Elmeshneb MA, Hassanin MA, Elnady B, Sleem A, Le GT, Patel MS, Quraishi NA. Surgical complications in neuromuscular scoliosis surgery: systematic review and meta-analysis of the last ten years. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2024:10.1007/s00586-024-08338-y. [PMID: 38869648 DOI: 10.1007/s00586-024-08338-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 05/01/2024] [Accepted: 05/26/2024] [Indexed: 06/14/2024]
Abstract
PURPOSE Surgical correction of neuromuscular scoliosis is often a challenging and extensive procedure. Due to this complexity and the high disease burden that these patients carry, per and post-operative complications are not uncommon. The purpose of this study was to systematically review and describe the pooled rates of postoperative complications and analyze risk factors for complications in neuromuscular scoliosis surgery described in the literature in the last ten years. METHODS A systematic review of the English literature across multiple databases was conducted using search criteria (neuromuscular scoliosis AND complications) and using PRISMA guidelines (Jan 2012-July 2022). Studies with less than 30 patients and follow-up of < 2 years were excluded. Data extraction and meta-analysis were performed using random mode effect. Statistical analysis was conducted using OpenMeta software. Meta-regression analysis was used to detect risk factors (surgical approach, intraoperative time, intraoperative blood loss, preoperative Cobb angle and patient diagnosis) associated with each complication group. Confidence interval (CI) was set at 95%. RESULTS Twenty-two studies met the inclusion criteria involving 2155 patients. The level of evidence among studies were III (9) and IV (13). The most common primary diagnosis was cerebral palsy (43%) followed by Duchenne muscle dystrophy (20%), myelomeningocele (7.4%), spinal muscle atrophy (7.1%), Rett syndrome (< 2%) and combined other pathologies (20.2%). The pooled incidence rate of wound complications was the highest, amongst all complications, at 13.3% (CI 10.838 to 16.861); closely followed by respiratory complications (11.8%;CI 5.7 to 19.7). Implant failure occurred in 7.1% cases (CI 6.418 to 11.465), gastrointestinal complications was 5.2%; CI 2.4 to 8), pseudarthrosis in (4.6%;CI 2.2 to 6.9) and neurological deficit in 2.9% (CI 1.989 to 6.086). The pooled rate of revision surgery was (9.6%; CI 6.2 to 12.9). Heterogeneity was assessed using I2 test which results were moderately heterogeneous. Meta-regression analysis revealed that the diagnosis of myelomeningocele or Duchenne muscle dystrophy or spinal muscle atrophy were strongly associated with wound and respiratory complications (p = 0.007 and p = 0.005, respectively). CONCLUSION Wound-related (13.3%) and respiratory complications (11.8%) remain the most common complications among studies after corrective surgery for neuromuscular scoliosis. Both are significantly associated with Duchenne muscle dystrophy, spinal muscle atrophy and myelomeningocele.

Long-term reoperation rates following spinal fusion for neuromuscular scoliosis in nonambulatory patients with cerebral palsy. Spine Deform 2024:10.1007/s43390-024-00878-z. [PMID: 38683283 DOI: 10.1007/s43390-024-00878-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Accepted: 04/05/2024] [Indexed: 05/01/2024]
Abstract
PURPOSE To describe the incidence of reoperation and factors contributing to surgical revision within a minimum of 10 years after spinal fusion for scoliosis in patients with nonambulatory cerebral palsy (CP). METHODS We conducted a retrospective review of consecutive nonambulatory patients with CP who underwent primary spinal fusion at a single specialty care center with a minimum of 10 years from their index surgery (surgery dates 2001-2011). Causes of reoperation were classified as implant failure/pseudoarthrosis, surgical site infection (SSI), proximal junctional kyphosis, prominent/symptomatic implants, and implant removal. Reoperation rates with 95% confidence intervals were calculated for each time interval, and an actuarial survival curve was generated. RESULTS 144 patients met inclusion criteria (mean age = 14.3 ± 2.6 years, 62.5% male); 85.4% had 5 years follow-up data; and 66.0% had 10 years follow-up data. Estimates from the actuarial analysis suggest that 14.9% (95% CI: 10.0-22.0) underwent reoperation by 5 years postsurgery, and 21.7% (95% CI: 15.4-30.1) underwent reoperation by 10 years postsurgery. The most common causes for reoperation were implant failure/pseudoarthrosis, SSI, and prominent/symptomatic implants. CONCLUSIONS To our knowledge, this study is the largest long-term follow-up of nonambulatory patients with CP and neuromuscular scoliosis who underwent spinal fusion. Approximately 22% of these patients required reoperation 10 years after their index surgery, primarily due to implant failure/pseudoarthrosis, SSI, and prominent/symptomatic implants. Complications and reoperations continued throughout the 10 years period after index surgery, reinforcing the need for long-term follow-up as these patients transition into adulthood.

Tranexamic Acid in Hip Reconstructions in Children with Cerebral Palsy: A Double-Blind Randomized Controlled Clinical Trial. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1931.

Abstract
Surgical treatment is indicated for hip dislocation in patients with cerebral palsy (CP), but it requires care due to the state of nutrition and associated clinical comorbidities. The use of resources that minimize blood loss and the need for blood transfusions are essential to avoid complications. Tranexamic acid (TXA) has been highlighted for orthopedic surgeries to control intraoperative bleeding; however, there is a lack of large studies for its use in hip surgeries in patients with CP. This study aims to evaluate the efficacy and safety of tranexamic acid to reduce bleeding in pediatric patients with cerebral palsy undergoing surgical treatment for hip instability. A sample of 31 patients with CP who underwent surgical treatment for hip dislocation (hip adductor stretching, varization osteotomy of the proximal femur and acetabuloplasty using the Dega technique) was randomly divided into groups: control (n = 10) and TXA (n = 21). Preoperative and 24 h hemoglobin concentrations, the length of hospital stay (LHS), and intraoperative bleeding (IB) were analyzed. TXA significantly reduced the IB (p = 0.02). The variance in hemoglobin concentration was lower for the TXA group, but without statistical significance (p = 0.06). There was no difference in LHS. Also, no statistical difference was observed for the number of transfusions (p = 0.08). The findings provide evidence of the effectiveness of TXA in decreasing intraoperative bleeding and its safety for use in pediatric patients with cerebral palsy.

Abstract
PURPOSE Intra-operative traction (IOT) has emerged as new modality for improving correction rates in scoliosis since it has the potential to reduce operative time and blood loss in neuromuscular scoliosis (NMS). The aim of this study is to describe the effects of IOT in deformity correction in NMS. METHODS The search was conducted in online electronic databases following the PRISMA guidelines. This review included studies on NMS which have described usage of IOT in deformity correction. RESULTS Eight studies were included in analysis and review. There was low-to-moderate heterogeneity across the studies (I2 - 42.4 to 93.9%). All the studies used cranio-femoral traction for IOT. The final Cobb's angle in coronal plane was significantly lower in the traction group as compared to the non-traction group (SMD - 0.36 95% CI - 0.71 to 0). There was a trend towards better outcomes in final obliquity (SMD - 0.78 95% CI - 1.64 to 0.09), operative time (SMD - 1.09 95% CI - 2.25 to 0.08) and blood loss (SMD - 0.86 95% CI significantly lower in the traction group as 2.15 to 0.44) but did not reach statistical significance. CONCLUSION IOT helped to achieve significant scoliotic curve correction in NMS compared to non-traction group. Despite the overall tendency of improved pelvic obliquity correction, reduced operative time and reduced blood loss as compared to a surgery without the use of IOT, it did not achieve statistical significance. Further studies which are prospective with a larger sample size and focussing on a particular etiology may be conducted which would validate the results. LEVEL OF EVIDENCE IV.

Abstract
AIM In children with neurological complex chronic conditions (CCC) undergoing hip surgery we aimed to: estimate the rate of postoperative pneumonia, determine the effect of pneumonia on postoperative hospital resource use, and identify predictors of postoperative pneumonia. METHOD A retrospective cohort study was conducted utilizing the Pediatric Health Information System database for 2609 children (1081 females, 1528 males) aged 4 years and older with a neurological CCC who underwent hip surgery (i.e. reconstruction surgery or salvage procedure) between 2016 and 2018 in 41 US children's hospitals. Multivariable, mixed-effects logistic regression was used to assess patient characteristics and risk of pneumonia. RESULTS Mean age at hip surgery was 10 years 1 month (SD 4y 8mo). The postoperative pneumonia rate was 1.6% (n=42). Median length of stay (LOS) was longer for children with pneumonia and the 30-day all-cause unplanned readmission rate and costs were higher. Variability in rates of pneumonia ranged from 1.1% to 2.8% across hospitals. Significant predictors of postoperative pneumonia were osteotomy type (p=0.005) and number of chronic conditions (p≤0.001). INTERPRETATION Postoperative pneumonia after hip surgery in children with a neurological CCC is associated with longer LOS, readmissions, and higher costs. Children undergoing pelvic osteotomies and who have multimorbidity need additional clinical support to prevent postoperative pneumonia and decrease resource utilization. WHAT THIS PAPER ADDS Pneumonia is a major postoperative complication in children with neurological complex chronic conditions (CCC). Forty-two (1.6%) children with neurological CCC developed pneumonia after hip surgery. Length of stay, readmissions, and costs were significantly higher in the group with pneumonia. Variability in pneumonia rates existed across hospitals. Predictors of developing pneumonia include osteotomy type and number of CCC.

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
STUDY DESIGN Retrospective cohort. OBJECTIVE To provide a national-level assessment of the short-term outcomes after spinal deformity surgery in pediatric patients with cerebral palsy. METHODS A national, prospectively collected database was queried to identify pediatric (≤18 years) patients with cerebral palsy, who underwent spinal fusion surgery from 2012 to 2017. Separate multivariate analyses were performed for the primary outcomes of interest including extended length of stay (>75th percentile, >8 days), and readmissions within 90 days after the index admission. RESULTS A total of 2856 patients were reviewed. The mean age ± standard deviation was 12.8 ± 2.9 years, and 49.4% of patients were female. The majority of patients underwent a posterior spinal fusion (97.0%) involving ≥8 levels (79.9%) at a teaching hospital (96.6%). Top medical complications (24.5%) included acute respiratory failure requiring mechanical ventilation (11.4%), paralytic ileus (8.2%), and urinary tract infections (4.6%). Top surgical complications (40.7%) included blood transfusion (35.6%), wound complication (4.9%), and mechanical complication (2.7%). The hospital cost for patients with a length of hospital stay >8 days ($113 669) was nearly double than that of those with a shorter length of stay ($68 411). The 90-day readmission rate was 17.6% (mean days to readmission: 30.2). The most common reason for readmission included wound dehiscence (21.1%), surgical site infection (19.1%), other infection (18.9%), dehydration (16.9%), feeding issues (14.5%), and acute respiratory failure (13.1%). Notable independent predictors for 90-day readmissions included preexisting pulmonary disease (odds ratio [OR] 1.5), obesity (OR 3.4), cachexia (OR 27), nonteaching hospital (OR 3.5), inpatient return to operating room (OR 1.9), and length of stay >8 days (OR 1.5). CONCLUSIONS Efforts focused on optimizing the perioperative pulmonary, hematological, and nutritional status as well as reducing wound complications appear to be the most important for improving clinical outcomes.

Abstract
Introduction Spinal fusion for children with neuromuscular scoliosis has been known to improve sitting balance and quality of life as well as for high caregiver satisfaction. However, most studies performed were single surveys, and it remains unclear whether high satisfaction levels are maintained. Thus, in this article, we report the short- and medium-term improvements in caregiver standing assessment after neuromuscular scoliosis surgery in children with Gross Motor Function Classification System (GMFCS) level IV or V. Methods In total, 18 patients with GMFCS levels IV and V were included in this study. The underlying diseases were typical cerebral palsy in 12 cases, chromosomal abnormalities in 5 cases, and congenital myopathy in 1 case. The median age at the time of surgery was 14.5 years. The medians for the first and second follow-up surveys were after 1.4 and 5.9 years, respectively. All the patients had undergone posterior spinal fusion, whereas 12 had undergone pelvic fixation. These patients were assessed using a caregiver questionnaire, in addition to patient demographic data and radiographic assessments. Results The median BMI was 15.4 kg/m2 preoperatively, 16.6 kg/m2 at the first survey, and 17.1 kg/m2 at the second survey. The main Cobb angles were 97.5°, 36.5°, and 37.0° and the spino-pelvic obliquity angles were 22.5°, 6.0°, and 6.5° preoperatively, at the first survey and at the second survey, respectively. In the questionnaire, most domains were rated similarly in the first and second surveys, but the ratings for the “children's QOL” and “digestion and defecation” domains were noted to increase, while that for the “transfer” and “satisfaction with treatment” domains have decreased. Conclusions Neuromuscular scoliosis surgery in children has been associated with extremely high treatment satisfaction in the early postoperative period. However, some caregivers showed a decline in the “transfer” and “treatment satisfaction” domains over time.

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.

An intraoperative laterally placed distractor for gradual load sharing correction of severe spastic neuromuscular spinal deformity. Spine Deform 2021; 9:1137-1144. [PMID: 33689155 DOI: 10.1007/s43390-021-00316-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2020] [Accepted: 02/16/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE To analyze the overall deformity correction for severe neuromuscular scoliosis using laterally placed intra-operative distraction and compare to those receiving standard surgical technique. METHODS This was a retrospective, IRB-approved, cohort study of patients with GMFCS 4 or 5 spastic cerebral palsy with neuromuscular scoliosis, age greater than 10 years, who underwent posterior spinal fusion from 2007 to 2019. All patients had vectored cervical traction with Gardner-Wells tongs, with hips flexed in a relative sitting position. The study cohort underwent intraoperative, laterally placed correction using a distractor placed between two upper ribs and the ipsilateral greater trochanter while the control cohort did not. The 24 study patients were compared to 22 control patients. RESULTS Preoperative comparisons identified significant differences in Cobb angle, preoperative flexibility, and pelvic obliquity with the study group having larger, stiffer deformities with greater obliquity. There were no differences in pre-operative sagittal plane deformity. Mean post-operative upright Cobb angle correction was 67.3° ± 14.8° in the study and 55.3° ± 9.9° in the control group, representing a 66% and 60% correction, respectively. No neurological or other complications were noted from the use of this technique. CONCLUSION The use of a laterally placed distraction device from upper ribs to ipsilateral greater trochanter allowed gradual lateral un-bending of large stiff neuromuscular spine deformities with greater correction than that of standard technique. In this small series, the technique allowed load-sharing during correction, with hips remaining in a functional sitting position, and without neurological complications.

Abstract
BACKGROUND The choice of implants in neuromuscular scoliosis (NMS) surgery remains controversial. Sublaminar polyester bands (SPBs) seem to be a promising alternative implant. The purpose of current study was to compare clinical and radiologic results of posterior instrumentation and fusion using hybrid constructs versus only pedicle screws for NMS treatment. METHODS In 24 patients, pedicle screws were used in all segments, and 18 patients underwent hybrid fixation. Cobb angle, thoracic kyphosis, lumbar lordosis angles, and pelvic obliquity were compared before and immediately after surgery, at the last follow-up radiographs. Demographic, clinical information, duration of surgery, estimated blood loss (EBL), blood transfusion, and complications were compared between groups. Additionally, patients were assessed for pain with visual analog scale (VAS) and quality of life with Short Form 36 (SF-36) and the Oswestry scale. RESULTS Baseline characteristics of patients were similar except for EBL (P = 0.002) and follow-up duration (P = 0.004). The mean curve correction was 58.1% in the hybrid group, and 67.6% in the screw group (P = 0.07), and loss of correction was significantly lower in hybrid group (2.72° ± 1.48° vs. 3.66° ± 1.52°, P = 0.049). Functional scores at final follow-up were equal in both groups (VAS P = 0.865, Oswestry P = 0.097, SF-36 Physical P = 0.358, SF-36 Mental P = 0.145). CONCLUSIONS SPBs might be a better fixation alternative at the apex of rigid spinal deformity in NMS. The deformity can be corrected with less blood loss and at a similar rate of correction, with similar rate complications compared with pedicle screws.

Abstract
Study Design Single-center, retrospective cohort study conducted from 2013 to 2017. Purpose To determine the risk factors for surgical complications in neuromuscular scoliosis based on known patient comorbidities. Overview of Literature The concept of neuromuscular scoliosis includes a wide variety of pathologies affecting the neuromuscular system. Complications are numerous and are often difficult to predict. Methods A retrospective analysis of a single-center database was conducted from 2013 to 2017. Inclusion criteria were patients aged <25 years, diagnosis of neuromuscular scoliosis, and history of posterior fusion deformity surgery. A total of 64 patients (mean age, 15 years; 63% females) were included in this study. Clinical, radiological, and laboratory parameters in the preoperative, intraoperative, and postoperative settings were analyzed. Univariate analysis was performed using Student t -test for continuous variables, and a chi-square test was used for noncontinuous variables. Multivariate analysis was performed to identify predictors of major, mechanical, and total complications. Results Complications were found in 44% of patients, with 46.9% consisting of major complications, and 84.4% being early complications. Univariate analysis revealed that the presence of perinatal comorbidities, independent of other comorbidities, increased the risk for complications (p =0.029). Preoperative hypoglycemia, high number of instrumented levels, longer surgical time, use of an all-screw construct, lower preoperative pelvic obliquity, postoperative lower kyphosis, high thoracic spinopelvic angle (as measured by T9 spino-pelvic inclination), absence of deep drain, and use of superficial drain were associated with postoperative complications (all p <0.05). Logistic regression demonstrated that comorbidities, longer surgical time, hypoglycemia, and absence of deep drains are predictors of complications. Independent variables that predicted major complications were the number of levels fused, postoperative kyphosis (p =0.025; odds ratio [OR], 1.074), and high screw density (p =0.014; OR, 4.380). Conclusions Complications in neuromuscular scoliosis are increased by comorbidities, long surgical time, and inadequate correction. Preventative measures to decrease these complications include appropriate preoperative patient preparation and surgical planning.

Abstract
BACKGROUND Patients with neuromuscular scoliosis (NMS) who undergo posterior spinal fusion (PSF) often have long, protracted hospital stays because of numerous comorbidities. Coordinated perioperative pathways can reduce length of hospitalization (LOH) without increasing complications; however, a subset of patients may not be suited to rapid mobilization and early discharge. METHODS 197 patients with NMS underwent PSF at a single hospital by two surgeons with a post-operative care pathway emphasizing early mobilization, rapid transition to enteral feeds, and discharge prior to first bowel movement. Average LOH was 4.9 days for all patients. Patients were divided into quartiles (< 3 days, 3-5 days, 5-7 days, > 7 days) based on their LOH, and their charts were retrospectively reviewed for preoperative, intraoperative, and postoperative factors associated with their LOH. RESULTS Age at surgery, gender, the need for tube feeds, and specific underlying neuromuscular disorder were not significant predictors of LOH; however, severely involved cerebral palsy (CP) patients (GMFCS 4/5) were more likely to have extended stays than GMFCS 1-3 patients (p = 0.02). Radiographic predictors of LOH included major coronal Cobb angle (p = 0.002) and pelvic obliquity (p = 0.02). Intraoperative predictors included longer surgical times, greater numbers of levels fused and need for intraoperative or postoperative blood transfusion (p < 0.05). The need for ICU admission and development of a pulmonary complication were significantly more likely to fall into the extended LOH group (p < 0.05). CONCLUSIONS Several variables have been identified as significant predictors of LOH after PSF for NMS in the setting of a standardized discharge pathway. Patients with smaller curves and less complex surgeries were more amenable to accelerated discharge. Conversely, patients with severe CP with large curves and pelvic obliquity requiring longer surgeries with more blood loss may not be ideal candidates. These data can be used to inform providers' and families' post-operative expectations. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
ABSTRACT Objective The primary objective of this study was to analyze the prevalence of PJK in patients with neuromuscular scoliosis submitted to posterior spinal arthrodesis with instrumentation. Proximal junctional kyphosis (PJK) is a frequent phenomenon that, due to its importance, began to be studied by several authors, who laid the foundations for the radiographic definition and possible risk factors for its occurrence after long spinal arthrodesis with instrumentation. Despite the large number of PJK studies, most were related to the occurrence of adolescent idiopathic scoliosis, adult deformity and early-onset scoliosis, with few being targeted to patients with congenital and neuromuscular scoliosis. Methods In this study, data from electronic medical records of patients with neuromuscular scoliosis who underwent posterior arthrodesis with instrumentation between the years 2014 and 2016 were analyzed. Information on age, gender, pathology and radiographic measurements were extracted from this sample at the 2nd and 24th postoperative months. Results A total of 39 patients with neuromuscular scoliosis were analyzed. The sample was predominantly male (58.87%) and the mean age was 14.05 years. PJK occurred in 18 patients during the two years following surgery, with a prevalence of 46.15%. The incidence of PJK in the 2nd and 24th postoperative months was 23.1% and 30%, respectively. Conclusions A prevalence of PJK of 46.15% was found in patients with neuromuscular scoliosis treated surgically with posterior instrumentation after two years of follow-up, as compared to previous results .

Abstract
Orthopedic conditions are common in adults with cerebral palsy (CP). Although CP is argued to be a nonprogressive condition of the brain, the musculoskeletal components tend to worsen and deteriorate over time leading to chronic pain, function limitation, and a decline in mobility. Orthopedic care of adults with CP has not been well documented in the literature. This article describes the common orthopedic conditions in adults with CP and discusses who should perform orthopedic surgery on adults.

Abstract
Recent literature suggests that sublaminar bands (SB) can provide good coronal plane correction, comparable to pedicle screw constructs, as well as good correction in the sagittal plane, even in patients with preoperative hypokyphosis; comparable results have been reported in patients with adolescent idiopathic scoliosis (AIS) and in patients with neuromuscular scoliosis (NMS). Two types of SB constructs can be performed: the band-only construct, indicated for non-ambulatory patients with NMS, and the hybrid construct indicted for ambulatory patients with NMS and for patients with AIS. SB are made of polyester or acrylic material and do provide a safe alternative to sublaminar Luque-type wires (stainless steel) as well as an increased contact area between SB and bone allowing higher corrective forces and reduced laminar fracture risk; the use of SB is not associated with increased risk of neurological injury nor with an increased risk of deep postoperative infection. SB used in a hybrid or in a band-only construct in patients with AIS and NMS, appear to be safe in a trained surgeon hands and can achieve well-balanced spine in both coronal and sagittal planes. This article aimed to provide a review of how SB can restore normal frontal and sagittal spine alignment in patients with AIS and NMS.

Abstract
BACKGROUND Complex spinal deformities are a common issue in pediatric patients with an underlying neurologic diagnosis or syndrome. Management of neuromuscular scoliosis is an awesome responsibility, because these patients present with the most challenging pathologies of the deformed spine. Along with surgical correction of the underlying deformity, an intrathecal baclofen (ITB) pump is considered effective in managing the associated spasticity. CASE DESCRIPTION We present the case of an 11-year-old female who sustained an episode of severe ischemic encephalopathy accompanied by hydrocephalus and severe spastic quadriplegia. An ITB pump was inserted to manage spasticity. Two years later, a very severe decompensated spinal curvature developed. In addition, malfunction of the pump was noted, and the decision was made to perform revision along with open hemilaminectomy at the L3-4 level. The inability of cerebrospinal fluid (CSF) to access the pump was verified intraoperatively, with the absence of CSF glow through the intrathecal space demonstrating blockage of CSF flow. CONCLUSIONS The association of cerebral palsy and relevant disorders with the relentless progression of scoliosis is analyzed, along with the possible offending mechanisms. The efficacy of an ITB pump in controlling intractable spasticity associated with neuromuscular scoliosis is reviewed, as well as its potential to accentuate the clinical progression of neuromuscular scoliosis. Although this is an extremely infrequent situation, we must always bear in mind the possibility that malfunction of an ITB pump could be related to obstruction of CSF flow, owing to the extreme severity of the curves established during the course of, most likely untreated, neuromuscular scoliosis.

Abstract
STUDY DESIGN Retrospective cohort. OBJECTIVE To determine how respiratory failure rates and duration of intensive care unit (ICU) stay after posterior spinal fusion (PSF) for neuromuscular scoliosis compare between children with Rett syndrome (RS) versus cerebral palsy (CP). SUMMARY OF BACKGROUND DATA Rett syndrome and CP are associated with high incidence of neuromuscular scoliosis and respiratory dysfunction. METHODS We included 21 patients with RS (mean age, 13 ± 3.1 yrs) and 124 with CP (mean age, 14 ± 3.2 yrs) who underwent PSF by one surgeon from 2004 to 2017. Preoperative motor function was assessed using the Gross Motor Function Classification System (GMFCS). Primary outcomes were respiratory failure and duration of ICU stay. Secondary outcomes were pneumonia and prolonged use of positive pressure ventilation (PPV). Using multivariate regression, we identified associations of age, intraoperative vital signs, duration of hospital stay, number of vertebral levels fused, anesthesia and surgery durations, and estimated blood loss with longer ICU stay and respiratory failure. RESULTS A greater proportion of CP patients (96%) than RS patients (66%) were in GMFCS IV or V (P < 0.01). Respiratory failure was more common in RS patients (43% vs. 19%; P = 0.02), as was PPV (67% vs. 31%; P < 0.01). RS patients had shorter median durations of anesthesia and surgery (P < 0.01). RS patients had a longer median (interquartile range) ICU stay (4 days [1-5] vs. 2 days [2-19]; P = 0.01). Incidence of pneumonia did not differ between groups (P = 0.69). Only RS diagnosis (P = 0.02) and prolonged PPV (P < 0.01) were associated with longer ICU stay. CONCLUSION Despite better preoperative motor function and shorter anesthesia and surgery durations, patients with RS experienced more respiratory failure, prolonged PPV use, and longer ICU stays after PSF than did children with CP.

Abstract
BACKGROUND Implementation of a coordinated multidisciplinary postoperative pathway has been shown to reduce length of stay after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis. This study sought to compare the outcomes of nonambulatory cerebral palsy (CP) patients treated with PSF and cared for using an accelerated discharge (AD) pathway with those using a more traditional discharge (TD) pathway. METHODS A total of 74 patients with Gross Motor Function Classification System (GMFCS) class 4/5 CP undergoing PSF were reviewed. Thirty consecutive patients were cared for using a TD pathway, and 44 patients were subsequently treated using an AD pathway. The cohorts were then evaluated for postoperative complications and length of stay. RESULTS Length of stay (LOS) was 19% shorter in patients managed with the AD pathway (AD 4.0 days [95% CI 2.5-5.5] vs. TD 4.9 days [95% CI 3.5-6.3], p = .01). There was no difference between groups with respect to age at surgery, GMFCS class, preoperative curve magnitude, pelvic obliquity, kyphosis, postoperative curve correction, fusion to the pelvis, or length of fusion between groups. Length of stay remained significantly shorter in the AD group by 0.9 days when controlling for estimated blood loss (EBL) and length of surgery. Complication rates trended lower in the AD group (33% AD vs. 52% TD, p = .12), including pulmonary complications (21% AD vs. 38% TD, p = .13). There was no significant difference in wound complications, return to the operating room, or medical readmissions between groups. CONCLUSIONS Adoption of a standardized postoperative pathway reduced LOS by 19% in nonambulatory CP patients. Overall, complications, including pulmonary, trended lower in the AD group. Early discharge appears to be possible in this challenging patient population. Although the AD pathway may not be appropriate for all patients, the utility of the AD pathway in optimizing care for more routine PSF for this patient subset appears to be worthwhile.

Abstract
BACKGROUND Neuromuscular scoliosis is often treated with posterior spinal fusion, with or without anterior release, and either a same-day or staged, 2-day procedure. METHODS We retrospectively reviewed 222 patients from a prospectively collected, multi-center database of patients with cerebral palsy scoliosis with 2-year follow-up. Baseline characteristics, perioperative, radiographic, and HRQoL measures were compared in six sub-analyses: (1) staged versus same-day surgeries, (2) posterior-only fusion (PSF) versus anterior-posterior spinal fusion (APSF), (3) same-day versus staged PSF, (4) staged versus same-day APSF, (5) same-day PSF versus same-day APSF, (6) staged PSF versus staged APSF. RESULTS Staged patients had larger curves and more pelvic obliquity, longer anesthesia and surgical times, longer hospital and ICU stays (p < 0.001), and more days intubated (p = 0.021). The staged PSF group had larger curves (p = 0.006), longer anesthesia (p = 0.020) and surgeries (p = 0.007), hospital (p = 0.009) and ICU stays (p = 0.028) compared to same-day PSF. The staged APSF group had longer hospital (p < 0.001) and ICU stays (p = 0.004) and anesthesia and surgeries (p < 0.001). Same-day APSF was associated with larger curves (p < 0.002), longer anesthesia (p = 0.012) and surgeries (p = 0.042), greater residual curves (p = 0.035), and greater absolute correction (p = 0.007) compared to same-day PSF. The staged APSF group had longer anesthesia times (p < 0.001) compared to the staged PSF group. No sub-analysis revealed significant differences in baseline characteristics, complications, or HRQoL. CONCLUSION Staged and circumferential approaches tend to be used for greater deformity, but were not associated with superior deformity correction, and were associated with longer operative time, hospital stays, ICU stays, and days intubated. However, for the most severe deformity, other patient factors may play more important roles in treatment decisions given that patients treated with a staged PSF or an APSF, whether staged or not, were similar at baseline.

Abstract
BACKGROUND For large scoliosis, 2 strategies to maximize correction include intraoperative traction and/or anterior release. It is unclear which patients will benefit the most form either approach. The purpose of our study is to compare the radiographic, perioperative clinical outcomes, and health-related quality of life (HRQoL) outcomes of 2 approaches when used in severe neuromuscular scoliosis in the setting of cerebral palsy (CP). METHODS In total, 23 patients with minimum 2-year follow-up, major curves ≥100 degrees, and in whom treatment included posterior spinal fusion were evaluated. Eighteen were treated with posterior spinal fusion with intraoperative traction and 5 with anterior/posterior spinal fusion (APSF). The baseline characteristics, perioperative outcomes, and preoperative and 2-year follow-up data for HRQoL and radiographic measures were compared. RESULTS The groups had similar age, sex, nutritional and seizure status, GMFCS level, and change in CPCHILD scores. The groups had similar curve magnitude (120 vs. 105 degrees, P=0.330) and flexibility (28% vs. 40%, P=0.090), but the APSF group had less pelvic obliquity (POB) (24 vs. 42 degrees, P=0.009). There were similar postoperative major curves (37 vs. 40 degrees, P=0.350), but greater correction in POB (33.5 vs. 14 degrees of correction, P=0.007) in the traction group. The APSF group had longer anesthesia times (669 vs. 415 min, P=0.005), but similar hospital stays, intensive care unit and days intubated, estimated blood loss, cell saver, and red blood cells used. Although the APSF group had twice the rate of complications (22% vs. 40%) during the first 90 days postoperatively, this did not reach statistical significance. CONCLUSIONS Both intraoperative traction and anterior surgery were used to aid correction in severe CP scoliosis. Anterior surgery did not offer superior correction or better HRQoL, and was associated with increased operative times, whereas intraoperative traction was associated with greater correction of POB. Intraoperative traction may be a viable alternative to an anterior release in severe CP scoliosis. LEVEL OF EVIDENCE Level II.

Abstract
STUDY DESIGN A retrospective analysis of a prospective registry. OBJECTIVE Our objective was to prospectively assess caregivers' perceptions regarding changes in the health-related quality of life (HRQL) of patients with cerebral palsy (CP) after spinal arthrodesis. We assessed caregiver perceptions from three perspectives: 1) qualitative assessment of changes in global quality of life, comfort, and health; 2) relative valuation of spine surgery versus other common interventions in CP patients; and 3) quantitative changes in HRQL scores. SUMMARY OF BACKGROUND DATA Studies of children with CP who undergo surgical treatment of spinal deformity have focused largely on radiographic changes. METHODS We queried a multicenter prospective registry of CP patients with level IV or V motor function according to the Gross Motor Function Classification System who were treated with spinal arthrodesis, and whose caregivers completed preoperative and 2-year postoperative qualitative and quantitative HRQL surveys. A total of 212 caregivers and their patients were included in the study. RESULTS At 2-year follow-up, most caregivers reported that patients' global quality of life, comfort, and health were "a lot better" after spinal arthrodesis. Spinal arthrodesis was ranked as the most beneficial intervention in the patients' lives by 74% of caregivers, ahead of hip, knee, and foot surgeries and baclofen pump insertion. Gastrostomy tube insertion was the only intervention ranked superior to spinal arthrodesis in terms of impact. Quantitative HRQL scores improved significantly during 2-year follow-up across various domains. CONCLUSION In qualitative and quantitative HRQL assessments, caregivers reported overall improvement in patients' lives after spinal arthrodesis. Caregivers ranked spine surgery as the most beneficial intervention in the patients' lives, secondary only to gastrostomy tube insertion. LEVEL OF EVIDENCE 2.

Abstract
BACKGROUND Patients with Gross Motor Function Classification System (GMFCS) IV-V cerebral palsy (CP) have significant spasticity and frequently develop scoliosis. Intrathecal baclofen (ITB) pumps are effective in managing spasticity. The effect of ITB therapy on the postoperative course following spinal fusion in patients with GMFCS IV-V CP has not been described. This study sought to compare postoperative recovery, including complications, in patients using ITB therapy with those with no ITB therapy. PURPOSE Evaluate the effect of ITB on the postoperative recovery for patients with GMFCS IV-V CP who undergo spinal fusion for scoliosis. METHODS Health records for patients with GMFCS IV-V CP who underwent a spinal fusion for scoliosis at a major quaternary-care children's hospital from January 2009 to October 2015 were reviewed and relevant data were abstracted. Descriptive statistics and regression models were used to compare patients. RESULTS Sixty-nine patients were included-19 ITB therapy and 50 no ITB therapy. Demographic and operative characteristics were similar across groups. The mean length of stay for patients in the ITB therapy group was 11.2 days and 14.3 days for the no ITB therapy group, with no difference between groups (p = .12). Pain scores in both groups decreased at the same rate, with scores in the ITB therapy group averaging one-half point lower (p = .32). The average amount of morphine equivalents (p = .71) and benzodiazepine equivalents (p = .53) used were similar between groups. Complication rates were significantly different between groups. Four (21%) of the ITB therapy patients had 1 or more complications whereas 28 (56%, p = .01) in the no ITB therapy group had 1 or more complications. The average number of complications per patient in the ITB therapy group was 0.3 (SD: 0.075, range: 0-3) and the no ITB therapy group was 1.1 (SD: 1.1, range: 0-6, p = .01). CONCLUSIONS There was no significant difference in length of stay, pain scores, or pain/spasticity medication use between groups after spinal fusion, but there was a significantly lower incidence of complications in the ITB therapy group.

Abstract
BACKGROUND Series on the learning curve in spinal deformity surgery have been published, but none has addressed neuromuscular spinal deformity, comprised of arguably the most complex cases. We present the first multi-center analysis of the impact of surgeon experience on neuromuscular spinal deformity surgery. METHODS A multi-center prospective study of spinal deformity surgery for cerebral palsy (CP) with at least 2 years of follow-up provided the dataset for assessment. Surgeons were categorized into one of two groups based on their self-reported first year of practice: an experienced surgeons (ES) group included those with at least 10 years of experience at the time of surgery and a young surgeons (YS) group included those with fewer than 10 years of experience at time of surgery. Groups were compared in multiple pre-operative, operative, and post-operative outcomes. RESULTS The YS group had 8 surgeons who performed 59 surgeries; the ES group had 13 surgeons who performed 103 cases, with one surgeon's cases distributed in both groups. The YS group had a greater proportion of patients with severe mental retardation (89.7% vs. 68.6%, p = .01). Duration of surgery was greater in the YS group (456 vs. 344 minutes, p < .001). The mean number of levels fused was greater in the ES group (15.9 vs. 15.6, p = .024), caused by increased variation in the upper level of fusion among the ES group. No significant differences were found between groups for estimated blood loss, length of hospitalization, or in percentage of Cobb correction. Years of experience of the operating surgeon was inversely correlated with duration of surgery (rho = -0.476, p < .001). CONCLUSIONS In performing scoliosis surgery on CP patients, surgeons with fewer than ten years of practice experience demonstrate significantly greater average operative time and decreased mean number of levels fused, yet produce similar clinical outcomes to more experienced surgeons. LEVEL OF EVIDENCE Level III, therapeutic.

Abstract
BACKGROUND The natural history of scoliosis in Duchenne muscular dystrophy (DMD) is progressive and debilitating if neglected. The purpose of this study was to evaluate outcomes related to spinal deformity surgery in patients with DMD over a 30-year period. METHODS This was a single center retrospective study of all operatively treated scoliosis in DMD patients over 30 years. Minimum follow-up was 2 years. Owing to changes in instrumentation over time, patients were divided into 2 groups: Luque or pedicle screws (PS) constructs. Radiographic, perioperative variables, pulmonary function test (preoperatively and postoperatively), and complication data were evaluated. RESULTS There were 60 subjects (Luque: 47, PS: 13). The Luque group was on average 13 years old, 53 kg, and had 7 years of follow-up. Coronal Cobb was 31±12 degrees preoperatively, 16±11 degrees at first postoperatively, and 21±15 degrees at final follow-up (P≤0.001). Pelvic obliquity was 7±6 degrees preoperatively, 5±5 degrees at first postoperatively (P=0.43), and 5±4 degrees at final follow-up (P=0.77). The majority of this group was fused to L5 (45%) or the sacrum (49%). The PS group was on average 14 years old, 65 kg, and had 4 years of follow-up. Coronal Cobb was 43±19 degrees preoperatively, 12±9 degrees at first postoperatively (P≤0.001), and 12±8 degrees at final follow-up. Pelvic obliquity was 6±5 degrees preoperatively, 3±3 degrees at first postoperatively (P=0.06), and 2±2 degrees at final follow-up (P=0.053). The majority were fused to the pelvis (92%). Both groups' pulmonary function declined with time. Both groups had high complication rates (Luque 68%; PS group 54%). The Luque group had more implant-related complications (26%); the PS group had a higher rate of early postoperative infections (23%). CONCLUSIONS Over a 30-year period of operative treatment of scoliosis in DMD, both PS constructs and Luque instrumentation improved coronal Cobb. The PS group had improved and maintained pelvic obliquity. Both groups had high complication rates. LEVEL OF EVIDENCE Level IV-therapeutic.

Abstract
OBJECTIVE To investigate the 5-year outcomes of children with neuromuscular scoliosis treated with sacral-alar-iliac screws. METHODS We reviewed clinical and radiographic records of patients aged ≤18 years treated by 1 pediatric orthopedic surgeon for neuromuscular scoliosis with spinal fusion using sacral-alar-iliac pelvic anchors. Thirty-eight patients with a minimum 5-year radiographic follow-up (mean, 6.0 ± 1.2 years) were studied. The mean patient age was 13 ± 2.0 years, and 47% were female. The mean number of levels fused was 18 ± 0.7. Two-thirds (66%) of the patients were diagnosed with cerebral palsy. RESULTS Between the preoperative period and final follow-up, the patients exhibited a mean correction of the major coronal curve of 79% (preoperative, 85° to final, 18°) and a mean 57% correction of the pelvic obliquity (preoperative, 16° to final, 7°). Patients maintained the correction of mean pelvic obliquity from the early postoperative period (6°) to final follow-up (7°). Preoperatively, 76% of the patients had a pelvic obliquity of >10°, compared with 26% of patients postoperatively. There were no cases of neurologic or vascular complications or pseudarthrosis. Radiographs revealed bilateral sacral-alar-iliac screw lucency in 8 patients; 4 of these patients had deep wound infections, and the other 4 were asymptomatic. Unilateral screw fracture was found in 1 patient with an 8-mm-diameter screw (1.3%; 1 of 76 screws); the patient was observed and remained asymptomatic. There were no cases of set screw displacement, screw back-out, or rod dislodgement. CONCLUSIONS Sacral-alar-iliac screws are safe and effective pelvic anchors for use in children with neuromuscular scoliosis.

Abstract
BACKGROUND The use of bone morphogenetic protein (BMP) has been associated with a number of complications in adult patients. However, this association is less established in children. The aim of this study was to evaluate the safety of BMP use in children by determining the complication rates after BMP use at multiple institutions. METHODS In a retrospective study (2000 to 2013), the medical records of all patients who received BMP at any of the 5 institutions were reviewed. Demographic information, preoperative data, and postoperative follow-up data were collected on those patients who were under the age of 18 at the time of surgery. RESULTS A total of 312 pediatric patients underwent surgery with BMP application during the study period. The surgical procedures consisted of 228 spinal fusions, 39 pars repairs, 33 nonunion repair, and 12 other various procedures. Overall 21% (65/312) of patients who had BMP utilized had a complication. Fifty-five percent (36/65) of patients with a complication required a revision surgery. The average follow-up was 27 months (range, 3 to 96 mo); 80% of patients had a follow-up period of >12 months. The average age at the time of surgery was 13 years (range, 1 to 17 y). Males and females were almost equally represented in the study: 143 males (46%) and 168 females (54%). Of the patients who received BMP, 9% had minor complications and 13% had major complications. Wound dehiscence without infection was the most common minor complication and occurred in 59% (16/27) of patients with minor complications. Infection and implant failures were the most frequent major complications, occurring in 38% (15/39) and 33% (13/39) of patients with major complications, respectively. Five of 312 (2%) patients had neurological injury, 3 of which were only temporary. CONCLUSIONS This multicenter study demonstrates a relatively high rate of complications after the use of BMP in children. However, further study is needed to attribute the complications directly to the use of BMP. LEVEL OF EVIDENCE Level IV.

Abstract
AIM This study aims (1) to evaluate and synthesize the evidence for the postoperative outcomes after scoliosis surgery for children with cerebral palsy (CP), and (2) to identify preoperative risk factors for adverse outcomes after surgery. METHOD Medline, EMBASE, CINAHL, and PubMed were searched for relevant literature. Included studies were assessed for risk of bias using the Cochrane Effective Practice and Organisation of Care tool. Quality of evidence for overall function, quality of life (QoL), gross motor function, caregiver outcomes, deformity correction, and postoperative complications were assessed using GRADE (Grades of Recommendation, Assessment, Development and Evaluation). RESULTS Fifty-one studies met inclusion criteria, including 35 case series designs. Risk of bias was high across all studies. On average good deformity correction was achieved, the trend appears positive for caregiver and QoL outcomes, but there was minimal to no change for gross motor or overall function. Inconsistent measurement limited synthesis. A mean overall complication rate of 38.1% (95% confidence interval 27.3-53.3) was found. The quality of evidence was very low across all functional outcomes. INTERPRETATION Limited high-quality evidence exists for outcomes after scoliosis surgery in children with CP, a procedure associated with a moderately high complication rate. The intervention appears indicated for deformity correction, but currently there is insufficient evidence to make recommendations for this surgery as a way to also improve functional outcomes, caregiver outcomes, and quality of life.

Abstract
STUDY DESIGN A prospective longitudinal cohort. OBJECTIVE The objective of this study was to evaluate changes in caregivers' perceptions of health-related quality of life (HRQOL) and caregiver burden in children with severe cerebral palsy (CP) following spinal fusion. SUMMARY OF BACKGROUND DATA Progressive scoliosis is common in nonambulatory children with CP; the utility of spine fusion has been long debated and prospective evaluations of patient reported outcomes are limited. METHODS Children 3 to 21 years old, gross motor classification system (GMFCS) IV-V CP, scheduled for spine fusion were enrolled consecutively from September 2011 to March 2014. Caregivers completed the CPCHILD and ACEND pre-operatively and at 6 weeks, 3, 6, 12, and 24 months postoperatively. Changes in CPCHILD and ACEND scores from preoperative to 1 and 2 years after surgery were assessed using paired t tests. Correlations between preoperative Cobb angle and CPCHILD and ACEND scores were evaluated using Pearson's correlation analysis. RESULTS Twenty-six GMFCS IV-V CP patients with severe scoliosis treated with spine fusion were included. Mean age was 14 years, 50% male, and 46% had instrumentation to the pelvis. Average preoperative Cobb angle was 68.9° (SD 25.68) with an average improvement of 76%. The CPCHILD score increased by 9.8 points above baseline [95% confidence interval (95% CI): 3.4-16.2] at 1 year postoperatively (P = 0.005). However, at 2 years, the CPCHILD score regressed to baseline (P = 0.40). ACEND scores did not change from baseline scores at 1-year (P = 0.09) and 2-year (P = 0.72) follow-up, reflecting that caregiver burden is little changed by spine fusion. There was no correlation between preoperative Cobb angle and CPCHILD score (P = 0.52) or ACEND score (P = 0.56) at 1-year or 2-year follow-up (P = 0.69, P = 0.90). Children with Cobb angle ≤75° experienced more improvement 1 year after surgery than children with Cobb angle >75°. CONCLUSION HRQOL improves 1 year following spine fusion but regresses to baseline after 2 years. Caregiver burden was unchanged following spine fusion. LEVEL OF EVIDENCE 2.

Abstract
This prospective cohort study investigated radiographic outcomes and complications over time in patients with rigid neuromuscular scoliosis treated with sublaminar bands and Ponte osteotomies. Twenty consecutive patients with neuromuscular scoliosis were treated with sublaminar bands in addition to Ponte osteotomies at and around the apex of the deformity and prospectively included. All curves were rigid, with less than 30% reduction on preoperative bending films. Cobb angle, pelvic obliquity, and shoulder obliquity were significantly corrected (P<0.01). Normal thoracic kyphosis was achieved for 85% of patients at the last follow-up. No intraoperative complications were observed. The association between Ponte osteotomies and sublaminar bands appears to be efficient for the management of rigid neuromuscular deformities in children and adolescents. No death and no permanent neurological impairment, as well as no sublaminar bands associated events were recorded.

Abstract
STUDY DESIGN Retrospective review of prospective registry. OBJECTIVES To assess the following in children with cerebral palsy (CP) who develop deep surgical site infection (DSSI) after spinal fusion: (1) rate of infection recurrence after treatment; (2) treatments used; (3) radiographic outcomes; and (4) differences in Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) scores versus those of children with no infection (NI). SUMMARY OF BACKGROUND DATA Studies show high rates of surgical site infection in patients with CP but do not address late recurrence or quality-of-life effects. METHODS One hundred fifty-one children with CP underwent spinal fusion surgery from 2008 through 2011 and had ≥2-year follow-up. Patients who developed DSSI were compared with patients with NI. Student t tests were used to analyze deformity; analysis of variance was used to analyze CPCHILD scores in both groups preoperatively and at final follow-up. RESULTS Eleven patients developed DSSI. Causative organisms were polymicrobial infection (5 cases), Escherichia coli (2 cases), and Proteus mirabilis, Staphylococcus aureus, Enterococcus faecalis, and Peptostreptococcus (1 case each). All patients underwent irrigation and debridement and received at least 6 weeks of antibiotics. Six had negative-pressure-dressing-assisted wound closure; 5 had primary closure. At mean 4-year follow-up (range, 3-5 years) no patient had recurrent infection. From immediate postoperative to final follow-up, no patient had significant loss of coronal curve (p = .77) or pelvic obliquity (p = .71) correction. However, at final follow-up, comfort and emotions, overall quality-of-life, and total CPCHILD scores in the DSSI group were significantly lower compared with the NI group (p = .005, .022, and .026, respectively). CONCLUSIONS In children with CP who developed DSSI after spinal fusion, there was no recurrence of infection or deformity after infection treatment. CPCHILD scores in patients with DSSI were lower compared with the NI group.

Abstract
The objective of this investigation was to determine the outcome of spine fusion for neuromuscular (NM) scoliosis, using Unit Rod technique, with emphasis on complications related to preoperative general health. Between 1997 and 2007, 96 consecutive patients with neuromuscular scoliosis operated on with Unit Rod instrumentation were retrospectively reviewed. The inclusion criteria were diagnosis of NM scoliosis due to cerebral palsy (CP) and muscular dystrophy (DMD). Patient's preoperative general health, weight, and nutrition were collected. Different radiographic and clinical parameters were evaluated. There were 66 CP patients (59 nonwalking) and 30 DMD patients (24 nonwalking). Mean age at surgery was 16.5 years and 13.9 years, respectively. All radiographic measurements improved significantly. Wound infection rate was 16.7% (11% of reoperation rate in CP; 10% in DMD; 3 hardware removal cases). No pelvic fracture due to rod irritation was observed. Unit Rod technique provides good radiographic and clinical outcomes even if this surgery is associated with a high complication rate. It is a quick, simple, and reliable technique. Perioperative management strategy should decrease postoperative complications and increases outcome. A standardized preoperative patient evaluation and preparation including respiratory capacity and nutritional, digestive, and musculoskeletal status are mandatory prior to surgery.

Abstract
Children who suffer with cerebral palsy (CP) have a significant chance of developing scoliosis during their early years and adolescence. The behavior of this scoliosis is closely associated with the severity of the CP disability and unlike idiopathic scoliosis, it continues to progress beyond skeletal maturity. Conservative measures may slow the progression of the curve, however, surgery remains the only definitive management option. Advances in surgical technique over the last 50 years have provided methods to effectively treat the deformity while also reducing complication rates. The increased risk of surgical complications with these complex patients make decisions about treatment challenging, however with careful pre-operative optimization and post-operative care, surgery can offer a significant improvement in quality of life. This review discusses the development of scoliosis in CP patient, evaluates conservative and surgical treatment options and assesses post-operative outcome.

Abstract
Cerebral palsy patients who undergo posterior spinal instrumentation for scoliosis are at a greater risk of surgical site infection compared to adolescents with idiopathic scoliosis. Many infecting organisms are reported. Risk factors include patients' specific factors, nutritional status as well as surgery related factors. Although surgical management is still controversial, it is always based on irrigation and debridement followed or not by implant removal. The purpose of this paper is to review the pathophysiology of surgical site infection in this patient population and to propose a treatment algorithm, based on a thorough review of the current literature and personal experience.

Abstract
STUDY DESIGN Retrospective review of radiographs and charts (case-only). OBJECTIVE The aim of this study was to describe the long-term outcomes of spine fusion for neuromuscular scoliosis in children below 10 years of age with cerebral palsy (CP). SUMMARY OF BACKGROUND DATA Severely involved children with CP may develop early-onset scoliosis. The outcome of spine fusion is not clear and there are no studies focused on spine fusion in this young patient population. METHODS This is a retrospective review of 33 children who underwent spine fusion with unit-rod instrumentation between 1989 and 2006 for CP neuromuscular scoliosis, aged below 10 years at spine fusion, and with follow-up >5 years. Demographic, medical, and radiographic data were retrospectively assessed. Repeated measure analysis of variance and Kaplan-Meier survival estimates were used for data assessment. RESULTS Thirty-three of 42 patients who underwent spine fusion in this period, 19 boys and 14 girls, met the inclusion criteria. Of 9 patients who were excluded, 3 were lost to follow-up and remaining 6 died within 5 years of surgery. Mean age at surgery was 8.3 years (range, 4.4-9.9 y). Mean follow-up was 9.8 years (range, 5.5-15.8 y). Gross motor function classification system level was V in 31 patients and IV in 2 patients. Thirty-one patients (94%) had seizure disorder, 29 patients (88%) had gastric feeding tubes, and 9 patients (27%) had tracheostomy tubes. Eighty-five percent of the patients had posterior-only surgery. Mean Cobb angles preoperative, immediately postoperative, and at final follow-up were 85, 21, and 24 degrees, respectively. Mean postoperative pelvic obliquity correction was 15±9 degrees (P<0.001). At final follow-up, there was no significant change from the postoperative measurements. Complications included 1 deep wound infection and 10 other problems. Eleven patients (28.2%) died after a mean follow-up of 5.6±3.8 years. CONCLUSIONS In our cohort with early-onset neuromuscular scoliosis, spine fusion was associated with minimal short-term and long-term morbidity, but there was 28% mortality at 10 years of follow-up and 50% predicted mortality at 15 years.

Abstract
BACKGROUND Patients with neuromuscular scoliosis (NMS) can pose treatment challenges related to medical comorbidities and altered spinopelvic anatomy. We reviewed the recent literature regarding evaluation and management of NMS patients and explored areas where further research is needed. METHODS We searched the PubMed database for all papers related to the treatment of NMS published from January 1, 2011 through July 31, 2014, yielding 70 papers. RESULTS A total of 39 papers contributed compelling new findings. Steroid treatment has been most promising in patients with Duchenne muscular dystrophy, leading to a significantly lower death rate, better pulmonary function, and longer independent ambulation. Growing rods in early-onset NMS were shown to result in significant improvements in major Cobb angles and pelvic obliquity, with low complication rates in patients with spinal muscular atrophy but high infection rates in those with cerebral palsy. Early reports of magnetic growing rods in NMS patients are favorable. Intraoperative neural monitoring is variable in this patient population; however, use of transcranial motor-evoked potentials in NMS patients seems to be safe. Blood loss is the highest in NMS patients when compared with all other diagnostic categories. However, tranexamic acid seems to significantly lower intraoperative blood loss. In a multicenter study, patients diagnosed with NMS had the highest surgical-site infection rate at 13.1%. Best-practice guidelines have been created regarding prevention of infection in NMS patients. Preoperative nutritional optimization and postoperative nutritional supplementation seem to help with lowering the infection rate in these patients. CONCLUSIONS There have been major advances in the management of NMS patients, but many challenges remain. Further multicenter studies and randomized clinical trials are needed, particularly in the areas of infection prophylaxis, nutritional optimization, improvement in intraoperative neural monitoring, and prevention of proximal junctional kyphosis.

Abstract
The aim of this study was to estimate the prevalence and patient outcomes of proximal junctional kyphosis (PJK) in pediatric patients and adolescents who received surgical interventions for the treatment of a spinal deformity.Literature was searched in electronic databases, and studies were selected by following précised eligibility criteria. Percent prevalence values of the PJK in individual studies were pooled to achieve a weighted effect size under the random effects model. Subgroup and meta-regression analyses were performed to appraise the factors affecting PJK prevalence.Twenty-six studies (2024 patients) were included in this meta-analysis. Average age of the patients was 13.8 ± 2.75 years of which 32 ± 20 % were males. Average follow-up was 51.6 ± 38.8 (range 17 ± 13 to 218 ± 60) months. Overall, the percent prevalence of PJK (95% confidence interval) was 11.02 (10.5, 11.5) %; P < 0.00001 which was inversely associated with age (meta-regression coefficient: -1.607 [-2.86, -0.36]; 0.014). Revision surgery rate in the patients with PJK was 10%. The prevalence of PJK was positively associated with the proximal junctional angle at last follow-up (coefficient: 2.248; P = 0.012) and the change in the proximal junctional angle from surgery to last follow-up (coefficient: 2.139; P = 0.014) but not with preoperative proximal junctional angle.The prevalence of PJK in the children and adolescent patients is 11%. About 10% of those affected require revision surgery.

Abstract
Minimally invasive surgery (MIS) has been described in the treatment of adolescent idiopathic scoliosis (AIS) and adult scoliosis. The advantages of this approach include less blood loss, shorter hospital stay, earlier mobilization, less tissue disruption, and relatively less pain. However, despite these significant benefits, MIS approach has not been reported in neuromuscular scoliosis patients. This is possibly due to concerns with longer surgery time, which is further increased due to more levels fused and instrumented, challenges of pelvic fixation, size and number of incisions, and prolonged anesthesia. We modified the MIS approach utilized in our AIS patients to be implemented in our neuromuscular patients. Our technique allows easy passage of contoured rods, placement of pedicle screws without image guidance, partial/complete facet resection, and all standard reduction maneuvers. Operative time needed to complete this surgery is comparable to the standard procedure and the majority of our patients have been extubated at the end of procedure, spending 1 day in the PICU and 5-6 days in the hospital. We feel that MIS is not only a feasible but also a superior option in patients with neuromuscular scoliosis. Long-term results are unavailable; however, short-term results have shown multiple benefits of this approach and fewer limitations.

Abstract
INTRODUCTION There is a lack of data in the literature on surgical correction of severe neuromuscular scoliosis in patients with serious extent of cerebral palsy. The purpose of this retrospective cohort study was to analyze the radiological and clinical results after posterior-only instrumentation (group P) and combined anterior-posterior instrumentation (group AP) in severe scoliosis in patients with Gross Motor Function Classification System grades IV and V. MATERIALS AND METHODS All eligible patients who underwent surgery in one institution between 1997 and 2012 were analyzed, and charts, surgical reports, and radiographs were evaluated with a minimum follow-up period of 2 years. RESULTS Fifty-seven patients were included (35 in group P, 22 in group AP), with a median follow-up period of 4.1 years. The preoperative mean Cobb angles were 84° (34 % flexibility) in group P and 109° (27 % flexibility) in group AP. In group P, the Cobb angle was 39° (54 % correction) at discharge and 43° at the final follow-up, while in group AP the figures were 54° (50 % correction) at discharge and 56° at the final follow-up. Major complications occurred in 23 vs. 46 % of the patients, respectively. Preoperative curve flexibility was an important predictor for relative curve correction, independently of the type of surgery. CONCLUSION Posterior-only surgery appears to lead to comparable radiological results, with shorter operating times and shorter intensive-care unit and hospital stays than combined surgery. The duration of surgery was a relevant predictor for complications.

Abstract
PURPOSE A prospective, longitudinal cohort was studied to determine the incidence, consequences, and risk factors of major perioperative complications in patients with cerebral palsy (CP) treated with spinal fusion. There is a wide variety of data available on the complications of spine surgery; however, little exists on the perioperative complications in patients with CP. METHODS A prospective multicenter dataset of consecutive patients with CP treated with spinal fusion was evaluated. All major perioperative complications were identified and stratified into categories: pulmonary, gastrointestinal, other medical, wound infection, neurological, instrumentation related, and unplanned staged surgery. Univariate and multivariate analyses were performed to identify various risk factors for major perioperative complications. RESULTS 127 patients were identified with a mean age of 14.3 ± 2.6 years. Overall, 39.4% of the patients had a major perioperative complication. Occurrence of a complication [no complication (NC), yes complication (YC)] resulted in significantly increased intensive care unit (ICU) (NC = 3.2 days, YC = 7.8 days, p < 0.05) and hospital stays (NC = 7.7 days, YC = 15.6 days, p < 0.05). Variables associated with greater risk of a complication included: increased estimated blood loss (EBL) (p < 0.001), larger preoperative kyphosis (p = 0.05), staged procedures (p < 0.05), a lack of antifibrinolytic use (p < 0.05), and a trend toward lower body mass index (BMI) (p = 0.08). Multivariate regression analysis revealed an increased EBL as independently associated with a major perioperative complication (p < 0.05). CONCLUSIONS In this cohort of patients with CP who underwent spinal fusion, 39.4% experienced a major perioperative complication, with pulmonary being the most common. The occurrence of a major perioperative complication lengthened both ICU and hospital stay. Risk factors for major perioperative complications included greater preoperative kyphosis, staged procedures, a lack of antifibrinolytic use, and increased EBL, with the latter being an independent predictor of a major perioperative complication.

Abstract
BACKGROUND Postoperative radiographs are routinely obtained following surgery for the correction of scoliosis in pediatric patients. The purpose of this study was to comprehensively evaluate the utility of obtaining routine postoperative radiographs in the management of these patients. METHODS A total of 1969 clinic notes and corresponding radiographs regarding 451 consecutive patients with scoliosis (age range, ten to eighteen years) who had surgical correction over a ten-year period at a single institution were retrospectively reviewed. Curve etiology, preoperative curve characteristics, and surgical procedures performed were recorded. All postoperative clinic notes and radiographs were reviewed for abnormalities and changes in treatment course. It was then determined whether clinical signs and symptoms and/or abnormal radiographic findings led to a change in treatment course, which was defined as a therapeutic intervention or further diagnostic testing. RESULTS Of the 451 patients in this study (average age [and standard deviation], 14.7 ± 2.4 years), 72.5% had adolescent idiopathic scoliosis, 23.3% had neuromuscular scoliosis, and 4.2% had other underlying causes of scoliosis. A change in treatment course occurred in the cases of forty-two patients, all of whom had symptomatic findings on postoperative history and physical examination and only fifteen of whom had supportive abnormal findings on postoperative radiographs. Curve etiology and surgical procedures performed had no impact on radiographic utility. A significant increase in utility was seen for radiographs obtained at visits one year or more following surgery compared with those obtained at visits less than one year following surgery (1.7% compared with 0.3%, p = 0.001). The overall sensitivity, specificity, positive predictive value, and negative predictive value of routine postoperative radiographs in guiding treatment course were 35.7%, 98.1%, 28.8%, and 98.6%, respectively. CONCLUSIONS Routine radiographs provide low utility in guiding the course of treatment for asymptomatic pediatric patients following surgery for scoliosis. The results of this study suggest that patient or caregiver complaints, comorbidities, and clinical suspicion should be considered before obtaining radiographs at postoperative visits in order to minimize radiation exposure in pediatric patients and reduce medical costs without compromising care.

Abstract
Children with cerebral palsy are prone to development of musculoskeletal deformities. The underlying neurlogic insult may results in a loss of selective motor control, an increase in underlying muscle tone, and muscle imbalance, which can lead to abnormal deforming forces acting on the immature skeleton. The severely involved child is one who is at increased risk for developing progressive musculoskeletal deformities. Close surveillance and evaluation are key to addressing the underlying deformity and improving and maintaining overall function.

Abstract
PURPOSE A retrospective study involving 65 non-ambulatory patients with hypotonic neuromuscular scoliosis has assessed the effectiveness of a sacral rod/bone onlay technique for extending spinal fusion to the sacrum. METHODS To extend posterior spinal fusion to the sacrum, we used either 1 Harrington rod and 1 Luque L rod with sublaminar wires in 14 patients (Group 1) or two rods with sublaminar wires in 51 patients (Group 2) along with abundant autograft and allograft bone covering the ends of the rods. RESULTS Diagnoses were Duchenne muscular dystrophy 53, spinal muscular atrophy 4, myopathy 3, limb girdle muscular dystrophy 2, infantile FSH muscular dystrophy 1, cerebral palsy 1, and Friedreich ataxia 1. Mean age at surgery was 14.3 years (±2.2, range 10.9-25.2). Radiographic follow-up (2 years post-surgery or greater) was 6.4 years (±4.4, range 2-25.3). Using the onlay technique, all patients fused with no rod breakage or pseudarthrosis. For the entire series, the mean pre-operative scoliosis was 54.7° (±31.1, range 0°-120°) with post-operative correction to 21.8° (±21.7, range 0°-91°) and long-term follow-up 24° (±22.9, range 0°-94°). For pelvic obliquity, pre-operative deformity was 17.3° (±11.3, range 0°-51°) with post-operative correction to 8.9° (±7.8, range 0°-35°) and long-term follow-up 10.1° (±8.1, range 0°-27°). Five required revision at a mean of 3.3 years post-original surgery involving rod shortening at the distal end. One of these had associated infection. CONCLUSION Lumbosacral stability and long-term sitting comfort have been achieved in all patients. Problems can be minimized by positioning the rods firmly against the sacrum at the time of surgery with a relatively short extension beyond the L5-S1 junction. The procedure is valuable in hypotonic non-ambulatory neuromuscular patients whose immobility enhances the success rate for fusion due to diminished stress at the lumbosacral junction. It is particularly warranted for those with osteoporosis and a small, deformed pelvis. Considerable weight loss and lengthy rods not closely apposed to the sacrum at the time of surgery played a major role in patients needing revision.

Abstract
STUDY DESIGN Retrospective comparative cohort study. OBJECTIVES Identify whether there are patient or surgical risk factors to predict the probability of failure of iliac screw fixation after correction of neuromuscular scoliosis. SUMMARY OF BACKGROUND DATA There are high reported failure rates of pelvic fixation in long posterior spinal fusion (PSF) constructs to the sacrum for neuromuscular scoliosis. METHODS Patients aged 5 to 25 years, at a single institution, had PSF to the sacrum from 2001 to 2009 with pelvic fixation using iliac screws. Clinical data were retrospectively reviewed to identify patient and surgical variables related to surgery. Failure of iliac fixation was identified strictly as a broken screw, disengagement of the screw from the connector or the connector from the rod, or set plug failure. Lucency around the screws greater than 2 mm was recorded but not considered a failure. Variables were analyzed in a statistical model to identify predictors of failure. RESULTS A total of 108 patients met inclusion criteria; 100 (38 female and 62 male) had appropriate radiographs and minimum 2-year follow-up (average, 5.5 years). Coronal deformity correction averaged 59%. Most patients (89%) had fill of 6 of 8 possible distal fixation points composed of L4, L5, S1, and ilium bilaterally. Iliac screw failure occurred in 27 patients (27%). The initial single predictor statistical model identified 2 possible predictors of failure (patient: spastic tone; and surgical: absence of distal crosslink). In the multivariable model, spastic tone remained a predictor of failure (p = .0103), whereas absence of distal crosslink bordered on significance (p = .0516). CONCLUSIONS Iliac screw fixation failure is common in patients with long PSF constructs for neuromuscular scoliosis. Spastic tone is a risk factor for failure of pelvic fixation. A distal crosslink may protect against pelvic fixation failure. Alternative techniques for pelvic fixation should be studied in an attempt to improve the failure rates of iliac screw pelvic fixation.

Abstract
OBJECTIVES Gastrointestinal complications are frequent after surgical correction of neuromuscular scoliosis, but the effects of scoliosis surgery on gastric function and upper gastrointestinal symptoms over the long term are unknown. METHODS Thirty-one children (16 spastic, 15 flaccid patients) who underwent surgical correction of neuromuscular scoliosis were included in a prospective follow-up study. Median (range) age at surgery was 14.9 (5-20) years and follow-up time 4.3 (2-8) years. Electrogastrography (n=28), gastric emptying scintigraphy (n=17), and structured upper gastrointestinal symptoms questionnaire (n=26) were evaluated before and after surgery. The results were related to patients' clinical state, type and extent of corrective spinal surgery, and gastrointestinal complications. RESULTS The median main scoliosis curve of 81 degrees (51-129 degrees) was corrected to 25 degrees (1.0-85 degrees) after surgery. In electrogastrogram, power ratio increased from preoperative 1.4 (0.30-11) to postoperative 6.2 (1.2-26) in the spastic group (P=0.008), whereas in the flaccid group, power ratio remained unchanged at 2.2 (0.1-17). Patients with prolonged postoperative paralytic ileus had the most substantial increase in gastric power ratio (P=0.038). Correction of sagittal spinal balance correlated with increased postprandial normogastric activity after surgery (R=0.459; P=0.004). The gastric emptying results, upper gastrointestinal symptoms, and body mass index were not significantly altered after scoliosis surgery. CONCLUSIONS Gastric myoelectrical power increased after surgical correction of spastic neuromuscular scoliosis and was associated with prolonged postoperative paralytic ileus. Correction of poor, stooped spinal balance improved gastric myoelectrical activity. The net effect of scoliosis surgery on gastric emptying, upper gastrointestinal symptoms, and clinical nutritional state was minimal.
