Abstract
Spinal deformities are considered an important complication of neuromuscular disorders such as spinal muscular atrophy (SMA). SMA patients typically develop progressive early-onset scoliosis, which is associated with increased functional decline, discomfort, and respiratory dysfunction. Over the second decade of the twenty-first century, a lot has changed in terms of the therapeutic options available to people with SMA. Specifically, the use of pharmaceutical agents such as nusinersen (Spinraza), onasemnogene abeparvovec (Zolgensma), and risdiplam (Evrysdi) has dramatically changed the landscape for SMA patients. These medications significantly alter motor- and respiratory functioning, as well as the natural progression of spinal deformities. When evaluating these agents and their impact on the development of scoliosis and motor functioning, it is important to consider the timing of treatment initiation. In patients treated after they had already developed symptoms, a shift of phenotype to a less severe subtype has been observed. This results in a delay in the onset of scoliosis for the less severe SMA types and an increase in early-onset scoliosis for the severe types in patients who would typically not live to develop scoliosis. Patients who receive treatment before they develop symptoms achieve almost normal motor functioning and will likely have a significant decrease in scoliosis prevalence or at least delay its onset.

Abstract
Surgical site infection (SSI) is a devastating complication in patients with neuromuscular scoliosis (NMS) undergoing posterior spinal instrumented fusion (PSIF) for progressive scoliosis. Incisional negative pressure wound therapy (INPWT) has been used in other surgical fields to reduce SSI. Our purpose was to examine the prophylactic use of INPWT after NMS surgery to decrease SSI. At a single institution, 71 consecutive patients with NMS underwent PSIF from 2015 to 2019. Starting in 2017, all patients with NMS received INPWT postoperatively until discharge. Rates of deep SSI were compared between the two cohorts of patients. Additionally, patient demographic and operative factors such as American Society of Anesthesiologists score, number of levels instrumented, need for an anterior spinal release, need for spinal fusion to pelvis, blood loss, operative time, fluoroscopy time, length of stay, and transfusion requirement were analyzed for potential influence on deep SSI. There was no significant difference in deep SSI rates between patients who received INPWT (2 of 41) and those treated with a standard postoperative dressing (2 of 30; P=1.0). Although INPWT theoretically can stabilize the wound environment and prevent deep SSI, our findings do not support this. More research is needed to evaluate the efficacy of INPWT after PSIF for NMS.

Abstract
Pelvic fixation is performed to obtain proper coronal and sagittal alignment when the pelvic obliquity is more than 15º in patients with neuromuscular scoliosis (NMS). Since many NMS patients were wheelchair or bed-ridden status, there has been controversy on the effect of pelvic fixation. Therefore, the purpose of this study is to analyze the effects of pelvic fixation on correction of spinal deformity and quality of life (QoL) in NMS patients. A total of 77 NMS patients who underwent deformity correction were divided into three groups and retrospectively analyzed preoperatively, postoperatively, and at 2-year follow-up: pelvic fixation group (Group A, n = 16), fixed to S1 (Group B, n = 33), and fixed to L5 (Group C, n = 28). The correction rate of scoliosis was 60.0%, 58.0%, and 56.7% in groups A, B, and C, respectively, with no statistical difference (P > 0.05). The correction rate of pelvic obliquity was 61.3%, 42.8%, and 57.5% in respective groups A, B, and C, with no significance (P > 0.05). The correction loss of scoliosis and pelvic obliquity showed no statistical significance between three groups for 2-year follow-up (all Ps > 0.05). There were no significant differences regarding clinical outcomes and postoperative complications among the three groups (all Ps > 0.05). Therefore, pelvic fixation using iliac screws is not substantially influencing radiological and clinical outcomes in the patients with NMS.

Abstract
OBJECTIVE Neuromuscular Scoliosis (NMS) causes severe deformity and operative correction for these patients carries high complication rates. We present a retrospective study comparing a series of consecutive patients who underwent posterior fusion via a single-surgeon (SS) approach with a consecutive series of patients treated via a dual-surgeon (DS) approach. METHODS Patients with NMS who underwent posterior fusion via a SS approach from 2019 to 2022 were analyzed and compared to a series of patients with NMS who underwent posterior fusion via a DS approach. RESULTS In the SS group, the average estimated blood loss (EBL) was 675 mL, average length of stay (LOS) was 6.3 days, average operative time (OT) was 6.5 hours, average packed red blood cell transfusion was 1.5 units, with a complication rate of 30%. The DS group had an average EBL of 400 mL, a LOS of 4.8 days, an OT of 4.75 hours, an average packed red blood cell transfusion of 0.8 units, with a complication rate of 20%. The DS approach was significant for a lower EBL, OT (P < 0.001), and LOS (P < 0.03). CONCLUSIONS This study suggests that for patients with NMS the DS approach decreases OT, EBL, complication rates, and LOS. This further supports that this approach may benefit outcomes in NMS patients.

Abstract
PURPOSE Given the challenges associated with managing progressive scoliosis in patients with cerebral palsy (CP), the purpose of this study was to evaluate deformity correction and HRQOL 5 years post-spinal fusion in CP patients who were skeletally immature at the time of surgical correction. METHODS CP patients who underwent definitive fusion before age 11 with minimum 5-years follow-up from a prospective, multicenter registry were included. Preoperative, initial postoperative, and 5-years radiographic data were collected. Preoperative and 5-years demographic, surgical data, complications, and CPCHILD outcome scores were analyzed. Repeated measures ANOVA with Bonferroni adjustment were used to analyze radiographic measures. Paired t test was utilized to compare outcomes. Significance was set at p = 0.05. RESULTS Twenty patients met inclusion-17 females, 3 males. The mean age was 9 (range 8-10) years. Eight-five percent had spastic CP with GMFCS Level V. Eighteen patients underwent posterior fusion; distal fixation was to the ilium in 80% and to L4-S1 in 20%. Significant correction of the primary curve (p ≤ 0.001) and pelvic obliquity (p ≤ 0.001) were obtained. From initial postoperative to 5-years follow-up there were no significant changes in major curve magnitude (p = 0.638), thoracic kyphosis (p = 0.09) or pelvic obliquity (p = 0.28). CPCHILD personal care, mobility, comfort, and total scores improved from preoperative to 5-years (p < 0.05). One patient needed a reoperation. CONCLUSION Surgical decision making for scoliosis in patients with CP can be difficult given the desire to maximize growth while minimizing adverse events. Performing a definitive fusion is a viable option that achieves good correction which remains stable 5 years postoperatively.

Abstract
Background Systemic inflammatory response syndrome (SIRS) is known to complicate postsurgical intensive care patients. We noticed that roughly half children with cerebral palsy who undergo posterior spinal fusion (PSF) for neuromuscular scoliosis developed SIRS in the intensive care unit. There is a paucity of literature detailing the impact of intraoperative causes of postoperative SIRS and downstream consequences in these patients. Study purpose was to understand the factors associated with SIRS in children who undergo PSF for neuromuscular scoliosis. Methods This retrospective, case control study included children who underwent PSF for neuromuscular scoliosis. Patients with idiopathic scoliosis, osteogenesis imperfecta, and tracheotomy were excluded. Subjects were divided into two study groups based on the diagnosis of SIRS in the intensive care unit. Descriptive statistical analysis was used to identify factors associated with SIRS; a regression analysis was used to further evaluate the independent and significant influence of these factors. Results There was no significant difference in the demographic and other preoperative variables. However, total blood products (ml/kg) administered was significantly higher among the SIRS group compared with the non-SIRS group (54.4±41.0 vs 34.1±21.5 P <0.034). Percent of patients remaining intubated was greater in the SIRS group compared with the non-SIRS group (44.1% vs 7.0%, P < 0.001). The regression model revealed that the odds to develop SIRS in patients who were not extubated were 7.467-fold higher (CI: 1.534-36.347) compared with those who were extubated (p=0.013). Conclusions The incidence of SIRS is significantly higher among the patients who were not extubated at the end of PSF surgery. Further prospective studies are needed to look at the factors that impede the ability to extubate these patients at the end of surgery.

Abstract
BACKGROUND Children with medical complexity are at increased risk of low bone mineral density (BMD) and complications after spinal fusion compared with idiopathic scoliosis patients. Our aim was to compare treatments and outcomes of children with medical complexity undergoing spinal fusion in those who had dual-energy x-ray absorptiometry (DXA) scans versus those who did not in an effort to standardize the workup of these patients before undergoing spinal surgery. METHODS We conducted a retrospective review of patients with low BMD who underwent spinal fusion at a tertiary care pediatric hospital between 2004 and 2016. We consulted with a pediatric endocrinologist to create standard definitions for low BMD to classify each subject. Regardless of DXA status, all patients were given a clinical diagnosis of osteoporosis [at least 2 long bone or 1 vertebral pathologic fracture(s)], osteopenia (stated on radiograph or by the physician), or clinically low bone density belonging to neither category. The last classification was used for patients whose clinicians had documented low bone density not meeting the criteria for osteoporosis or osteopenia. Fifty-nine patients met the criteria, and 314 were excluded for insufficient follow-up and/or not meeting a diagnosis definition. BMD Z -scores compare bone density ascertained by DXA to an age-matched and sex-matched average. Patients who had a DXA scan were also given a DXA diagnosis of low bone density (≤-2 SD), slightly low bone density (-1.0 to -1.9 SD), or neither (>-1.0 SD) based on the lowest BMD Z -score recorded. RESULTS Fifty-nine patients were analyzed. Fifty-four percent had at least 1 DXA scan preoperatively. Eighty-one percent of DXA patients received some form of treatment compared with 52% of non-DXA patients ( P =0.03). CONCLUSIONS Patients referred for DXA scans were more likely to be treated for low BMD, although there is no standardized system in place to determine which patients should get scans. Our research highlights the need to implement clinical protocols to optimize bone health preoperatively. LEVEL OF EVIDENCE Level II-retrospective prognostic study.

Abstract
BACKGROUND Neuromuscular scoliosis is commonly associated with a large pelvic obliquity. Scoliosis in children with cerebral palsy is most commonly managed with posterior spinal instrumentation and fusion. While consensus is reached regarding the proximal starting point of fusion, controversy exists as to whether the distal level of spinal fusion should include the pelvis to correct the pelvic obliquity.
AIM To assess the role of pelvic fusion in posterior spinal instrumentation and fusion, particularly it impact on pelvic obliquity correction, and to assess if the rate of complications differed as a function of pelvic fusion.
METHODS This was a retrospective, cohort study in which we reviewed the medical records of children with cerebral palsy scoliosis treated with posterior instrumentation and fusion at a single institution. Minimum follow-up was six months. Patients were stratified into two groups: Those who were fused to the pelvis and those fused to L4/L5. The major outcomes were complications and radiographic parameters. The former were stratified into major and minor complications, and the latter consisted of preoperative and final Cobb angles, L5-S1 tilt and pelvic obliquity.
RESULTS The study included 47 patients. The correction of the L5 tilt was 60% in patients fused to the pelvis and 67% in patients fused to L4/L5 (P = 0.22). The pelvic obliquity was corrected by 43% and 36% in each group, respectively (P = 0.12). Regarding complications, patients fused to the pelvis had more total complications as compared to the other group (63.0% vs 30%, respectively, P = 0.025). After adjusting for differences in radiographic parameters (lumbar curve, L5 tilt, and pelvic obliquity), these patients had a 79% increased chance of developing complications (Relative risk = 1.79; 95%CI: 1.011-3.41).
CONCLUSION Including the pelvis in the distal level of fusion for cerebral palsy scoliosis places patients at an increased risk of postoperative complications. The added value that pelvic fusion offers in terms of correcting pelvic obliquity is not clear, as these patients had similar percent correction of their pelvic obliquity and L5 tilt compared to children whose fusion was stopped at L4/L5. Therefore, in a select patient population, spinal fusion can be stopped at the distal lumbar levels without adversely affecting the surgical outcomes.

Abstract
BACKGROUND Surgical correction remains the most effective treatment of patients with severe neuromuscular scoliosis (NMS). However, postoperative inpatient clinical care after spinal surgery for NMS patients is highly complex and variable, depending on the provider and/or institution. Our project used a quality improvement methodology to implement a standardized clinical care pathway for NMS patients during their primary spinal surgery, with the global aim of decreasing postoperative hospitalized length of stay (LOS). METHODS A multidisciplinary team developed a postoperative pathway for nonambulatory patients with NMS after their primary, nonstaged corrective spinal surgery. The outcome measure was mean LOS, and the process measure was percentage compliance with the newly implemented NMS pathway. The team used statistical process control charts and measures were evaluated over 3 phases to assess the impact of the interventions over time: pretesting, testing, and sustain. RESULTS The mean LOS decreased from 8.0 to 5.3 days; a statistically significant change based on statistical process control chart rules. Percentage compliance with the NMS pathway improved during the testing and sustain phases, compared with the pretesting phase. LOS variability decreased from pretesting to the combined testing and sustain phases. CONCLUSIONS Using quality improvement methodology, we successfully standardized major components of clinical care for patients with NMS after spinal corrective surgery. Through enhanced care consistency, the mean postoperative LOS decreased by nearly 3 days and decreased LOS variability. Robust multidisciplinary involvement with key stakeholders ensured sustainability of these improvements.

Abstract
BACKGROUND Patients with early-onset scoliosis (EOS) and spasticity may receive treatment with an intrathecal baclofen pump. We assessed how baclofen pumps are associated with the odds of complications and secondary interventions after growth-friendly (GF) spine surgery for EOS and analyzed infectious complications within the pump cohort. METHODS Using a prospectively maintained, international multicenter database, we studied patients with neuromuscular EOS with baclofen pumps who underwent GF spine surgery from 2002 through 2019 (n=25). Baclofen pumps were implanted before GF instrumentation in 18 patients, during in 2 patients, and after in 5 patients. Patients with existing pumps at initial GF spine surgery were matched 1:3 with 54 patients (control group) without pumps according to treatment center, year of surgery, diagnosis, surgery type, and preoperative curve magnitude. Univariate analysis and multivariate logistic regression were performed to compare complications and secondary interventions between the 2 cohorts. RESULTS Patients with baclofen pumps had 4.8 times the odds [95% confidence interval (CI): 1.5-16] of experiencing any complication within 1 year after initial GF spine surgery compared with controls. During mean follow-up of 6.9±4.3 years, they had 4.7 times the odds (95% CI: 1.3-16) of deep surgical site infection and 5.6 times the odds (95% CI: 1.2-26) of spinal rod removal after any complication. Differences in rates of mechanical complication, such as rod migration and breakage, were nonsignificant between the 2 groups. For the 9 patients (50%) with pumps who experienced infections, the most common microorganisms were Staphylococcus aureus (4 patients) and Pseudomonas aeruginosa (2). The pump/catheter was revised or removed, in addition to antibiotic therapy or surgical irrigation and debridement, in 2 patients. CONCLUSIONS Among patients with neuromuscular EOS, those with baclofen pumps are much more likely to experience complications within 1 year after GF spine surgery. They are also more likely to have deep surgical site infections, with S. aureus and P. aeruginosa being the most common causative organisms, and to require spinal rod removal.

Abstract
ABSTRACT Objective: Reveal frontal and sagittal patterns of spinal deformity depending on neuromuscular nosology for surgery and outcome planning. The characteristics of spinal deformity vary according to the pathology. In cerebral palsy, muscular dystrophies, and spinal muscular atrophy, specific features of deformities are poorly written, especially in the sagittal profile. Methods: The evaluation criteria were age, gender of the patients, the volume of blood loss, duration of hospitalization, measurement of the deformity curve, thoracic and lumbar kyphosis (Cobb angle), pelvic obliquity concerning the horizontal line, the percentage of curve correction. Cobb angle was measured preoperatively before hospital discharge (up to 21 days postoperatively) and one year after surgery. Results: The cohort of 71 patients with spinal deformities due to neuromuscular diseases included four groups: muscular dystrophy (MD), spinal muscular atrophy (SMA), Duchenne muscular dystrophy (DMD), and cerebral palsy (CP). The most characteristic deformity in the frontal plane was C-shaped thoracolumbar scoliosis with rotation of the pelvis; rotation of the vertebrae increased according to the magnitude of scoliosis. Lumbar hyperlordosis was common in patients with PD, whereas decreased thoracic kyphosis or even thoracic lordosis occurs more frequently in patients with DMD. Moderate correction of scoliosis was observed in all groups. There was no significant improvement in functional status, according to the FIM. Conclusion: The findings showed that rigid hyperlordosis is the main problem of spinal deformities in neuromuscular patients. Scoliosis and pelvic obliquity can be well corrected in NMS by pedicle screw construction with standard maneuvers and pelvic screw fixation. Level of Evidence IV; Lesser quality prospective study.

Abstract
STUDY DESIGN A prospective study. OBJECTIVE The aim of this study was to report the results of an alternative technique to growing rods (GR) for neuromuscular scoliosis using a minimally invasive fusionless surgery with a minimum of 5 years' follow-up. SUMMARY OF BACKGROUND DATA Conservative treatment is not effective in progressive neuromuscular scoliosis. Early surgery using GR is increasingly advocated to control the deformity while preserving spinal and thoracic growth before arthrodesis. These techniques still provide a high rate of complications. METHODS The technique relies on a bilateral double rod sliding instrumentation anchored proximally by four hooks claws and distally to the pelvis by iliosacral screws through a minimally invasive approach. The clinical and radiological outcomes of 100 consecutive patients with neuromuscular scoliosis who underwent this fusionless surgery with a minimum follow-up of 5 years were reviewed. RESULTS 6.5 ± 0.7 years after initial surgery, six patients were lost of follow-up and 11 died of unrelated raison. Of the 83 remaining patients at latest follow-up, mean Cobb angle was stable to 35.0° which correspond to 61% correction of the initial deformation. Mean pelvic obliquity was 29.6° (0.3°-80.0°) preoperatively and 7.2 (0.2°-23.5°) at latest follow-up. Correction of the hyper kyphosis remained stable. Skeletal maturitywas reached in 42 of 83 patients (50.6%). None of these patients has required spinal fusion. The global complication rate was 31.3%. CONCLUSION The outcomes of this minimally invasive fusionless technique at 5 years follow-up showed a stable correction of spinal deformities and pelvic obliquity over time, with a reduced rate of complication. The arthrodesis was not required for all patients at skeletal maturity. This technique could be a good alternative to arthrodesis for neuromuscular scoliosis.Level of Evidence: 3.

Abstract
ABSTRACT Objectives: To identify the main hospital outcomes of patients undergoing surgical correction of neuromuscular scoliosis and to assess complication rates and achievement of mobility goals after the use of a managed protocol. Methods: This is a longitudinal, retrospective study, with data obtained six months after the application of a protocol in 103 patients of both sexes submitted to surgical correction of neuromuscular scoliosis, at a tertiary level hospital in São Paulo, between June and December 2018 (pre-protocol) and between May and September 2019 (post-protocol). Data from patients who had previously undergone other orthopedic spine surgeries were excluded. In addition to the data for epidemiological characterization of the underlying diseases, the clinical characteristics and complications were analyzed. Results: Of the 103 patients evaluated, there was a predominance of females (53.4%) and a mean age of 14.9 years. The most frequent diagnosis was cerebral palsy, the mean angle of curvature was 75°, and the most frequently observed comorbidities were lung diseases (25%). The protocol was partially adhered to by professionals and after its implementation, there was a significant decrease in pain and the systemic inflammatory response syndrome (SIRS), prevention of immobility and a low rate of infection. Conclusions: The use of a protocol focused on patients undergoing correction of neuromuscular scoliosis led to reduced complications of SIRS and reduced pain; kept the surgical site infection rate low, and prevented short-term immobility.

Abstract
Neuromuscular scoliosis is characterized by rapid progression of curvature during growth and may continue to progress following skeletal maturity. Posterior spinal fusion in patients with cerebral palsy and severe scoliosis results in substantial improvements in health-related quality of life1. Correction of pelvic obliquity can greatly improve sitting balance, reduce pain, and decrease skin breakdown. The sacral alar iliac (SAI) technique has key advantages over prior techniques, including the Galveston and iliac-screw techniques. The SAI technique eliminates the need for subcutaneous muscle dissection over the iliac crest, does not require the use of connectors from the rod to the iliac screw, and decreases the risk of implant prominence2. Description We demonstrate how to perform posterior spinal fusion with SAI pelvic fixation in a patient with cerebral palsy. In correcting the scoliosis, we utilize the segmental 3-dimensional technique, which includes compression, distraction, transverse approximation to 1 rod at a time, and derotation around 2 rods. We also demonstrate SAI pelvic fixation with identification of the screw starting point on the lateral-caudal border of the first sacral foramen and trajectory toward the anterior inferior iliac spine. Alternatives Nonoperative alternatives include bracing, trunk support, contouring of sitting surfaces (such as wheelchairs), and physical therapy to slow curve progression during growth periods and delay the need for surgical treatment3,4. Decision-making is shared with the family following education about the risks and benefits. Families who are satisfied with the function of the child at baseline should not be persuaded into pursuing surgical treatment. Rationale Neuromuscular scoliosis can include difficulty sitting secondary to increased pelvic obliquity, along with poor trunk control and balance. Surgical intervention is considered in patients with curves exceeding approximately 50°, as these curves will often continue to progress even after maturity5. In patients with neuromuscular scoliosis, indications for pelvic fixation include pelvic obliquity of >15°, poor control of the trunk as indicated by lack of independent sitting or standing, and location of the apex of the curve in the lumbar spine. SAI screws are utilized as a low-profile option for pelvic fixation to avoid implant prominence and an increased risk of skin breakdown and infection, which are associated with traditional sacroiliac screws2,6. Expected Outcomes Miyanji et al. reported quality outcomes in patients with cerebral palsy and Gross Motor Function Classification Scores of ≥41. In that study, caregivers completed a validated disease-specific questionnaire grading the health-related quality of life of the patient preoperatively and at 1, 2, and 5 years postoperatively. Complication data were prospectively collected for each patient and preoperative outcome scores were compared at each of the postoperative time points. Survey scores at 1, 2, and 5 years postoperatively were significantly higher compared with baseline preoperative values.Sponseller et al. compared the 2-year postoperative radiographic parameters of 32 pediatric patients who underwent SAI fixation and 27 patients who underwent pelvic fixation with the sacroiliac technique2. Among patients who underwent SAI fixation, the mean correction of pelvic obliquity was 20° ± 11° (70% correction) and the mean Cobb angle 42° ± 25° (67%). Among patients who underwent pelvic fixation with the sacroiliac technique, those values were 10° ± 9° (50%) and 46° ± 16° (60%), respectively. SAI screws provided significantly better pelvic obliquity correction (p = 0.002) but no difference in Cobb correction or complications compared with other traditional techniques. Important Tips Family discussion prior to surgical treatment is paramount.Perform preoperative neurologic examination7.Examine the cranium carefully for a ventriculoperitoneal shunt or prior cranial reconstruction prior to cranial traction.Transcranial neuromonitoring may be useful. Use descending neural motor evoked potentials when no signals from transcranial monitoring are obtained8.Sink the SAI screw until it lines up with the S1 screw. Bury the SAI screw so it is not prominent.Measure rods longer in order to ensure adequate length for compression and distraction in correction of the pelvic obliquity.Use a T-square to verify adequate spinopelvic alignment9.Postoperatively, the use of incisional vacuum-assisted closure can decrease soiling in these patients.

Intravenous Tranexamic Acid Reduces Blood Loss and Transfusion Volume in Scoliosis Surgery for Spinal Muscular Atrophy: Results of a 20-Year Retrospective Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18199959. [PMID: 34639259 PMCID: PMC8507662 DOI: 10.3390/ijerph18199959] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Revised: 09/17/2021] [Accepted: 09/19/2021] [Indexed: 11/16/2022]
Abstract
Intravenous tranexamic acid (TXA) has been administered to reduce intraoperative blood loss in scoliosis surgery. However, the therapeutic effect of TXA on spinal muscular atrophy (SMA) scoliosis surgery is not well demonstrated. Therefore, this study aimed to assess the efficacy of intravenous TXA in SMA scoliosis surgery. From December 1993 to August 2020, 30 SMA patients who underwent scoliosis surgery (posterior fusion with fusion level of thoracic second or third to pelvis) were retrospectively enrolled and divided into the TXA group and non-TXA (control) group, with 15 patients in each group. Survey parameters were the amount of blood loss, blood transfusion, crystalloid transfusion volume, intubation time, and associated pulmonary complications (including pneumonia, pulmonary edema, and pulmonary atelectasis). The TXA group had significantly lesser blood loss than the control group (p = 0.011). Compared with the control group, the TXA group had significantly lower blood transfusion (p < 0.001), crystalloid volume (p = 0.041), and total transfusion volume (p = 0.005). In addition, the TXA group had fewer postoperative pulmonary complications, and patients with pulmonary complications were associated with a higher relative crystalloid volume and relative total transfusion volume (p = 0.003 and 0.022, respectively). In conclusion, TXA can be effective in reducing intraoperative blood loss and crystalloid fluid transfusions during scoliosis surgery in SMA patients, which may aid in reducing postoperative pulmonary complications.

Abstract
BACKGROUND The Japanese Scoliosis Society Morbidity & Mortality Committee performed a longitudinal nationwide complication survey of spinal deformity surgery from 2012 to 2017. The present study aimed to analyze the survey results and report the complication trends of pediatric spinal deformity surgery in Japan. METHODS All Japanese Scoliosis Society members were invited to participate in the survey. Diagnoses were grouped into idiopathic scoliosis, congenital scoliosis, neuromuscular scoliosis, other types of scoliosis, and pediatric kyphosis. Complications were grouped into death, blindness, neurological deficits (motor/sensory), infection, massive bleeding, hematoma, pneumonia, cardiac failure, deep vein thrombosis/pulmonary embolism, gastrointestinal perforation, and instrumentation failure. RESULTS The surveys were performed in 2012, 2014, and 2017. The overall complication rate decreased from 10.7% in 2012 to 8.1% in 2017. In particular, the complication rate in patients with idiopathic scoliosis decreased from 8.8% in 2012 to 4.0% in 2017. The complication rate of patients with neuromuscular scoliosis and kyphosis remained high. The rate of neurological deficits, especially in motor deficits, significantly decreased from 2.0% in 2012 to 0.7% in 2017, and tended to be highest in patients with kyphosis. The rate of massive bleeding was significantly decreased from 3.3% in 2012 to 0.8% in 2017, especially in patients with neuromuscular scoliosis (12.2-4.4%). However, patients with neuromuscular scoliosis had a high rate of postoperative pneumonia (3.7%, 2.6%, and 5.1%, respectively). The rate of instrumentation failure was also high (2.1%, 1.5%, and 2.2%, respectively), especially in patients with early onset idiopathic, congenital and other types of scoliosis. CONCLUSIONS The overall surgical complication rates in pediatric patients decreased due to decreased rates of neurological deficits and massive bleeding, especially in patients with idiopathic scoliosis. However, the complication rates remain high in patients with neuromuscular scoliosis and kyphosis.

Abstract
Scoliosis has a very high prevalence among patients with neuromuscular disease involving the thoracic spine and truncal muscles. Physical examination and radiographs are used to screen for presence of scoliosis and monitor progression. Management includes therapy participation, optimizing equipment and orthotic use, and possible surgical intervention. Unlike idiopathic adolescent scoliosis, curves tend to progress despite orthotic use compliance. Associated pelvic obliquity creates risk for pressure sores and pain. As such, education of caregivers is a key point of optimizing management.

Abstract
INTRODUCTION After discontinuation of growth friendly (GF) surgery for early onset scoliosis, patients undergo spinal fusion or continued observation. This last planned treatment is colloquially called "definitive" treatment, conferring these patients as "graduates" of a growing program. The 5-year radiographic and clinical outcomes of this cohort are unknown. METHODS An international pediatric spine database was queried for patients from a GF program (spine or rib-based) with minimum 5-year follow-up from last planned surgery (GF or spinal fusion). Radiographs and charts were reviewed for main coronal curve angle and maximum kyphosis as well as occurrence of secondary surgery. RESULTS Of 580 graduates, 170 (29%) had minimum 5-year follow-up (37% male). Scoliosis etiology was congenital in 41 (24%), idiopathic 36 (21%), neuromuscular 51 (30%), and syndromic 42 (25%). Index surgery consisted of spine-based growing rods in 122 (71%) and rib-based distraction in 48 (29%). Mean age at index surgery was 6.8 years, and patients underwent an average of 5.4 lengthenings over an average of 4.9 years (range, 6 mo to 11 y). Last planned treatment was at an average age of 11.8 years (range, 7 to 17 years). Last planned treatment consisted of spinal fusion in 114 patients, 47 had growing implants maintained, 9 had implants removed. Average follow-up was 7.3 years (range, 5 to 13 y).When compared from postdefinitive treatment to 2-year follow-up, there was noted progression of the coronal curve angle (46±19 to 51±21 degrees, P=0.046) and kyphosis (48±20 to 57±25 degrees, P=0.03). However, between 2 and 5 years, no further progression occurred in the coronal (51±21 to 53±21 degrees, P=0.26) or sagittal (57±25 to 54±28 degrees, P=0.93) planes. When stratified based on etiology, there was no significant coronal curve progression between 2- and 5-year follow-up. When comparing spinal fusion patients to those who had maintenance of their growing construct, there was also no significant curve progression.Thirty-seven (21%) underwent at least 1 (average, 1.7; range, 1 to 7) revision surgery following graduation, and 15 of 37 (41%) underwent 2 or more revision surgeries. Reason for revision was implant revision (either GF or spinal fusion) in 34 patients, and implant removal in 3. On an average, the first revision was 2.5 years after the definitive treatment plan (range, 0.02 to 7.4 y). In total, 15 of 37 (41%) revisions occurred over 2 years following the final decision for treatment plan, and 7 of 37 (19%) occurred 5 or more years after the definitive treatment.Patients who underwent spinal fusion as a definitive treatment strategy were more likely to undergo revision surgery (27%) than patients who had their GF implants maintained (11%) (P=0.04). CONCLUSIONS Five years following "graduation" from growing surgery for early onset scoliosis, there is progression of curve magnitude in both the coronal and sagittal planes up to 2 years, with no further progression at 5 years. A total of 21% of patients undergo at least 1 revision surgery, and average time to revision surgery is over 2 years from last planned surgery. Risk of revision surgery was higher in patients who underwent a spinal fusion as their definitive treatment strategy. LEVEL EVIDENCE Level III-retrospective comparative. TYPE OF EVIDENCE Therapeutic.

Abstract
STUDY DESIGN Single-center retrospective cohort analysis. OBJECTIVE The aim of this study was to evaluate risk factors associated with the development of proximal junctional kyphosis (PJK) in pediatric neuromuscular scoliosis (NMS). SUMMARY OF BACKGROUND DATA PJK is a common cause of reoperation in adult deformity but has been less well reported in pediatric NMS. METHODS Sixty consecutive pediatric patients underwent spinal fusion for NMS with a minimum 2-year follow-up. PJK was defined as >10° increase between the inferior end plate of the upper instrumented vertebra (UIV) and the superior end plate of the vertebra two segments above. Regression analyses as well as binary correlational models and Student t tests were employed for further statistical analysis assessing variables of primary and compensatory curve magnitudes, thoracic kyphosis, proximal kyphosis, lumbar lordosis, pelvic obliquity, shoulder imbalance, Risser classification, and sagittal profile. RESULTS The present cohort consisted of 29 boys and 31 girls with a mean age at surgery of 14 ± 2.7 years. The most prevalent diagnoses were spinal cord injury (23%) and cerebral palsy (20%). Analysis reflected an overall radiographic PJK rate of 27% (n = 16) and a proximal junctional failure rate of 7% (n = 4). No significant association was identified with previously suggested risk factors such as extent of rostral fixation (P = 0.750), rod metal type (P = 0.776), laminar hooks (P = 0.654), implant density (P = 0.386), nonambulatory functional status (P = 0.254), or pelvic fixation (P = 0.746). Significant risk factors for development of PJK included perioperative use of halo gravity traction (38%, P = 0.029), greater postoperative C2 sagittal translation (P = 0.030), decreased proximal kyphosis preoperatively (P = 0.002), and loss of correction of primary curve magnitude at follow-up (P = 0.047). Increase in lumbar lordosis from post-op to last follow-up trended toward significance (P = 0.055). CONCLUSION Twenty-seven percent of patients with NMS developed PJK, and 7% had revision surgery. Those treated with halo gravity traction or with greater postoperative C2 sagittal translation, loss of primary curve correction, and smaller preoperative proximal kyphosis had the greatest risk of developing PJK.Level of Evidence: 4.

"Pediatric spinal deformities may be associated with pulmonary complications in a patient's lifetime. A review of the diagnosis of spinal abnormalities includes classifications of scoliosis and kyphosis, correlating physical examination findings and radiographic interpretation. The natural history of untreated spine deformities is reviewed along with the associated altered pulmonary compromise. Treatment options for children affected by spinal deformities are discussed, including the relative indications, the efficacy, pros and cons of different treatment options, along with the evidence to support these. This overview of spine deformities includes research outcomes to support the care of these pediatric patients."

Abstract
Cerebral palsy is the most common cause of childhood motor disability, affecting 2 to 3/1000 children worldwide. Clinical abnormalities in tone, posture, and movement are the result of brain dysgenesis or injury early in life, and impairment varies in type, distribution, and in severity. The underlying brain disorder may also lead to other associated neurologic and systemic impairments. Variability in functional impairments, which can change during development, necessitates an individualized treatment plan. Treatment options are primarily symptomatic and directed toward optimizing independence, function, and/or ease of care-while limiting side effects. New promising disease-preventing and modifying treatments are emerging.

Abstract
STUDY DESIGN This is a retrospective cohort study via a single surgeon, two-hospital database. OBJECTIVE PSF in NMS patients is a high-risk surgery, with rates of SSI up to 24%. There is conflicting evidence in the literature regarding a possible association between low preoperative nutritional lab values and heightened risk of SSI after PSF. A retrospective analysis of a 20-year cohort of 111 pediatric neuromuscular scoliosis (NMS) patients that underwent posterior spinal fusion (PSF) with instrumentation was performed. Overall, seven patients (6.3%) developed a postoperative surgical site infection (SSI). With the possible exception of transferrin, low preoperative lab values (prealbumin, Hgb/Hct, WBC, TLC, total protein, albumin) were not associated with SSI. These findings question the utility of the current methodology of preoperative laboratory evaluation in identifying patients at elevated risk for SSI following PSF. METHODS A single-surgeon, two-hospital database was reviewed to identify all patients who underwent PSF for NMS. Diagnoses included cerebral palsy (n = 82), myelomeningocele (n = 13), spinal muscular atrophy (n = 4), and other (n = 12). Medical records for 117 patients were examined; 6 were excluded due to missing lab values. SSI was defined as an infection necessitating a return to the operating room for irrigation and debridement of the surgical site. Demographic information, preoperative lab values, spinal deformity magnitude, and surgical procedure data were recorded. RESULTS There were 50 males and 61 females with a mean age of 14 years and 2.5 months (8-20 years). Seven patients (6.3%) experienced postoperative SSI. SSI rate for PSF to pelvis was 7.7% vs. PSF to lumbar spine, 3.0% (NS; p = 0.672). Length of PSF was not statistically associated with SSI (p = 0.172). SSI due to gram positives and polymicrobial gram negatives occurred with equal incidence. Preoperative lab values of transferrin, prealbumin, albumin, WBC count, total lymphocyte count, and total protein were not associated with SSI. Patients with postoperative SSI had higher mean Hct compared to controls (p = 0.041). While 40.6% of controls had low Hgb (< 13.8 g/dl), all patients who developed SSI had Hgb within the normal range (p = 0.043). Similarly, while 37.6% of controls had low Hct (< 40.7%), all patients who developed SSI had Hct within the normal range (p = 0.05). CONCLUSION Low preoperative nutritional labs, Hgb/Hct, and TLC values were not found to be associated with an increased incidence of SSI in this analysis. These findings question the utility of preoperative lab values in identifying "at-risk" populations for SSI after PSF for NMS. LEVEL OF EVIDENCE IV Therapeutic.

Abstract
Objective The aim of the present study is to identify the incidence, predisposing factors and prognostic impact of blood loss in patients with neuromuscular scoliosis submitted to corrective surgery. Methods Retrospective cohort study, including pediatric patients diagnosed with neuromuscular scoliosis undergoing instrumentation and posterior vertebral fusion in a university hospital. Patient characteristics were collected from the hospital information system. Results A total of 39 patients were included in the study. The intraoperative blood losses were 962 ml, representing a loss of 35.63% of the blood volume. In 20 cases, there was a massive blood loss (> 30%) and only 7 patients did not need a transfusion. The group of patients with massive blood loss had a slightly higher age (13.75 versus 13.53 years old), a lower body mass index (BMI) percentile (25 versus 50), and for each decrease of 0.38 in the BMI, intraoperative blood losses increased 1% ( p < 0.05). The value of preoperative albumin had influence on the percentage of blood loss, and for each decrease of 0.4 of albumin, blood loss increased 1% ( p < 0.05). Conclusions The factors that most contributed to the differences in blood loss were age, BMI, and preoperative albumin value. There was no significant association between Cobb angle, number of fusion levels and duration of surgery. We can conclude that these patients would benefit from preoperative nutritional control.

Abstract
PURPOSE The purpose of this study is to evaluate whether patients with high-tone neuromuscular early-onset scoliosis have different surgical outcome and complication rate, when compared to patients with low-tone neuromuscular early-onset scoliosis treated with a rib-to-pelvis rib-based dual growing system. METHODS This is a retrospective cohort study of 67 neuromuscular early-onset scoliosis patients, collected from a multicenter database, treated with a rib-to-pelvis rib-based dual growing system. All patients were divided into two groups: high tone and low tone. Pre-, intra- and postoperative data were compared between both groups. Complications were reported by a standardized system. RESULTS Twenty-six high-tone and 41 low-tone patients were found homogeneous regarding gender, age at surgery, weight, height, estimated blood loss and surgery time. High-tone group (19/26 = 73.1%) experiences more postoperative complications than low-tone group (22/41 = 53.7%). Most common complications were infection, device migration, death and hardware failure. Permanent abandonment of rib-based growing technique and device removal was required in 21% of high-tone patients (P < 0.001). None of the low-tone patients required abandonment. CONCLUSION High-tone patients had more complications than those with low tone in management of neuromuscular early-onset scoliosis treated with a rib-to-pelvis rib-based dual growing system. A different surgical approach may be required to treat the high-tone neuromuscular early-onset scoliosis.

Abstract
OBJECTIVES To convey advice from families whose children recently underwent spinal fusion to families whose children are under consideration for initial spinal fusion for neuromuscular scoliosis and to providers who counsel families on this decision. STUDY DESIGN We interviewed 18 families of children who underwent spinal fusion between August 2017 and January 2019 at a freestanding children's hospital. We conducted phone interviews a median of 65 (IQR 51-77) days after surgery. We audio recorded, transcribed, and coded (line-by-line) interviews using grounded theory by 2 independent reviewers, and discussed among investigators to induce themes associated with surgical decision making and preparation. RESULTS Six themes emerged about decision making and preparation for spinal fusion: (1) simplify risks and benefits; it is easy to get lost in the details; (2) families prolonging the decision whether or not to pursue spinal fusion surgery may not benefit the child; (3) anticipate anxiety and fear when making a decision about spinal fusion; (4) realize that your child might experience a large amount of pain; (5) anticipate a long recovery and healing process after spinal fusion; and (6) be engaged and advocate for your child throughout the perioperative spinal fusion process. CONCLUSIONS Parents of children who had recently undergone spinal fusion had strong perceptions about what information to convey to families considering surgery, which may improve communication between future parents and physicians. Further investigation is needed to assess how best to incorporate the wisdom and experiences of parent peers into shared decision making and preparation for spinal fusion in children with neuromuscular scoliosis.

Abstract
This study describes a new procedure for a safer and easier access for the intrathecal injection of the recently approved nusinersen therapy in spinal muscular atrophy. This therapy changed the natural history of the disease, but, to date, scoliosis surgery was an excluding criteria for nusinersen therapy. The bone mass, due to the posterior spinal fusion of the scoliosis surgery, prevents the needle for the nusinersen administration from intervertebral access. This is a single-center, single-surgeon case series descriptive study. A laminotomy at the L3-L4 level was performed to provide safer access for the intrathecal injection. The procedure was carried out during the scoliosis surgery in patients who underwent posterior spinal fusion (PSF) after the nusinersen therapy was introduced, whereas for those who underwent PSF earlier, a second procedure was necessary to perform a laminotomy. A fat grafting was used to prevent bone overgrowth in the laminotomy. Markers were applied as radiographic references for the intrathecal injection. Five patients were enrolled, four females and one male. The mean age of the patients was 11 years. Three patients underwent PSF before the introduction of the nusinersen therapy. Two patients underwent PSF after the nusinersen therapy was available. All of them underwent a laminotomy with a fat grafting at the L3-L4 laminotomy level and received nusinersen therapy without complications. The procedure described is simple and effective in providing safe intrathecal access to make these patients eligible for such important therapy.

Abstract
The aim of this study is to evaluate the results of the modified Kostuik transilial bar technique for neuromuscular scoliosis (NS). We reviewed the records of 21 patients treated for NS with this instrumentation. There were 14 females and seven males, with an average age of 15.6 years (range: 9-21 years). We determined patients' demographics, correction ratio of both curve and pelvic obliquity, loss of correction, screw loosening at first sacral vertebra, and clinical outcomes. Mean follow-up was 56 months (range: 34-96 months). There were no reoperations, no screw breakage, and no significant loss of correction. The mean preoperative coronal Cobb angle was 71.4°±8.7°, the initial postoperative measurements had a mean Cobb angle of 19.2°±7.2°, and at the last follow-up, the mean Cobb angle was 23.6°±6.9° (P<0.001). Pelvic obliquity decreased from 27.7°±12.4° to 9.1°±5.3° at follow-up and to 11.9°±6.3° at the last follow-up (P<0.001). The preoperative pelvic obliquity angle was significantly higher at the patients with screw loosening (P=0.016). There was one established as well as one possible pseudoarthrosis in our patients. The new technique does appear to possibly become an alternative to conventional lumbosacral fixation techniques. Integration of the bar with pipe-type connector onto the long spinal instrumentation with oblique connectors can prevent the most unenviable complications such as wide exposure, hardware prominence, reoperation, and pseudoarthrosis.

Abstract
PURPOSE OF REVIEW Spinal deformity is a common issue in pediatric patients with an underlying neurological diagnosis or syndrome. Management of neuromuscular scoliosis (NMS) is a major part of the orthopedic care of such patients, as the deformity is often progressive, and may affect gait, seating and positioning. In addition, untreated large spinal deformities may be associated with pain and/or cardiopulmonary issues over time. RECENT FINDINGS Recent changes in medical management of the underlying disease process appears to alter the natural history of certain neuromuscular conditions, and in the case of patients with Duchenne's muscular dystrophy significantly diminish the incidence of spinal deformity. In the most common diagnosis associated with NMS, cerebral palsy, there is evidence that despite a high complication rate, surgical management of spinal deformity is associated with measurable improvements in validated health-related quality-of-life measures. Spinal deformity is a common finding in patients with neurological diagnoses. It is important for those involved in the care of these patients to understand the natural history of NMS, as well as the potential risks and benefits to the patient and caregivers, of surgical and non-surgical interventions.

Abstract
STUDY DESIGN Retrospective review of a prospective cohort. OBJECTIVE To identify patient and surgical factors that alter the length of postoperative intensive care unit (ICU) stays after spinal fusion/instrumentation in patients with neuromuscular scoliosis secondary to cerebral palsy (CP). SUMMARY OF BACKGROUND DATA High perioperative complication rates in patients with CP contribute to the practice of utilizing the ICU postoperatively for monitoring. However, this is costly and little is known regarding which patients truly need this increased acuity of care. METHODS A prospective, multicenter database was queried for patients with CP who underwent spinal fusion and instrumentation. Patients with an ICU length of stay (LOS) ≤1 day were assumed to not have required postoperative ICU admission. Demographic and surgical characteristics were compared between those with ICU LOS of ≤1 day versus >1 day. A classification and regression tree (CART) analysis was utilized to create a decision algorithm for postoperative ICU admission. RESULTS Three hundred twenty-four patients were identified with a mean ICU LOS of 4.7 days (range 0-47). Sixty-eight patients (21%) had an ICU LOS ≤1 day and 256 patients (79%) had an ICU LOS >1 day. CART analysis demonstrated that the institution where the surgery was performed was the primary predictor with two groups: sites that almost routinely had ICU stay >1 day (92%) and those that were split (50.5% >1 day). In the latter group, an operative time greater than 4 hours was a risk factor for a longer ICU stay. CONCLUSION Because of their heterogeneous makeup, CP patients should be evaluated individually and their postoperative disposition should not be based on institutional tradition but instead on objective surgical factors. For those patients with surgical times less than 4 hours, discussions should be held regarding the safety of a postoperative disposition to a regular floor. LEVEL OF EVIDENCE Level III.

Abstract
OBJECTIVE The objective of this study is to identify preoperative laboratory values and patient factors that are associated with postoperative respiratory complications in pediatric neuromuscular scoliosis (NMS) populations undergoing posterior spinal fusion (PSF) with instrumentation. SUMMARY OF BACKGROUND DATA PSF in NMS patients are high-risk surgeries. Respiratory complications are the most common postoperative event, with rates up to 28.2% following surgery. METHODS A single-surgeon, two-hospital pediatric spine surgery database was reviewed to identify all patients who underwent PSF for NMS. Diagnoses included cerebral palsy (n=83), myelomeningocele (n=13), spinal muscular atrophy (n=4), and other (n=11). This study defined respiratory complications as postoperative pneumonia, pleural effusion, pneumothorax, need for reintubation, respiratory status requiring a return to the pediatric intensive care unit (PICU), or prolonged (>4-day) need for mechanical ventilation. Preoperative laboratory values for transferrin, prealbumin, hemoglobin/hematocrit, total protein, albumin, and total lymphocyte count were collected. RESULTS There were 50 males and 61 females with a mean age of 14 years 2.5 months (8-20 years). Seventeen patients (15.3%) experienced postoperative respiratory complications. On univariate analysis, any history of pneumonia, the presence of gastrostomy tube, and low transferrin levels were associated with postoperative respiratory complications, and a strong trend (p=.06) was observed for tracheostomy. On multivariate analysis, the presence of gastrostomy tube and history of pneumonia remained as clinically significant predictors of postoperative respiratory complications. CONCLUSION Pediatric NMS patients undergoing PSF that have history of pneumonia or gastrostomy tube present at time of surgery are at increased risk for postoperative respiratory complications. The univariate associations of tracheostomy presence and low transferrin levels with postoperative respiratory complications deserve further examination. LEVEL OF EVIDENCE Level II.

Abstract
OBJECTIVE This study aims to elucidate surgical risk factors in neuromuscular scoliosis (NMS) with respect to wound site infection after spinal fusion. METHODS A retrospective review was performed of all patients treated surgically for NMS between January 2008 and December 2016 (minimum 6 months' follow-up). A sub-cohort of 60 patients with minimum 2 years of follow-up data was also analyzed. RESULTS In 102 patients (53 boys and 49 girls), the mean age at surgery was 14.0 years (SD ±2.7). Mean follow-up was 2.53 years (±1.66), and mean time to presentation of infection was 2.14 months (±4.95). The overall perioperative complication rate was 26.5%, with 14.7% of patients developing deep wound infection. Gram-negative bacteria were responsible for 60% of infections; 20% were Gram positive, and 20% involved both types. Pulmonary comorbidities (p = 0.007), pre- to postoperative increase in weight (p = 0.010), exaggerated lumbar lordosis at follow-up (p = 0.008), history of seizures (p = 0.046), previous myelomeningocele repair (p = 0.046), and previous operations (p = 0.013) were significant risk factors for infection. CONCLUSION Our data suggest that in the pediatric population treated surgically for NMS, wound infection is strongly associated with postoperative increase in body weight, residual lumbar lordosis, pulmonary comorbidity, history of myelomeningocele repair, seizures, and previous operations.

Abstract
INTRODUCTION Duchenne muscular dystrophy (DMD) is a devastating, progressive neuromuscular disorder for which there is no cure. As the dystrophin gene is located on the X chromosome, DMD occurs predominately in males. DMD is caused by a lack of functional dystrophin protein resulting from mutations in the 2.2-Mb DMD gene, whichdisrupts the reading frame. Care considerations for DMD advocate a coordinated, multidisciplinary approach to the management of DMD in order to optimize management of the primary manifestations of DMD as well as any secondary complications that may arise. METHODS This review provides an overview of the multidisciplinary clinical management of DMD with regard to the respiratory, cardiology, orthopedic, and nutritional needs of patients with DMD. Recent advances in novel disease-modifying treatments for DMD are also discussed with specific reference to exon skipping and suppression of premature stop codons as promising genetic therapies. RESULTS The combination of multidisciplinary clinical management alongside novel gene therapiesoffers physicians a powerful armamentarium for the treatment of DMD.

Abstract
OBJECTIVE High rates of perioperative complications are associated with deformity correction in neuromuscular scoliosis. The current study aimed to evaluate complications associated with surgical correction of neuromuscular scoliosis and to characterize potential risk factors. METHODS Data were retrospectively collected from a single-center cohort of 102 consecutive patients who underwent spinal fusions for neuromuscular scoliosis between January 2008 and December 2016 and who had a minimum of 6 months of follow-up. A subgroup analysis was performed on data from patients who had at least 2 years of follow-up. Univariate and multivariate regression analyses, as well as binary correlational models and Student t-tests, were employed for further statistical analysis. RESULTS The present cohort had 53 boys and 49 girls with a mean age at surgery of 14.0 years (± 2.7 SD, range 7.5-19.5 years). The most prevalent diagnoses were cerebral palsy (26.5%), spinal cord injury (24.5%), and neurofibromatosis (10.8%). Analysis reflected an overall perioperative complication rate of 27% (37 complications in 27 patients), 81.1% of which constituted major complications (n = 30) compared to a rate of 18.9% for minor complications (n = 7). Complications were predicted by nonambulatory status (p = 0.037), increased intraoperative blood loss (p = 0.012), increased intraoperative time (p = 0.046), greater pelvic obliquity at follow-up (p = 0.028), and greater magnitude of sagittal profile at follow-up (p = 0.048). Pulmonary comorbidity (p = 0.001), previous operations (p = 0.013), history of seizures (p = 0.046), diagnosis of myelomeningocele (p = 0.046), increase in weight postoperatively (p < 0.005), and increased lumbar lordosis at follow-up (p = 0.015) were identified as risk factors for perioperative infection. CONCLUSIONS These results suggest that in neuromuscular scoliosis, patients with preexisting pulmonary compromise and greater intraoperative blood loss have the greatest risk of experiencing a major perioperative complication following surgical deformity correction.

Abstract
Evaluation of pediatric spinal deformity requires knowledge of special orthopaedic testing and radiographic interpretation. The determination of recommendations for treatment of spinal abnormalities in children can be challenging and at times complex, as treatment options are dependent upon a variety of factors. The etiology of scoliosis or kyphosis, presence or absence of vertebral anomalies, symptoms, magnitude of the curve, physiologic/skeletal age, and evidence of and risk of progression all require consideration and play a role in the shared decision-making process. This article provides an overview of relevant information and includes research outcomes to support the care of pediatric patients with spinal deformities. [Pediatr Ann. 2017;46(12):e472-e480.].

Abstract
PURPOSE Scoliosis with pelvic obliquity (PO) could be investigated with the EOS-CHAIR protocol as the most common deformity especially in patients with trunk hypotonia and quadriplegia. However, the intra-observer and inter-observer reliability of various angles assessing PO was not investigated with this new imaging protocol. METHODS A retrospective cohort of 36 EOS frontal full-spine acquisitions made in sitting position was used. The sacroiliac pelvic obliquity angle, iliac crest pelvic obliquity angle, and ischiatic pelvic obliquity angle were assessed in an intra-observer and inter-observer study. RESULTS The use of the EOS-CHAIR protocol was implemented satisfactory with a high acceptance rate by all caregivers and patients and their families. Intra-observer and inter-observer reliability was excellent for the three tested angular measurements. DISCUSSION As for idiopathic scoliosis, we postulate the EOS system as being superior to standard radiographs to assess 3D spinal deformities in neuromuscular conditions. The EOS-CHAIR protocol improves preoperative comprehension of the lumbosacral junction anatomy in patients with poor standing or sitting postures. Our results show a very high reliability of three different angular measurements of the frontal pelvic obliquity in sitting position. Then it is possible to use one of these three angles as well as the others to assess frontal pelvic obliquity in neuromuscular patients. This frontal pelvic obliquity protocol in sitting position with the EOS-CHAIR is a validated measurement technique that needs to be used now to measure PO as a critical parameter of the global trunk balance in neuromuscular patients.

Abstract
OBJECTIVE The objective of this study was to determine if the recent changes in technology, surgical techniques, and surgical literature have influenced practice trends in spinal fusion surgery for pediatric neuromuscular scoliosis (NMS). In this study the authors analyzed recent trends in the surgical management of NMS and investigated the effect of various patient and surgical factors on in-hospital complications, outcomes, and costs, using the Nationwide Inpatient Sample (NIS) database. METHODS The NIS was queried from 2002 to 2011 using International Classification of Diseases, Ninth Edition, Clinical Modification codes to identify pediatric cases (age < 18 years) of spinal fusion for NMS. Several patient, surgical, and short-term outcome factors were included in the analyses. Trend analyses of these factors were conducted. Both univariate and multivariable analyses were used to determine the effect of the various patient and surgical factors on short-term outcomes. RESULTS Between 2002 and 2011, a total of 2154 NMS fusion cases were identified, and the volume of spinal fusion procedures increased 93% from 148 in 2002 to 286 in 2011 (p < 0.0001). The mean patient age was 12.8 ± 3.10 years, and 45.6% of the study population was female. The overall complication rate was 40.1% and the respiratory complication rate was 28.2%. From 2002 to 2011, upward trends (p < 0.0001) were demonstrated in Medicaid insurance status (36.5% to 52.8%), presence of ≥ 1 comorbidity (40.2% to 52.1%), and blood transfusions (25.2% to 57.3%). Utilization of posterior-only fusions (PSFs) increased from 66.2% to 90.2% (p < 0.0001) while combined anterior release/fusions and PSF (AR/PSF) decreased from 33.8% to 9.8% (< 0.0001). Intraoperative neurophysiological monitoring (IONM) underwent increasing utilization from 2009 to 2011 (15.5% to 20.3%, p < 0.0001). The use/harvest of autograft underwent a significant upward trend between 2002 and 2011 (31.3% to 59.8%, p < 0.0001). In univariate analysis, IONM use was associated with decreased complications (40.7% to 33.1%, p = 0.049) and length of stay (LOS; 9.21 to 6.70 days, p <0.0001). Inflation-adjusted mean hospital costs increased nearly 75% from 2002 to 2011 ($36,805 to $65,244, p < 0.0001). In the multivariable analysis, nonwhite race, highest quartile of median household income, greater preexisting comorbidity, long-segment fusions, and use of blood transfusions were found to increase the likelihood of complication occurrence (all p < 0.05). In further multivariable analysis, independent predictors of prolonged LOS included older age, increased preexisting comorbidity, the AR/PSF approach, and long-segment fusions (all p < 0.05). Lastly, the likelihood of increased hospital costs (at or above the 90th percentile for LOS, 14 days) was increased by older age, female sex, Medicaid insurance status, highest quartile of median household income, AR/PSF approach, long-segment fusion, and blood transfusion (all p < 0.05). In multivariable analysis, the use of autograft was associated with a lower likelihood of complication occurrence and prolonged LOS (both p < 0.05). CONCLUSIONS Increasing use of IONM and posterior-only approaches may combat the high complication rates in NMS. The trends of increasing comorbidities, blood transfusions, and total costs in spinal fusion surgery for pediatric NMS may indicate an increasingly aggressive approach to these cases.
