was utilized to investigate associations between risk factors and mortality rate. RESULTS: A total of 808 patients [mean age 7.7 y; 439 (54.3%) female] were identified. Postoperative 30-day, 90-day, and 120-day mortality was 0%, 0.001%, and 0.01%, respectively. 1-year, 2-year, 5-year, and 10-year mortality was 0.5%, 1.1%, 5.4%, and 17.4%, respectively. Factors associated with increased mortality rate: CP diagnosis [hazard ratio (HR): 3.14, 95% confidence interval (CI): 1.71; 5.79, P<0.001]; nonambulatory status (HR: 3.01, 95% CI: 1.06; 8.5, P=0.04)]; need for respiratory assistance (HR: 2.17, 95% CI: 1.00; 4.69, P=0.05). CONCLUSIONS: In neuromuscular patients with early onset scoliosis, mortality risk at 10 years following spine surgery was 17.4%. As mortality was 1.1% at 2 years, premature death was unlikely a direct result of spine surgery. Diagnosis (CP) and markers of disease severity (nonambulatory status, respiratory assistance) were associated with increased mortality rate. LEVEL OF EVIDENCE: Prognostic level II.

INTRODUCTION: Due to a combination of poor respiratory muscle control and mechanical lung compression secondary to spine and chest wall deformities, patients with neuromuscular (NM) early-onset scoliosis (EOS) are at a high risk for pulmonary complications including pneumonia. The purpose of this study is to examine the effect of surgical intervention on the prevalence and risk of postoperative pneumonia in patients with NM EOS. METHODS: In this retrospective cohort study, pediatric (18 y old and below) patients with NM EOS undergoing index fusion or growth-friendly instrumentation from 2000 to 2018 were identified. Patients were then categorized into 2 groups: those with ≥50% curve correction and those with <50% curve correction of the coronal deformity at the first postoperative visit. The primary outcome of interest was postoperative pneumonia occurring between 3 weeks and 2 years postoperatively. Manual chart review was supplemented with phone call surveys to ensure all occurrences of preoperative/postoperative pneumonia (ie, in-institution and out-of-institution visits) were accounted for. RESULTS: A total of 35 patients (31% female, age at surgery: 10.3±4.3 y) with NM EOS met inclusion criteria. Twenty-three (66%) patients experienced at least 1 case of preoperative pneumonia. Twenty-six (74%) patients had ≥50% and 9 (26%) patients had <50% immediate postoperative curve correction. In total, 12 (34%) patients experienced at least 1 case of postoperative pneumonia (7 in-institution, 5 out-of-institution). Seven (27%) patients with ≥50% curve correction versus 5 (56%) with <50% curve correction experienced postoperative pneumonia. Relative risk regression demonstrated that patients with <50% curve correction had increased risk of postoperative pneumonia by 2.1 times compared with patients with ≥50% curve correction (95% confidence interval: 0.9; 4.9, P =0.099). CONCLUSION: The prevalence of preoperative and postoperative pneumonia is high in patients with NM EOS. This study presents preliminary evidence suggesting that percent curve correction is associated with the occurrence of postoperative pneumonia in patients with NM EOS undergoing surgical correction.

BACKGROUND: Addressing operational inefficiencies in operating rooms (ORs) enhances patient access to care, reduces delays, and improves employee and patient satisfaction. The Comprehensive Unit-based Safety Program (CUSP) promotes patient safety through increased teamwork, empowerment of frontline staff, and utilization of science of safety principles. CUSP has demonstrated success in outpatient and inpatient settings to decrease complication rates and establish a culture of safety but has been used minimally in the perioperative setting. In this study, the CUSP methodology was utilized to improve perioperative efficiency in pediatric spine surgery, and preimplementation and postimplementation efficiency were compared, using the rate of first case on-time starts (FCOTS) as the primary metric. METHODS: A CUSP quality improvement workgroup including nurses, technicians, surgeons, anesthesiologists, and administrators sought feedback on opportunities for improvement and tracked key performance metrics in the OR from 2015 to 2020. Key interventions developed in response to feedback included standardizing and streamlining room setup and adjusting staffing models for greater efficiency. Univariate analysis was conducted to compare time periods pre-CUSP and post-CUSP implementation. RESULTS: First case on-time starts increased from 38% to a high of 81% after implementation. For more complex cases, the average patient in the room to anesthesia ready time improved by 31% with decreased variance over time, and average closure to patient out of room time improved by 45%. Improvements were sustained through Year 3, while CUSP remained a primary focus for the team. CONCLUSIONS: CUSP is effective in enhancing perioperative efficiency, demonstrating strong improvement in on-time starts over 5 years. The results indicate that process improvement in ORs requires consistent attention to sustain gains over time. Engaging frontline staff in quality improvement fosters collaboration and provides employee buy-in to promoting a culture of safety and improving value in patient care. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

BACKGROUND: The purpose of this study was to utilize a multicenter, multisurgeon cohort to assess the effect of surgeon experience on outcomes of growth friendly instrumentation (GFI) in early onset scoliosis (EOS). We hypothesized that unplanned return to the operating room (UPROR), estimated blood loss (EBL), and surgical time would be greater amongst early career surgeons (ECSs) when compared with advanced career surgeons (ACSs). METHODS: An international pediatric spine database was queried for patients ages 2 to 10 years treated by posterior distraction-based GFI with at least of 2-year follow up. Two groups were created for analysis based on surgeon experience: ECSs (with ≤10 y of experience) and ACSs (with >10 y of experience). The primary outcome was UPROR. Additional outcomes included: operating room time, EBL, neurological deficits, infection rate, hardware failure, and the Early Onset Scoliosis Questionnaire (EOSQ-24). Subgroup analysis was performed for further assessment based on procedure type, superior anchor type, etiology, and curve severity. RESULTS: A total of 960 patients met inclusion criteria including 243 (25.3%) treated by ECS. Etiology, sex, superior anchor, and EOSQ-24 scores were similar between groups (P>0.05). There were no clinically significant differences in patient age or preoperative major coronal curve. UPROR (35.8% vs. 32.7%, P=0.532), infection (17.0% vs. 15.6%, P=0.698), operating room time (235 vs. 231 min, P=0.755), and EBL (151 vs. 155 mL, P=0.833) were comparable between ECS and ACS groups. The frequency of having at least 1 complication was relatively high but comparable among groups (60.7% vs. 62.6%, P=0.709). EOSQ-24 subdomain scores were similar between groups at 2-year follow-up (P>0.05). Subgroup analysis revealed that ECS had increased surgical time compared with ACS in severe curves >90 degrees (270 vs. 229 min, P=0.05). CONCLUSIONS: This study represents the first multicenter assessment of surgeon experience on outcomes in EOS. Overall, surgeon experience did not significantly influence UPROR, complication rates, EBL, or surgical time associated with GFI in this cohort of EOS patients. LEVEL OF EVIDENCE: Level III.

BACKGROUND: The outcomes of congenital scoliosis (CS) patients undergoing hemivertebra (HV) resection surgery with a 2-level fusion versus a >2-level fusion are unclear. We hypothesized that CS patients undergoing HV resection and a >2-level fusion have decreased curve progression and reoperation rates compared with 2-level fusions. METHODS: Retrospective review of prospectively collected data from a multicenter scoliosis database. Fifty-three CS patients (average age 4.5, range 1.2 to 10.9 y) at index surgery were included. Radiographic and surgical parameters, complications, as well as revision surgery rates were tracked at a minimum of 2-year follow-up. RESULTS: Twenty-six patients had a 2-level fusion while 27 patients had a >2-level fusion with similar age and body mass index between groups. The HV was located in the lumbar spine for 69% (18/26) 2-level fusions and 30% (8/27) >2-level fusions ( P =0.006). Segmental HV scoliosis curve was smaller in 2-level fusions compared to >2-level fusions preoperatively (38 vs. 50 degrees, P =0.016) and at follow-up (25 vs. 34 degrees, P =0.038). Preoperative T2-T12 (28 vs. 41 degrees, P =0.013) and segmental kyphosis (11 vs. 23 degrees, P =0.046) were smaller in 2-level fusions, but did not differ significantly at postoperative follow-up (32 vs. 39 degrees, P =0.22; 13 vs. 11 degrees, P =0.64, respectively). Furthermore, the 2 groups did not significantly differ in terms of surgical complications (27% vs. 22%, P =0.69; 2-level fusion vs. >2-level fusion, respectively), unplanned revision surgery rate (23% vs. 22%, 0.94), growing rod placement or extension of spinal fusion (15% vs. 15%, P =0.95), or health-related quality of life per the EOS-Questionnaire 24 (EOSQ-24). Comparison of patients with or without the need for growing rod placement or posterior spinal fusion revealed no significant differences in all parameters analyzed. CONCLUSIONS: Two-level and >2-level fusions can control congenital curves successfully. No differences existed in curve correction, proximal junctional kyphosis or complications between short and long-level fusion after HV resection. Both short and long level fusions are viable options and generate similar risk of revision. The decision should be individualized by patient and surgeon.

BACKGROUND: Limiting complications, especially unplanned return to the operating room (UPROR), is a major focus in the surgical management of early-onset scoliosis (EOS). Although UPROR remains common in this population, its effect on long-term health-related quality of life (HRQoL) remains unclear. The purpose of this study was to investigate the association between UPROR and end-of-treatment HRQoL in EOS patients treated with growth-friendly instrumentation. METHODS: Patients with EOS who underwent growth-friendly instrumentation at age less than 10 years from 1993 to 2018, and completed treatment, were identified in a multicenter EOS registry. UPROR events were recorded, and end-of-treatment (defined as skeletal maturity and/or definitive spinal fusion) HRQoL was assessed via the 24-item Early-Onset Scoliosis Questionnaire (EOSQ-24). RESULTS: A total of 825 patients were identified, and 325 patients (age at surgery: 6.4 y, follow-up: 8.1 y) had end-of-treatment HRQoL data necessary for our investigation. Overall, 129/325 (39.7%) patients experienced 264 UPROR events; the majority (54.2%) were implant-related. Aside from age and etiology, no other variables were determined to be confounders or effect modifiers. Congenital patients with UPROR had worse pain/discomfort by 10.4 points (P=0.057) and worse pulmonary function by 7.8 points (P=0.102) compared with non-UPROR patients adjusting for age. Neuromuscular patients with UPROR had worse pulmonary function by 10.1 points compared with non-UPROR patients adjusting for age (P=0.037). Idiopathic and syndromic patients with UPROR reported consistently worse domain scores than their non-UPROR counterparts, but smaller (<5-point) differences were seen. CONCLUSIONS: UPROR during growth-friendly surgical treatment for EOS is associated with worse HRQoL in all patients, but particularly in those with neuromuscular or congenital etiologies. Ongoing efforts to avoid UPROR are critical. LEVEL OF EVIDENCE: Level II. This is a multicenter retrospective cohort study investigating the effect of UPROR on HRQoL (prognostic study).

BACKGROUND: While largely of concern in nonambulatory patients, pelvic obliquity (PO) can be found in many patients with early onset scoliosis (EOS) and may remain following surgery. However, its association with health-related quality of life (HRQoL) in children and their caregivers at the end of treatment is not well understood. The purpose of this study was to investigate the association between residual PO and HRQoL in children and their caregivers at the end of surgical treatment in ambulatory patients with EOS. METHODS: In this retrospective cohort study, a multicenter EOS registry was queried to identify ambulatory patients who underwent definitive posterior spinal fusion (PSF) from 2012 to 2019. Patients with fusions extending to the pelvis were excluded. PO was measured at least 1 year following PSF. HRQoL, Parental Burden, Financial Burden, and Satisfaction were assessed through the 24-Item Early Onset Scoliosis Questionnaire (EOSQ-24) also at a minimum of 1 year following PSF. RESULTS: A total of 155 patients (12.5±2.1 y, 73.5% female) were included. Etiology distribution was 30.3% congenital, 12.9% neuromuscular, 21.3% syndromic, and 35.5% idiopathic. In congenital patients, those with residual PO >8 degrees had worse Satisfaction by 23.2 points compared with those with PO ≤8 degrees. In neuromuscular patients, those with residual PO >7 degrees had worse HRQoL by 16.1 points and Parental Burden by 22.3 points compared with their counterparts. In syndromic patients, those with residual PO >8 degrees had worse HRQoL by 14.8 points, Parental Burden by 16.4 points, and Satisfaction by 21.2 points compared with their counterparts. In idiopathic patients, those with >9 degrees of residual PO had worse HRQoL by 15.0 points and Financial Burden by 26.8 points compared with their counterparts. CONCLUSIONS: Remaining PO at the end of surgical treatment is associated with worse HRQoL in ambulatory children and their caregivers. These results suggest that correction of PO should remain a primary goal of treatment in patients with EOS undergoing surgery. LEVEL OF EVIDENCE: Level II-multicenter retrospective cohort study investigating prognosis.

PURPOSE: Patients with spinal muscular atrophy (SMA) are often treated with growth friendly devices such as vertical expandable prosthetic titanium rib(VEPTR) and magnetically controlled growing rods(MCGR) to correct spinal deformity and improve pulmonary function. There is limited data on this topic, and the purpose of this study was to assess the effect of these constructs and the addition of chest wall support (CWS) on spinal deformity, thorax morphology and pulmonary outcomes. METHODS: This is a retrospective analysis of prospectively collected data. We included patients with chest wall deformity and scoliosis secondary to SMA who were treated with growth friendly interventions and had two-year follow-up. Descriptive statistics and univariate analyses were performed. RESULTS: This study included 66 patients (25% MCGR, 73% VEPTR, 2% unknown). Approximately 23% of constructs included CWS. The average Cobb angle improved from 67° (SD: 27°) to 50° (SD: 26°) at 2 years in patients with CWS (p = 0.02), and from 59° (SD: 20°) to 46° (SD: 15°) at 2 years in patients without CWS (p < 0.01). Hemithorax height improved in patients treated with and without CWS (p = 0.01), but hemithorax width only improved in patients with CWS (p = 0.01). One patient with CWS and two patients without CWS required additional respiratory support at 2 years. The rates of postoperative complications were not significantly different in patients treated with and without CWS (p = 0.31). CONCLUSIONS: Growth friendly constructs improve spinal deformity and may be effective in altering the progression toward respiratory failure in patients with SMA. Patients treated with CWS have significant improvements in thorax morphology compared to patients without CWS.

BACKGROUND: Children with spinal muscular atrophy (SMA) sustain a progressive reduction in pulmonary function (PF) related to both muscular weakness and the concomitant effects of spinal deformity on the thorax. Growth-friendly instrumentation is commonly utilized for younger patients with scoliosis and SMA to halt the progression of spinal curvature, but its effect on PF in these patients has not previously been investigated. Using the change in Early Onset Scoliosis 24-Item Questionnaire (EOSQ-24) PF subdomain scores, the authors will investigate whether PF improves in patients with SMA after a growth-friendly intervention. METHODS: This was a multicenter retrospective cohort study from 2 international registries of patients with SMA undergoing spinal deformity surgery from 2005 to 2015. Data collected were age, sex, degree of major coronal curve, type of growth-friendly construct, forced vital capacity (FVC), and EOSQ-24 scores at the patient's preoperative, 1-year postoperative, and 2-year postoperative visits. Differences in EOSQ-24 PF scores and FVC between baseline and postoperative assessment were examined by paired tests. RESULTS: A total of 74 patients were identified (mean age, 7.6±2.3 y, major curve 68.1±22.4 degrees, 51.4% female individuals). The mean EOSQ-24 PF scores improved significantly from 70.6 preoperatively to 83.6 at 1 year (P=0.092) and 86.5 at 2 years postoperatively (P=0.020). The scores in patients with rib-based constructs showed steeper increases at 1-year assessments than those in patients with spine-based constructs. The mean paired FVC value decreased from 63.9% predicted preoperatively, to 57.6% predicted at 1 year postoperatively (P=0.035), and 61.9% predicted preoperatively, to 56.3% predicted at 2 years postoperatively (P=0.178). CONCLUSIONS: Patients with SMA who received growth-friendly instrumentation did experience improvements in PF as measured by EOSQ-24 assessing the caregivers' perception. Given the uncertain reliability of PFTs in this young population, EOSQ-24 is an important tool for measuring improvements in health-related quality of life. LEVEL OF EVIDENCE: Level III-retrospective study.

BACKGROUND: Preoperative and/or intraoperative traction have been proposed as adjunctive methods to limit complications associated with growth-friendly instrumentation for early-onset scoliosis (EOS). By gradually correcting the deformity before instrumentation, traction can, theoretically, allow for better overall correction without the complications associated with the immediate intraoperative correction. The purpose of this multicenter study was to investigate the association between preoperative/intraoperative traction and complications following growth-friendly instrumentation for EOS. METHODS: Patients with EOS who underwent growth rod instrumentation before 2017 were identified from 2 registries. Patients were divided into 2 groups: preoperative traction group versus no preoperative traction group. A subgroup analysis was done to compare intraoperative traction only versus no traction. Data was collected on any postoperative complication from implantation to up to 2 years postimplantation. RESULTS: Of 381 patients identified, 57 (15%) and 69 (18%) patients received preoperative and intraoperative traction, respectively. After adjusting for etiology and degree of kyphosis, there was no evidence to suggest that preoperative halo traction reduced the risk of any complication following surgical intervention. Although not statistically significant, a subgroup analysis of patients with severe curves demonstrated a trend toward a markedly reduced hardware failure rate in patients undergoing preoperative halo traction [preoperative traction: 1 (3.1%) vs. no preoperative traction: 11 (14.7%), P=0.083]. Nonidiopathic, hyperkyphotic patients treated with intraoperative traction were 61% less likely to experience any postoperative complication (P=0.067) and were 74% (P=0.091) less likely to experience an unplanned return to the operating room when compared with patients treated without traction. CONCLUSIONS: This multicenter study with a large sample size provides the best evidence to date of the association between the use of traction and postoperative complications. Our results justify the need for future Level I studies aimed at characterizing the complete benefit and risk profile for the use of traction in surgical intervention for EOS. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Distraction-based techniques allow spinal growth until skeletal maturity while preventing curve progression. METHODS: Two multicenter early-onset scoliosis databases were used to identify patients with idiopathic spine abnormalities treated with traditional growing rods (TGR) or vertically expandable titanium ribs (VEPTR). Patients underwent at least 4 lengthenings and had at least 5-year follow-up. Significance was set at P<0.05. RESULTS: In total, 50 patients treated with TGR and 22 treated with VEPTR were included. Mean (±SD) age at surgery was 5.5 (±2.0) years for the TGR group versus 4.3 (±1.9) years for the VEPTR group (P=0.044); other demographic parameters were similar. VEPTR patients had more procedures (mean 15±4.2) than TGR patients (mean 10±4.0) (P=0.001). Unilateral constructs were present in 18% (4 of 22) of VEPTR and 16% (8 of 50) of TGR patients. Bilateral constructs spanned a mean 2.1 additional surgical levels and exposed patients to 1.6 fewer procedures than unilateral constructs. Curve correction was similar between bilateral and unilateral constructs. TGR patients experienced greater curve correction (50%) than VEPTR patients (27%) (P<0.001) and achieved a greater percentage of thoracic height gain (24%) than VEPTR patients (12%) (P=0.024). At latest follow-up, TGR patients had better maintenance of curve correction, less kyphosis, and 15% greater absolute gain in thoracic height versus VEPTR patients. TGR patients had a lower rate of wound complications (14%) than VEPTR patients (41%) (P=0.011). CONCLUSIONS: In patients with idiopathic early-onset scoliosis, TGRs produced greater initial curve correction, greater thoracic height gains, less kyphosis, and lower incidence of wound complications compared with VEPTR. LEVEL OF EVIDENCE: Level III.
