Terjesen T, Vinje S, Kibsgård T. The relationship between hip displacement, scoliosis, and pelvic obliquity in 106 nonambulatory children with cerebral palsy: a longitudinal retrospective population-based study. Acta Orthop 2024; 95:55-60. [PMID: 38288626 PMCID: PMC10825870 DOI: 10.2340/17453674.2024.39915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Accepted: 12/14/2023] [Indexed: 02/01/2024] Open
Abstract
BACKGROUND AND PURPOSE The relationship between hip displacement (HD), pelvic obliquity (PO), and scoliosis in nonambulatory children with cerebral palsy (CP) has not been clearly elucidated. The aims of this population-based study were to examine the prevalence and temporal sequence of these deformities in nonambulatory children with CP and to evaluate how probable it is that severe unilateral HD contributes to development of scoliosis. PATIENTS AND METHODS This longitudinal study comprised 106 nonambulatory children, enrolled in a surveillance program. Pelvic radiographs for measurements of migration percentage (MP) and PO were taken once a year from the diagnosis of HD. Spine radiographs were taken in patients with clinically detected scoliosis. Radiographic follow-up continued until skeletal maturity. RESULTS Clinically significant scoliosis (Cobb angle ≥ 40°) occurred in 60 patients at a mean age of 11.8 years. 65 patients developed clinically significant HD (MP ≥ 40%) at a mean age of 4.8 years. 24 patients had no significant hip or spine deformities, 22 had HD only, 17 had scoliosis only, and 43 had both deformities. HD was diagnosed before scoliosis in all except 1 of the patients with both deformities. 14 of 19 patients with severe unilateral HD (MP ≥ 60%) had scoliosis convexity to the opposite side of the displaced hip. CONCLUSION The combination of scoliosis and HD was frequent, and HD was diagnosed first in almost all the patients. HD might be a contributory cause of scoliosis in patients with severe, unilateral HD, PO, and later scoliosis with convexity to the opposite side.

Abstract
PURPOSE To evaluate the prevalence of scoliosis and the rate of scoliosis progression in children with severe cerebral palsy (CP) at GMFCS levels III-V. METHODS Two hundred and six children (86 girls, 120 boys), born 2002-2008, were recruited from The Norwegian Quality and Surveillance Registry for Cerebral Palsy (NorCP). Inclusion criteria were bilateral CP and GMFCS levels III-V. Scoliosis was evaluated annually by examination of the spine by a physiotherapist. Radiographic examination was performed in children with moderate or severe scoliosis at clinical evaluation. The Cobb angle was used as a measure of curve magnitude. RESULTS Scoliosis, defined as Cobb angle ≥ 10°, occurred in 121 children (59%). Severe scoliosis (Cobb angle ≥ 40°) developed in 80 of the 206 patients (39%) at a mean age of 10.9 years (range 5-16) and was more prevalent in children at GMFCS level V (62%) than at levels IV (19%) and III (6%). Initial Cobb angle, Cobb angle ≥ 30° at age 10 years, and GMFCS level V were independent risk factors for severe scoliosis. In children at GMFCS level V, the rate of scoliosis progression decreased with age from a mean of 9.7° per year at age 3-5 years to 2-3° per year in children ≥ 11 years. CONCLUSIONS The prevalence of scoliosis among children with CP increased with decreasing motor functional level. The most important risk factors for progression of scoliosis were high initial Cobb angle, Cobb angle ≥ 30° at age 10 years, and GMFCS level V.

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.

Predicting the impact of intraoperative halo-femoral traction from preoperative imaging in neuromuscular scoliosis. Spine Deform 2022; 10:679-687. [PMID: 35076899 DOI: 10.1007/s43390-021-00461-w] [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: 01/29/2021] [Accepted: 12/11/2021] [Indexed: 10/19/2022]
Abstract
PURPOSE Intraoperative traction (ITx) has been demonstrated to be a useful adjunct intervention at the time of posterior spinal fusion (PSF) for the treatment of severe neuromuscular scoliosis (NMS) to improve the coronal spinal deformity and pelvic obliquity. The purpose of this study is to determine if preoperative flexibility radiographs can predict the amount of spinal deformity and pelvic obliquity correction at final follow-up. METHODS This was a retrospective analysis of a single-surgeon series who underwent PSF to the pelvis with adjunct ITx for NMS. Database query identified 76 NMS patients, of which 41 met inclusion criteria. Demographic, radiographic and operative data were analyzed. RESULTS Of the 41 study patients, 56% (n = 23) were male and mean age at surgery was 13.6 years. Mean follow-up of 4.1 years (minimum follow-up 2 years). 35 patients had cerebral palsy, 5 patients were syndromic, and 1 patient had myelomeningocele. The average preoperative weight was 35 kg and all were wheelchair ambulators. Total traction applied on average was 49% of the preoperative body weight. Mean preoperative coronal deformity was 91° which improved to 43° at final follow-up (53% correction). Push-supine imaging had the strongest correlation to major coronal deformity outcome at final follow-up (r2 = 0.87, p ≤ 0.0001). Compared to push-supine imaging, there was a mean greater coronal deformity correction of 18 ± 10° (p ≤ 0.0001) at final follow-up. To predict the final coronal deformity, the regression equation was final Cobb angle = 1.13085 + preop push-supine Cobb angle × 0.68830. Mean preoperative pelvic obliquity was 34° which improved to 12° at final follow-up (65% correction). Push-supine imaging had the strongest correlation to pelvic obliquity outcome at final follow-up (r2 = 0.59, p = 0.0001). Compared to push-supine imaging, there was a mean greater pelvic obliquity correction of 3 ± 10° (p = 0.0857) at final follow-up. The regression equation was final POB = 6.42096 + preop push-supine POB × 0.36675. Mean preoperative kyphosis was 70° and 52° at final follow-up (26% correction). CONCLUSION The results of this study demonstrated for preoperative planning that the push-supine flexibility radiograph is most predictive of the coronal deformity and of the pelvic obliquity correction. At final follow-up in this NMS population, there was a mean greater improvement of 18° for coronal deformity versus preoperative push-supine imaging and 3° for pelvic obliquity versus preoperative push-supine imaging. At the time of PSF, ITx is an effective adjunct technique to improve coronal deformity and POB for NMS producing 53% coronal correction, 65% POB correction, and 26% kyphosis correction.

Abstract
Neuromuscular scoliosis is a common deformity seen in patients with neuromuscular diseases. Although rigid thoracolumbosacral orthosis is the most frequently used brace, it has low compliance rates and can lead to complications including skin ulcers. Thus, alternative methods for treating neuromuscular scoliosis are needed. The purpose of this study is to evaluate the clinical effects of a novel flexible brace to prevent the progression of neuromuscular scoliosis.This study is a prospective observational study. Twenty-three patients with neuromuscular scoliosis were enrolled in the study. Among patients diagnosed with neuromuscular disease, spine radiographs were checked for a neuromuscular scoliosis diagnosis. The participants were treated with a novel flexible brace for 6 months. The control group (n = 46) was selected using propensity score matching method from a clinical data warehouse. The Cobb angle was measured and compared between the study and control groups.In the study group, the average Cobb's angle significantly decreased from 47.22 ± 18.9° to 31.8 ± 20.0 when wearing the flexible brace (P < .001). Thus, the correction rate was 36.9%. The annual progression rate was significantly lower in the study group than in the control group (P < .05).The flexible brace showed a significant correction rate of scoliosis in patients with severe neuromuscular diseases. The flexible brace is an alternative treatment modality for patients with neuromuscular scoliosis. Daily application of the flexible brace during the growing period can reduce the degree of fixed deformity in the long term.

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
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
BACKGROUND CONTEXT Surgical site infections (SSIs) are medically devastating and financially costly complications after posterior spinal fusion (PSF) for neuromuscular scoliosis (NMS). Many strategies exist to reduce their occurrence. The efficacy of intraoperative antibiotics in the wound or bone graft is gaining in popularity, but this practice has not been well-studied in the PSF NMS population. PURPOSE To assess the potential utility of intraoperative local antibiotics in patients with NMS undergoing PSF. STUDY DESIGN/SETTING Retrospective review of prospectively collected data. PATIENT SAMPLE Pediatric patients who underwent PSF for NMS were identified from the 2016-2018 National Surgical Quality Improvement Program (NSQIP) pediatric spinal fusion datasets. OUTCOME MEASURES Perioperative adverse outcome variables assed included the occurrence of SSI, renal complications, and adverse hospital metrics. METHODS Patient demographic factors, comorbidities, and the use of intraoperative antibiotics in the wound were recorded (a specifically assessed variable in the dataset). The association between the use of intraoperative antibiotics and the occurrence of adverse outcomes/infection was assessed for the entire study population and higher risk sub-populations. RESULTS In total, 1,990 patients met the inclusion criteria, of which 87% received local antibiotics. Higher risk patients were more likely to receive local antibiotics in the wound as part of their procedure. When controlling for potentially confounding factors, the use of local antibiotics was not statistically significantly associated with any of the studied adverse outcomes for the overall study population. Subgroup analysis of higher risk patient populations (≥13 levels fused, osteotomy performed, prior deformity surgery, nonasthma lung condition) revealed a significantly decreased risk of SSI in patients undergoing ≥13 level fusions (relative risk: 0.48, 95% confidence interval: 0.25-0.91). CONCLUSIONS With no increased overall risks and reduced SSIs in higher risk NMS patients undergoing PSF, the use of intrawound antibiotics appears to be supported by this dataset.

Abstract
Objective: This study aimed to investigate the age at which scoliosis progresses to a severe condition and identify the factors related to severe scoliosis in patients with cerebral palsy. Patients and Methods: This retrospective study included 51 patients aged ≥15 years. The Cobb angle was measured over time using radiographs. Patients were divided into the following groups according to their final Cobb angle: <60°, 60°-100°, and ≥100°. The age at which the Cobb angle was ≥20° in the patients was compared among the groups. Moreover, the age at which a significant difference in the Cobb angle occurred in the groups was considered the age at which the scoliosis worsened. Association of the final Cobb angle with factors such as the location of curve, Gross Motor Functional Classification System (GMFCS), capability of turning over, orthosis use, hip dislocation, tracheotomy, and gastric fistula was examined. Results: The mean age at which the Cobb angle was ≥20° was significantly lower in the ≥100° group. From 9 years of age, a significant difference was noted in the Cobb angle between the <60° group and ≥100° group. Between 13-19 years, a significant difference in the Cobb angle was observed among the three groups. Furthermore, GMFCS, capability of turning over, hip dislocation, and gastric fistula were the factors showing a significant difference among the three groups. Conclusion: Scoliosis progressed to the severe form (Cobb angle ≥100°) at 9 years of age. Moreover, scoliosis is aggravated during the growth period. Severe cerebral palsy with low motor function levels and problems with internal functions was considered the cause of scoliosis deterioration.

Abstract
Neuromuscular disorders (NMDs) are diseases involving the upper and lower motor neurons and muscles. In patients with NMDs, cervical spinal deformities are a very common issue; however, unlike thoracolumbar spinal deformities, few studies have investigated these disorders. The patients with NMDs have irregular spinal curvature caused by poor balance and poor coordination of their head, neck, and trunk. Particularly, cervical deformity occurs at younger age, and is known to show more rigid and severe curvature at high cervical levels. Muscular physiologic dynamic characteristics such as spasticity or dystonia combined with static structural factors such as curvature flexibility can result in deformity and often lead to traumatic spinal cord injury. In addition, postoperative complication rate is higher due to abnormal involuntary movement and muscle tone. Therefore, it is important to control abnormal involuntary movement perioperatively along with strong instrumentation for correction of deformity. Various methods such as botulinum toxin injection, physical therapy, muscle division technique, or intrathecal baclofen pump implant may help control abnormal involuntary movements and improve spinal stability. Surgical management for cervical deformities associated with NMDs requires a multidisciplinary effort and a customized strategy.

Abstract
Despite the fact that children with cerebral palsy may not have any deformities at the time of birth, postural deformities, such as scoliosis, pelvic obliquity, and windswept hip deformity, can appear with increasing age. This may lead to respiratory function deterioration and, in more severe cases, affects survival. To date, postural care is believed to help improve the health and quality of life of children with cerebral palsy. This review provides an overview of the cause and clinical management of postural deformity that is seen in children with cerebral palsy.

Abstract
PURPOSE Cerebral palsy (CP) is a disorder arising from a non-progressive lesion in the developing immature brain with an encephalopathy, that results in various levels of motor and sensory dysfunction. Motor disability of these children can be assessed by the Gross Motor Function Classification System in five levels, and depending on their motor functional capability, the most severely affected children fall into levels IV and V. Children in groups IV and V present a full spectrum of musculoskeletal deformities, among which, scoliosis is the most frequently found spinal deformity that most often requires surgical treatment. However, these are procedures that are usually technically demanding, requiring experienced surgical teams and a multidisciplinary approach. METHODS In order to overcome some of the technical pitfalls that may complicate these complex surgical procedures, the authors have gathered together different tips and tricks that may help surgeons performing surgical correction of spinal deformities in CP children. CONCLUSION Although for these children surgery is a major undertaking, with the multidisciplinary approach and advances of technology, anaesthesia and optimization of pre- and postoperative care, complications are manageable in most cases, improving not only the outcome of surgery but also the patient's quality of life and satisfaction of parents and caretakers.

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 Prospective multicenter comparative study. OBJECTIVES We aimed 1) to survey surgeons and caregivers to rank the surgical indications for spinal fusion of pediatric patients with neuromuscular scoliosis secondary to cerebral palsy in order of importance and 2) to characterize the agreement of surgeons and caregivers on major (top three) indications. SUMMARY OF BACKGROUND DATA Surgery for spinal deformity in children with cerebral palsy is a multifaceted and individualized decision that may lead to miscommunication during informed consent. Little data exist on communication effectiveness between surgeon and caregiver during preoperative discussion. METHODS This is a multicenter, prospective survey of Harms Study Group patient caregivers and their surgeons. Participants ranked their most important of 15 indications in descending level of importance, where the top 3 selections were considered major indications for surgery for the particular patient in question. Demographic and other perioperative factors were recorded. Surgeon-caregiver agreement on major indications was determined, taking into account preoperative factors and intersurgeon differences. RESULTS 126 surgeon-caregiver pairs responded. The greatest percentage agreement that an indication was major was "to improve sitting" (69.0% major, 0.8% nonmajor), followed by "to prevent pulmonary compromise" (33.3% major, 24.6% nonmajor), "to improve pain" (31.7% major, 20.6% nonmajor), and "to improve head control/position" (20.7% major, 69.0% nonmajor). Preoperative pain showed an association with surgeon-caregiver agreement on pain as a major indication (p=.004), and intersurgeon differences in agreement on gastrointestinal and pain considerations existed (p=.002, p=.007, respectively). CONCLUSIONS Surgeon-caregiver agreement is greater where literature support for a particular surgical indication is strong (ie, spinal fusion's known improvement of sitting posture in children with neuromuscular scoliosis). Stronger literature support may bolster surgeons' confidence in recommending a particular procedure, fostering greater communication, understanding, and agreement on surgical necessity between caregivers and surgeons.

Abstract
STUDY DESIGN Retrospective analysis. OBJECTIVE The aim of this study is to compare the safety and efficacy of the apical pedicle subtraction osteotomy (PSO) technique with multiple posterior column osteotomies (PCOs) in nonambulatory patients with severe, rigid neuromuscular scoliosis. SUMMARY OF BACKGROUND DATA Neuromuscular scoliosis frequently causes intolerance to sitting due to pelvic obliquity, trunk decompensation, and associated back and rib impingement pain which diminish the patient's functional capacity. In the case of rigid curves, spinal osteotomy techniques are occasionally required for effective correction. METHODS We retrospectively reviewed our patients with severe and rigid neuromuscular scoliosis with associated pelvic obliquity who were treated with posterior instrumented fusion extending to pelvis with more than 1-year postoperative follow-up. We compared radiological and clinical results of PSO and multiple PCO techniques in severe rigid neuromuscular scoliosis with pelvic obliquity of more than 15° in traction radiograph under general anesthesia. Hospital records were also reviewed for operative time, intraoperative blood loss, amount of blood transfusion, duration of hospital stay, and complications. RESULTS There were 12 patients in the PSO group and 10 patients in the PCO group. There was no significant difference between groups in terms of major curve magnitude, sagittal parameters or pelvic obliquity. Although not statistically significant, PSO technique did trend toward better scoliosis correction (post-op Cobb angle 56.1° vs. 66.7° [P = 0.415]). PSO technique provided a significantly better correction in pelvic obliquity (59% vs. 84%) (P = 0.001). There was no significant difference in average intraoperative blood loss, transfusion, and operative times including anesthesia time, hospital stay, or complications. CONCLUSION PSO may be an option in correction of severe and rigid neuromuscular scoliosis. It provides better correction of pelvic obliquity without increasing operative time, need for transfusion, or duration of hospitalization as compared to multiple apical PCO technique. Traction radiograph under general anesthesia is a valuable tool in surgical decision making. LEVEL OF EVIDENCE 4.

Abstract
BACKGROUND Scoliosis in cerebral palsy (CP) often occurs and causes a disturbance in daily life. The purpose of this study was to investigate the natural history of scoliosis in cerebral palsy and determine risk factors for the progression of scoliosis using multivariate analyses. METHODS We revised 113 patients with CP (47 males and 66 females) who had scoliosis with a curve of at least 10° were reviewed and retrospectively investigated these cases of scoliosis and analyzed the risk factors for the progression of this condition. RESULTS The mean follow-up period was 16.5 years and the mean age at onset of scoliosis was 6.6 years (range: 1-16 years). In 59 patients (52%), the age at onset of scoliosis was under 6 years. On the final radiographs, the mean Cobb angle was 55.1° (range: 10° to 169°). After the age of 20 years, 13 of 40 patients (32.5%) had a progression of over 10° in scoliosis. Multivariate analyses showed the risk factors for the progression of scoliosis to be hip displacement (p = 0.0038), the onset of scoliosis before the age of 6 years (p = 0.0024), and 30° of the Cobb angle before the age of 10 years (p < 0.001). A subtype of CP (spastic quadriplegia) was identified as a potential risk factor. CONCLUSIONS After the age of 20 years, 32.5% patients had a progression of over 10° in scoliosis. Risk factors for the progression of scoliosis in CP included hip displacement, early-onset scoliosis, and Cobb angle of 30° before the age of 10 years.

Abstract
BACKGROUND The true benefits of scoliosis surgery in cerebral palsy (CP) remain uncertain. Our aims were to determine the benefits of spinal fusion according to health-related quality of life (HRQoL) improvement at long-term follow-up and to explore the effect of surgery-related complications on clinical outcomes. METHODS The cases of consecutive patients who had Gross Motor Function Classification System (GMFCS) level-IV or V cerebral palsy with 5-year follow-up from a prospective, longitudinal, multicenter database were analyzed. Caregivers completed the Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) questionnaire and 4 Likert-type anchor questions preoperatively and at 1, 2, and 5 years of follow-up. Data on complications were collected prospectively. Preoperative CPCHILD scores were compared with postoperative scores at the 1, 2, and 5-year follow-up evaluations. Preoperative CPCHILD scores were compared with postoperative scores at the 1, 2, and 5-year follow-up evaluations using repeated-measures analysis of variance (ANOVA). Spearman correlation coefficient was used to explore the association between changes in the CPCHILD at 1, 2, and 5-year follow-up and the reported complications within the follow-up period. Similarly, a comparative analysis between the percentage distribution of the answers to the 4 anchor questions and the reported complications was also performed. RESULTS Sixty-nine patients with a mean age (and standard deviation) of 13.4 ± 2.6 years at enrollment were analyzed. The major Cobb angle was a mean of 81.9° ± 26.7° preoperatively and improved to a mean of 28.7° ± 14.4° at 2 years and 30.7° ± 15.3° at 5 years postoperatively. Significant improvements in CPCHILD personal care, positioning, and comfort domains were noted at all time points. The mean increase in the total score was 7.19 (p < 0.001) at 1 year, and the score gain was maintained at 2 and 5 years postoperatively. The overall complication rate was 46.4% at 1 year, 1.4% between 1 and 2 years, and 4.3% at 2 to 5 years postoperatively, with surgical intervention required in 6 patients within 1 year and in 2 additional patients within 5 years following scoliosis surgery. There was no correlation between complications and CPCHILD scores postoperatively at all time points, with the only exception of a weak correlation (ρ = -0.450, p = 0.002) with CPCHILD comfort score at 1 year after surgery. CONCLUSIONS Scoliosis surgery in patients with CP leads to a significant improvement in HRQoL, which is maintained 5 years following surgery. The substantial complication rate does not correlate with HRQoL changes postoperatively, suggesting that the benefits of surgery outweigh the risks in this fragile population.

Abstract
ABSTRACT Objective: The aim of this study was to evaluate the implications of long waiting times on surgery lists for the treatment of patients with scoliosis. Methods: Radiographs of 87 patients with scoliosis who had been on the waiting list for surgery for more than six months were selected. Two surgeons answered questionnaires analyzing the radiographs when entering the waiting list and the current images of each patient. Results: Data from 87 patients were analyzed. The mean waiting time for surgery was 21.7 months (ranging from seven to 32 months). The average progression of the Cobb angle in the curvature was 21.1 degrees. Delayed surgery implied changes in surgical planning, such as greater need of instrumentation, osteotomies, and double approach. Conclusions: Long waiting lists have a significant negative impact on surgical morbidity of patients with scoliosis, since they increase the complexity of the surgery. Level of evidence: IV. Type of study: Descriptive study.

Abstract
BACKGROUND The objective of this study was to evaluate the performance of a clinical prediction model of neuromuscular scoliosis via external validation. METHODS We analyzed a series of 120 patients (mean age ± standard deviation, 15.7 ± 1.8 years; range: 12 to 18 years) with cerebral palsy, severe motor disorders, and cognitive impairment with and without neuromuscular scoliosis treated in two specialized units (70 patients from Nice, France, and 50 patients from Lublin, Poland) in a cross-sectional, double-blind study. Data on etiology, diagnosis, functional assessments, type of spasticity, epilepsy, scoliosis, and clinical history were collected prospectively between 2005 and 2015. Fisher's exact test and multiple logistic regressions were used to identify influential factors for developing spinal deformity. Thus, we applied a predictive model based on a logistic regression algorithm to predict the probability of scoliosis onset for new patients. RESULTS Children with truncal tone disorders (P = Multivariate logistic regression highlighted previous hip surgery (P = 0.002 ≈ 0.005), intractable epilepsy (P = 0.01 ≈ 0.04) and female gender (0.07) as influent factors in the two cohorts. Average accuracy, sensitivity, and specificity of the predictive model were 74%. CONCLUSIONS We validated a prediction model of neuromuscular scoliosis. In cerebral palsy subjects with the previouslymentioned predictors of scoliosis, the frequency of clinical examinations of spine and spinal x-ray should be increased to easily identify candidates for treatment.

Abstract
BACKGROUND In juveniles with progressive curves, there is debate regarding the use of growth friendly implants versus definitive fusion. This study presents outcomes of juvenile cerebral palsy (CP) scoliosis patients who underwent definitive fusion before age 11. METHODS A review of a prospective, multicenter registry identified patients 10 years and younger who had a definitive posterior fusion for their CP scoliosis. Preoperative and postoperative demographic and radiographic changes were evaluated with descriptive statistics. Repeated measures analysis of variance were utilized to compare outcome scores. RESULTS Fourteen children with a mean age of 9.7 years (8.3 to 10.8 y) and a minimum of 2 years follow-up (range 2 to 3 y) were identified. The mean preoperative curve magnitude and pelvic obliquity was 84±25 degrees (range 63 to 144 degrees) and 25±14 degrees, respectively. All patients were skeletally immature with open triradiate cartilage. Three patients had unit rods with wires while the rest incorporated pedicle screws. Immediately postoperation, the average major curve was 25±17 degrees (P≤0.001, 71% correction rate). At most recent follow-up, the average major curve increased to 30±18 degrees (P≤0.001) for a 65% correction rate. Pelvic obliquity improved to 4±4 degrees (84% correction, P≤0.001) immediately postoperation and to 6±5 degrees (P=0.002) at latest follow-up for a 76% correction rate. None of the patients required revision surgery for progression. From pre to most recent follow-up, the CPchild Health outcome scores improved from 47 to 58 (P=0.019). One patient had a deep infection, and 1 patient had a broken rod that did not require any further treatment. CONCLUSIONS Progressive scoliosis in juvenile CP patients requires the surgeon to balance the need for further growth with the risks of progression or repeated surgical procedures. Our study demonstrates that definitive fusion once the curves approach 90 degrees results in significant radiographic and quality of life improvements, but further follow-up is needed to determine whether those results remain after skeletal maturity.

Abstract
STUDY DESIGN Retrospective, case-matched review. OBJECTIVES Compare a group of individuals with cerebral palsy (CP) who had intrathecal baclofen (ITB) pumps to a group of individuals with CP who did not have ITB pumps in order to determine if there was a difference in the prevalence of new-onset neuromuscular scoliosis, an increased rate of progression of preexisting neuromuscular scoliosis, or an increased rate of posterior spine fusion surgery in skeletally immature individuals with CP who had ITB pumps. SUMMARY OF BACKGROUND DATA Various authors report conflicting findings, with some reporting an increased incidence or prevalence of scoliosis in individuals with CP who have ITB pumps whereas others report no difference in the rate of scoliosis between groups. METHODS Retrospective chart and radiographic case-matched study in which individuals were matched by gender and Gross Motor Function Classification Scale (GMFCS) level. RESULTS We found no difference in the rates of new-onset neuromuscular scoliosis for those with CP and ITB pumps and those without ITB pumps. However, we did see a higher rate of progression as well as an increased rate of posterior spine fusion surgery in individuals with CP who had ITB pumps than for those with CP who did not have an ITB pump. CONCLUSIONS We continue to recommend ITB pump therapy for individuals with severe spasticity associated with CP (GMFCS IV and V). There is a significant risk of complications for individuals in general. The risk of neuromuscular scoliosis is relatively high in this population. Our findings suggest that individuals with CP who have ITB pumps and who do or do not have preexisting scoliosis should be monitored closely for either developing new neuromuscular scoliosis or progression of preexisting scoliosis.

Abstract
OBJECTIVE Selective dorsal rhizotomy (SDR) via limited laminectomy is an effective treatment of lower-extremity spasticity in the pediatric population. Children with spasticity are also at risk for neuromuscular scoliosis; however, specific risk factors for progressive spinal deformity requiring posterior spinal fusion (PSF) after SDR are unknown. The authors' goal was to identify potential risk factors. METHODS The authors performed a retrospective cohort study of patients who underwent SDR via limited laminectomy between 2003 and 2014 and who had at least 1 year of follow-up. They analyzed demographic, clinical, and radiographic variables to elucidate risk factors for progressive neuromuscular scoliosis. The primary outcome was need for PSF. RESULTS One hundred thirty-four patients underwent SDR and had at least 12 months of follow-up (mean 65 months); 48 patients (36%) had detailed pre- and postoperative radiographic data available. The mean age at surgery was 10 years (SD 5.1 years). Eighty-four patients (63%) were ambulatory before SDR, 109 (82%) underwent a single-level laminectomy, and a mean of 53% of the dorsal rootlets from L-1 to S-1 were sectioned. Fifteen patients (11.2%) subsequently required PSF for progressive deformity. Nonambulatory status (p < 0.001) and a preoperative Cobb angle > 30° (p = 0.003) were significantly associated with PSF on univariate analysis, but no statistically significant correlation was found with any clinical or radiographic variable and PSF after SDR on multivariate regression analysis. CONCLUSIONS Patients with preoperative nonambulatory status and Cobb angle > 30° may be at risk for progressive spinal deformity requiring PSF after SDR. These are well-known risk factors for progressive deformity in children with spasticity in general. Although our analysis suggests SDR via limited laminectomy may not significantly accelerate the development of neuromuscular scoliosis, further case-control studies are critical to elucidate the impact of SDR on spinal deformity.

Abstract
Usually, neuromuscular scolioses become clinically symptomatic relatively early and are rapidly progressive even after the end of growth. Without sufficient treatment they lead to a severe reduction of quality of life, to a loss of the ability of walking, standing or sitting as well as to an impairment of the cardiopulmonary system resulting in an increased mortality. Therefore, an intensive interdisciplinary treatment by physio- and ergotherapists, internists, pediatricians, orthotists, and orthopedists is indispensable. In contrast to idiopathic scoliosis the treatment of patients with neuromuscular scoliosis with orthosis is controversially discussed, whereas physiotherapy is established and essential to prevent contractures and to maintain the residual sensorimotor function.Frequently, the surgical treatment of the scoliosis is indicated. It should be noted that only long-segment posterior correction and fusion of the whole deformity leads to a significant improvement of the quality of life as well as to a prevention of a progression of the scoliosis and the development of junctional problems. The surgical intervention is usually performed before the end of growth. A prolonged delay of surgical intervention does not result in an increased height but only in a deformity progression and is therefore not justifiable. In early onset neuromuscular scolioses guided-growth implants are used to guarantee the adequat development. Because of the high complication rates, further optimization of these implant systems with regard to efficiency and safety have to be addressed in future research.

Abstract
PURPOSE To assess reliability and validity of a trunk deformity evaluation method expressed as rotational and lateral lean angles between the upper and the lower trunk and between the lower trunk and the pelvis using 3D positions of six front body surface landmarks. METHODS Inter- and intra-rater reliabilities of the proposed method in adults with typical development (n = 22) were assessed, and its validity was also assessed through correlations between the Cobb angle and the analyzed trunk deformity parameters in adults with severe physical disabilities (n = 22). RESULTS The mean differences between two raters and between the initial and second measures were within 2°. Moderate correlations were found between the Cobb angle and both the upper and the lower trunk lateral lean angle and the upper trunk rotation angle. CONCLUSIONS The proposed trunk deformity evaluation appears to be a reliable and valid approach for bedridden people with physical disabilities.

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
This study aims to identify the risk factors leading to the development of severe scoliosis among children with cerebral palsy. A cross-sectional descriptive study of 70 children (aged 12-18 years) with severe spastic and/or dystonic cerebral palsy treated in a single specialist unit is described. Statistical analysis included Fisher exact test and logistic regression analysis to identify risk factors. Severe scoliosis is more likely to occur in patients with intractable epilepsy ( P = .008), poor gross motor functional assessment scores ( P = .018), limb spasticity ( P = .045), a history of previous hip surgery ( P = .048), and nonambulatory patients ( P = .013). Logistic regression model confirms the major risk factors are previous hip surgery ( P = .001), moderate to severe epilepsy ( P = .007), and female gender ( P = .03). History of previous hip surgery, intractable epilepsy, and female gender are predictors of developing severe scoliosis in children with cerebral palsy. This knowledge should aid in the early diagnosis of scoliosis and timely referral to specialist services.

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
Children with severe types of cerebral palsy use adaptive seating systems to encourage function and assist in delaying the development of deformity. These systems are often assessed for and provided by occupational therapists. However, there has been no unifying policy or theoretical basis on which these systems are provided and research evidence is lacking, with studies tending to be small and non-controlled. The International Classification of Functioning, Disability and Health (World Health Organisation 2001a,b) aims to establish a common language for clinical practice as well as research, while bringing together the opposing social and medical models of health care delivery. This paper suggests that the ICF model is an ideal theoretical basis for adaptive seating system assessment and provision, given that these systems often conflict between the medical model of reducing or delaying impairment of body functions and structures and the social model of children and families accessing life and environmental situations through mobility and seating equipment. The paper considers all the domains of the ICF with regard to the current literature. It concludes that using the model in the context of providing adaptive seating gives occupational therapists both a powerful tool for communicating with children and families as well as managers and a basis for evaluating practice.

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
PURPOSE To compare scoliosis progression in quadriplegic spastic cerebral palsy with and without intrathecal baclofen (ITB) pumps. METHODS A retrospective matched cohort study was conducted. Patients with quadriplegic spastic cerebral palsy, GMFCS level 5, treated with ITB pumps with follow-up >1 year were matched to comparable cases by age and baseline Cobb angle without ITB pumps. Annual and peak coronal curve progression, pelvic obliquity progression and need for spinal fusion were compared. RESULTS ITB group: 25 patients (9 female), mean age at pump insertion 9.4 and Risser 0.9. Initial Cobb angle 25.6° and pelvic tilt 3.2°. Follow-up 4.3 (1.0-7.8) years. Cobb angle at follow-up 76.1° and pelvic tilt 18.9°. Non-ITB group: 25 patients (14 female), mean age at baseline 9.2 and Risser 1.0. Initial Cobb angle 29.7° and pelvic tilt 7.1°. Follow-up 3.5 (1.0-7.5) years. Cobb angle at follow-up 69.1° and pelvic tilt 21.0°. The two groups were statistically similar for baseline age, Cobb angle and Risser grade. Mean curve progression was 13.6°/year for the ITB group vs 12.6°/year for the non-ITB group (p = 0.39). Peak curve progression was similar between the groups. Pelvic tilt progression was comparable; ITB group 4.5°/year vs non-ITB 4.6°/year (p = 0.97). During follow-up 5 patients in the ITB group and 9 in the non-ITB group required spinal fusion surgery for curve progression (p = 0.35). CONCLUSIONS Patients with quadriplegic spastic cerebral palsy with and without ITB pumps showed significant curve progression over time. ITB pumps do not appear to alter the natural history of curve progression in this population.

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 We estimated the annual changes in radiographic indices of the spine in cerebral palsy (CP) patients and analyzed the factors that influence its progression rate. METHODS We included CP patients who had undergone whole-spine radiography more than twice and were followed for at least 1 year. The scoliosis Cobb angle, coronal balance, apical vertebral translation, apical rotation, and pelvic obliquity were measured on anteroposterior (AP) radiographs; thoracic kyphosis and lumbar lordosis angles, and sagittal balance was measured on lateral radiographs; and migration percentage was measured on AP hip radiographs to determine hip instability. For each gross motor function classification system (GMFCS) level, the Cobb angles, apical vertebral translation, coronal and sagittal balance, and pelvic obliquity were adjusted by multiple factors with a linear mixed model. RESULTS A total of 184 patients (774 radiographs) were included in this study. There was no significant annual change in scoliosis Cobb, thoracic kyphosis, and lumbar lordosis angles in the GMFCS level I-II and III groups. In the GMFCS level IV-V group, there was an annual increase of 3.4° in the scoliosis Cobb angle (p = 0.020). The thoracic kyphosis angle increased by 2.2° (p = 0.018) annually in the GMFCS level IV-V group. Apical vertebral translation increased by 5.4 mm (p = 0.029) annually in the GMFCS level IV-V group. Progression of coronal and sagittal balance and pelvic obliquity with aging were not statistically significant. Sex, hip instability, hip surgery, and triradiate cartilage did not affect the progression of scoliosis and the balance of the spine and pelvis. CONCLUSIONS The scoliosis Cobb angle, thoracic kyphosis angle, and apical vertebral translation in the GMFCS level IV-V CP patients progressed with age. These findings can predict radiographic progression of scoliosis in CP patients.

Abstract
Neuromuscular scoliosis is difficult to treat with braces because the collapsing trunk with the spinal deformity cannot tolerate the hard materials used for most orthoses. The dynamic spinal brace (DSB) is a novel three-point support brace used in Japan. We present our preliminary findings of 52 pediatric patients with neuromuscular scoliosis treated using DSBs. A positive correlation was found between the Cobb angle at the initiation of bracing and the degree of scoliosis progression. We concluded that DSBs may be effective for early-stage scoliosis. We also found that DSB improved sitting stability and thereby caregiver satisfaction.

Abstract
Using two types of small, lightweight tri-axial accelerometers, we obtained evidence for the effectiveness of an approach for assessing head-trunk symmetrical or asymmetrical positions during sleep. First, we assessed the accuracy of our monitoring system in five healthy young adults (age range, 22-24 years). The participants wore acceleration monitors on the sternum and forehead; then spent 5 min in six different positions. Once accuracy was confirmed, we assessed head-trunk symmetry during night-time sleep in 10 healthy children (age range, 3-13 years) and 10 young adults (age range, 21-26 years) in their home environments. All participants wore the monitors during one night's sleep in their homes. After computing head-trunk positions using the orientation data obtained by the accelerometers, head and trunk symmetry were evaluated. The head and trunk positions were correctly detected: the positional data from the trunk had 99% agreement, and the data from the head had 96% agreement. Both the young adults and children were observed to spend time with the head-trunk in asymmetric positions; however, the subjects changed position frequently so the asymmetrical postures were mobile. We concluded that the proposed monitoring system is a reliable and valid approach for assessing head-trunk symmetry during sleep at home. Implications for Rehabilitation We propose a head and trunk symmetry monitoring system using accelerometers. The proposed system could accurately identify head and trunk position. Asymmetrical positioning was seen in healthy participants but it was not immobile.

Abstract
STUDY DESIGN Matched cohort. OBJECTIVE To compare the unit rod instrumentation (UR) technique with all-pedicle screw (PS) constructs in the surgical care of scoliosis in Gross Motor Function Classification System IV/V non-ambulatory spastic quadriplegic cerebral palsy patients. SUMMARY OF BACKGROUND DATA Over the past 20 years, there has been a transition from the UR technique to the use of pedicle screws and iliac screws in neuromuscular scoliosis. To date, no head-to-head comparative analysis has been reported between the UR technique and PS constructs for posterior segmental spinal instrumentation and fusion in cerebral palsy patients. METHODS A matched cohort study was performed between 2 tertiary-care pediatric centers: 1 using UR technique and the other PS constructs. Minimum follow-up was 2 years postoperatively (PS 2.5 years, UR 4.6 years, not significant). Fourteen patients were matched from each center based on age (mean age: PS 15.4 years, UR 15.5 years), preoperative pelvic obliquity (mean: PS 33.8°, UR 29.1°) and major coronal Cobb angle (mean: PS 100.9°, UR 100.1°). RESULTS There was posterior-only surgery in 14 of 14 PS and 11 of 14 UR surgeries. The final follow-up Cobb angle was lower in the PS group (13.5° vs. 34.3°, p < .05), with 86.5% correction in the PS group and 65.7% in the UR group. Final follow-up pelvic obliquity was similar (PS 8.5° vs. UR 3.3°; not significant). There were no major complications in the PS group. In the UR group, there was 1 deep infection and 1 reoperation for removal of a prominent sublaminar wire. CONCLUSIONS This is the first study to directly compare UR with PS constructs using matched patient cohorts in this patient population. All-pedicle screw constructs had better correction of coronal Cobb angle, lower blood loss, and shorter hospital stays. There was no difference in the correction of pelvic obliquity, complications, or reoperations.

Suh SW, Suh DH, Kim JW, Park JH, Hong JY. Analysis of sagittal spinopelvic parameters in cerebral palsy. Spine J 2013; 13:882-8. [PMID: 23541886 DOI: 10.1016/j.spinee.2013.02.011] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2011] [Revised: 11/17/2012] [Accepted: 02/08/2013] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Knowledge of sagittal spinopelvic parameters is important for the treatment of cerebral palsy (CP) because they differ in the normal population and can induce symptoms. PURPOSE To analyze the sagittal spinal alignment and the pelvic orientation in CP. STUDY DESIGN Radiological analysis of patients with CP. METHODS The study and control groups comprised 57 CP patients and 24 healthy volunteers, respectively. All the patients underwent lateral radiography of the whole spine including hip joints. The radiographic parameters examined were sacral slope (SS), pelvic tilt (PT), pelvic incidence (PI), S1 overhang (OH), thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), lumbar lordosis (LL1 and 2), and sagittal balance (SB). Statistical analysis was performed to identify the significant differences between the two study groups. In addition, correlations were sought between the parameters and symptoms. RESULTS The PT and OH were significantly smaller in the CP patients, whereas SS, TLK, LL1, LL2, and SB were significantly greater (p<.05). Correlation analysis revealed significant relationships between the sagittal parameters. Specifically, PI was found to be associated with SS, PT, and OH, whereas the spinal parameters LL1 and LL2 were found to be related to TK and SB. Between spine and pelvic parameters, LL1 and LL2 were found to be related to SS, PT, PI, and OH and in addition, SB was found to be related to TLK, LL1, and LL2. An analysis of relations between the symptoms and parameters revealed a positive correlation between the severities of symptoms and PT, OH, and TLK (r=0.300, p=.023; r=0.306, p=.020; r=0.289, p=.029, respectively). CONCLUSIONS A significant difference was observed in the sagittal spinopelvic parameters in the CP and normal control groups and was possibly related to the symptoms. The study shows that the evaluations of sagittal spinopelvic parameters could be useful during the treatment of disorders associated with CP.

The Relationship of Gross Motor Functional Classification Scale Level and Hip Dysplasia on the Pattern and Progression of Scoliosis in Children With Cerebral Palsy. Spine Deform 2013; 1:266-271. [PMID: 27927357 DOI: 10.1016/j.jspd.2013.05.002] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2012] [Revised: 04/16/2013] [Accepted: 05/05/2013] [Indexed: 11/22/2022]
Abstract
PURPOSE The primary aim of the study was to determine whether progression and magnitude of scoliosis were related to the Gross Motor Functional Classification Scale (GMFCS) and whether laterality (and associated pelvic obliquity) of the spinal curvature affected severity of recurrent hip subluxation in patients with cerebral palsy who had undergone varus derotational osteotomy (VDRO). METHODS A total 115 patients underwent VDRO surgery at a single institution between 1980 and 2001. Adequate radiographs were available for 98 patients. Average age at time of VDRO was 6.5 years and follow-up post-VDRO was 8.2 years. Children were divided into lower severity (GMFCS 1-3; 13 patients), high severity (GMFCS 4; 42 patients), and highest severity (GMFCS 5; 43 patients). A single observer measured all spine radiographs using standardized technique. A separate observer measured hip migration index on all pelvis radiographs. RESULTS There was a significant increase in coronal deformity over time in each GMFCS category (p < .0001). The GMFCS 1-3 and GMFCS 4 groups had nearly identical time trends, each increasing at roughly 1° to 2° annually, whereas the GMFCS 5 group increased by 3.5°/year (p = .0153). Increasing Cobb angle was not a significant predictor of severity of recurrent subluxation. Furthermore, there was no significant difference in severity of recurrent hip subluxation when hips were evaluated based on whether they were on the same side as the concavity or convexity of the scoliosis (ie, high or low side of pelvic obliquity). CONCLUSIONS The relationship between GMFCS and rate of scoliosis progression differed between groups. Severity of hip subluxation did not increase significantly over time after VDRO, nor was it significantly related to magnitude or laterality of scoliosis in children in this cohort. SIGNIFICANCE Treatment decisions regarding hip subluxation and scoliosis in patients with cerebral palsy may be made independent of each other.

Abstract
PURPOSE To report a complication of airway obstruction during spinal deformity correction surgery in Duchenne muscular dystrophy (DMD) patient, due to lordoscoliosis, airway malacia, and prone surgical positioning, which was rectified by changing the position of the patient and surgery was successfully completed. CASE DESCRIPTION A 15-year-old boy was diagnosed with DMD and admitted for surgical treatment of thoracolumbar scoliosis. The patient's preoperative Cobb's angle was 79° and the kyphotic angle was -19°. During the initial period of surgery, while in the prone position, peak inspiratory pressure (PIP) suddenly increased from 20-21 to 38-41 cmH2O, wheezing sounds were heard on auscultation of both lungs, and his blood pressure began to fall. Under suspicion of airway problem, intraoperative fiberoptic bronchoscopy was performed which confirmed airway obstruction. Attributing patient's prone position as the cause of airway obstruction, the surgical position of the patient was changed from prone to semi-lateral. After this change, the PIP stabilized to within normal limits (20-23 cmH2O). The surgical correction was successfully completed with a posterior-only pedicle screw by the free-hand technique, with the patient in the semi-lateral position for the rest of surgery. CONCLUSIONS Lordoscoliosis and airway malacia in a patient with DMD can lead to occlusion of the tracheobronchial lumen when the patient is in the prone position. Changing the patient's position from prone to semi-lateral can be of help to reverse this airway obstruction and complete the surgery. Pedicular screw insertion can be safely and effectively carried out in this position using free-hand technique.

Prevalence of complications in neuromuscular scoliosis surgery: a literature meta-analysis from the past 15 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 2012; 22:1230-49. [PMID: 23085815 DOI: 10.1007/s00586-012-2542-2] [Citation(s) in RCA: 109] [Impact Index Per Article: 9.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/30/2012] [Revised: 09/22/2012] [Accepted: 10/02/2012] [Indexed: 12/15/2022]
Abstract
PURPOSE Our objectives were primarily to review the published literature on complications in neuromuscular scoliosis (NMS) surgery and secondarily, by means of a meta-analysis, to determine the overall pooled rates (PR) of various complications associated with NMS surgery. METHODS PubMed and Embase databases were searched for studies reporting the outcomes and complications of NMS surgery, published from 1997 to May 2011. We focused on NMS as defined by the Scoliosis Research Society's classification. We measured the pooled estimate of the overall complication rates (PR) using a random effects meta-analytic model. This model considers both intra- and inter-study variation in calculating PR. RESULTS Systematic review and meta-analysis were performed for 68 cohort and case-control studies with a total of 15,218 NMS patients. Pulmonary complications were the most reported (PR = 22.71 %) followed by implant complications (PR = 12.51 %), infections (PR = 10.91 %), neurological complications (PR = 3.01 %) and pseudoarthrosis (PR = 1.88 %). Revision, removal and extension of implant had highest PR (7.87 %) followed by malplacement of the pedicle screws (4.81 %). Rates of individual studies have moderate to high variability. The studies were heterogeneous in methodology and outcome types, which are plausible explanations for the variability; sensitivity analysis with respect to age at surgery, sample size, publication year and diagnosis could also partly explain this variability. In regard to surgical complications affiliated with various surgical techniques in NMS, the level of evidence of published literature ranges between 2+ to 2-; the subsequent recommendations are level C. CONCLUSION NMS patients have diverse and high complication rates after scoliosis surgery. High PRs of complications warrant more attention from the surgical community. Although the PR of all complications are affected by heterogeneity, they nevertheless provide valuable insights into the impact of methodological settings (sample size), patient characteristics (age at surgery), and continual advances in patient care on complication rates.

Abstract
OBJETIVO: Definir as características demográficas dos pacientes portadores de deformidades secundárias da coluna vertebral que aguardam em fila de espera para tratamento cirúrgico em hospital terciário de alta complexidade. MÉTODOS: As informações foram obtidas através dos prontuários dos pacientes no período previamente definido. Os dados foram selecionados conforme os critérios já apresentados e manipulados estatisticamente. RESULTADOS: O estudo incluiu um total de 170 pacientes, dos quais 94 eram do sexo feminino com idades entre 1 e 58 anos, e 76 do sexo masculino com idade entre 1 e 26 anos. Entre as deformidades encontradas foram identificadas: escolioses congênitas por segmentação (6 ou 3,5%), formação (39 ou 22,9%), mistas (34 ou 20,0%) e complexas (14 ou 8,2%), escolioses neuromusculares por paralisia cerebral (PC) (54 ou 31,8%), miopatia (11 ou 6,5%), artrogripose (2 ou 1,2%) e escolioses por neurofibromatose (10 ou 5,9%). CONCLUSÃO: Existe uma considerável lista de pacientes portadores de deformidades de coluna vertebral que aguardam em fila de espera para tratamento cirúrgico por um período muitas vezes bastante prolongado. Este fato acarreta um problema social de difícil manuseio e quando somadas, escoliose neuromuscular e escoliose congênita são responsáveis pela grande maioria dos casos que aguardam cirurgia.

Abstract
STUDY DESIGN Epidemiological total population study based on a prospective follow-up cerebral palsy (CP) registry. OBJECTIVE To describe the prevalence of scoliosis in a total population of children with CP, to analyze the relation between scoliosis, gross motor function, and CP subtype, and to describe the age at diagnosis of scoliosis. SUMMARY OF BACKGROUND DATA Children with CP have an increased risk of developing scoliosis. The reported incidence varies, partly due to different definitions and study groups. Knowledge of the prevalence and characteristics of scoliosis in an unselected group of children with different CP types and levels of function is important for health care planning and for analyzing the risk in an individual child. METHODS A total population of 666 children with CP, aged 4 to 18 years on January 1, 2008, followed with annual examinations in a health care program was analyzed. Gross Motor Function Classification System (GMFCS) level, CP subtype, age at clinical diagnosis of scoliosis, and the Cobb angle at the first radiographical examination were registered. RESULTS Of the 666 children, 116 (17%) had mild and another 76 (11%) had moderate or severe scoliosis based on clinical examination. Radiographical examination showed a Cobb angle of more than 10° in 54 (8%) children and a Cobb angle of more than 20° in 45 (7%) children. The risk of developing scoliosis increased with GMFCS level and age. In most children, the scoliosis was diagnosed after 8 years of age. Children in GMFCS level IV or V had a 50% risk of having moderate or severe scoliosis by 18 years of age, whereas children in GMFCS level I or II had almost no risk. CONCLUSION The incidence of scoliosis increased with GMFCS level and age. Observed variations related to CP subtype were confounded by the GMFCS, reflecting the different distribution of GMFCS levels in the subtypes. Follow-up programs for early detection of scoliosis should be based on the child's GMFCS level and age.

Abstract
STUDY DESIGN Retrospective study of a prospectively assembled cohort. OBJECTIVE To characterize the survival from subsequent spine surgery and the life survival of patients treated surgically for severe spinal deformity due to neuropathic diseases. SUMMARY OF BACKGROUND DATA Survivorship analysis is widely used to study the natural history of disease processes and of treatments provided, but has very seldom been used to study patients' course after surgery for spinal deformity associated with neuropathic diseases. METHODS Patients with neuropathic spinal deformity treated with primary posterior instrumentation and arthrodesis from 1989 through 2002 were identified and studied by review of charts and radiographs, and by mail survey. Subsequent spine surgery and death events, and the time interval from surgery were identified. Fifteen variables possibly influencing survivorship were studied. RESULTS There were no perioperative deaths, spinal cord injuries, or acute wound infections in the 117 eligible patients. Reoperation and life survival statuses were available for 110 patients (94%) at an average follow-up of 11.89 years (±5.3; range: 2-20.9 yr). Twelve patients (11%) had subsequent spine surgery. Survival from subsequent spine surgery was 91% at 5 years, 90% at 10 and 15 years, and 72% at 20 years. Proximal fixation problems occurred in 4 patients. Twenty-two patients (20%) had died from 4 to 20 years postoperative. Life survival was 98% at 5 years, 89% at 10 years, 81% at 15 years, and 56% at 20 years. The only variable associated with life survival was the occurrence of one or more perioperative complications, P = 0.0032. The younger half of the series at operation (<13.75 yr) was significantly more likely to have one or more perioperative complications, P = 0.0068. Spinal deformity type and magnitude were similar for the younger and older halves of the patients. Life survival of the patients with cerebral-palsy and not-cerebral-palsy upper motor neuron disease was not different. One-hundred-two of 105 were at least satisfied or would have the surgery again for the same condition. CONCLUSION Survival from subsequent spine operation was similar to adolescent idiopathic scoliosis series studied in the same manner. Life survival decline began at 4 years postoperative and was significantly associated with the occurrence of one or more perioperative complications. Even after successful spine deformity surgery, this population's health status is often precarious.

Abstract
Cerebral palsy (CP) spinal deformities encompass a spectrum of deformities that are often initially treated nonoperatively, only to result in progression of scoliotic curves and further morbidity. Various surgical interventions have been devised to address the progressive curvature of the spine. This endeavor cannot be taken lightly and at times can be encumbered by prior treatments such as the use of baclofen pumps or dorsal rhizotomies. Care of these patients requires a multidisciplinary approach and comprehensive preoperative and postoperative management, including nutritional status, orthopedic assessment of functional level with specific emphasis on the hips and pelvic obliquity, and wheelchair modifications. The surgical techniques in CP scoliosis have progressively evolved from the classic Luque-Galveston fixation methods, the use of unit rods, and lately the use of pedicle screws, to modern sacropelvic fixation. With the latter method, the spinal deformity in patients with CP can usually be almost completely corrected.

Abstract
OBJETIVO: Avaliar o uso da prótese vertical expansível de titânio (VEPTR) como opção de tratamento inicial da escoliose em crianças de baixa idade portadoras de paralisia cerebral. MÉTODOS: Foram avaliados 10 pacientes portadores de paralisia cerebral (PC) tratados com VEPTR pelo grupo de escoliose da AACD de São Paulo. Caracterizavam-se por imaturidade esquelética e escoliose progressiva; sem deformidade grave no plano sagital. Realizamos avaliação da curva pelo método de Cobb no pré e pós-operatório e após dois anos de seguimento. RESULTADOS: A correção obtida com o uso do VEPTR no pós-operatório imediato foi em média de 41,4% nas radiografias iniciais sem tração (p = 0,005) e 9,1% (p = 0,055) nas radiografias com tração. Após quatro meses de pós-operatório mantiveram-se ganhos de 27,2% com relação ao início. Houve correção da obliquidade pélvica de 10,2º no pré-operatório para 5,4º em média (p = 0,007). As complicações ocorreram em seis pacientes (60%) e em apenas um paciente foi necessária a retirada do VEPTR. CONCLUSÃO: O VEPTR é um método que obteve correção significativa no tratamento provisório das escolioses na PC, apesar de frequentes complicações de baixa morbidade.
